<h2>ADOdb Data Dictionary Library for PHP</h2>
<p>V5.06 16 Oct 2008 (c) 2000-2010 John Lim (<a
href="mailto:jlim#natsoft.com">jlim#natsoft.com</a>).<br>
AXMLS (c) 2004 ars Cognita, Inc</p>
<p><font size="1">This software is dual licensed using BSD-Style and
LGPL. This means you can use it in compiled proprietary and commercial
products.</font></p>
<p>Useful ADOdb links: <a href="http://adodb.sourceforge.net/#download">Download</a>
&nbsp; <a href="http://adodb.sourceforge.net/#docs">Other Docs</a>
</p>
<p>This documentation describes a PHP class library to automate the
creation of tables, indexes and foreign key constraints portably for
multiple databases. Richard Tango-Lowy and Dan Cech have been kind
enough to contribute <a href="#xmlschema">AXMLS</a>, an XML schema
system for defining databases. You can contact them at
dcech#phpwerx.net and richtl#arscognita.com.</p>
<p>Currently the following databases are supported:</p>
<p> <b>Well-tested:</b> PostgreSQL, MySQL, Oracle, MSSQL.<br>
<b>Beta-quality:</b> DB2, Informix, Sybase, Interbase, Firebird, SQLite.<br>
<b>Alpha-quality:</b> MS Access (does not support DEFAULT values) and
generic ODBC.
</p>
<h3>Example Usage</h3>
<pre> include_once('adodb.inc.php');<br> <font color="#006600"># First create a normal connection</font><br> $db = NewADOConnection('mysql');<br> $db-&gt;Connect(...);<br><br> <font
color="#006600"># Then create a data dictionary object, using this connection</font><br> $dict = <strong>NewDataDictionary</strong>($db);<br><br> <font
color="#006600"># We have a portable declarative data dictionary format in ADOdb, similar to SQL.<br> # Field types use 1 character codes, and fields are separated by commas.<br> # The following example creates three fields: "col1", "col2" and "col3":</font><br> $flds = " <br> <font
color="#663300"><strong> col1 C(32) NOTNULL DEFAULT 'abc',<br> col2 I DEFAULT 0,<br> col3 N(12.2)</strong></font><br> ";<br><br> <font
color="#006600"># We demonstrate creating tables and indexes</font><br> $sqlarray = $dict-&gt;<strong>CreateTableSQL</strong>($tabname, $flds, $taboptarray);<br> $dict-&gt;<strong>ExecuteSQLArray</strong>($sqlarray);<br><br> $idxflds = 'co11, col2';<br> $sqlarray = $dict-&gt;<strong>CreateIndexSQL</strong>($idxname, $tabname, $idxflds);<br> $dict-&gt;<strong>ExecuteSQLArray</strong>($sqlarray);<br></pre>
<h3>More Complex Table Sample</h3>
<p>
The following string will create a table with a primary key event_id and multiple indexes, including one compound index idx_ev1. The ability to define indexes using the INDEX keyword was added in ADOdb 4.94 by Gaetano Giunta.
<pre>
$flds = "
event_id I(11) NOTNULL AUTOINCREMENT PRIMARY,
event_type I(4) NOTNULL <b>INDEX idx_evt</b>,
event_start_date T DEFAULT NULL <b>INDEX id_esd</b>,
event_end_date T DEFAULT '0000-00-00 00:00:00' <b>INDEX id_eted</b>,
event_parent I(11) UNSIGNED NOTNULL DEFAULT 0 <b>INDEX id_evp</b>,
event_owner I(11) DEFAULT 0 <b>INDEX idx_ev1</b>,
event_project I(11) DEFAULT 0 <b>INDEX idx_ev1</b>,
event_times_recuring I(11) UNSIGNED NOTNULL DEFAULT 0,
event_icon C(20) DEFAULT 'obj/event',
event_description X
";
$sqlarray = $db-><b>CreateTableSQL</b>($tablename, $flds);
$dict-><b>ExecuteSQLArray</b>($sqlarray);
</pre>
<h3>Class Factory</h3>
<h4>NewDataDictionary($connection, $drivername=false)</h4>
<p>Creates a new data dictionary object. You pass a database connection object in $connection. The $connection does not have to be actually connected to the database. Some database connection objects are generic (eg. odbtp and odbc). Since 4.53, you can tell ADOdb the actual database with $drivername. E.g.</p>
<pre>
$db = NewADOConnection('odbtp');
$datadict = NewDataDictionary($db, 'mssql'); # force mssql
</pre>
<h3>Class Functions</h3>
<h4>function CreateDatabase($dbname, $optionsarray=false)</h4>
<p>Create a database with the name $dbname;</p>
<h4>function CreateTableSQL($tabname, $fldarray, $taboptarray=false)</h4>
<pre> RETURNS: an array of strings, the sql to be executed, or false<br> $tabname: name of table<br> $fldarray: string (or array) containing field info<br> $taboptarray: array containing table options<br></pre>
<p>The new format of $fldarray uses a free text format, where each
field is comma-delimited.
The first token for each field is the field name, followed by the type
and optional
field size. Then optional keywords in $otheroptions:</p>
<pre> "$fieldname $type $colsize $otheroptions"</pre>
<p>The older (and still supported) format of $fldarray is a
2-dimensional array, where each row in the 1st dimension represents one
field. Each row has this format:</p>
<pre> array($fieldname, $type, [,$colsize] [,$otheroptions]*)</pre>
<p>The first 2 fields must be the field name and the field type. The
field type can be a portable type codes or the actual type for that
database.</p>
<p>Legal portable type codes include:</p>
<pre> C: Varchar, capped to 255 characters.<br> X: Larger varchar, capped to 4000 characters (to be compatible with Oracle). <br> XL: For Oracle, returns CLOB, otherwise the largest varchar size.<br><br> C2: Multibyte varchar<br> X2: Multibyte varchar (largest size)<br><br> B: BLOB (binary large object)<br><br> D: Date (some databases do not support this, and we return a datetime type)<br> T: Datetime or Timestamp accurate to the second.<br> TS: Datetime or Timestamp supporting Sub-second accuracy.<br> Supported by Oracle, PostgreSQL and SQL Server currently. <br> Otherwise equivalent to T.<br>
L: Integer field suitable for storing booleans (0 or 1)<br> I: Integer (mapped to I4)<br> I1: 1-byte integer<br> I2: 2-byte integer<br> I4: 4-byte integer<br> I8: 8-byte integer<br> F: Floating point number<br> N: Numeric or decimal number<br></pre>
<p>The $colsize field represents the size of the field. If a decimal
number is used, then it is assumed that the number following the dot is
the precision, so 6.2 means a number of size 6 digits and 2 decimal
places. It is recommended that the default for number types be
represented as a string to avoid any rounding errors.</p>
<p>The $otheroptions include the following keywords (case-insensitive):</p>
<pre> AUTO For autoincrement number. Emulated with triggers if not available.<br> Sets NOTNULL also.<br> AUTOINCREMENT Same as auto.<br> KEY Primary key field. Sets NOTNULL also. Compound keys are supported.<br> PRIMARY Same as KEY.<br> DEF Synonym for DEFAULT for lazy typists.<br> DEFAULT The default value. Character strings are auto-quoted unless<br> the string begins and ends with spaces, eg ' SYSDATE '.<br> NOTNULL If field is not null.<br> DEFDATE Set default value to call function to get today's date.<br> DEFTIMESTAMP Set default to call function to get today's datetime.<br> NOQUOTE Prevents autoquoting of default string values.<br> CONSTRAINTS Additional constraints defined at the end of the field<br> definition.<br></pre>
<p>The Data Dictonary accepts two formats, the older array
specification:</p>
<pre> $flds = array(<br> array('COLNAME', 'DECIMAL', '8.4', 'DEFAULT' =gt; 0, 'NOTNULL'),<br> array('id', 'I' , 'AUTO'),<br> array('`MY DATE`', 'D' , 'DEFDATE'),<br> array('NAME', 'C' , '32', 'CONSTRAINTS' =gt; 'FOREIGN KEY REFERENCES reftable')<br> );<br></pre>
<p>Or the simpler declarative format:</p>
<pre> $flds = "<font color="#660000"><strong><br> COLNAME DECIMAL(8.4) DEFAULT 0 NOTNULL,<br> id I AUTO,<br> `MY DATE` D DEFDATE,<br> NAME C(32) CONSTRAINTS 'FOREIGN KEY REFERENCES reftable'</strong></font><br> ";<br></pre>
<p>Note that if you have special characters in the field name (e.g. My
Date), you should enclose it in back-quotes. Normally field names are
not case-sensitive, but if you enclose it in back-quotes, some
databases will treat the names as case-sensitive (eg. Oracle) , and
others won't. So be careful.</p>
<p>The $taboptarray is the 3rd parameter of the CreateTableSQL
function. This contains table specific settings. Legal keywords include:</p>
<ul>
<li><b>REPLACE</b><br>
Indicates that the previous table definition should be removed
(dropped)together with ALL data. See first example below. </li>
<li><b>DROP</b><br>
Drop table. Useful for removing unused tables. </li>
<li><b>CONSTRAINTS</b><br>
Define this as the key, with the constraint as the value. See the
postgresql <a href="#foreignkey">example</a> below. Additional constraints defined for the whole
table. You will probably need to prefix this with a comma. </li>
</ul>
<p>Database specific table options can be defined also using the name
of the database type as the array key. In the following example, <em>create
the table as ISAM with MySQL, and store the table in the "users"
tablespace if using Oracle</em>. And because we specified REPLACE, drop
the table first.</p>
<pre> $taboptarray = array('mysql' =gt; 'TYPE=ISAM', 'oci8' =gt; 'tablespace users', 'REPLACE');</pre>
<p><a name=foreignkey></a>You can also define foreign key constraints. The following is syntax
for postgresql:
</p>
<pre> $taboptarray = array('constraints' =gt; ', FOREIGN KEY (col1) REFERENCES reftable (refcol)');</pre>
<h4>function DropTableSQL($tabname)</h4>
<p>Returns the SQL to drop the specified table.</p>
<h4>function ChangeTableSQL($tabname, $flds, $tableOptions=false, $dropOldFlds=false)</h4>
<p>Checks to see if table exists, if table does not exist, behaves like
CreateTableSQL. If table exists, generates appropriate ALTER TABLE
MODIFY COLUMN commands if field already exists, or ALTER TABLE ADD
$column if field does not exist.</p>
<p>The class must be connected to the database for ChangeTableSQL to
detect the existence of the table. Idea and code contributed by Florian
Buzin.</p>
<p>Old fields not defined in $flds are not dropped by default. To drop old fields, set $dropOldFlds to true.
<h4>function RenameTableSQL($tabname,$newname)</h4>
<p>Rename a table. Returns the an array of strings, which is the SQL required to rename a table. Since ADOdb 4.53. Contributed by Ralf Becker.</p>
<h4> function RenameColumnSQL($tabname,$oldcolumn,$newcolumn,$flds='')</h4>
<p>Rename a table field. Returns the an array of strings, which is the SQL required to rename a column. The optional $flds is a complete column-defintion-string like for AddColumnSQL, only used by mysql at the moment. Since ADOdb 4.53. Contributed by Ralf Becker.</p>
<h4>function CreateIndexSQL($idxname, $tabname, $flds,
$idxoptarray=false)</h4>
<pre> RETURNS: an array of strings, the sql to be executed, or false<br> $idxname: name of index<br> $tabname: name of table<br> $flds: list of fields as a comma delimited string or an array of strings<br> $idxoptarray: array of index creation options<br></pre>
<p>$idxoptarray is similar to $taboptarray in that index specific
information can be embedded in the array. Other options include:</p>
<pre> CLUSTERED Create clustered index (only mssql)<br> BITMAP Create bitmap index (only oci8)<br> UNIQUE Make unique index<br> FULLTEXT Make fulltext index (only mysql)<br> HASH Create hash index (only postgres)<br> DROP Drop legacy index<br></pre>
<h4>function DropIndexSQL ($idxname, $tabname = NULL)</h4>
<p>Returns the SQL to drop the specified index.</p>
<h4>function AddColumnSQL($tabname, $flds)</h4>
<p>Add one or more columns. Not guaranteed to work under all situations.</p>
<h4>function AlterColumnSQL($tabname, $flds)</h4>
<p>Warning, not all databases support this feature.</p>
<h4>function DropColumnSQL($tabname, $flds)</h4>
<p>Drop 1 or more columns.</p>

<h4>function MetaColumns($tab, $upper=true, $schema=false)</h4>
<h4>function MetaPrimaryKeys($tab,$owner=false,$intkey=false)</h4>
<h4>function MetaIndexes($table, $primary = false, $owner = false)</h4>
<p>These functions are wrappers for the corresponding functions in the
connection object. However, the table names will be autoquoted by the
TableName function (see below) before being passed to the connection
object.</p>
<h4>function NameQuote($name = NULL)</h4>

<p>Convert between database-independent 'Meta' and database-specific
'Actual' type codes.</p>
<h4>function ExecuteSQLArray($sqlarray, $contOnError = true)</h4>
<pre> RETURNS: 0 if failed, 1 if executed all but with errors, 2 if executed successfully<br> $sqlarray: an array of strings with sql code (no semicolon at the end of string)<br> $contOnError: if true, then continue executing even if error occurs<br></pre>

<h2>ADOdb XML Schema (AXMLS)</h2>
<p>This is a class contributed by Richard Tango-Lowy and Dan Cech that
allows the user to quickly
and easily build a database using the excellent ADODB database library
and a simple XML formatted file.
You can <a href="http://sourceforge.net/projects/adodb-xmlschema/">download
the latest version of AXMLS here</a>.</p>
<h3>Quick Start</h3>
<p>Adodb-xmlschema, or AXMLS, is a set of classes that allow the user
to quickly and easily build or upgrade a database on almost any RDBMS
using the excellent ADOdb database library and a simple XML formatted
schema file. Our goal is to give developers a tool that's simple to
use, but that will allow them to create a single file that can build,
upgrade, and manipulate databases on most RDBMS platforms.</p>
<span style="font-weight: bold;"> Installing axmls</span>
<p>The easiest way to install AXMLS to download and install any recent
version of the ADOdb database abstraction library. To install AXMLS
manually, simply copy the adodb-xmlschema.inc.php file and the xsl
directory into your adodb directory.</p>
<span style="font-weight: bold;"> Using AXMLS in Your Application</span>
<p>There are two steps involved in using AXMLS in your application:
first, you must create a schema, or XML representation of your
database, and second, you must create the PHP code that will parse and
execute the schema.</p>
<p>Let's begin with a schema that describes a typical, if simplistic
user management table for an application.</p>
<pre class="listing"><pre>&lt;?xml version="1.0"?&gt;<br>&lt;schema version="0.2"&gt;<br><br> &lt;table name="users"&gt;<br> &lt;desc&gt;A typical users table for our application.&lt;/desc&gt;<br> &lt;field name="userId" type="I"&gt;<br> &lt;descr&gt;A unique ID assigned to each user.&lt;/descr&gt;<br><br> &lt;KEY/&gt;<br> &lt;AUTOINCREMENT/&gt;<br> &lt;/field&gt;<br> <br> &lt;field name="userName" type="C" size="16"&gt;&lt;NOTNULL/&gt;&lt;/field&gt;<br><br> <br> &lt;index name="userName"&gt;<br> &lt;descr&gt;Put a unique index on the user name&lt;/descr&gt;<br> &lt;col&gt;userName&lt;/col&gt;<br> &lt;UNIQUE/&gt;<br><br> &lt;/index&gt;<br> &lt;/table&gt;<br> <br> &lt;sql&gt;<br> &lt;descr&gt;Insert some data into the users table.&lt;/descr&gt;<br> &lt;query&gt;insert into users (userName) values ( 'admin' )&lt;/query&gt;<br><br> &lt;query&gt;insert into users (userName) values ( 'Joe' )&lt;/query&gt;<br> &lt;/sql&gt;<br>&lt;/schema&gt; <br></pre></pre>
<p>Let's take a detailed look at this schema.</p>
<p>The opening &lt;?xml version="1.0"?&gt; tag is required by XML. The
&lt;schema&gt; tag tells the parser that the enclosed markup defines an
XML schema. The version="0.2" attribute sets <em>the version of the
AXMLS DTD used by the XML schema.</em> </p>
<p>All versions of AXMLS prior to version 1.0 have a schema version of
"0.1". The current schema version is "0.2".</p>
<pre class="listing"><pre>&lt;?xml version="1.0"?&gt;<br>&lt;schema version="0.2"&gt;<br> ...<br>&lt;/schema&gt;<br></pre></pre>
<p>Next we define one or more tables. A table consists of a fields (and
other objects) enclosed by &lt;table&gt; tags. The name="" attribute
specifies the name of the table that will be created in the database.</p>
<pre class="listing"><pre>&lt;table name="users"&gt;<br><br> &lt;desc&gt;A typical users table for our application.&lt;/desc&gt;<br> &lt;field name="userId" type="I"&gt;<br><br> &lt;descr&gt;A unique ID assigned to each user.&lt;/descr&gt;<br> &lt;KEY/&gt;<br> &lt;AUTOINCREMENT/&gt;<br> &lt;/field&gt;<br> <br> &lt;field name="userName" type="C" size="16"&gt;&lt;NOTNULL/&gt;&lt;/field&gt;<br><br> <br>&lt;/table&gt;<br></pre></pre>
<p>This table is called "users" and has a description and two fields.
The description is optional, and is currently only for your own
information; it is not applied to the database.</p>
<p>The first &lt;field&gt; tag will create a field named "userId" of
type "I", or integer. (See the ADOdb Data Dictionary documentation for
a list of valid types.) This &lt;field&gt; tag encloses two special
field options: &lt;KEY/&gt;, which specifies this field as a primary
key, and &lt;AUTOINCREMENT/&gt;, which specifies that the database
engine should automatically fill this field with the next available
value when a new row is inserted.</p>
<p>The second &lt;field&gt; tag will create a field named "userName" of
type "C", or character, and of length 16 characters. The
&lt;NOTNULL/&gt; option specifies that this field does not allow NULLs.</p>
<p>There are two ways to add indexes to a table. The simplest is to
mark a field with the &lt;KEY/&gt; option as described above; a primary
key is a unique index. The second and more powerful method uses the
&lt;index&gt; tags.</p>
<pre class="listing"><pre>&lt;table name="users"&gt;<br> ...<br> <br> &lt;index name="userName"&gt;<br> &lt;descr&gt;Put a unique index on the user name&lt;/descr&gt;<br> &lt;col&gt;userName&lt;/col&gt;<br><br> &lt;UNIQUE/&gt;<br> &lt;/index&gt;<br> <br>&lt;/table&gt;<br></pre></pre>
<p>The &lt;index&gt; tag specifies that an index should be created on
the enclosing table. The name="" attribute provides the name of the
index that will be created in the database. The description, as above,
is for your information only. The &lt;col&gt; tags list each column
that will be included in the index. Finally, the &lt;UNIQUE/&gt; tag
specifies that this will be created as a unique index.</p>
<p>Finally, AXMLS allows you to include arbitrary SQL that will be
applied to the database when the schema is executed.</p>
<pre class="listing"><pre>&lt;sql&gt;<br> &lt;descr&gt;Insert some data into the users table.&lt;/descr&gt;<br> &lt;query&gt;insert into users (userName) values ( 'admin' )&lt;/query&gt;<br><br> &lt;query&gt;insert into users (userName) values ( 'Joe' )&lt;/query&gt;<br>&lt;/sql&gt;<br></pre></pre>
<p>The &lt;sql&gt; tag encloses any number of SQL queries that you
define for your own use.</p>
<p>Now that we've defined an XML schema, you need to know how to apply
it to your database. Here's a simple PHP script that shows how to load
the schema.</p>
<pre class="listing"><pre>&lt;?PHP<br>/* You must tell the script where to find the ADOdb and<br> * the AXMLS libraries.<br> */
require( "path_to_adodb/adodb.inc.php");
require( "path_to_adodb/adodb-xmlschema.inc.php" ); # or adodb-xmlschema03.inc.php
/* Configuration information. Define the schema filename,<br> * RDBMS platform (see the ADODB documentation for valid<br> * platform names), and database connection information here.<br> */<br>$schemaFile = 'example.xml';<br>$platform = 'mysql';<br>$dbHost = 'localhost';<br>$dbName = 'database';<br>$dbUser = 'username';<br>$dbPassword = 'password';<br><br>/* Start by creating a normal ADODB connection.<br> */<br>$db = ADONewConnection( $platform );<br>$db-&gt;Connect( $dbHost, $dbUser, $dbPassword, $dbName );<br><br>/* Use the database connection to create a new adoSchema object.<br> */<br>$schema = new adoSchema( $db );<br><br>/* Call ParseSchema() to build SQL from the XML schema file.<br> * Then call ExecuteSchema() to apply the resulting SQL to <br> * the database.<br> */<br>$sql = $schema-&gt;ParseSchema( $schemaFile );<br>$result = $schema-&gt;ExecuteSchema();<br>?&gt;<br></pre></pre>
<p>Let's look at each part of the example in turn. After you manually
create the database, there are three steps required to load (or
upgrade) your schema.</p>
<p>First, create a normal ADOdb connection. The variables and values
here should be those required to connect to your database.</p>
<pre class="listing"><pre>$db = ADONewConnection( 'mysql' );<br>$db-&gt;Connect( 'host', 'user', 'password', 'database' );<br></pre></pre>
<p>Second, create the adoSchema object that load and manipulate your
schema. You must pass an ADOdb database connection object in order to
create the adoSchema object.</p>
<pre class="listing">$schema = new adoSchema( $db );<br></pre>
<p>Third, call ParseSchema() to parse the schema and then
ExecuteSchema() to apply it to the database. You must pass
ParseSchema() the path and filename of your schema file.</p>
<pre class="listing">$schema-&gt;ParseSchema( $schemaFile ); <br>$schema-&gt;ExecuteSchema();</pre>
<p>Execute the above code and then log into your database. If you've
done all this right, you should see your tables, indexes, and SQL.</p>
<p>You can find the source files for this tutorial in the examples
directory as tutorial_shema.xml and tutorial.php. See the class
documentation for a more detailed description of the adoSchema methods,
including methods and schema elements that are not described in this
tutorial.</p>
<h3>XML Schema Version 3</h3>
<p>In March 2006, we added adodb-xmlschema03.inc.php to the release, which supports version 3 of XML Schema.
The adodb-xmlschema.inc.php remains the same as previous releases, and supports version 2 of XML Schema.
Version 3 provides some enhancements:
<ul>
<li> Support for updating table data during an upgrade.
<li> Support for platform-specific table options and platform negation.
<li> Support for unsigned fields.
<li> Fixed opt and constraint support
<li> Many other fixes such as OPT tag, which allows you to set optional platform settings:
</ul>
<p>Example usage:
<pre>&lt;?xml version="1.0"?>
<b>&lt;schema version="0.3"></b>
&lt;table name="ats_kb">
&lt;descr>ATS KnowledgeBase&lt;/descr>
&lt;opt platform="mysql">TYPE=INNODB&lt;/opt>
&lt;field name="recid" type="I"/>
&lt;field name="organization_code" type="I4"/>
&lt;field name="sub_code" type="C" size="20"/>
etc...
</pre>
<p>To use it, change your code to include adodb-xmlschema03.inc.php.
<h3>Upgrading</h3>
<p>
If your schema version is older, than XSLT is used to transform the
schema to the newest version. This means that if you are using an older
XML schema format, you need to have the XSLT extension installed.
If you do not want to require your users to have the XSLT extension
installed, make sure you modify your XML schema to conform to the
latest version.

