<h2>Introduction<a name=intro></a></h2>
|
|||
|
|
|
|||
|
|
<p>PHP's database access functions are not standardised. This creates a need
|
|||
|
|
for a database class library to hide the differences between the different
|
|||
|
|
database API's (encapsulate the differences) so we can easily switch databases.
|
|||
|
|
PHP 4.0.5 or later is now required (because we use array-based str_replace).</p>
|
|||
|
|
|
|||
|
|
<p>We currently support MySQL, Oracle, Microsoft SQL Server, Sybase, Sybase SQL
|
|||
|
|
Anywhere, Informix, PostgreSQL, FrontBase, SQLite, Interbase (Firebird and
|
|||
|
|
Borland variants), Foxpro, Access, <st1:City w:st="on"><st1:place w:st="on">ADO</st1:place></st1:City>,
|
|||
|
|
DB2, SAP DB and ODBC. We have had successful reports of connecting to Progress
|
|||
|
|
and CacheLite via ODBC. We hope more people will contribute drivers to support
|
|||
|
|
other databases.</p>
|
|||
|
|
|
|||
|
|
<p>PHP4 supports session variables. You can store your session information
|
|||
|
|
using ADOdb for true portability and scalability. See adodb-session.php for
|
|||
|
|
more information.</p>
|
|||
|
|
|
|||
|
|
<p>Also read <a href="http://phplens.com/lens/adodb/tips_portable_sql.htm">tips_portable_sql.htm</a>
|

<h3>Code Initialization Examples<a name=coding></a></h3>
|
|||
|
|
|
|||
|
|
<p>When running ADOdb, at least two files are loaded. First is
|
|||
|
|
adodb/adodb.inc.php, which contains all functions used by all database classes.
|
|||
|
|
The code specific to a particular database is in the
|
|||
|
|
adodb/driver/adodb-????.inc.php file.</p>
|
|||
|
|
|
|||
|
|
<p><a name=adonewconnection></a>For example, to connect to a mysql database:</p>
|
|||
|
|
|
|||
|
|
<div style='mso-element:para-border-div;border:solid #DDDDDD 1.0pt;mso-border-alt:
|
|||
|
|
solid #DDDDDD .75pt;padding:9.0pt 18.0pt 9.0pt 18.0pt;background:#EEEEEE'><pre
|
|||
|
|
style='background:#EEEEEE'>include('/path/to/set/here/adodb.inc.php');<br>
|
|||
|
|
$conn = &ADONewConnection('mysql');</pre></div>
|
|||
|
|
|
|||
|
|
<p>Whenever you need to connect to a database, you create a Connection object
|
|||
|
|
using the <b>ADONewConnection</b>($driver) function. <b>NewADOConnection</b>($driver)
|
|||
|
|
is an alternative name for the same function.</p>
|
|||
|
|
|
|||
|
|
<p>At this point, you are not connected to the database (no longer true if you
|
|||
|
|
pass in a <a href="#dsnsupport">dsn</a>). You will first need to decide whether
|
|||
|
|
to use <i>persistent</i> or <i>non-persistent</i> connections. The advantage of
|
|||
|
|
<i>persistent</i> connections is that they are faster, as the database
|
|||
|
|
connection is never closed (even when you call Close()). <i>Non-persistent </i>connections
|
|||
|
|
take up much fewer resources though, reducing the risk of your database and
|
|||
|
|
your web-server becoming overloaded. </p>
|
|||
|
|
|
|||
|
|
<p>For persistent connections, use $conn-><a href="#pconnect">PConnect()</a>,
|
|||
|
|
or $conn-><a href="#connect">Connect()</a> for non-persistent connections.
|
|||
|
|
Some database drivers also support <a href="#nconnect">NConnect()</a>, which
|
|||
|
|
forces the creation of a new connection. <a name="connection_gotcha"></a></p>
|
|||
|
|
|
|||
|
|
<p><b>Connection Gotcha</b>: If you create two connections, but both use the
|
|||
|
|
same userid and password, PHP will share the same connection. This can cause
|
|||
|
|
problems if the connections are meant to different databases. The solution is
|
|||
|
|
to always use different userid's for different databases, or use NConnect(). <a
|
|||
|
|
name=dsnsupport></a></p>
|
|||
|
|
|
|||
|
|
<h3>Data Source Name (DSN) Support</h3>
|
|||
|
|
|
|||
|
|
<p>Since ADOdb 4.51, you can connect to a database by passing a dsn to
|
|||
|
|
NewADOConnection() (or ADONewConnection, which is the same function). The dsn
|