<h3>1. Introduction</h3>
<p>Oracle is the most popular commercial database used with PHP. There are many ways of accessing Oracle databases in PHP. These include:</p>
<ul>
<li>The oracle extension</li>
<li>The oci8 extension</li>
<li>PEAR DB library</li>
<li>ADOdb library</li>
</ul>
<p>The wide range of choices is confusing to someone just starting with Oracle and PHP. I will briefly summarize the differences, and show you the advantages of using <a href="http://adodb.sourceforge.net/">ADOdb</a>. </p>
<p>First we have the C extensions which provide low-level access to Oracle functionality. These C extensions are precompiled into PHP, or linked in dynamically when the web server starts up. Just in case you need it, here's a <a href=http://www.oracle.com/technology/tech/opensource/php/apache/inst_php_apache_linux.html>guide to installing Oracle and PHP on Linux</a>.</p>
<table width="75%" border="1" align="center">
<tr valign="top">
<td nowrap><b>Oracle extension</b></td>
<td>Designed for Oracle 7 or earlier. This is obsolete.</td>
</tr>
<tr valign="top">
<td nowrap><b>Oci8 extension</b></td>
<td> Despite it's name, which implies it is only for Oracle 8i, this is the standard method for accessing databases running Oracle 8i, 9i or 10g (and later).</td>
</tr>
</table>
<p>Here is an example of using the oci8 extension to query the <i>emp</i> table of the <i>scott</i> schema with bind parameters:
<pre>
$conn = OCILogon("scott","tiger", $tnsName);
$stmt = OCIParse($conn,"select * from emp where empno > :emp order by empno");
$emp = 7900;
OCIBindByName($stmt, ':emp', $emp);
$ok = OCIExecute($stmt);
while (OCIFetchInto($stmt,$arr)) {
print_r($arr);
echo "&lt;hr>";
}
</pre>
<p>This generates the following output:
<div class=greybg>
Array ( [0] => 7902 [1] => FORD [2] => ANALYST [3] => 7566 [4] => 03/DEC/81 [5] => 3000 [7] => 20 )
<hr />
Array ( [0] => 7934 [1] => MILLER [2] => CLERK [3] => 7782 [4] => 23/JAN/82 [5] => 1300 [7] => 10 )
</div>
<p>We also have many higher level PHP libraries that allow you to simplify the above code. The most popular are <a href="http://pear.php.net/">PEAR DB</a> and <a href="http://adodb.sourceforge.net/">ADOdb</a>. Here are some of the differences between these libraries:</p>
<table width="75%" border="1" align="center">

</tr>
<tr valign="top">
<td>High Speed Extension available</td>
<td>No</td>
<td>Yes. You can install the optional ADOdb extension, which reimplements the most frequently used parts of ADOdb as fast C code. Note that the source code version of ADOdb runs just fine without this extension, and only makes use of the extension if detected.</td>
</tr>
</table>
<p> PEAR DB is good enough for simple web apps. But if you need more power, you can see ADOdb offers more sophisticated functionality. The rest of this article will concentrate on using ADOdb with Oracle. You can find out more about <a href="#connecting">connecting to Oracle</a> later in this guide.</p>
<h4>ADOdb Example</h4>
<p>In ADOdb, the above oci8 example querying the <i>emp</i> table could be written as:</p>
<pre>
include "/path/to/adodb.inc.php";
$db = NewADOConnection("oci8");
$db->Connect($tnsName, "scott", "tiger");
$rs = $db->Execute("select * from emp where empno>:emp order by empno",
array('emp' => 7900));
while ($arr = $rs->FetchRow()) {
print_r($arr);
echo "&lt;hr>";
}
</pre>
<p>The Execute( ) function returns a recordset object, and you can retrieve the rows returned using $recordset-&gt;FetchRow( ). </p>
<p>If we ignore the initial connection preamble, we can see the ADOdb version is much easier and simpler:</p>
<table width="100%" border="1">
<tr valign="top" bgcolor="#FFFFFF">
<td width="50%" bgcolor="#e0e0e0"><b>Oci8</b></td>
<td bgcolor="#e0e0e0"><b>ADOdb</b></td>
</tr>
<tr valign="top" bgcolor="#CCCCCC">
<td><pre><font size="1">$stmt = <b>OCIParse</b>($conn,
"select * from emp where empno > :emp");
$emp = 7900;
<b>OCIBindByName</b>($stmt, ':emp', $emp);
$ok = <b>OCIExecute</b>($stmt);
while (<b>OCIFetchInto</b>($stmt,$arr)) {
print_r($arr);
echo "&lt;hr>";
} </font></pre></td>
<td><pre><font size="1">$recordset = $db-><b>Execute</b>("select * from emp where empno>:emp",
array('emp' => 7900));
while ($arr = $recordset-><b>FetchRow</b>()) {
print_r($arr);
echo "&lt;hr>";
}</font></pre></td>
</tr>
</table>
<p>&nbsp;</p>
<h3>2. ADOdb Query Semantics</h3>
<p>You can also query the database using the standard Microsoft ADO MoveNext( ) metaphor. The data array for the current row is stored in the <i>fields</i> property of the recordset object, $rs.
MoveNext( ) offers the highest performance among all the techniques for iterating through a recordset:
<pre>
$rs = $db->Execute("select * from emp where empno>:emp", array('emp' => 7900));
while (!$rs->EOF) {
print_r($rs->fields);
$rs->MoveNext();
}
</pre>
<p>And if you are interested in having the data returned in a 2-dimensional array, you can use:
<pre>
$arr = $db->GetArray("select * from emp where empno>:emp", array('emp' => 7900));
</pre>
<p>Now to obtain only the first row as an array:
<pre>
$arr = $db->GetRow("select * from emp where empno=:emp", array('emp' => 7900));
</pre>
<p>Or to retrieve only the first field of the first row:
<pre>
$arr = $db->GetOne("select ename from emp where empno=:emp", array('emp' => 7900));
</pre>
<p>For easy pagination support, we provide the SelectLimit function. The following will perform a select query, limiting it to 100 rows, starting from row 201 (row 1 being the 1st row):
<pre>
$offset = 200; $limitrows = 100;
$rs = $db->SelectLimit('select * from table', $limitrows, $offset);
</pre>
<p>The $offset parameter is optional.
<h4>Array Fetch Mode</h4>
<p>When data is being returned in an array, you can choose the type of array the data is returned in.
<ol>
<li> Numeric indexes - use <font size="2" face="Courier New, Courier, mono">$connection-&gt;SetFetchMode(ADODB_FETCH_NUM).</font></li>
<li>Associative indexes - the keys of the array are the names of the fields (in upper-case). Use <font size="2" face="Courier New, Courier, mono">$connection-&gt;SetFetchMode(ADODB_FETCH_ASSOC)</font><font face="Courier New, Courier, mono">.</font></li>
<li>Both numeric and associative indexes - use <font size="2" face="Courier New, Courier, mono">$connection-&gt;SetFetchMode(ADODB_FETCH_BOTH).</font></li>
</ol>
<p>The default is ADODB_FETCH_BOTH for Oracle.</p>
<h4><b>Caching</b></h4>
<p>You can define a database cache directory using $ADODB_CACHE_DIR, and cache the results of frequently used queries that rarely change. This is particularly useful for SQL with complex where clauses and group-by's and order-by's. It is also good for relieving heavily-loaded database servers.</p>
<p>This example will cache the following select statement for 3600 seconds (1 hour):</p>
<pre>
$ADODB_CACHE_DIR = '/var/adodb/tmp';
$rs = $db->CacheExecute(3600, "select names from allcountries order by 1");
</pre>
There are analogous CacheGetArray(
), CacheGetRow( ), CacheGetOne( ) and CacheSelectLimit( ) functions. The first parameter is the number of seconds to cache. You can also pass a bind array as a 3rd parameter (not shown above).
<p>There is an alternative syntax for the caching functions. The first parameter is omitted, and you set the cacheSecs
property of the connection object:
<pre>
$ADODB_CACHE_DIR = '/var/adodb/tmp';
$connection->cacheSecs = 3600;
$rs = $connection->CacheExecute($sql, array('id' => 1));
</pre>
<h3>&nbsp;</h3>
<h3>3. Using Prepare( ) For Frequently Used Statements</h3>
<p>Prepare( ) is for compiling frequently used SQL statement for reuse. For example, suppose we have a large array which needs to be inserted into an Oracle database. The following will result in a massive speedup in query execution (at least 20-40%), as the SQL statement only needs to be compiled once:</p>
<pre>
$stmt = $db->Prepare('insert into table (field1, field2) values (:f1, :f2)');
foreach ($arrayToInsert as $key => $value) {
$db->Execute($stmt, array('f1' => $key, 'f2' => $val);
}
</pre>
<p>&nbsp;</p>
<h3>4. Working With LOBs</h3>
<p>Oracle treats data which is more than 4000 bytes in length specially. These are called Large Objects, or LOBs for short. Binary LOBs are BLOBs, and character LOBs are CLOBs. In most Oracle libraries, you need to do a lot of work to process LOBs, probably because Oracle designed it to work in systems with little memory. ADOdb tries to make things easy by assuming the LOB can fit into main memory. </p>
<p>ADOdb will transparently handle LOBs in <i>select</i> statements. The LOBs are automatically converted to PHP variables without any special coding.</p>
<p>For updating records with LOBs, the functions UpdateBlob( ) and UpdateClob( ) are provided. Here's a BLOB example. The parameters should be self-explanatory:
<pre>
$ok = $db->Execute("insert into aTable (id, name, ablob)
values (aSequence.nextVal, 'Name', null)");
if (!$ok) return LogError($db-&gt;ErrorMsg());
<font color="#006600"># params: $tableName, $blobFieldName, $blobValue, $whereClause</font>
$db->UpdateBlob('aTable', 'ablob', $blobValue, 'id=aSequence.currVal');
</pre>
<p>and the analogous CLOB example:
<pre>
$ok = $db->Execute("insert into aTable (id, name, aclob)
values (aSequence.nextVal, 'Name', null)");
if (!$ok) return LogError($db-&gt;ErrorMsg());
$db->UpdateClob('aTable', 'aclob', $clobValue, 'id=aSequence.currVal');
</pre>
<p>Note that LogError( ) is a user-defined function, and not part of ADOdb.
<p>Inserting LOBs is more complicated. Since ADOdb 4.55, we allow you to do this
(assuming that the <em>photo</em> field is a BLOB, and we want to store $blob_data into
this field, and the primary key is the <em>id</em> field):
<pre>
$sql = <span class="style1">"INSERT INTO photos ( ID, photo) ".
"VALUES ( :id, empty_blob() )".
" RETURNING photo INTO :xx"</span>;
$stmt = $db->PrepareSP($sql);
$db->InParameter($stmt, $<strong>id</strong>, <span class="style1">'id'</span>);
$blob = $db->InParameter($stmt, $<strong>blob_data</strong>, <span class="style1">'xx'</span>,-1, OCI_B_BLOB);
$db->StartTrans();
$ok = $db->Execute($stmt);
$db->CompleteTrans();
</pre>
<p>
<h3>5. REF CURSORs</h3>
<p>Oracle recordsets can be passed around as variables called REF Cursors. For example, in PL/SQL, we could define a function <i>open_tab</i> that returns a REF CURSOR in the first parameter:</p>
<pre>
TYPE TabType IS REF CURSOR RETURN TAB%ROWTYPE;
PROCEDURE open_tab (tabcursor IN OUT TabType,tablenames IN VARCHAR) IS
BEGIN
OPEN tabcursor FOR SELECT * FROM TAB WHERE tname LIKE tablenames;
END open_tab;
</pre>
<p>In ADOdb, we could access this REF Cursor using the ExecuteCursor() function. The following will find
all table names that begin with 'A' in the current schema:
<pre>
$rs = $db->ExecuteCursor("BEGIN open_tab(:refc,'A%'); END;",'refc');
while ($arr = $rs->FetchRow()) print_r($arr);
</pre>
<p>The first parameter is the PL/SQL statement, and the second parameter is the name of the REF Cursor.
</p>
<p>&nbsp;</p>
<h3>6. In and Out Parameters</h3>
<p>The following PL/SQL
stored procedure requires an input variable, and returns a result into an output variable:
<pre>
PROCEDURE data_out(input IN VARCHAR, output OUT VARCHAR) IS
BEGIN
output := 'I love '||input;
END;
</pre>
<p>The following ADOdb code allows you to call the stored procedure:</p>
<pre>
$stmt = $db->PrepareSP("BEGIN adodb.data_out(:a1, :a2); END;");
$input = 'Sophia Loren';
$db->InParameter($stmt,$input,'a1');
$db->OutParameter($stmt,$output,'a2');
$ok = $db->Execute($stmt);
if ($ok) echo ($output == 'I love Sophia Loren') ? 'OK' : 'Failed';
</pre>
<p>PrepareSP( ) is a special function that knows about bind parameters.
The main limitation currently is that IN OUT parameters do not work.
<h4>Bind Parameters and REF CURSORs</h4>
<p>We could also rewrite the REF CURSOR example to use InParameter (requires ADOdb 4.53 or later):
<pre>
$stmt = $db->PrepareSP("BEGIN adodb.open_tab(:refc,:tabname); END;");
$input = 'A%';
$db->InParameter($stmt,$input,'tabname');
$rs = $db->ExecuteCursor($stmt,'refc');
while ($arr = $rs->FetchRow()) print_r($arr);
</pre>
<h4>Bind Parameters and LOBs</h4>
<p>You can also operate on LOBs. In this example, we have IN and OUT parameters using CLOBs.
<pre>
$text = 'test test test';
$sql = "declare rs clob; begin :rs := lobinout(:sa0); end;";
$stmt = $conn -> PrepareSP($sql);
$conn -> InParameter($stmt,$text,'sa0', -1, OCI_B_CLOB); # -1 means variable length
$rs = '';
$conn -> OutParameter($stmt,$rs,'rs', -1, OCI_B_CLOB);
$conn -> Execute($stmt);
echo "return = ".$rs."&lt;br>";
</pre>
<p>Similarly, you can use the constant OCI_B_BLOB to indicate that you are using BLOBs.
<h4>Reusing Bind Parameters with CURSOR_SHARING=FORCE</h4>
<p>Many web programmers do not care to use bind parameters, and prefer to enter the SQL directly. So instead of:</p>
<pre>
$arr = $db->GetArray("select * from emp where empno>:emp", array('emp' => 7900));
</pre>
<p>They prefer entering the values inside the SQL:
<pre>
$arr = $db->GetArray("select * from emp where empno>7900");
</pre>
<p>This reduces Oracle performance because Oracle will reuse compiled SQL which is identical to previously compiled SQL. The above example with the values inside the SQL
is unlikely to be reused. As an optimization, from Oracle 8.1 onwards, you can set the following session parameter after you login:
<pre>
ALTER SESSION SET CURSOR_SHARING=FORCE
</pre>
<p>This will force Oracle to convert all such variables (eg. the 7900 value) into constant bind parameters, improving SQL reuse.</p>

<p>&nbsp;</p>
<h3>7. Dates and Datetime in ADOdb</h3>
<p>There are two things you need to know about dates in ADOdb. </p>
<p>First, to ensure cross-database compability, ADOdb assumes that dates are returned in ISO format (YYYY-MM-DD H24:MI:SS).</p>
<p>Secondly, since Oracle treats dates and datetime as the same data type, we decided not to display the time in the default date format. So on login, ADOdb will set the NLS_DATE_FORMAT to 'YYYY-MM-DD'. If you prefer to show the date and time by default, do this:</p>
<pre>
$db = NewADOConnection('oci8');
$db->NLS_DATE_FORMAT = 'RRRR-MM-DD HH24:MI:SS';
$db->Connect($tns, $user, $pwd);
</pre>
<p>Or execute:</p>
<pre>$sql = quot;ALTER SESSION SET NLS_DATE_FORMAT = 'RRRR-MM-DD HH24:MI:SS'&quot;;
$db-&gt;Execute($sql);
</pre>
<p>If you are not concerned about date portability and do not use ADOdb's portability layer, you can use your preferred date format instead.
<p>
<h3>8. Database Portability Layer</h3>
<p>ADOdb provides the following functions for portably generating SQL functions
as strings to be merged into your SQL statements:</p>
<table width="75%" border="1" align=center>
<tr>
<td width=30%><b>Function</b></td>
<td><b>Description</b></td>
</tr>
<tr>
<td>DBDate($date)</td>
<td>Pass in a UNIX timestamp or ISO date and it will convert it to a date
string formatted for INSERT/UPDATE</td>
</tr>
<tr>
<td>DBTimeStamp($date)</td>
<td>Pass in a UNIX timestamp or ISO date and it will convert it to a timestamp
string formatted for INSERT/UPDATE</td>
</tr>
<tr>
<td>SQLDate($date, $fmt)</td>
<td>Portably generate a date formatted using $fmt mask, for use in SELECT
statements.</td>
</tr>
<tr>
<td>OffsetDate($date, $ndays)</td>
<td>Portably generate a $date offset by $ndays.</td>
</tr>
<tr>
<td>Concat($s1, $s2, ...)</td>
<td>Portably concatenate strings. Alternatively, for mssql use mssqlpo driver,
which allows || operator.</td>
</tr>
<tr>
<td>IfNull($fld, $replaceNull)</td>
<td>Returns a string that is the equivalent of MySQL IFNULL or Oracle NVL.</td>
</tr>
<tr>
<td>Param($name)</td>
<td>Generates bind placeholders, using ? or named conventions as appropriate.</td>
</tr>
<tr><td>$db->sysDate</td><td>Property that holds the SQL function that returns today's date</td>
</tr>
<tr><td>$db->sysTimeStamp</td><td>Property that holds the SQL function that returns the current
timestamp (date+time).
</td>
</tr>
<tr>
<td>$db->concat_operator</td><td>Property that holds the concatenation operator
</td>
</tr>
<tr><td>$db->length</td><td>Property that holds the name of the SQL strlen function.
</td></tr>
<tr><td>$db->upperCase</td><td>Property that holds the name of the SQL strtoupper function.
</td></tr>
<tr><td>$db->random</td><td>Property that holds the SQL to generate a random number between 0.00 and 1.00.
</td>
</tr>
<tr><td>$db->substr</td><td>Property that holds the name of the SQL substring function.
</td></tr>
</table>
<p>ADOdb also provides multiple oracle oci8 drivers for different scenarios:</p>
<table width="75%" border="1" align="center">
<tr>
<td nowrap><b>Driver Name</b></td>
<td><b>Description</b></td>
</tr>
<tr>
<td>oci805 </td>
<td>Specifically for Oracle 8.0.5. This driver has a slower SelectLimit( ).</td>
</tr>
<tr>
<td>oci8</td>
<td>The default high performance driver. The keys of associative arrays returned in a recordset are upper-case.</td>
</tr>
<tr>
<td>oci8po</td>
<td> The portable Oracle driver. Slightly slower than oci8. This driver uses ? instead of :<i>bindvar</i> for binding variables, which is the standard for other databases. Also the keys of associative arrays are in lower-case like other databases.</td>
</tr>
</table>
<p>Here's an example of calling the <i>oci8po</i> driver. Note that the bind variables use question-mark:</p>
<pre>$db = NewADOConnection('oci8po');
$db-&gt;Connect($tns, $user, $pwd);
$db-&gt;Execute(&quot;insert into atable (f1, f2) values (?,?)&quot;, array(12, 'abc'));</pre>
<p>&nbsp;<a name=connecting></a>
<h3>9. Connecting to Oracle</h3>
<p>Before you can use ADOdb, you need to have the Oracle client installed and setup the oci8 extension. This extension comes pre-compiled for Windows (but you still need to enable it in the php.ini file). For information on compiling the oci8 extension for PHP and Apache on Unix, there is an excellent guide at <a href="http://www.oracle.com/technology/tech/opensource/php/apache/inst_php_apache_linux.html">oracle.com</a>. </p>
<h4>Should You Use Persistent Connections</h4>
<p>One question that is frequently asked is should you use persistent connections to Oracle. Persistent connections allow PHP to recycle existing connections, reusing them after the previous web pages have completed. Non-persistent connections close automatically after the web page has completed. Persistent connections are faster because the cost of reconnecting is expensive, but there is additional resource overhead. As an alternative, Oracle allows you to pool and reuse server processes; this is called <a href="http://www.cise.ufl.edu/help/database/oracle-docs/server.920/a96521/manproc.htm#13132">Shared Server</a> (also known as MTS).</p>
<p>The author's benchmarks suggest that using non-persistent connections and the Shared Server configuration offer the best performance. If Shared Server is not an option, only then consider using persistent connections.</p>
<h4>Connection Examples</h4>
<p>Just in case you are having problems connecting to Oracle, here are some examples:</p>
<p>a. PHP and Oracle reside on the same machine, use default SID, with non-persistent connections:</p>
<pre> $conn = NewADOConnection('oci8');
$conn-&gt;Connect(false, 'scott', 'tiger');</pre>
<p>b. TNS Name defined in tnsnames.ora (or ONAMES or HOSTNAMES), eg. 'myTNS', using persistent connections:</p>
<pre> $conn = NewADOConnection('oci8');
$conn-&gt;PConnect(false, 'scott', 'tiger', 'myTNS');</pre>
<p>or</p>
<pre> $conn-&gt;PConnect('myTNS', 'scott', 'tiger');</pre>
<p>c. Host Address and SID</p>
<pre>
$conn->connectSID = true;
$conn-&gt;Connect('192.168.0.1', 'scott', 'tiger', 'SID');</pre>
<p>d. Host Address and Service Name</p>
<pre> $conn-&gt;Connect('192.168.0.1', 'scott', 'tiger', 'servicename');</pre>
<p>e. Oracle connection string:
<pre> $cstr = "(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=$host)(PORT=$port))
(CONNECT_DATA=(SID=$sid)))";
$conn-&gt;Connect($cstr, 'scott', 'tiger');
</pre>
<p>f. ADOdb data source names (dsn):
<pre>
$dsn = 'oci8://user:pwd@tnsname/?persist'; # persist is optional
$conn = ADONewConnection($dsn); # no need for Connect/PConnect
$dsn = 'oci8://user:pwd@host/sid';
$conn = ADONewConnection($dsn);
$dsn = 'oci8://user:pwd@/'; # oracle on local machine
$conn = ADONewConnection($dsn);</pre>
<p>With ADOdb data source names,
you don't have to call Connect( ) or PConnect( ).
</p>
<p>&nbsp;</p>
<h3>10. Error Checking</h3>
<p>The examples in this article are easy to read but a bit simplistic because we ignore error-handling. Execute( ) and Connect( ) will return false on error. So a more realistic way to call Connect( ) and Execute( ) is:
<pre>function InvokeErrorHandler()
{<br>global $db; ## assume global
MyLogFunction($db-&gt;ErrorNo(), $db-&gt;ErrorMsg());
}
if (!$db-&gt;Connect($tns, $usr, $pwd)) InvokeErrorHandler();
$rs = $db->Execute("select * from emp where empno>:emp order by empno",
array('emp' => 7900));
if (!$rs) return InvokeErrorHandler();
while ($arr = $rs->FetchRow()) {
print_r($arr);
echo "&lt;hr>";
}
</pre>
<p>You can retrieve the error message and error number of the last SQL statement executed from ErrorMsg( ) and ErrorNo( ). You can also <a href=http://phplens.com/adodb/using.custom.error.handlers.and.pear_error.html>define a custom error handler function</a>.
ADOdb also supports throwing exceptions in PHP5.
<p>&nbsp;</p>
<h3>Handling Large Recordsets (added 27 May 2005)</h3>
The oci8 driver does not support counting the number of records returned in a SELECT statement, so the function RecordCount()
is emulated when the global variable $ADODB_COUNTRECS is set to true, which is the default.
We emulate this by buffering all the records. This can take up large amounts of memory for big recordsets.
Set $ADODB_COUNTRECS to false for the best performance.
<p>
This variable is checked every time a query is executed, so you can selectively choose which recordsets to count.
<p>&nbsp;</p>
<h3>11. Other ADOdb Features</h3>
<p><a href="http://phplens.com/lens/adodb/docs-datadict.htm">Schema generation</a>. This allows you to define a schema using XML and import it into different RDBMS systems portably.</p>
<p><a href="http://phplens.com/lens/adodb/docs-perf.htm">Performance monitoring and tracing</a>. Highlights of performance monitoring include identification of poor and suspicious SQL, with explain plan support, and identifying which web pages the SQL ran on.</p>

<h3>The ADOdb Performance Monitoring Library</h3>
<p>V5.06 16 Oct 2008 (c) 2000-2010 John Lim (jlim#natsoft.com)</p>
<p><font size="1">This software is dual licensed using BSD-Style and
LGPL. This means you can use it in compiled proprietary and commercial
products.</font></p>

</p>
<h3>Introduction</h3>
<p>This module, part of the ADOdb package, provides both CLI and HTML
interfaces for viewing key performance indicators of your database.
This is very useful because web apps such as the popular phpMyAdmin
currently do not provide effective database health monitoring tools.
The module provides the following: </p>
<ul>
<li>A quick health check of your database server using <code>$perf-&gt;HealthCheck()</code>
or <code>$perf-&gt;HealthCheckCLI()</code>. </li>
<li>User interface for performance monitoring, <code>$perf-&gt;UI()</code>.
This UI displays:
<ul>
<li>the health check, </li>
<li>all SQL logged and their query plans, </li>
<li>a list of all tables in the current database</li>
<li>an interface to continiously poll the server for key
performance indicators such as CPU, Hit Ratio, Disk I/O</li>
<li>a form where you can enter and run SQL interactively.</li>
</ul>
</li>
<li>Gives you an API to build database monitoring tools for a server
farm, for example calling <code>$perf-&gt;DBParameter('data cache hit
ratio')</code> returns this very important statistic in a database
independant manner. </li>
</ul>
<p>ADOdb also has the ability to log all SQL executed, using <a
href="docs-adodb.htm#logsql">LogSQL</a>. All SQL logged can be
analyzed through the performance monitor <a href="#ui">UI</a>. In the <i>View
SQL</i> mode, we categorize the SQL into 3 types:
</p>
<ul>
<li><b>Suspicious SQL</b>: queries with high average execution times,
and are potential candidates for rewriting</li>
<li><b>Expensive SQL</b>: queries with high total execution times
(#executions * avg execution time). Optimizing these queries will
reduce your database server load.</li>
<li><b>Invalid SQL</b>: queries that generate errors.</li>
</ul>
<p>Each query is hyperlinked to a description of the query plan, and
every PHP script that executed that query is also shown.</p>
<p>Please note that the information presented is a very basic database
health check, and does not provide a complete overview of database
performance. Although some attempt has been made to make it work across
multiple databases in the same way, it is impossible to do so. For the
health check, we do try to display the following key database
parameters for all drivers:</p>
<ul>
<li><b>data cache size</b> - The amount of memory allocated to the
cache.</li>
<li><b>data cache hit ratio</b> - A measure of how effective the
cache is, as a percentage. The higher, the better.</li>
<li><b>current connections</b> - The number of sessions currently
connected to the database. </li>
</ul>
<p>You will need to connect to the database as an administrator to view
most of the parameters. </p>
<p>Code improvements as very welcome, particularly adding new database
parameters and automated tuning hints.</p>
<a name="usage"></a>
<h3>Usage</h3>
<p>Currently, the following drivers: <em>mysql</em>, <em>postgres</em>,
<em>oci8</em>, <em>mssql</em>, <i>informix</i> and <em>db2</em> are
supported. To create a new performance monitor, call NewPerfMonitor( )
as demonstrated below: </p>
<pre>&lt;?php<br>include_once('adodb.inc.php');<br>session_start(); <font
color="#006600"># session variables required for monitoring</font><br>$conn = ADONewConnection($driver);<br>$conn-&gt;Connect($server,$user,$pwd,$db);<br>$perf =&amp; NewPerfMonitor($conn);<br>$perf-&gt;UI($pollsecs=5);<br>?&gt;<br></pre>
<p>It is also possible to retrieve a single database parameter:</p>
<pre>$size = $perf-&gt;DBParameter('data cache size');<br></pre>
<p>
Thx to Fernando Ortiz for the informix module. </p>
<h3>Methods</h3>
<a name="ui"></a>
<p><font face="Courier New, Courier, mono">function <b>UI($pollsecs=5)</b></font></p>
<p>Creates a web-based user interface for performance monitoring. When
you click on Poll, server statistics will be displayed every $pollsecs
seconds. See <a href="#usage">Usage</a> above. </p>
<p>Since 4.11, we allow users to enter and run SQL interactively via
the "Run SQL" link. To disable this for security reasons, set this
constant before calling $perf-&gt;UI(). </p>

<p><b>WS-CPU%</b> is the Web Server CPU load of the server that PHP is
running from (eg. the database client), and not the database. The <b>Hit%</b>
is the data cache hit ratio. <b>Sess</b> is the current number of
sessions connected to the database. If you are using persistent
connections, this should not change much. The <b>Reads/s</b> and <b>Writes/s</b>
are synthetic values to give the viewer a rough guide to I/O, and are
not to be taken literally. </p>
<p><font face="Courier New, Courier, mono">function <b>SuspiciousSQL</b>($numsql=10)</font></p>
<p>Returns SQL which have high average execution times as a HTML table.
Each sql statement
is hyperlinked to a new window which details the execution plan and the
scripts that execute this SQL.
</p>
<p> The number of statements returned is determined by $numsql. Data is
taken from the adodb_logsql table, where the sql statements are logged
when
$connection-&gt;LogSQL(true) is enabled. The adodb_logsql table is
populated using <a href="docs-adodb.htm#logsql">$conn-&gt;LogSQL</a>.
</p>
<p>For Oracle, Ixora Suspicious SQL returns a list of SQL statements
that are most cache intensive as a HTML table. These are data intensive
SQL statements that could benefit most from tuning. </p>
<p><font face="Courier New, Courier, mono">function <b>ExpensiveSQL</b>($numsql=10)</font></p>
<p>Returns SQL whose total execution time (avg time * #executions) is
high as a HTML table. Each sql statement
is hyperlinked to a new window which details the execution plan and the
scripts that execute this SQL.
</p>
<p> The number of statements returned is determined by $numsql. Data is
taken from the adodb_logsql table, where the sql statements are logged
when
$connection-&gt;LogSQL(true) is enabled. The adodb_logsql table is
populated using <a href="docs-adodb.htm#logsql">$conn-&gt;LogSQL</a>.
</p>
<p>For Oracle, Ixora Expensive SQL returns a list of SQL statements
that are taking the most CPU load when run.
</p>
<p><font face="Courier New, Courier, mono">function <b>InvalidSQL</b>($numsql=10)</font></p>
<p>Returns a list of invalid SQL as an HTML table.
</p>
<p>Data is taken from the adodb_logsql table, where the sql statements
are logged when
$connection-&gt;LogSQL(true) is enabled.
</p>
<p><font face="Courier New, Courier, mono">function <b>Tables</b>($orderby=1)</font></p>
<p>Returns information on all tables in a database, with the first two
fields containing the table name and table size, the remaining fields
depend on the database driver. If $orderby is set to 1, it will sort by
name. If $orderby is set to 2, then it will sort by table size. Some
database drivers (mssql and mysql) will ignore the $orderby clause. For
postgresql, the information is up-to-date since the last <i>vacuum</i>.
Not supported currently for db2.</p>
<h3>Raw Functions</h3>
<p>Raw functions return values without any formatting.</p>
<p><font face="Courier New, Courier, mono">function <b>DBParameter</b>($paramname)</font></p>
<p>Returns the value of a database parameter, such as
$this-&gt;DBParameter("data cache size").</p>
<p><font face="Courier New, Courier, mono">function <b>CPULoad</b>()</font></p>
<p>Returns the CPU load of the database client (NOT THE SERVER) as a
percentage. Only works for Linux and Windows. For Windows, WMI must be
available.</p>
<h3>$ADODB_PERF_MIN</h3>
<p>New in adodb 4.97/5.03 is this global variable, which controls whether sql timings which are too small are not saved. Currently it defaults
to 0.05 (seconds). This means that all sql's which are faster than 0.05 seconds to execute are not saved.
<h3>Format of $settings Property</h3>
<p> To create new database parameters, you need to understand
$settings. The $settings data structure is an associative array. Each
element of the array defines a database parameter. The key is the name
of the database parameter. If no key is defined, then it is assumed to
be a section break, and the value is the name of the section break. If
this is too confusing, looking at the source code will help a lot!</p>
<p> Each database parameter is itself an array consisting of the
following elements:</p>
<ol start="0">
<li> Category code, used to group related db parameters. If the
category code is 'HIDE', then
the database parameter is not shown when HTML() is called. <br>
</li>
<li> either
<ol type="a">
<li>sql string to retrieve value, eg. "select value from
v\$parameter where name='db_block_size'", </li>
<li>array holding sql string and field to look for, e.g.
array('show variables','table_cache'); optional 3rd parameter is the
$rs-&gt;fields[$index] to use (otherwise $index=1), and optional 4th
parameter is a constant to multiply the result with (typically 100 for
percentage calculations),</li>
<li>a string prefixed by =, then a PHP method of the class is
invoked, e.g. to invoke $this-&gt;GetIndexValue(), set this array
element to '=GetIndexValue', <br>
</li>
</ol>
</li>
<li> Description of database parameter. If description begins with an
=, then it is interpreted as a method call, just as in (1c) above,
taking one parameter, the current value. E.g. '=GetIndexDescription'
will invoke $this-&gt;GetIndexDescription($val). This is useful for
generating tuning suggestions. For an example, see WarnCacheRatio().</li>
</ol>
<p>Example from MySQL, table_cache database parameter:</p>
<pre>'table cache' =gt; array('CACHE', # category code<br> array("show variables", 'table_cache'), # array (type 1b)<br> 'Number of tables to keep open'), # description</pre>

<h2>Introduction</h2>
<p> This document discusses the newer session handler adodb-session2.php. If
you have used the older adodb-session.php, then be forewarned that you will
need to alter your session table format. Otherwise everything is <a href="#compat">backward
compatible</a>.
Here are the <a href="docs-session.old.htm">older
docs</a> for
adodb-session.php.</p>
<h2>Why Session Variables in a Database? </h2>
<p>We store state information specific to a user or web
client in session variables. These session variables persist throughout a
session, as the user moves from page to page. </p>
<p>To use session variables, call session_start() at the beginning of
your web page, before your HTTP headers are sent. Then for every
variable you want to keep alive for the duration of the session, call
session_register($variable_name). By default, the session handler will
keep track of the session by using a cookie. You can save objects or
arrays in session variables also.
</p>
<p>The default method of storing sessions is to store it in a file.
However if you have special needs such as you:
</p>
<ul>
<li>Have multiple web servers that need to share session info</li>
<li>Need to do special processing of each session</li>
<li>Require notification when a session expires</li>
</ul>
<p>The ADOdb session handler provides you with the above
additional capabilities by storing the session information as records
in a database table that can be shared across multiple servers. </p>
<p>These records will be garbage collected based on the php.ini [session] timeout settings.
You can register a notification function to notify you when the record has expired and
is about to be freed by the garbage collector.</p>
<p>An alternative to using a database backed session handler is to use <a href="http://www.danga.com/memcached/">memcached</a>.
This is a distributed memory based caching system suitable for storing session
information.
</p>
<h2> The Improved Session Handler</h2>
<p>In ADOdb 4.91, we added a new session handler, in adodb-session2.php.
It features the following improvements:
<ul>
<li>Fully supports server farms using a new database table format. The
previous version used the web server time for timestamps, which can cause problems
on a system with multiple web servers with possibly inconsistent
times. The new version uses the database server time instead for all timestamps.
<li>The older database table format is obsolete. The database table must be modified
to support storage of the database server time mentioned above. Also the field
named DATA has been changed to SESSDATA. In some databases, DATA is a reserved
word.
<li>The functions dataFieldName() and syncSeconds() is obsolete.
</ul>
<p>Usage is
<pre>
include_once("adodb/session/adodb-session2.php");
ADOdb_Session::config($driver, $host, $user, $password, $database,$options=false);
session_start();
<font
color="#004040">#<br># Test session vars, the following should increment on refresh<br>#<br>$_SESSION['AVAR'] += 1;<br>print "&lt;p&gt;\$_SESSION['AVAR']={$_SESSION['AVAR']}&lt;/p&gt;";</font>
</pre>
<p>When the session is created in session_start( ), the global variable $<b>ADODB_SESS_CONN</b> holds
the connection object.
<p>The default name of the table is sessions2. If you want to override it:
<pre>
include_once("adodb/session/adodb-session2.php");
$options['table'] = 'mytablename';
ADOdb_Session::config($driver, $host, $user, $password, $database,$options);
session_start();
</pre>
<h3>ADOdb Session Handler Features</h3>
<ul>
<li>Ability to define a notification function that is called when a
session expires. Typically
used to detect session logout and release global resources. </li>
<li>Optimization of database writes. We crc32 the session data and
only perform an update
to the session data if there is a data change. </li>
<li>Support for large amounts of session data with CLOBs (see
adodb-session-clob2.php). Useful
for Oracle. </li>
<li>Support for encrypted session data, see
adodb-cryptsession2.php. Enabling encryption is simply a matter of
including adodb-cryptsession2.php instead of adodb-session2.php. </li>
</ul>
<h3>Session Handler Files </h3>
<p>There are 3 session management files that you can use:
</p>
<pre>adodb-session2.php : The default<br>adodb-cryptsession2.php : Use this if you want to store encrypted session data in the database<br>adodb-session-clob2.php : Use this if you are storing DATA in clobs and you are NOT using oci8 driver</pre>
<h2><strong>Usage Examples</strong></h2>
<p>To force non-persistent connections, call <font color="#004040"><b>Persist</b></font>() first before session_start():
<pre>
<font color="#004040">
include_once("adodb/session/adodb-session2.php");
$driver = 'mysql'; $host = 'localhost'; $user = 'auser'; $pwd = 'secret'; $database = 'sessiondb';
ADOdb_Session::config($driver, $host, $user, $password, $database, $options=false);<b><br>ADOdb_session::Persist($connectMode=false);</b>
session_start();<br>
# or, using DSN support so you can set other options such as port (since 5.11)
include_once("adodb/session/adodb-session2.php");
$dsn = 'mysql://root:pwd@localhost/mydb?persist=1&port=5654';
ADOdb_Session::config($dsn, '', '', '');
session_start();
</font></pre>
<p> The parameter to the Persist( ) method sets the connection mode. You can
pass the following:</p>
<table width="50%" border="1">
<tr>
<td><b>$connectMode</b></td>
<td><b>Connection Method</b></td>
</tr>
<tr>
<td>true</td>
<td><p>PConnect( )</p></td>
</tr>
<tr>
<td>false</td>
<td>Connect( )</td>
</tr>
<tr>
<td>'N'</td>
<td>NConnect( )</td>
</tr>
<tr>
<td>'P'</td>
<td>PConnect( )</td>
</tr>
<tr>
<td>'C'</td>
<td>Connect( )</td>
</tr>
</table>
<p>To use a encrypted sessions, simply replace the file adodb-session2.php:</p>
<pre> <font
color="#004040"><b><br>include('adodb/session/adodb-cryptsession2.php');</b><br>$driver = 'mysql'; $host = 'localhost'; $user = 'auser'; $pwd = 'secret'; $database = 'sessiondb';
ADOdb_Session::config($driver, $host, $user, $password, $database,$options=false);<b><br>adodb_sess_open(false,false,$connectMode=false);</b>
session_start();<br></font></pre>
<p>And the same technique for adodb-session-clob2.php:</p>
<pre> <font
color="#004040"><br><b>include('adodb/session/adodb-session2-clob2.php');</b><br>$driver = 'oci8'; $host = 'localhost'; $user = 'auser'; $pwd = 'secret'; $database = 'sessiondb';
ADOdb_Session::config($driver, $host, $user, $password, $database,$options=false);<b><br>adodb_sess_open(false,false,$connectMode=false);</b>
session_start();</font></pre>
<h2>Installation</h2>
<p>1. Create this table in your database. Here is the MySQL version:
<pre> <a
name="sessiontab"></a> <font color="#004040">
CREATE TABLE sessions2(
sesskey VARCHAR( 64 ) NOT NULL DEFAULT '',
expiry DATETIME NOT NULL ,
expireref VARCHAR( 250 ) DEFAULT '',
created DATETIME NOT NULL ,
modified DATETIME NOT NULL ,
sessdata LONGTEXT,
PRIMARY KEY ( sesskey ) ,
INDEX sess2_expiry( expiry ),
INDEX sess2_expireref( expireref )
)</font></pre>
<p> For PostgreSQL, use:
<pre>CREATE TABLE sessions2(
sesskey VARCHAR( 64 ) NOT NULL DEFAULT '',
expiry TIMESTAMP NOT NULL ,
expireref VARCHAR( 250 ) DEFAULT '',
created TIMESTAMP NOT NULL ,
modified TIMESTAMP NOT NULL ,
sessdata TEXT DEFAULT '',
PRIMARY KEY ( sesskey )
);
</pre>
<pre>create INDEX sess2_expiry on sessions2( expiry );
create INDEX sess2_expireref on sessions2 ( expireref );</pre>
<p>Here is the Oracle definition, which uses a CLOB for the SESSDATA field:
<pre>
<font
color="#004040">CREATE TABLE SESSIONS2<br>(<br> SESSKEY VARCHAR2(48 BYTE) NOT NULL,<br> EXPIRY DATE NOT NULL,<br> EXPIREREF VARCHAR2(200 BYTE),<br> CREATED DATE NOT NULL,<br> MODIFIED DATE NOT NULL,<br> SESSDATA CLOB,<br> PRIMARY KEY(SESSKEY)<br>);
<br>CREATE INDEX SESS2_EXPIRY ON SESSIONS2(EXPIRY);
CREATE INDEX SESS2_EXPIREREF ON SESSIONS2(EXPIREREF);</font></pre>
<p> We need to use a CLOB here because for text greater than 4000 bytes long,
Oracle requires you to use the CLOB data type. If you are using the oci8 driver,
ADOdb will automatically enable CLOB handling. So you can use either adodb-session2.php
or adodb-session-clob2.php - in this case it doesn't matter. <br>
<h2>Notifications</h2>
<p>You can receive notification when your session is cleaned up by the session garbage collector or
when you call session_destroy().
<p>PHP's session extension will automatically run a special garbage collection function based on
your php.ini session.cookie_lifetime and session.gc_probability settings. This will in turn call
adodb's garbage collection function, which can be setup to do notification.
<p>
<pre>
PHP Session --> ADOdb Session --> Find all recs --> Send --> Delete queued
GC Function GC Function to be deleted notification records
executed at called by for all recs
random time Session Extension queued for deletion
</pre>
<p>When a session is created, we need to store a value in the session record (in the EXPIREREF field), typically
the userid of the session. Later when the session has expired, just before the record is deleted,
we reload the EXPIREREF field and call the notification function with the value of EXPIREREF, which
is the userid of the person being logged off.
<p>ADOdb uses a global variable $ADODB_SESSION_EXPIRE_NOTIFY that you must predefine before session
start to store the notification configuration.
$ADODB_SESSION_EXPIRE_NOTIFY is an array with 2 elements, the
first being the name of the session variable you would like to store in
the EXPIREREF field, and the 2nd is the notification function's name. </p>
<p>For example, suppose we want to be notified when a user's session has expired,
based on the userid. When the user logs in, we store the id in the global session variable
$USERID. The function name is 'NotifyFn'.
<p>
So we define (before session_start() is called): </p>
<pre> <font color="#004040">
$ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');
</font></pre>
And when the NotifyFn is called (when the session expires), the
$EXPIREREF holding the user id is passed in as the first parameter, eg. NotifyFn($userid, $sesskey). The
session key (which is the primary key of the record in the sessions
table) is the 2nd parameter.
<p> Here is an example of a Notification function that deletes some
records in the database and temporary files: </p>
<pre><font color="#004040">
function NotifyFn($expireref, $sesskey)
{
global $ADODB_SESS_CONN; # the session connection object
$user = $ADODB_SESS_CONN-&gt;qstr($expireref);
$ADODB_SESS_CONN-&gt;Execute("delete from shopping_cart where user=$user");
system("rm /work/tmpfiles/$expireref/*");
}</font>
</pre>
<p> NOTE 1: If you have register_globals disabled in php.ini, then you
will have to manually set the EXPIREREF. E.g. </p>
<pre> <font color="#004040">
$GLOBALS['USERID'] = GetUserID();
$ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');</font>
</pre>
<p> NOTE 2: If you want to change the EXPIREREF after the session
record has been created, you will need to modify any session variable
to force a database record update.
</p>
<h3>Neat Notification Tricks</h3>
<p><i>ExpireRef</i> normally holds the user id of the current session.
</p>
<p>1. You can then write a session monitor, scanning expireref to see
who is currently logged on.
</p>
<p>2. If you delete the sessions record for a specific user, eg.
</p>
<pre>delete from sessions where expireref = '$USER'<br></pre>
then the user is logged out. Useful for ejecting someone from a
site.
<p>3. You can scan the sessions table to ensure no user
can be logged in twice. Useful for security reasons.
</p>
<h2>Compression/Encryption Schemes</h2>
Since ADOdb 4.05, thanks to Ross Smith, multiple encryption and
compression schemes are supported. Currently, supported are:
<p>
<pre> MD5Crypt (crypt.inc.php)<br> MCrypt<br> Secure (Horde's emulation of MCrypt, if MCrypt module is not available.)<br> GZip<br> BZip2<br></pre>
<p>These are stackable. E.g.
<pre>ADODB_Session::filter(new ADODB_Compress_Bzip2());<br>ADODB_Session::filter(new ADODB_Encrypt_MD5());<br></pre>
will compress and then encrypt the record in the database.
<h2>Session Cookie Regeneration: adodb_session_regenerate_id()</h2>
<p>Dynamically change the current session id with a newly generated one and update
database. Currently only works with cookies. Useful to improve security by
reducing the risk of session-hijacking. See this article on <a href=http://shiflett.org/articles/security-corner-feb2004>Session
Fixation</a> for more info
on the theory behind this feature. Usage:<pre>
include('path/to/adodb/session/adodb-session2.php');
session_start();
# Approximately every 10 page loads, reset cookie for safety.
# This is extremely simplistic example, better
# to regenerate only when the user logs in or changes
# user privilege levels.
if ((rand()%10) == 0) adodb_session_regenerate_id();
</pre>
<p>This function calls session_regenerate_id() internally or simulates it if the function does not exist.
<h2>Vacuum/Optimize Database</h2>
<p>During session garbage collection, if postgresql is detected,
ADOdb can be set to run VACUUM. If mysql is detected, then optimize database
could be called.You can turn this on or off using:</p>
<pre>$turnOn = true; # or false
ADODB_Session::optimize($turnOn);
</pre>
<p>The default is optimization is disabled.</p>
<h2><a name=compat></a>Backwards Compatability </h2>
<p>The older method of connecting to ADOdb using global variables is still supported:</p>
<pre> $ADODB_SESSION_DRIVER='mysql';
$ADODB_SESSION_CONNECT='localhost';
$ADODB_SESSION_USER ='root';
$ADODB_SESSION_PWD ='abc';
$ADODB_SESSION_DB ='phplens';
include('path/to/adodb/session/adodb-<strong>session2</strong>.php'); </pre>
<p>In the above example, the only things you need to change in your code to upgrade
is </p>
<ul>
<li>your session table format to the new one.</li>
<li>the include file from adodb-session.php to adodb-session2.php. </li>
</ul>

<h3>Introduction</h3>
<p>This documentation discusses the old adodb-session.php.
Here is the <a href=docs-session.htm>new documentation</a> on the newer adodb-session2.php.
<p> We store state information specific to a user or web client in
session variables. These session variables persist throughout a
session, as the user moves from page to page. </p>
<p>To use session variables, call session_start() at the beginning of
your web page, before your HTTP headers are sent. Then for every
variable you want to keep alive for the duration of the session, call
session_register($variable_name). By default, the session handler will
keep track of the session by using a cookie. You can save objects or
arrays in session variables also.
</p>
<p>The default method of storing sessions is to store it in a file.
However if you have special needs such as you:
</p>
<ul>
<li>Have multiple web servers that need to share session info</li>
<li>Need to do special processing of each session</li>
<li>Require notification when a session expires</li>
</ul>
<p>The ADOdb session handler provides you with the above
additional capabilities by storing the session information as records
in a database table that can be shared across multiple servers. </p>
<p>These records will be garbage collected based on the php.ini [session] timeout settings.
You can register a notification function to notify you when the record has expired and
is about to be freed by the garbage collector.</p>
<p><b>Important Upgrade Notice:</b> Since ADOdb 4.05, the session files
have been moved to its own folder, adodb/session. This is a rewrite
of the session code by Ross Smith. The old session code is in
adodb/session/old. </p>
<h4>ADOdb Session Handler Features</h4>
<ul>
<li>Ability to define a notification function that is called when a
session expires. Typically
used to detect session logout and release global resources. </li>
<li>Optimization of database writes. We crc32 the session data and

<li>Support for encrypted session data, see

</ul>
<h3>Setup</h3>
<p>There are 3 session management files that you can use:
</p>
<pre>adodb-session.php : The default<br>adodb-session-clob.php : Use this if you are storing DATA in clobs<br>adodb-cryptsession.php : Use this if you want to store encrypted session data in the database<br><br>
</pre>
<p><strong>Examples</strong>
<p><pre>
<font
color="#004040"> include('adodb/adodb.inc.php');<br> <br><b> $ADODB_SESSION_DRIVER='mysql';<br> $ADODB_SESSION_CONNECT='localhost';<br> $ADODB_SESSION_USER ='scott';<br> $ADODB_SESSION_PWD ='tiger';<br> $ADODB_SESSION_DB ='sessiondb';</b><br> <br> <b>include('adodb/session/adodb-session.php');</b><br> session_start();<br> <br> #<br> # Test session vars, the following should increment on refresh<br> #<br> $_SESSION['AVAR'] += 1;<br> print "&lt;p&gt;\$_SESSION['AVAR']={$_SESSION['AVAR']}&lt;/p&gt;";<br></font></pre>
<p>To force non-persistent connections, call adodb_session_open() first before session_start():
<p>
<pre>
<font color="#004040"><br> include('adodb/adodb.inc.php');<br> <br><b> $ADODB_SESSION_DRIVER='mysql';<br> $ADODB_SESSION_CONNECT='localhost';<br> $ADODB_SESSION_USER ='scott';<br> $ADODB_SESSION_PWD ='tiger';<br> $ADODB_SESSION_DB ='sessiondb';</b><br> <br> <b>include('adodb/session/adodb-session.php');<br> adodb_sess_open(false,false,false);</b><br> session_start();<br> </font>
</pre>
<p> The 3rd parameter to adodb_sess_open($path, $sessname, $connectMode) sets the connection method. You can pass in the following:</p>
<table width="50%" border="1">
<tr>
<td><b>$connectMode</b></td>
<td><b>Connection Method</b></td>
</tr>
<tr>
<td>true</td>
<td><p>PConnect( )</p></td>
</tr>
<tr>
<td>false</td>
<td>Connect( )</td>
</tr>
<tr>
<td>'N'</td>
<td>NConnect( )</td>
</tr>
<tr>
<td>'P'</td>
<td>PConnect( )</td>
</tr>
<tr>
<td>'C'</td>
<td>Connect( )</td>
</tr>
</table>
<p>To use a encrypted sessions, simply replace the file adodb-session.php:</p>
<pre> <font
color="#004040"><br> include('adodb/adodb.inc.php');<br> <br><b> $ADODB_SESSION_DRIVER='mysql';<br> $ADODB_SESSION_CONNECT='localhost';<br> $ADODB_SESSION_USER ='scott';<br> $ADODB_SESSION_PWD ='tiger';<br> $ADODB_SESSION_DB ='sessiondb';<br> <br> include('adodb/session/adodb-cryptsession.php');</b><br> session_start();</font><br>
</pre>
<p>And the same technique for adodb-session-clob.php:</p>
<pre> <font
color="#004040"><br> include('adodb/adodb.inc.php');<br> <br><b> $ADODB_SESSION_DRIVER='mysql';<br> $ADODB_SESSION_CONNECT='localhost';<br> $ADODB_SESSION_USER ='scott';<br> $ADODB_SESSION_PWD ='tiger';<br> $ADODB_SESSION_DB ='sessiondb';<br> <br> include('adodb/session/adodb-session-clob.php');</b><br> session_start();</font>
</pre>
<p>An alternative way to set persistant or non-persistent connections is to call the following function before session_start() is called.
<pre>
ADODB_Session::persist('P'); # 'C' for non-persistent connections
</pre>
<h4>Installation</h4>
<p>1. Create this table in your database (MySQL syntax):
<p><pre> <a
name="sessiontab"></a> <font color="#004040">
create table sessions (
SESSKEY char(32) not null,
EXPIRY int(11) unsigned not null,
EXPIREREF varchar(64),
DATA text not null,
primary key (sesskey)
);</font>
</pre>
<p>You may want to rename the 'data' field to 'session_data' as
'data' appears to be a reserved word for one or more of the following:
<ul>
<li> ANSI SQL
<li> IBM DB2
<li> MS SQL Server
<li> Postgres
<li> SAP
</ul>
<p>
If you do, then execute:
<pre>
ADODB_Session::dataFieldName('session_data');
</pre>
<p> For the adodb-session-clob.php version, create this:
<p> <pre>
<font
color="#004040"><br> create table sessions (<br> SESSKEY char(32) not null,<br> EXPIRY int(11) unsigned not null,<br> EXPIREREF varchar(64),<br> DATA CLOB,<br> primary key (sesskey)<br> );</font>
</pre>
<p>2. Then define the following parameters. You can either modify this file, or define them before this file is included:
<pre> <font
color="#004040"><br> $ADODB_SESSION_DRIVER='database driver, eg. mysql or ibase';<br> $ADODB_SESSION_CONNECT='server to connect to';<br> $ADODB_SESSION_USER ='user';<br> $ADODB_SESSION_PWD ='password';<br> $ADODB_SESSION_DB ='database';<br> $ADODB_SESSION_TBL = 'sessions'; # setting this is optional<br> </font>
</pre><p>
When the session is created, $<b>ADODB_SESS_CONN</b> holds the connection object.<br> <br> 3. Recommended is PHP 4.0.6 or later. There are documented session bugs in earlier versions of PHP.
<h3>Notifications</h3>
<p>You can receive notification when your session is cleaned up by the session garbage collector or
when you call session_destroy().
<p>PHP's session extension will automatically run a special garbage collection function based on
your php.ini session.cookie_lifetime and session.gc_probability settings. This will in turn call
adodb's garbage collection function, which can be setup to do notification.
<p>
<pre>
PHP Session --> ADOdb Session --> Find all recs --> Send --> Delete queued
GC Function GC Function to be deleted notification records
executed at called by for all recs
random time Session Extension queued for deletion
</pre>
<p>When a session is created, we need to store a value in the session record (in the EXPIREREF field), typically
the userid of the session. Later when the session has expired, just before the record is deleted,
we reload the EXPIREREF field and call the notification function with the value of EXPIREREF, which
is the userid of the person being logged off.
<p>ADOdb uses a global variable $ADODB_SESSION_EXPIRE_NOTIFY that you must predefine before session
start to store the notification configuration.
$ADODB_SESSION_EXPIRE_NOTIFY is an array with 2 elements, the
first being the name of the session variable you would like to store in
the EXPIREREF field, and the 2nd is the notification function's name. </p>
<p>For example, suppose we want to be notified when a user's session has expired,
based on the userid. When the user logs in, we store the id in the global session variable
$USERID. The function name is 'NotifyFn'.
<p>
So we define (before session_start() is called): </p>
<pre> <font color="#004040">
$ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');
</font></pre>
And when the NotifyFn is called (when the session expires), the
$USERID is passed in as the first parameter, eg. NotifyFn($userid, $sesskey). The
session key (which is the primary key of the record in the sessions
table) is the 2nd parameter.
<p> Here is an example of a Notification function that deletes some
records in the database and temporary files: </p>
<pre><font color="#004040">
function NotifyFn($expireref, $sesskey)
{
global $ADODB_SESS_CONN; # the session connection object
$user = $ADODB_SESS_CONN-&gt;qstr($expireref);
$ADODB_SESS_CONN-&gt;Execute("delete from shopping_cart where user=$user");
system("rm /work/tmpfiles/$expireref/*");
}</font>
</pre>
<p> NOTE 1: If you have register_globals disabled in php.ini, then you
will have to manually set the EXPIREREF. E.g. </p>
<pre> <font color="#004040">
$GLOBALS['USERID'] = GetUserID();
$ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');</font>
</pre>
<p> NOTE 2: If you want to change the EXPIREREF after the session
record has been created, you will need to modify any session variable
to force a database record update.
</p>
<h4>Neat Notification Tricks</h4>
<p><i>ExpireRef</i> normally holds the user id of the current session.
</p>
<p>1. You can then write a session monitor, scanning expireref to see
who is currently logged on.
</p>
<p>2. If you delete the sessions record for a specific user, eg.
</p>
<pre>delete from sessions where expireref = '$USER'<br></pre>
then the user is logged out. Useful for ejecting someone from a
site.
<p>3. You can scan the sessions table to ensure no user
can be logged in twice. Useful for security reasons.
</p>
<h3>Using Oracle CLOBs</h3>
<p>Suppose you are storing the DATA field in a CLOB:
<pre><font color="#004040">
CREATE TABLE sessions (
SESSKEY VARCHAR(32) NOT NULL,
EXPIRY NUMBER(16) NOT NULL,
EXPIREREF VARCHAR(64),
DATA CLOB,
PRIMARY KEY (sesskey)
);</font>
</pre>
<p>Then your PHP code could look like this:
<pre>
ADODB_SESSION_DRIVER='oci8';
$ADODB_SESSION_CONNECT=$tnsname;
$ADODB_SESSION_USER ='scott';
$ADODB_SESSION_PWD = 'tiger';
$ADODB_SESSION_DB ='';
$ADODB_SESSION_USE_LOBS = 'clob';
$ADODB_SESSION_TBL = 'sessions';
$ADODB_SESS_DEBUG=0;
include(ADODB_DIR.'/session/adodb-session.php');
ADODB_Session::persist('P'); # use 'C' for non-persistent connects
session_start();
</pre>
<p>Note that you can set persistance using ADODB_Session::persist('P').
<h3>Compression/Encryption Schemes</h3>
Since ADOdb 4.05, thanks to Ross Smith, multiple encryption and
compression schemes are supported. Currently, supported are:
<p>
<pre> MD5Crypt (crypt.inc.php)<br> MCrypt<br> Secure (Horde's emulation of MCrypt, if MCrypt module is not available.)<br> GZip<br> BZip2<br></pre>
<p>These are stackable. E.g.
<p><pre>ADODB_Session::filter(new ADODB_Compress_Bzip2());<br>ADODB_Session::filter(new ADODB_Encrypt_MD5());<br></pre>
will compress and then encrypt the record in the database.
<h3>adodb_session_regenerate_id()</h3>
<p>Dynamically change the current session id with a newly generated one and update database. Currently only
works with cookies. Useful to improve security by reducing the risk of session-hijacking.
See this article on <a href=http://shiflett.org/articles/security-corner-feb2004>Session Fixation</a> for more info
on the theory behind this feature. Usage:
<pre>
$ADODB_SESSION_DRIVER='mysql';
$ADODB_SESSION_CONNECT='localhost';
$ADODB_SESSION_USER ='root';
$ADODB_SESSION_PWD ='abc';
$ADODB_SESSION_DB ='phplens';
include('path/to/adodb/session/adodb-session.php');
session_start();
# Every 10 page loads, reset cookie for safety.
# This is extremely simplistic example, better
# to regenerate only when the user logs in or changes
# user privilege levels.
if ((rand()%10) == 0) adodb_session_regenerate_id();
</pre>
<p>This function calls session_regenerate_id() internally or simulates it if the function does not exist.
<h3>Vacuum/Optimize Database</h3>
<p>During session garbage collection, if postgresql is detected,
ADOdb can be set to run VACUUM. If mysql is detected, then optimize database
could be called.You can turn this on or off using:</p>
<pre>$turnOn = true; # or false
ADODB_Session::optimize($turnOn);
</pre>
<p>The default for optimization is it is disabled.</p>

to SQL_CUR_USE_ODBC as the cursor mode, and lastAffectedRows and SelectLimit()
fixes.
</p><p>The odbc driver's FetchField() field names did not obey ADODB_ASSOC_CASE. Fixed.
</p><p>Some bugs in adodb_backtrace() fixed.
</p><p>Added "INT IDENTITY" type to adorecordset::MetaType() to support odbc_mssql

</p>
<p><b>3.50 19 May 2003</b></p>
<p>Fixed mssql compat with FreeTDS. FreeTDS does not implement mssql_fetch_assoc().
<p>Merged back connection and recordset code into adodb.inc.php.
<p>ADOdb sessions using oracle clobs contributed by achim.gosse#ddd.de. See adodb-session-clob.php.
<p>Added /s modifier to preg_match everywhere, which ensures that regex does not
stop at /n. Thx Pao-Hsi Huang.
<p>Fixed error in metacolumns() for mssql.
<p>Added time format support for SQLDate.
<p>Image => B added to metatype.
<p>MetaType now checks empty($this->blobSize) instead of empty($this).
<p>Datadict has beta support for informix, sybase (mapped to mssql), db2 and generic
(which is a fudge).
<p>BlobEncode for postgresql uses pg_escape_bytea, if available. Needed for compat
with 7.3.
<p>Added $ADODB_LANG, to support multiple languages in MetaErrorMsg().
<p>Datadict can now parse table definition as declarative text.
<p>For DataDict, oci8 autoincrement trigger missing semi-colon. Fixed.
<p>For DataDict, when REPLACE flag enabled, drop sequence in datadict for autoincrement
field in postgres and oci8.s
<p>Postgresql defaults to template1 database if no database defined in connect/pconnect.
<p>We now clear _resultid in postgresql if query fails.
<p><b>3.40 19 May 2003</b></p>
<p>Added insert_id for odbc_mssql.
<p>Modified postgresql UpdateBlobFile() because it did not work in safe mode.
<p>Now connection object is passed to raiseErrorFn as last parameter. Needed by
StartTrans().
<p>Added StartTrans() and CompleteTrans(). It is recommended that you do not modify
transOff, but use the above functions.
<p>oci8po now obeys ADODB_ASSOC_CASE settings.
<p>Added virtualized error codes, using PEAR DB equivalents. Requires you to manually
include adodb-error.inc.php yourself, with MetaError() and MetaErrorMsg($errno).
<p>GetRowAssoc for mysql and pgsql were flawed. Fix by Ross Smith.
<p>Added to datadict types I1, I2, I4 and I8. Changed datadict type 'T' to map
to timestamp instead of datetime for postgresql.
<p>Error handling in ExecuteSQLArray(), adodb-datadict.inc.php did not work.
<p>We now auto-quote postgresql connection parameters when building connection
string.
<p>Added session expiry notification.
<p>We now test with odbc mysql - made some changes to odbc recordset constructor.
<p>MetaColumns now special cases access and other databases for odbc.
<p><b>3.31 17 March 2003</b></p>
<p>Added row checking for _fetch in postgres.
<p>Added Interval type to MetaType for postgres.
<p>Remapped postgres driver to call postgres7 driver internally.
<p>Adorecordset_array::getarray() did not return array when nRows >= 0.
<p>Postgresql: at times, no error message returned by pg_result_error() but error
message returned in pg_last_error(). Recoded again.
<p>Interbase blob's now use chunking for updateblob.
<p>Move() did not set EOF correctly. Reported by Jorma T.
<p>We properly support mysql timestamp fields when we are creating mysql tables
using the data-dict interface.
<p>Table regex includes backticks character now.
<p><b>3.30 3 March 2003</b></p>
<p>Added $ADODB_EXTENSION and $ADODB_COMPAT_FETCH constant.
<p>Made blank1stItem configurable using syntax "value:text" in GetMenu/GetMenu2.
Thx to Gabriel Birke.
<p>Previously ADOdb differed from the Microsoft standard because it did not define
what to set $this->fields when EOF was reached. Now at EOF, ADOdb sets $this->fields
to false for all databases, which is consist with Microsoft's implementation.
Postgresql and mysql have always worked this way (in 3.11 and earlier). If you
are experiencing compatibility problems (and you are not using postgresql nor
mysql) on upgrading to 3.30, try setting the global variables $ADODB_COUNTRECS
= true (which is the default) and $ADODB_FETCH_COMPAT = true (this is a new
global variable).
<p>We now check both pg_result_error and pg_last_error as sometimes pg_result_error
does not display anything. Iman Mayes
<p> We no longer check for magic quotes gpc in Quote().
<p> Misc fixes for table creation in adodb-datadict.inc.php. Thx to iamsure.
<p> Time calculations use adodb_time library for all negative timestamps due to
problems in Red Hat 7.3 or later. Formerly, only did this for Windows.
<p> In mssqlpo, we now check if $sql in _query is a string before we change ||
to +. This is to support prepared stmts.
<p> Move() and MoveLast() internals changed to support to support EOF and $this->fields
change.
<p> Added ADODB_FETCH_BOTH support to mssql. Thx to Angel Fradejas afradejas#mediafusion.es
<p> We now check if link resource exists before we run mysql_escape_string in
qstr().
<p> Before we flock in csv code, we check that it is not a http url.
<p><b>3.20 17 Feb 2003</b></p>
<p>Added new Data Dictionary classes for creating tables and indexes. Warning
- this is very much alpha quality code. The API can still change. See adodb/tests/test-datadict.php
for more info.
<p>We now ignore $ADODB_COUNTRECS for mysql, because PHP truncates incomplete
recordsets when mysql_unbuffered_query() is called a second time.
<p>Now postgresql works correctly when $ADODB_COUNTRECS = false.
<p>Changed _adodb_getcount to properly support SELECT DISTINCT.
<p>Discovered that $ADODB_COUNTRECS=true has some problems with prepared queries
- suspect PHP bug.
<p>Now GetOne and GetRow run in $ADODB_COUNTRECS=false mode for better performance.
<p>Added support for mysql_real_escape_string() and pg_escape_string() in qstr().
<p>Added an intermediate variable for mysql _fetch() and MoveNext() to store fields,
to prevent overwriting field array with boolean when mysql_fetch_array() returns
false.
<p>Made arrays for getinsertsql and getupdatesql case-insensitive. Suggested by
Tim Uckun" tim#diligence.com
<p><b>3.11 11 Feb 2003</b></p>
<p>Added check for ADODB_NEVER_PERSIST constant in PConnect(). If defined, then
PConnect() will actually call non-persistent Connect().
<p>Modified interbase to properly work with Prepare().
<p>Added $this->ibase_timefmt to allow you to change the date and time format.
<p>Added support for $input_array parameter in CacheFlush().
<p>Added experimental support for dbx, which was then removed when i found that
it was slower than using native calls.
<p>Added MetaPrimaryKeys for mssql and ibase/firebird.
<p>Added new $trim parameter to GetCol and CacheGetCol
<p>Uses updated adodb-time.inc.php 0.06.
<p><b>3.10 27 Jan 2003</b>
<p>Added adodb_date(), adodb_getdate(), adodb_mktime() and adodb-time.inc.php.
<p>For interbase, added code to handle unlimited number of bind parameters. From
Daniel Hasan daniel#hasan.cl.
<p>Added BlobDecode and UpdateBlob for informix. Thx to Fernando Ortiz.
<p>Added constant ADODB_WINDOWS. If defined, means that running on Windows.
<p>Added constant ADODB_PHPVER which stores php version as a hex num. Removed
$ADODB_PHPVER variable.
<p>Felho Bacsi reported a minor white-space regular expression problem in GetInsertSQL.
<p>Modified ADO to use variant to store _affectedRows
<p>Changed ibase to use base class Replace(). Modified base class Replace() to
support ibase.
<p>Changed odbc to auto-detect when 0 records returned is wrong due to bad odbc
drivers.
<p>Changed mssql to use datetimeconvert ini setting only when 4.30 or later (does
not work in 4.23).
<p>ExecuteCursor($stmt, $cursorname, $params) now accepts a new $params array
of additional bind parameters -- William Lovaton walovaton#yahoo.com.mx.
<p>Added support for sybase_unbuffered_query if ADODB_COUNTRECS == false. Thx
to chuck may.
<p>Fixed FetchNextObj() bug. Thx to Jorma Tuomainen.
<p>We now use SCOPE_IDENTITY() instead of @@IDENTITY for mssql - thx to marchesini#eside.it
<p>Changed postgresql movenext logic to prevent illegal row number from being
passed to pg_fetch_array().
<p>Postgresql initrs bug found by "Bogdan RIPA" bripa#interakt.ro $f1 accidentally
named $f
<p><b>3.00 6 Jan 2003</b>
<p>Fixed adodb-pear.inc.php syntax error.
<p>Improved _adodb_getcount() to use SELECT COUNT(*) FROM ($sql) for languages
that accept it.
<p>Fixed _adodb_getcount() caching error.
<p>Added sql to retrive table and column info for odbc_mssql.
<p><strong>2.91 3 Jan 2003</strong>
<p>Revised PHP version checking to use $ADODB_PHPVER with legal values 0x4000,
0x4050, 0x4200, 0x4300.
<p>Added support for bytea fields and oid blobs in postgres by allowing BlobDecode()
to detect and convert non-oid fields. Also added BlobEncode to postgres when
you want to encode oid blobs.
<p>Added blobEncodeType property for connections to inform phpLens what encoding
method to use for blobs.
<p>Added BlobDecode() and BlobEncode() to base ADOConnection class.
<p>Added umask() to _gencachename() when creating directories.
<p>Added charPage for ado drivers, so you can set the code page.
<pre>
$conn->charPage = CP_UTF8;
$conn->Connect($dsn);
</pre>
<p>Modified _seek in mysql to check for num rows=0.
<p>Added to metatypes new informix types for IDS 9.30. Thx Fernando Ortiz.
<p>_maxrecordcount returned in CachePageExecute $rsreturn

<p>MetaColumns() max_length should use precision for types X and C for ms access.
Fixed.
<p>Speedup of odbc non-SELECT sql statements.
<p>Added support in MetaColumns for Wide Char types for ODBC. We halve max_length
if unicode/wide char.
<p>Added 'B' to types handled by GetUpdateSQL/GetInsertSQL.
<p>Fixed warning message in oci8 driver with $persist variable when using PConnect.
<p><b>2.90 11 Dec 2002</b>
<p>Mssql and mssqlpo and oci8po now support ADODB_ASSOC_CASE.
<p>Now MetaType() can accept a field object as the first parameter.
<p>New $arr = $db-&gt;ServerInfo( ) function. Returns $arr['description'] which
is the string description, and $arr['version'].
<p>PostgreSQL and MSSQL speedups for insert/updates.
<p> Implemented new SetFetchMode() that removes the need to use $ADODB_FETCH_MODE.
Each connection has independant fetchMode.
<p>ADODB_ASSOC_CASE now defaults to 2, use native defaults. This is because we
would break backward compat for too many applications otherwise.
<p>Patched encrypted sessions to use replace()
<p>The qstr function supports quoting of nulls when escape character is \
<p>Rewrote bits and pieces of session code to check for time synch and improve
reliability.
<p>Added property ADOConnection::hasTransactions = true/false;
<p>Added CreateSequence and DropSequence functions
<p>Found misplaced MoveNext() in adodb-postgres.inc.php. Fixed.
<p>Sybase SelectLimit not reliable because 'set rowcount' not cached - fixed.
<p>Moved ADOConnection to adodb-connection.inc.php and ADORecordSet to adodb-recordset.inc.php.
This allows us to use doxygen to generate documentation. Doxygen doesn't like
the classes in the main adodb.inc.php file for some mysterious reason.
<p><b>2.50, 14 Nov 2002</b>
<p>Added transOff and transCnt properties for disabling (transOff = true) and
tracking transaction status (transCnt>0).
<p>Added inputarray handling into _adodb_pageexecute_all_rows - "Ross Smith" RossSmith#bnw.com.
<p>Fixed postgresql inconsistencies in date handling.
<p>Added support for mssql_fetch_assoc.
<p>Fixed $ADODB_FETCH_MODE bug in odbc MetaTables() and MetaPrimaryKeys().
<p>Accidentally declared UnixDate() twice, making adodb incompatible with php
4.3.0. Fixed.
<p>Fixed pager problems with some databases that returned -1 for _currentRow on
MoveLast() by switching to MoveNext() in adodb-lib.inc.php.
<p>Also fixed uninited $discard in adodb-lib.inc.php.
<p><b>2.43, 25 Oct 2002</b></p>
Added ADODB_ASSOC_CASE constant to better support ibase and odbc field names.
<p>Added support for NConnect() for oracle OCINLogin.
<p>Fixed NumCols() bug.
<p>Changed session handler to use Replace() on write.
<p>Fixed oci8 SelectLimit aggregate function bug again.
<p>Rewrote pivoting code.
<p><b>2.42, 4 Oct 2002</b></p>
<p>Fixed ibase_fetch() problem with nulls. Also interbase now does automatic blob
decoding, and is backward compatible. Suggested by Heinz Hombergs heinz#hhombergs.de.
<p>Fixed postgresql MoveNext() problems when called repeatedly after EOF. Also
suggested by Heinz Hombergs.
<p>PageExecute() does not rewrite queries if SELECT DISTINCT is used. Requested
by hans#velum.net
<p>Added additional fixes to oci8 SelectLimit handling with aggregate functions
- thx to Christian Bugge for reporting the problem.
<p><b>2.41, 2 Oct 2002</b></p>
<p>Fixed ADODB_COUNTRECS bug in odbc. Thx to Joshua Zoshi jzoshi#hotmail.com.

to 32000.
<p>Revised pivottable.inc.php code. Added better support for aggregate fields.
<p>Fixed mysql text/blob types problem in MetaTypes base class - thx to horacio
degiorgi.
<p>Added SQLDate($fmt,$date) function, which allows an sql date format string
to be generated - useful for group by's.
<p>Fixed bug in oci8 SelectLimit when offset>100.
<p><b>2.40 4 Sept 2002</b></p>
<p>Added new NLS_DATE_FORMAT property to oci8. Suggested by Laurent NAVARRO ln#altidev.com
<p>Now use bind parameters in oci8 selectlimit for better performance.
<p>Fixed interbase replaceQuote for dialect != 1. Thx to "BEGUIN Pierre-Henri
- INFOCOB" phb#infocob.com.
<p>Added white-space check to QA.
<p>Changed unixtimestamp to support fractional seconds (we always round down/floor
the seconds). Thanks to beezly#beezly.org.uk.
<p>Now you can set the trigger_error type your own user-defined type in adodb-errorhandler.inc.php.
Suggested by Claudio Bustos clbustos#entelchile.net.
<p>Added recordset filters with rsfilter.inc.php.
<p>$conn->_rs2rs does not create a new recordset when it detects it is of type
array. Some trickery there as there seems to be a bug in Zend Engine
<p>Added render_pagelinks to adodb-pager.inc.php. Code by "Pablo Costa" pablo#cbsp.com.br.
<p>MetaType() speedup in adodb.inc.php by using hashing instead of switch. Best
performance if constant arrays are supported, as they are in PHP5.
<p>adodb-session.php now updates only the expiry date if the crc32 check indicates
that the data has not been modified.
<p><b>2.31 20 Aug 2002</b></p>
<p>Made changes to pivottable.inc.php due to daniel lucuzaeu's suggestions (we sum the pivottable column if desired).
<p>Fixed ErrorNo() in postgres so it does not depend on _errorMsg property.
<p>Robert Tuttle added support for oracle cursors. See ExecuteCursor().
<p>Fixed Replace() so it works with mysql when updating record where data has not changed. Reported by
Cal Evans (cal#calevans.com).

<p>Fixed mssql SelectLimit( ) bug when distinct used.
<p><b>2.30 1 Aug 2002</b></p>
<p>New GetCol() and CacheGetCol() from ross#bnw.com that returns the first field as a 1 dim array.
<p>We have an empty recordset, but RecordCount() could return -1. Fixed. Reported by "Jonathan Polansky" jonathan#polansky.com.
<p>We now check for session variable changes using strlen($sessval).crc32($sessval).
Formerly we only used crc32().
<p>Informix SelectLimit() problem with $ADODB_COUNTRECS fixed.
<p>Fixed informix SELECT FIRST x DISTINCT, and not SELECT DISTINCT FIRST x - reported by F Riosa
<p>Now default adodb error handlers ignores error if @ used.
<p>If you set $conn->autoRollback=true, we auto-rollback persistent connections for odbc, mysql, oci8, mssql.
Default for autoRollback is false. No need to do so for postgres.
As interbase requires a transaction id (what a flawed api), we don't do it for interbase.
<p>Changed PageExecute() to use non-greedy preg_match when searching for "FROM" keyword.
<p><b>2.20 9 July 2002</b></p>
<p>Added CacheGetOne($secs2cache,$sql), CacheGetRow($secs2cache,$sql), CacheGetAll($secs2cache,$sql).

date offsets. Useful for scheduling appointments.
<p>Added connection properties: leftOuter, rightOuter that hold left and right
outer join operators.
<p>Added connection property: ansiOuter to indicate whether ansi outer joins supported.
<p>New driver <i>mssqlpo</i>, the portable mssql driver, which converts string
concat operator from || to +.
<p>Fixed ms access bug - SelectLimit() did not support ties - fixed.
<p>Karsten Kraus (Karsten.Kraus#web.de), contributed error-handling code to ADONewConnection.
Unfortunately due to backward compat problems, had to rollback most of the changes.
<p>Added new parameter to GetAssoc() to allow returning an array of key-value pairs,
ignoring any additional columns in the recordset. Off by default.
<p>Corrected mssql $conn->sysDate to return only date using convert().
<p>CacheExecute() improved debugging output.
<p>Changed rs2html() so newlines are converted to BR tags. Also optimized rs2html() based
on feedback by "Jerry Workman" jerry#mtncad.com.

<p>Some minor optimizations (mostly removing & references when passing arrays).
<p>Changed GenID() to allows id's larger than the size of an integer.
<p>Added force_session property to oci8 for better updateblob() support.
<p>Fixed PageExecute() which did not work properly with sql containing GROUP BY.
<p><b>2.12 12 June 2002</b></p>
<p>Added toexport.inc.php to export recordsets in CSV and tab-delimited format.
<p>CachePageExecute() does not work - fixed - thx John Huong.
<p>Interbase aliases not set properly in FetchField() - fixed. Thx Stefan Goethals.

Supported by all databases except interbase.
<p><b>2.10 4 June 2002</b></p>
<p>Added uniqueSort property to indicate mssql ORDER BY cols must be unique.
<p>Optimized session handler by crc32 the data. We only write if session data has changed.
<p>adodb_sess_read in adodb-session.php now returns ''correctly - thanks to Jorma Tuomainen, webmaster#wizactive.com
<p>Mssql driver did not throw EXECUTE errors correctly because ErrorMsg() and ErrorNo() called in wrong order.
Pointed out by Alexios Fakos. Fixed.
<p>Changed ado to use client cursors. This fixes BeginTran() problems with ado.
<p>Added handling of timestamp type in ado.
<p>Added to ado_mssql support for insert_id() and affected_rows().
<p>Added support for mssql.datetimeconvert=0, available since php 4.2.0.
<p>Made UnixDate() less strict, so that the time is ignored if present.
<p>Changed quote() so that it checks for magic_quotes_gpc.
<p>Changed maxblobsize for odbc to default to 64000.
<p><b>2.00 13 May 2002</b></p>
<p>Added drivers <i>informix72</i> for pre-7.3 versions, and <i>oci805</i> for
oracle 8.0.5, and postgres64 for postgresql 6.4 and earlier. The postgres and postgres7 drivers
are now identical.
<p>Interbase now partially supports ADODB_FETCH_BOTH, by defaulting to ASSOC mode.
<p>Proper support for blobs in mssql. Also revised blob support code
is base class. Now UpdateBlobFile() calls UpdateBlob() for consistency.
<p>Added support for changed odbc_fetch_into api in php 4.2.0
with $conn-&gt;_has_stupid_odbc_fetch_api_change.
<p>Fixed spelling of tablock locking hint in GenID( ) for mssql.
<p>Added RowLock( ) to several databases, including oci8, informix, sybase, etc.
Fixed where error in mssql RowLock().
<p>Added sysDate and sysTimeStamp properties to most database drivers. These are the sql
functions/constants for that database that return the current date and current timestamp, and
are useful for portable inserts and updates.
<p>Support for RecordCount() caused date handling in sybase and mssql to break.
Fixed, thanks to Toni Tunkkari, by creating derived classes for ADORecordSet_array for
both databases. Generalized using arrayClass property. Also to support RecordCount(),
changed metatype handling for ado drivers. Now the type returned in FetchField
is no longer a number, but the 1-char data type returned by MetaType.
At the same time, fixed a lot of date handling. Now mssql support dmy and mdy date formats.
Also speedups in sybase and mssql with preg_match and ^ in date/timestamp handling.
Added support in sybase and mssql for 24 hour clock in timestamps (no AM/PM).
<p>Extensive revisions to informix driver - thanks to Samuel CARRIERE samuel_carriere#hotmail.com
<p>Added $ok parameter to CommitTrans($ok) for easy rollbacks.
<p>Fixed odbc MetaColumns and MetaTables to save and restore $ADODB_FETCH_MODE.

<p>Fixed regex for GetUpdateSQL() and GetInsertSQL() to support more legal character combinations.
<p><b>1.99 21 April 2002</b></p>
<p>Added emulated RecordCount() to all database drivers if $ADODB_COUNTRECS = true
(which it is by default). Inspired by Cristiano Duarte (cunha17#uol.com.br).
<p>Unified stored procedure support for mssql and oci8. Parameter() and PrepareSP()
functions implemented.
<p>Added support for SELECT FIRST in informix, modified hasTop property to support
this.
<p>Changed csv driver to handle updates/deletes/inserts properly (when Execute() returns true).
Bind params also work now, and raiseErrorFn with csv driver. Added csv driver to QA process.
<p>Better error checking in oci8 UpdateBlob() and UpdateBlobFile().
<p>Added TIME type to MySQL - patch by Manfred h9125297#zechine.wu-wien.ac.at
<p>Prepare/Execute implemented for Interbase/Firebird
<p>Changed some regular expressions to be anchored by /^ $/ for speed.
<p>Added UnixTimeStamp() and UnixDate() to ADOConnection(). Now these functions
are in both ADOConnection and ADORecordSet classes.
<p>Empty recordsets were not cached - fixed.
<p>Thanks to Gaetano Giunta (g.giunta#libero.it) for the oci8 code review. We
didn't agree on everything, but i hoped we agreed to disagree!
<p><b>1.90 6 April 2002</b></p>
<p>Now all database drivers support fetch modes ADODB_FETCH_NUM and ADODB_FETCH_ASSOC, though
still not fully tested. Eg. Frontbase, Sybase, Informix.
<p>NextRecordSet() support for mssql. Contributed by "Sven Axelsson" sven.axelsson#bokochwebb.se
<p>Added blob support for SQL Anywhere. Contributed by Wade Johnson wade#wadejohnson.de
<p>Fixed some security loopholes in server.php. Server.php also supports fetch mode.
<p>Generalized GenID() to support odbc and mssql drivers. Mssql no longer generates GUID's.
<p>Experimental RowLock($table,$where) for mssql.
<p>Properly implemented Prepare() in oci8 and ODBC.
<p>Added Bind() support to oci8 to support Prepare().
<p>Improved error handler. Catches CacheExecute() and GenID() errors now.
<p>Now if you are running php from the command line, debugging messages do not output html formating.
Not 100% complete, but getting there.
<p><b>1.81 22 March 2002</b></p>
<p>Restored default $ADODB_FETCH_MODE = ADODB_FETCH_DEFAULT for backward compatibility.
<p>SelectLimit for oci8 improved - Our FIRST_ROWS optimization now does not overwrite existing hint.
<p>New Sybase SQL Anywhere driver. Contributed by Wade Johnson wade#wadejohnson.de
<p><b>1.80 15 March 2002</b></p>
<p>Redesigned directory structure of ADOdb files. Added new driver directory where
all database drivers reside.
<p>Changed caching algorithm to create subdirectories. Now we scale better.
<p>Informix driver now supports insert_id(). Contribution by "Andrea Pinnisi" pinnisi#sysnet.it
<p>Added experimental ISO date and FetchField support for informix.
<p>Fixed a quoting bug in Execute() with bind parameters, causing problems with blobs.
<p>Mssql driver speedup by 10-15%.
<p>Now in CacheExecute($secs2cache,$sql,...), $secs2cache is optional. If missing, it will
take the value defined in $connection->cacheSecs (default is 3600 seconds). Note that
CacheSelectLimit(), the secs2cache is still compulsory - sigh.
<p>Sybase SQL Anywhere driver (using ODBC) contributed by Wade Johnson wade#wadejohnson.de
<p><b>1.72 8 March 2002</b></p>

<p>MetaDatabases() for postgres contributed by Phil pamelant#nerim.net
<p>Mitchell T. Young (mitch#youngfamily.org) contributed informix driver.
<p>Fixed rs2html() problem. I cannot reproduce, so probably a problem with pre PHP 4.1.0 versions,
when supporting new ADODB_FETCH_MODEs.
<p>Mattia Rossi (mattia#technologist.com) contributed BlobDecode() and UpdateBlobFile() for postgresql
using the postgres specific pg_lo_import()/pg_lo_open() - i don't use them but hopefully others will
find this useful. See <a href="http://phplens.com/lens/lensforum/msgs.php?id=1262">this posting</a>
for an example of usage.
<p>Added UpdateBlobFile() for uploading files to a database.
<p>Made UpdateBlob() compatible with oci8po driver.
<p>Added noNullStrings support to oci8 driver. Oracle changes all ' ' strings to nulls,
so you need to set strings to ' ' to prevent the nullifying of strings. $conn->noNullStrings = true;
will do this for you automatically. This is useful when you define a char column as NOT NULL.
<p>Fixed UnixTimeStamp() bug - wasn't setting minutes and seconds properly. Patch from Agusti Fita i Borrell agusti#anglatecnic.com.
<p>Toni Tunkkari added patch for sybase dates. Problem with spaces in day part of date fixed.
<p><b>1.71 18 Jan 2002</b></p>
<p>Sequence start id support. Now $conn->Gen_ID('seqname', 50) to start sequence from 50.
<p>CSV driver fix for selectlimit, from Andreas - akaiser#vocote.de.
<P>Gam3r spotted that a global variable was undefined in the session handler.
<p>Mssql date regex had error. Fixed - reported by Minh Hoang vb_user#yahoo.com.
<p>DBTimeStamp() and DBDate() now accept iso dates and unix timestamps. This means
that the PostgreSQL handling of dates in GetInsertSQL() and GetUpdateSQL() can
be removed. Also if these functions are passed '' or null or false, we return a SQL null.
<p>GetInsertSQL() and GetUpdateSQL() now accept a new parameter, $magicq to
indicate whether quotes should be inserted based on magic quote settings - suggested by
dj#4ict.com.
<p>Reformated docs slightly based on suggestions by Chris Small.
<p><b>1.65 28 Dec 2001</b></p>

<p>Changed recordset constructor and _initrs() for oci8 so that it returns the field definitions even
if no rows in the recordset. Reported by Rick Hickerson (rhickers#mv.mv.com).
<p>Improved support for postgresql in GetInsertSQL and GetUpdateSQL by

<p><b>1.63 13 Dec 2001</b></p>
Absolute to the adodb-lib.inc.php file not set properly. Fixed.<p>
<p><b>1.62 11 Dec 2001</b></p>
<p>Major speedup of ADOdb for low-end web sites by reducing the php code loading and compiling
cycle. We conditionally compile not so common functions.
Moved csv code to adodb-csvlib.inc.php to reduce adodb.inc.php parsing. This file
is loaded only when the csv/proxy driver is used, or CacheExecute() is run.
Also moved PageExecute(), GetSelectSQL() and GetUpdateSQL() core code to adodb-lib.inc.php.
This reduced the 70K main adodb.inc.php file to 55K, and since at least 20K of the file
is comments, we have reduced 50K of code in adodb.inc.php to 35K. There
should be 35% reduction in memory and thus 35% speedup in compiling the php code for the
main adodb.inc.php file.
<p>Highly tuned SelectLimit() for oci8 for massive speed improvements on large files.
Selecting 20 rows starting from the 20,000th row of a table is now 7 times faster.
Thx to Tomas V V Cox.
<p>Allow . and # in table definitions in GetInsertSQL and GetUpdateSQL.
See ADODB_TABLE_REGEX constant. Thx to Ari Kuorikoski.
<p>Added ADODB_PREFETCH_ROWS constant, defaulting to 10. This determines the number
of records to prefetch in a SELECT statement. Only used by oci8.</p>
<p>Added high portability Oracle class called oci8po. This uses ? for bind variables, and
lower cases column names.</p>
<p>Now all database drivers support $ADODB_FETCH_MODE, including interbase, ado, and odbc:
ADODB_FETCH_NUM and ADODB_FETCH_ASSOC. ADODB_FETCH_BOTH is not fully implemented for all
database drivers.
<p><b>1.61 Nov 2001</b></p>
<p>Added PO_RecordCount() and PO_Insert_ID(). PO stands for portable. Pablo Roca
[pabloroca#mvps.org]</p>
<p>GenID now returns 0 if not available. Safer is that you should check $conn->hasGenID
for availability.</p>
<p>M'soft ADO we now correctly close recordset in _close() peterd#telephonetics.co.uk</p>
<p>MSSQL now supports GenID(). It generates a 16-byte GUID from mssql newid()
function.</p>
<p>Changed ereg_replace to preg_replace in SelectLimit. This is a fix for mssql.
Ereg doesn't support t or n! Reported by marino Carlos xaplo#postnuke-espanol.org</p>
<p>Added $recordset->connection. This is the ADOConnection object for the recordset.
Works with cached and normal recordsets. Surprisingly, this had no affect on performance!</p>
<p><b>1.54 15 Nov 2001</b></p>
Fixed some more bugs in PageExecute(). I am getting sick of bug in this and will have to
reconsider my QA here. The main issue is that I don't use PageExecute() and
to check whether it is working requires a visual inspection of the html generated currently.
It is possible to write a test script but it would be quite complicated :(
<p> More speedups of SelectLimit() for DB2, Oci8, access, vfp, mssql.
<p>
<p><b>1.53 7 Nov 2001</b></p>

<p>Oci8 SelectLimit() speedup by using OCIFetch().
<p>Oci8 was mistakenly reporting errors when $db->debug = true.
<p>If a connection failed with ODBC, it was not correctly reported - fixed.
<p>_connectionID was inited to -1, changed to false.
<p>Added $rs->FetchRow(), to simplify API, ala PEAR DB
<p>Added PEAR DB compat mode, which is still faster than PEAR! See adodb-pear.inc.php.
<p>Removed postgres pconnect debugging statement.
<p><b>1.50 31 Oct 2001</b></p>
<p>ADOdbConnection renamed to ADOConnection, and ADOdbFieldObject to ADOFieldObject.
<p>PageExecute() now checks for empty $rs correctly, and the errors in the docs on this subject have been fixed.
<p>odbc_error() does not return 6 digit error correctly at times. Implemented workaround.
<p>Added ADORecordSet_empty class. This will speedup INSERTS/DELETES/UPDATES because the return
object created is much smaller.
<p>Added Prepare() to odbc, and oci8 (but doesn't work properly for oci8 still).
<p>Made pgsql a synonym for postgre7, and changed SELECT LIMIT to use OFFSET for compat with
postgres 7.2.
<p>Revised adodb-cryptsession.php thanks to Ari.
<p>Set resources to false on _close, to force freeing of resources.
<p>Added adodb-errorhandler.inc.php, adodb-errorpear.inc.php and raiseErrorFn on Freek's urging.
<p>GetRowAssoc($toUpper=true): $toUpper added as default.
<p>Errors when connecting to a database were not captured formerly. Now we do it correctly.

<p>Many bug fixes thanks to "GaM3R (Cameron)" &lt;gamr#outworld.cx>. Some session changes due to Gam3r.
<p>Fixed qstr() to quote also.
<p>rs2html() now pretty printed.
<p>Jonathan Younger jyounger#unilab.com contributed the great idea GetUpdateSQL() and GetInsertSQL() which
generates SQL to update and insert into a table from a recordset. Modify the recordset fields
array, then can this function to generate the SQL (the SQL is not executed).
<p>"Nicola Fankhauser" &lt;nicola.fankhauser#couniq.com> found some bugs in date handling for mssql.</p>
<p>Added minimal Oracle support for LOBs. Still under development.</p>
Added $ADODB_FETCH_MODE so you can control whether recordsets return arrays which are
numeric, associative or both. This is a global variable you set. Currently only MySQL, Oci8, Postgres
drivers support this.
<p>PostgreSQL properly closes recordsets now. Reported by several people.

<p>Updated 6 Oct 2006. Added OffsetDate example.
<p>Updated 18 Sep 2003. Added Portable Native SQL section.
<p>
If you are writing an application that is used in multiple environments and
operating systems, you need to plan to support multiple databases. This article
is based on my experiences with multiple database systems, stretching from 4th
Dimension in my Mac days, to the databases I currently use, which are: Oracle,
FoxPro, Access, MS SQL Server and MySQL. Although most of the advice here applies
to using SQL with Perl, Python and other programming languages, I will focus on PHP and how
the <a href="http://adodb.sourceforge.net/">ADOdb</a> database abstraction library
offers some solutions.<p></p>
<p>Most database vendors practice product lock-in. The best or fastest way to
do things is often implemented using proprietary extensions to SQL. This makes
it extremely hard to write portable SQL code that performs well under all conditions.
When the first ANSI committee got together in 1984 to standardize SQL, the database
vendors had such different implementations that they could only agree on the
core functionality of SQL. Many important application specific requirements
were not standardized, and after so many years since the ANSI effort began,
it looks as if much useful database functionality will never be standardized.
Even though ANSI-92 SQL has codified much more, we still have to implement portability
at the application level.</p>
<h3><b>Selects</b></h3>
<p>The SELECT statement has been standardized to a great degree. Nearly every
database supports the following:</p>
<p>SELECT [cols] FROM [tables]<br>
&nbsp;&nbsp;[WHERE conditions]<br>
&nbsp; [GROUP BY cols]<br>
&nbsp; [HAVING conditions] <br>
&nbsp; [ORDER BY cols]</p>
<p>But so many useful techniques can only be implemented by using proprietary
extensions. For example, when writing SQL to retrieve the first 10 rows for
paging, you could write...</p>
<table width="80%" border="1" cellspacing="0" cellpadding="0" align="center">
<tr>
<td><b>Database</b></td>
<td><b>SQL Syntax</b></td>
</tr>
<tr>
<td>DB2</td>
<td>select * from table fetch first 10 rows only</td>
</tr>
<tr>
<td>Informix</td>
<td>select first 10 * from table</td>
</tr>
<tr>
<td>Microsoft SQL Server and Access</td>
<td>select top 10 * from table</td>
</tr>
<tr>
<td>MySQL and PostgreSQL</td>
<td>select * from table limit 10</td>
</tr>
<tr>
<td>Oracle 8i</td>
<td>select * from (select * from table) where rownum &lt;= 10</td>
</tr>
</table>
<p>This feature of getting a subset of data is so useful that in the PHP class
library ADOdb, we have a SelectLimit( ) function that allows you to hide the
implementation details within a function that will rewrite your SQL for you:</p>
<pre>$connection-&gt;SelectLimit('select * from table', 10);
</pre>
<p><b>Selects: Fetch Modes</b></p>
<p>PHP allows you to retrieve database records as arrays. You can choose to have
the arrays indexed by field name or number. However different low-level PHP
database drivers are inconsistent in their indexing efforts. ADOdb allows you
to determine your prefered mode. You set this by setting the variable $ADODB_FETCH_MODE
to either of the constants ADODB_FETCH_NUM (for numeric indexes) or ADODB_FETCH_ASSOC
(using field names as an associative index).</p>
<p>The default behaviour of ADOdb varies depending on the database you are using.
For consistency, set the fetch mode to either ADODB_FETCH_NUM (for speed) or
ADODB_FETCH_ASSOC (for convenience) at the beginning of your code. </p>
<p><b>Selects: Counting Records</b></p>
<p>Another problem with SELECTs is that some databases do not return the number
of rows retrieved from a select statement. This is because the highest performance
databases will return records to you even before the last record has been found.
</p>
<p>In ADOdb, RecordCount( ) returns the number of rows returned, or will emulate
it by buffering the rows and returning the count after all rows have been returned.
This can be disabled for performance reasons when retrieving large recordsets
by setting the global variable $ADODB_COUNTRECS = false. This variable is checked
every time a query is executed, so you can selectively choose which recordsets
to count.</p>
<p>If you prefer to set $ADODB_COUNTRECS = false, ADOdb still has the PO_RecordCount(
) function. This will return the number of rows, or if it is not found, it will
return an estimate using SELECT COUNT(*):</p>
<pre>$rs = $db-&gt;Execute(&quot;select * from table where state=$state&quot;);
$numrows = $rs-&gt;PO_RecordCount('table', &quot;state=$state&quot;);</pre>
<p><b>Selects: Locking</b> </p>
<p>SELECT statements are commonly used to implement row-level locking of tables.
Other databases such as Oracle, Interbase, PostgreSQL and MySQL with InnoDB
do not require row-level locking because they use versioning to display data
consistent with a specific point in time.</p>
<p>Currently, I recommend encapsulating the row-level locking in a separate function,
such as RowLock($table, $where):</p>
<pre>$connection-&gt;BeginTrans( );
$connection-&gt;RowLock($table, $where); </pre>
<pre><font color=green># some operation</font></pre>
<pre>if ($ok) $connection-&gt;CommitTrans( );
else $connection-&gt;RollbackTrans( );
</pre>
<p><b>Selects: Outer Joins</b></p>
<p>Not all databases support outer joins. Furthermore the syntax for outer joins
differs dramatically between database vendors. One portable (and possibly slower)
method of implementing outer joins is using UNION.</p>
<p>For example, an ANSI-92 left outer join between two tables t1 and t2 could
look like:</p>
<pre>SELECT t1.col1, t1.col2, t2.cola <br> FROM t1 <i>LEFT JOIN</i> t2 ON t1.col = t2.col</pre>
<p>This can be emulated using:</p>
<pre>SELECT t1.col1, t1.col2, t2.cola FROM t1, t2 <br> WHERE t1.col = t2.col
UNION ALL
SELECT col1, col2, null FROM t1 <br> WHERE t1.col not in (select distinct col from t2)
</pre>
<p>Since ADOdb 2.13, we provide some hints in the connection object as to legal
join variations. This is still incomplete and sometimes depends on the database
version you are using, but is useful as a general guideline:</p>
<p><font face="Courier New, Courier, mono">$conn-&gt;leftOuter</font>: holds the
operator used for left outer joins (eg. '*='), or false if not known or not
available.<br>
<font face="Courier New, Courier, mono">$conn-&gt;rightOuter</font>: holds the
operator used for right outer joins (eg '=*'), or false if not known or not
available.<br>
<font face="Courier New, Courier, mono">$conn-&gt;ansiOuter</font>: boolean
that if true means that ANSI-92 style outer joins are supported, or false if
not known.</p>
<h3><b>Inserts</b> </h3>
<p>When you create records, you need to generate unique id's for each record.
There are two common techniques: (1) auto-incrementing columns and (2) sequences.
</p>
<p>Auto-incrementing columns are supported by MySQL, Sybase and Microsoft Access
and SQL Server. However most other databases do not support this feature. So
for portability, you have little choice but to use sequences. Sequences are
special functions that return a unique incrementing number every time you call
it, suitable to be used as database keys. In ADOdb, we use the GenID( ) function.
It has takes a parameter, the sequence name. Different tables can have different
sequences. </p>
<pre>$id = $connection-&gt;GenID('sequence_name');<br>$connection-&gt;Execute(&quot;insert into table (id, firstname, lastname) <br> values ($id, $firstname, $lastname)&quot;);</pre>
<p>For databases that do not support sequences natively, ADOdb emulates sequences
by creating a table for every sequence.</p>
<h3><b>Binding</b></h3>
<p>Binding variables in an SQL statement is another tricky feature. Binding is
useful because it allows pre-compilation of SQL. When inserting multiple records
into a database in a loop, binding can offer a 50% (or greater) speedup. However
many databases such as Access and MySQL do not support binding natively and
there is some overhead in emulating binding. Furthermore, different databases
(specificly Oracle!) implement binding differently. My recommendation is to
use binding if your database queries are too slow, but make sure you are using
a database that supports it like Oracle. </p>
<p>ADOdb supports portable Prepare/Execute with:</p>
<pre>$stmt = $db-&gt;Prepare('select * from customers where custid=? and state=?');
$rs = $db-&gt;Execute($stmt, array($id,'New York'));</pre>
<p>Oracle uses named bind placeholders, not "?", so to support portable binding, we have Param() that generates
the correct placeholder (available since ADOdb 3.92):
<pre><font color="#000000">$sql = <font color="#993300">'insert into table (col1,col2) values ('</font>.$DB-&gt;Param('a').<font color="#993300">','</font>.$DB-&gt;Param('b').<font color="#993300">')'</font>;
<font color="#006600"># generates 'insert into table (col1,col2) values (?,?)'
# or 'insert into table (col1,col2) values (:a,:b)</font>'
$stmt = $DB-&gt;Prepare($sql);
$stmt = $DB-&gt;Execute($stmt,array('one','two'));
</font></pre>
<a name="native"></a>
<h2>Portable Native SQL</h2>
<p>ADOdb provides the following functions for portably generating SQL functions
as strings to be merged into your SQL statements (some are only available since
ADOdb 3.92): </p>
<table width="75%" border="1" align=center>
<tr>
<td width=30%><b>Function</b></td>

string formatted for INSERT/UPDATE</td>
</tr>
<tr>
<td>SQLDate($date, $fmt)</td>
<td>Portably generate a date formatted using $fmt mask, for use in SELECT
statements.</td>
</tr>
<tr>

</td>
</tr>
<tr><td>$db->substr</td><td>Property that holds the name of the SQL substring function.
</td></tr>
</table>
<p>&nbsp; </p>
<h2>DDL and Tuning</h2>
There are database design tools such as ERWin or Dezign that allow you to generate data definition language commands such as ALTER TABLE or CREATE INDEX from Entity-Relationship diagrams.
<p>
However if you prefer to use a PHP-based table creation scheme, adodb provides you with this feature. Here is the code to generate the SQL to create a table with:
<ol>
<li> Auto-increment primary key 'ID', </li>
<li>The person's 'NAME' VARCHAR(32) NOT NULL and defaults to '', </li>
<li>The date and time of record creation 'CREATED', </li>
<li> The person's 'AGE', defaulting to 0, type NUMERIC(16). </li>
</ol>
<p>
Also create a compound index consisting of 'NAME' and 'AGE':
<pre>
$datadict = <strong>NewDataDictionary</strong>($connection);
$flds = "
<font color="#660000"> ID I AUTOINCREMENT PRIMARY,
NAME C(32) DEFAULT '' NOTNULL,
CREATED T DEFTIMESTAMP,
AGE N(16) DEFAULT 0</font>
";
$sql1 = $datadict-><strong>CreateTableSQL</strong>('tabname', $flds);
$sql2 = $datadict-><strong>CreateIndexSQL</strong>('idx_name_age', 'tabname', 'NAME,AGE');
</pre>
<h3>Data Types</h3>
<p>Stick to a few data types that are available in most databases. Char, varchar
and numeric/number are supported by most databases. Most other data types (including
integer, boolean and float) cannot be relied on being available. I recommend
using char(1) or number(1) to hold booleans. </p>
<p>Different databases have different ways of representing dates and timestamps/datetime.
ADOdb attempts to display all dates in ISO (YYYY-MM-DD) format. ADOdb also provides
DBDate( ) and DBTimeStamp( ) to convert dates to formats that are acceptable
to that database. Both functions accept Unix integer timestamps and date strings
in ISO format.</p>
<pre>$date1 = $connection-&gt;DBDate(time( ));<br>$date2 = $connection-&gt;DBTimeStamp('2002-02-23 13:03:33');</pre>
<p>We also provide functions to convert database dates to Unix timestamps:</p>
<pre>$unixts = $recordset-&gt;UnixDate('#2002-02-30#'); <font color="green"># MS Access date =gt; unix timestamp</font></pre>
<p>For date calculations, we have OffsetDate which allows you to calculate dates such as <i>yesterday</i> and <i>next week</i> in a RDBMS independant fashion. For example, if we want to set a field to 6 hour from now, use:
<pre>
$sql = 'update table set dtimefld='.$db-&gt;OffsetDate($db-&gtsysTimeStamp, 6/24).' where ...';
</pre>
<p>The maximum length of a char/varchar field is also database specific. You can
only assume that field lengths of up to 250 characters are supported. This is
normally impractical for web based forum or content management systems. You
will need to be familiar with how databases handle large objects (LOBs). ADOdb
implements two functions, UpdateBlob( ) and UpdateClob( ) that allow you to
update fields holding Binary Large Objects (eg. pictures) and Character Large
Objects (eg. HTML articles):</p>
<pre><font color=green># for oracle </font>
$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1,empty_blob())');
$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1');
<font color=green># non-oracle databases</font>
$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1, null)');
$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1');
</pre>
<p>Null handling is another area where differences can occur. This is a mine-field,
because 3-value logic is tricky.
<p>In general, I avoid using nulls except for dates and default all my numeric
and character fields to 0 or the empty string. This maintains consistency with
PHP, where empty strings and zero are treated as equivalent, and avoids SQL
ambiguities when you use the ANY and EXISTS operators. However if your database
has significant amounts of missing or unknown data, using nulls might be a good
idea.
<p>
ADOdb also supports a portable <a href=http://phplens.com/adodb/reference.functions.concat.html#ifnull>IfNull</a> function, so you can define what to display
if the field contains a null.
<h3><b>Stored Procedures</b></h3>
<p>Stored procedures are another problem area. Some databases allow recordsets
to be returned in a stored procedure (Microsoft SQL Server and Sybase), and
others only allow output parameters to be returned. Stored procedures sometimes
need to be wrapped in special syntax. For example, Oracle requires such code
to be wrapped in an anonymous block with BEGIN and END. Also internal sql operators
and functions such as +, ||, TRIM( ), SUBSTR( ) or INSTR( ) vary between vendors.
</p>
<p>An example of how to call a stored procedure with 2 parameters and 1 return
value follows:</p>
<pre> switch ($db->databaseType) {
case '<font color="#993300">mssql</font>':
$sql = <font color="#000000"><font color="#993333">'<font color="#993300">SP_RUNSOMETHING</font>'</font></font>; break;
case '<font color="#993300">oci8</font>':
$sql =
<font color="#993300"> </font><font color="#000000"><font color="#993300">&quot;declare RETVAL integer;begin :RETVAL := </font><font color="#000000"><font color="#993333"><font color="#993300">SP_RUNSOMETHING</font></font></font><font color="#993300">(:myid,:group);end;&quot;;
</font> break;</font>
default:
die('<font color="#993300">Unsupported feature</font>');
}
<font color="#000000"><font color="green"> # @RETVAL = SP_RUNSOMETHING @myid,@group</font>
$stmt = $db-&gt;PrepareSP($sql); <br> $db-&gt;Parameter($stmt,$id,'<font color="#993300">myid</font>');
$db-&gt;Parameter($stmt,$group,'<font color="#993300">group</font>');
<font color="green"># true indicates output parameter<br> </font>$db-&gt;Parameter($stmt,$ret,'<font color="#993300">RETVAL</font>',true);
$db-&gt;Execute($stmt); </font></pre>
<p>As you can see, the ADOdb API is the same for both databases. But the stored
procedure SQL syntax is quite different between databases and is not portable,
so be forewarned! However sometimes you have little choice as some systems only
allow data to be accessed via stored procedures. This is when the ultimate portability
solution might be the only solution: <i>treating portable SQL as a localization
exercise...</i></p>
<h3><b>SQL as a Localization Exercise</b></h3>
<p> In general to provide real portability, you will have to treat SQL coding
as a localization exercise. In PHP, it has become common to define separate
language files for English, Russian, Korean, etc. Similarly, I would suggest
you have separate Sybase, Intebase, MySQL, etc files, and conditionally include
the SQL based on the database. For example, each MySQL SQL statement would be
stored in a separate variable, in a file called 'mysql-lang.inc.php'.</p>
<pre>$sqlGetPassword = '<font color="#993300">select password from users where userid=%s</font>';
$sqlSearchKeyword = quot;<font color="#993300">SELECT * FROM articles WHERE match (title,body) against (%s</font>)&quot;;</pre>
<p>In our main PHP file:</p>
<pre><font color=green># define which database to load...</font>
<b>$database = '<font color="#993300">mysql</font>';
include_once(&quot;<font color="#993300">$database-lang.inc.php</font>&quot;);</b>
$db = NewADOConnection($database);
$db->PConnect(...) or die('<font color="#993300">Failed to connect to database</font>');
<font color=green># search for a keyword $word</font>
$rs = $db-&gt;Execute(sprintf($sqlSearchKeyWord,$db-&gt;qstr($word)));</pre>
<p>Note that we quote the $word variable using the qstr( ) function. This is because
each database quotes strings using different conventions.</p>
<p>
<h3>Final Thoughts</h3>
<p>The best way to ensure that you have portable SQL is to have your data tables designed using
sound principles. Learn the theory of normalization and entity-relationship diagrams and model
your data carefully. Understand how joins and indexes work and how they are used to tune performance.

<h1>Tutorial: Moving from MySQL to ADODB</h1>
<pre> You say eether and I say eyether,
You say neether and I say nyther;
Eether, eyether, neether, nyther -
Let's call the whole thing off !
<br>
You like potato and I like po-tah-to,
You like tomato and I like to-mah-to;
Potato, po-tah-to, tomato, to-mah-to -
Let's call the whole thing off !
</pre>
<p>I love this song, especially the version with Louis Armstrong and Ella singing
duet. It is all about how hard it is for two people in love to be compatible
with each other. It's about compromise and finding a common ground, and that's
what this article is all about.
<p>PHP is all about creating dynamic web-sites with the least fuss and the most
fun. To create these websites we need to use databases to retrieve login information,
to splash dynamic news onto the web page and store forum postings. So let's
say we were using the popular MySQL database for this. Your company has done
such a fantastic job that the Web site is more popular than your wildest dreams.
You find that MySQL cannot scale to handle the workload; time to switch databases.
<p> Unfortunately in PHP every database is accessed slightly differently. To connect
to MySQL, you would use <i>mysql_connect()</i>; when you decide to upgrade to
Oracle or Microsoft SQL Server, you would use <i>ocilogon() </i>or <i>mssql_connect()</i>
respectively. What is worse is that the parameters you use for the different
connect functions are different also.. One database says po-tato, the other
database says pota-to. Oh-oh.
<h3>Let's NOT call the whole thing off</h3>
<p>A database wrapper library such as ADODB comes in handy when you need to ensure portability. It provides
you with a common API to communicate with any supported database so you don't have to call things off. <p>
<p>ADODB stands for Active Data Objects DataBase (sorry computer guys are sometimes
not very original). ADODB currently supports MySQL, PostgreSQL, Oracle, Interbase,
Microsoft SQL Server, Access, FoxPro, Sybase, ODBC and ADO. You can download
ADODB from <a href=http://php.weblogs.com/adodb></a><a href="http://php.weblogs.com/adodb">http://php.weblogs.com/adodb</a>.
<h3>MySQL Example</h3>
<p>The most common database used with PHP is MySQL, so I guess you should be familiar
with the following code. It connects to a MySQL server at <i>localhost</i>,
database <i>mydb</i>, and executes an SQL select statement. The results are
printed, one line per row.
<pre><font color="#666600">$db = <b>mysql_connect</b>(&quot;localhost&quot;, &quot;root&quot;, &quot;password&quot;);
<b>mysql_select_db</b>(&quot;mydb&quot;,$db);</font>
<font color="#660000">$result = <b>mysql_query</b>(&quot;SELECT * FROM employees&quot;,$db)</font><code><font color="#663300">;
if ($result === false) die(&quot;failed&quot;);</font></code>
<font color="#006666"><b>while</b> ($fields =<b> mysql_fetch_row</b>($result)) &#123;
<b>for</b> ($i=0, $max=sizeof($fields); $i &lt; $max; $i++) &#123;
<b>print</b> $fields[$i].' ';
&#125;
<b>print</b> &quot;&lt;br&gt;\n&quot;;
&#125;</font>
</pre>
<p>The above code has been color-coded by section. The first section is the connection
phase. The second is the execution of the SQL, and the last section is displaying
the fields. The <i>while</i> loop scans the rows of the result, while the <i>for</i>
loop scans the fields in one row.</p>
<p>Here is the equivalent code in ADODB</p>
<pre><b><font color="#666600"> include(&quot;adodb.inc.php&quot;);</font></b><font color="#666600">
$db = <b>NewADOConnection</b>('mysql');
$db-&gt;<b>Connect</b>(&quot;localhost&quot;, &quot;root&quot;, &quot;password&quot;, &quot;mydb&quot;);</font>
<font color="#663300">$result = $db-&gt;<b>Execute</b>(&quot;SELECT * FROM employees&quot;);
</font><font color="#663300"></font><code><font color="#663300">if ($result === false) die(&quot;failed&quot;)</font></code><code><font color="#663300">;</font></code>
<font color="#006666"><b>while</b> (!$result-&gt;EOF) &#123;
<b>for</b> ($i=0, $max=$result-&gt;<b>FieldCount</b>(); $i &lt; $max; $i++)
<b>print</b> $result-&gt;fields[$i].' ';
$result-&gt;<b>MoveNext</b>();
<b>print</b> &quot;&lt;br&gt;\n&quot;;
&#125;</font> </pre>
<p></p>
<p>Now porting to Oracle is as simple as changing the second line to <code>NewADOConnection('oracle')</code>.
Let's walk through the code...</p>
<h3>Connecting to the Database</h3>
<p></p>
<pre><b><font color="#666600">include(&quot;adodb.inc.php&quot;);</font></b><font color="#666600">
$db = <b>NewADOConnection</b>('mysql');
$db-&gt;<b>Connect</b>(&quot;localhost&quot;, &quot;root&quot;, &quot;password&quot;, &quot;mydb&quot;);</font></pre>
<p>The connection code is a bit more sophisticated than MySQL's because our needs
are more sophisticated. In ADODB, we use an object-oriented approach to managing
the complexity of handling multiple databases. We have different classes to
handle different databases. If you aren't familiar with object-oriented programing,
don't worry -- the complexity is all hidden away in the<code> NewADOConnection()</code>
function.</p>
<p>To conserve memory, we only load the PHP code specific to the database you
are connecting to. We do this by calling <code>NewADOConnection(databasedriver)</code>.
Legal database drivers include <i>mysql, mssql, oracle, oci8, postgres, sybase,
vfp, access, ibase </i>and many others.</p>
<p>Then we create a new instance of the connection class by calling <code>NewADOConnection()</code>.
Finally we connect to the database using <code>$db-&gt;Connect(). </code></p>
<h3>Executing the SQL</h3>
<p><code><font color="#663300">$result = $db-&gt;<b>Execute</b>(&quot;SELECT *
FROM employees&quot;);<br>
if ($result === false) die(&quot;failed&quot;)</font></code><code><font color="#663300">;</font></code>
<br>
</p>
<p>Sending the SQL statement to the server is straight forward. Execute() will
return a recordset object on successful execution. You should check $result
as we do above.
<p>An issue that confuses beginners is the fact that we have two types of objects
in ADODB, the connection object and the recordset object. When do we use each?
<p>The connection object ($db) is responsible for connecting to the database,
formatting your SQL and querying the database server. The recordset object ($result)
is responsible for retrieving the results and formatting the reply as text or
as an array.
<p>The only thing I need to add is that ADODB provides several helper functions
for making INSERT and UPDATE statements easier, which we will cover in the Advanced
section.
<h3>Retrieving the Data<br>
</h3>
<pre><font color="#006666"><b>while</b> (!$result-&gt;EOF) &#123;
<b>for</b> ($i=0, $max=$result-&gt;<b>FieldCount</b>(); $i &lt; $max; $i++)
<b>print</b> $result-&gt;fields[$i].' ';
$result-&gt;<b>MoveNext</b>();
<b>print</b> &quot;&lt;br&gt;\n&quot;;
&#125;</font></pre>
<p>The paradigm for getting the data is that it's like reading a file. For every
line, we check first whether we have reached the end-of-file (EOF). While not
end-of-file, loop through each field in the row. Then move to the next line
(MoveNext) and repeat.
<p>The <code>$result-&gt;fields[]</code> array is generated by the PHP database
extension. Some database extensions do not index the array by field name.
To force indexing by name - that is associative arrays -
use the $ADODB_FETCH_MODE global variable.
<pre>
$<b>ADODB_FETCH_MODE</b> = ADODB_FETCH_NUM;
$rs1 = $db->Execute('select * from table');
$<b>ADODB_FETCH_MODE</b> = ADODB_FETCH_ASSOC;
$rs2 = $db->Execute('select * from table');
print_r($rs1->fields); // shows <i>array([0]=>'v0',[1] =>'v1')</i>
print_r($rs2->fields); // shows <i>array(['col1']=>'v0',['col2'] =>'v1')</i>
</pre>
<p>
As you can see in the above example, both recordsets store and use different fetch modes
based on the $ADODB_FETCH_MODE setting when the recordset was created by Execute().</p>
<h2>ADOConnection<a name="ADOConnection"></a></h2>
<p>Object that performs the connection to the database, executes SQL statements
and has a set of utility functions for standardising the format of SQL statements
for issues such as concatenation and date formats.</p>
<h3>Other Useful Functions</h3>
<p><code>$recordset-&gt;Move($pos)</code> scrolls to that particular row. ADODB supports forward
scrolling for all databases. Some databases will not support backwards scrolling.
This is normally not a problem as you can always cache records to simulate backwards
scrolling.
<p><code>$recordset-&gt;RecordCount()</code> returns the number of records accessed by the
SQL statement. Some databases will return -1 because it is not supported.
<p><code>$recordset-&gt;GetArray()</code> returns the result as an array.
<p><code>rs2html($recordset)</code> is a function that is generates a HTML table based on the
$recordset passed to it. An example with the relevant lines in bold:
<pre> include('adodb.inc.php');
<b>include('tohtml.inc.php');</b> /* includes the rs2html function */
$conn = ADONewConnection('mysql');
$conn-&gt;PConnect('localhost','userid','password','database');
$rs = $conn-&gt;Execute('select * from table');
<b> rs2html($rs)</b>; /* recordset to html table */ </pre>
<p>There are many other helper functions that are listed in the documentation available at <a href="http://php.weblogs.com/adodb_manual"></a><a href="http://php.weblogs.com/adodb_manual">http://php.weblogs.com/adodb_manual</a>.
<h2>Advanced Material</h2>
<h3>Inserts and Updates </h3>
<p>Let's say you want to insert the following data into a database.
<p><b>ID</b> = 3<br>
<b>TheDate</b>=mktime(0,0,0,8,31,2001) /* 31st August 2001 */<br>
<b>Note</b>= sugar why don't we call it off
<p>When you move to another database, your insert might no longer work.</p>
<p>The first problem is that each database has a different default date format.
MySQL expects YYYY-MM-DD format, while other databases have different defaults.
ADODB has a function called DBDate() that addresses this issue by converting
converting the date to the correct format.</p>
<p>The next problem is that the <b>don't</b> in the Note needs to be quoted. In
MySQL, we use <b>don\'t</b> but in some other databases (Sybase, Access, Microsoft
SQL Server) we use <b>don''t. </b>The qstr() function addresses this issue.</p>
<p>So how do we use the functions? Like this:</p>
<pre>$sql = &quot;INSERT INTO table (id, thedate,note) values (&quot;
. $<b>ID</b> . ','
. $db-&gt;DBDate($<b>TheDate</b>) .','
. $db-&gt;qstr($<b>Note</b>).&quot;)&quot;;
$db-&gt;Execute($sql);</pre>
<p>ADODB also supports <code>$connection-&gt;Affected_Rows()</code> (returns the
number of rows affected by last update or delete) and <code>$recordset-&gt;Insert_ID()</code>
(returns last autoincrement number generated by an insert statement). Be forewarned
that not all databases support the two functions.<br>
</p>
<h3>MetaTypes</h3>
<p>You can find out more information about each of the fields (I use the words
fields and columns interchangebly) you are selecting by calling the recordset
method <code>FetchField($fieldoffset)</code>. This will return an object with
3 properties: name, type and max_length.
<pre>For example:</pre>
<pre>$recordset = $conn-&gt;Execute(&quot;select adate from table&quot;);<br>$f0 = $recordset-&gt;FetchField(0);
</pre>
<p>Then <code>$f0-&gt;name</code> will hold <i>'adata'</i>, <code>$f0-&gt;type</code>
will be set to '<i>date'</i>. If the max_length is unknown, it will be set to
-1.
<p>One problem with handling different databases is that each database often calls
the same type by a different name. For example a <i>timestamp</i> type is called
<i>datetime</i> in one database and <i>time</i> in another. So ADODB has a special
<code>MetaType($type, $max_length)</code> function that standardises the types
to the following:
<p>C: character and varchar types<br>
X: text or long character (eg. more than 255 bytes wide).<br>
B: blob or binary image<br>
D: date<br>
T: timestamp<br>
L: logical (boolean)<br>
I: integer<br>
N: numeric (float, double, money)
<p>In the above date example,
<p><code>$recordset = $conn-&gt;Execute(&quot;select adate from table&quot;);<br>
$f0 = $recordset-&gt;FetchField(0);<br>
$type = $recordset-&gt;MetaType($f0-&gt;type, $f0-&gt;max_length);<br>
print $type; /* should print 'D'</code> */
<p>
<p><b>Select Limit and Top Support</b>
<p>ADODB has a function called $connection->SelectLimit($sql,$nrows,$offset) that allows
you to retrieve a subset of the recordset. This will take advantage of native
SELECT TOP on Microsoft products and SELECT ... LIMIT with PostgreSQL and MySQL, and
emulated if the database does not support it.
<p><b>Caching Support</b>
<p>ADODB allows you to cache recordsets in your file system, and only requery the database
server after a certain timeout period with $connection->CacheExecute($secs2cache,$sql) and
$connection->CacheSelectLimit($secs2cache,$sql,$nrows,$offset).
<p><b>PHP4 Session Handler Support</b>
<p>ADODB also supports PHP4 session handlers. You can store your session variables
in a database for true scalability using ADODB. For further information, visit
<a href="http://php.weblogs.com/adodb-sessions"></a><a href="http://php.weblogs.com/adodb-sessions">http://php.weblogs.com/adodb-sessions</a>
<h3>Commercial Use Encouraged</h3>
<p>If you plan to write commercial PHP applications that you want to resell, you should consider ADODB. It has been released using the lesser GPL, which means you can legally include it in commercial applications, while keeping your code proprietary. Commercial use of ADODB is strongly encouraged! We are using it internally for this reason.<p>
<h2>Conclusion</h2>
<p>As a thank you for finishing this article, here are the complete lyrics for
<i>let's call the whole thing off</i>.<br>
<br>
<pre>
Refrain
<br>
You say eether and I say eyether,
You say neether and I say nyther;
Eether, eyether, neether, nyther -
Let's call the whole thing off !
<br>
You like potato and I like po-tah-to,
You like tomato and I like to-mah-to;
Potato, po-tah-to, tomato, to-mah-to -
Let's call the whole thing off !
<br>
But oh, if we call the whole thing off, then we must part.
And oh, if we ever part, then that might break my heart.
<br>
So, if you like pajamas and I like pa-jah-mas,
I'll wear pajamas and give up pa-jah-mas.
For we know we
Need each other, so we
Better call the calling off off.
Let's call the whole thing off !
<br>
Second Refrain
<br>
You say laughter and I say lawfter,
You say after and I say awfter;
Laughter, lawfter, after, awfter -
Let's call the whole thing off !
<br>
You like vanilla and I like vanella,
You, sa's'parilla and I sa's'parella;
Vanilla, vanella, choc'late, strawb'ry -
Let's call the whole thing off !
<br>
But oh, if we call the whole thing off, then we must part.
And oh, if we ever part, then that might break my heart.
<br>
So, if you go for oysters and I go for ersters,
I'll order oysters and cancel the ersters.
For we know we
Need each other, so we
Better call the calling off off.
Let's call the whole thing off !

NOTE: This driver requires the Advantage PHP client libraries, which
can be downloaded for free via:
http://devzone.advantagedatabase.com/dz/content.aspx?key=20
DELPHI FOR PHP USERS:
The following steps can be taken to utilize this driver from the
CodeGear Delphi for PHP product:
1 - See note above, download and install the Advantage PHP client.
2 - Copy the following files to the Delphi for PHP\X.X\php\ext directory:
ace32.dll
axcws32.dll
adsloc32.dll
php_advantage.dll (rename the existing php_advantage.dll.5.x.x file)
3 - Add the following line to the Delphi for PHP\X.X\php\php.ini.template file:
extension=php_advantage.dll
4 - To use: enter "ads" as the DriverName on a connection component, and set
a Host property similar to "DataDirectory=c:\". See the Advantage PHP
help file topic for ads_connect for details on connection path options
and formatting.
5 - (optional) - Modify the Delphi for PHP\X.X\vcl\packages\database.packages.php
file and add ads to the list of strings returned when registering the
Database object's DriverName property.

This is a version of the ADODB driver for DB2. It uses the 'ibm_db2' PECL extension
for PHP (http://pecl.php.net/package/ibm_db2), which in turn requires DB2 V8.2.2 or
higher.
Originally tested with PHP 5.1.1 and Apache 2.0.55 on Windows XP SP2.
More recently tested with PHP 5.1.2 and Apache 2.0.55 on Windows XP SP2.
This file was ported from "adodb-odbc.inc.php" by Larry Menard, "larry.menard#rogers.com".
I ripped out what I believed to be a lot of redundant or obsolete code, but there are
probably still some remnants of the ODBC support in this file; I'm relying on reviewers
of this code to point out any other things that can be removed.

Revision 1: (02/25/2005) Updated codebase to include the _inject_bind_options function. This allows
users to access the options in the ldap_set_option function appropriately. Most importantly
LDAP Version 3 is now supported. See the examples for more information. Also fixed some minor
bugs that surfaced when PHP error levels were set high.

First cut at the Netezza Driver by Josh Eldridge joshuae74#hotmail.com
Based on the previous postgres drivers.
http://www.netezza.com/
Major Additions/Changes:
MetaDatabasesSQL, MetaTablesSQL, MetaColumnsSQL
Note: You have to have admin privileges to access the system tables
Removed non-working keys code (Netezza has no concept of keys)
Fixed the way data types and lengths are returned in MetaColumns()
as well as added the default lengths for certain types
Updated public variables for Netezza
Still need to remove blob functions, as Netezza doesn't suppport blob

Latest version is available at http://adodb.sourceforge.net
Portable version of oci8 driver, to make it more similar to other database drivers.
The main differences are
1. that the OCI_ASSOC names are in lowercase instead of uppercase.
2. bind variables are mapped using ? instead of :<bindvar>
Should some emulation of RecordCount() be implemented?

DB2 data driver. Requires ODBC.
From phpdb list:
Hi Andrew,
thanks a lot for your help. Today we discovered what
our real problem was:
After "playing" a little bit with the php-scripts that try
to connect to the IBM DB2, we set the optional parameter
Cursortype when calling odbc_pconnect(....).
And the exciting thing: When we set the cursor type
to SQL_CUR_USE_ODBC Cursor Type, then
the whole query speed up from 1 till 10 seconds
to 0.2 till 0.3 seconds for 100 records. Amazing!!!
Therfore, PHP is just almost fast as calling the DB2
from Servlets using JDBC (don't take too much care
about the speed at whole: the database was on a
completely other location, so the whole connection
was made over a slow network connection).
I hope this helps when other encounter the same
problem when trying to connect to DB2 from
PHP.
Kind regards,
Christian Szardenings
2 Oct 2001
Mark Newnham has discovered that the SQL_CUR_USE_ODBC is not supported by
IBM's DB2 ODBC driver, so this must be a 3rd party ODBC driver.
From the IBM CLI Reference:
SQL_ATTR_ODBC_CURSORS (DB2 CLI v5)
This connection attribute is defined by ODBC, but is not supported by DB2
CLI. Any attempt to set or get this attribute will result in an SQLSTATE of
HYC00 (Driver not capable).
A 32-bit option specifying how the Driver Manager uses the ODBC cursor
library.
So I guess this means the message [above] was related to using a 3rd party
odbc driver.
Setting SQL_CUR_USE_ODBC
========================
To set SQL_CUR_USE_ODBC for drivers that require it, do this:
$db = NewADOConnection('odbc_db2');
$db->curMode = SQL_CUR_USE_ODBC;
$db->Connect($dsn, $userid, $pwd);
USING CLI INTERFACE
===================
I have had reports that the $host and $database params have to be reversed in
Connect() when using the CLI interface. From Halmai Csongor csongor.halmai#nexum.hu:
> The symptom is that if I change the database engine from postgres or any other to DB2 then the following
> connection command becomes wrong despite being described this version to be correct in the docs.
>
> $connection_object->Connect( $DATABASE_HOST, $DATABASE_AUTH_USER_NAME, $DATABASE_AUTH_PASSWORD, $DATABASE_NAME )
>
> In case of DB2 I had to swap the first and last arguments in order to connect properly.
System Error 5
==============
IF you get a System Error 5 when trying to Connect/Load, it could be a permission problem. Give the user connecting
to DB2 full rights to the DB2 SQLLIB directory, and place the user in the DBUSERS group.

Latest version is available at http://adodb.sourceforge.net
21.02.2002 - Wade Johnson wade@wadejohnson.de
Extended ODBC class for Sybase SQLAnywhere.
1) Added support to retrieve the last row insert ID on tables with
primary key column using autoincrement function.
2) Added blob support. Usage:
a) create blob variable on db server:
$dbconn->create_blobvar($blobVarName);
b) load blob var from file. $filename must be complete path
$dbcon->load_blobvar_from_file($blobVarName, $filename);
c) Use the $blobVarName in SQL insert or update statement in the values
clause:
$recordSet = $dbconn->Execute('INSERT INTO tabname (idcol, blobcol) '
.
'VALUES (\'test\', ' . $blobVarName . ')');
instead of loading blob from a file, you can also load from
an unformatted (raw) blob variable:
$dbcon->load_blobvar_from_var($blobVarName, $varName);
d) drop blob variable on db server to free up resources:
$dbconn->drop_blobvar($blobVarName);
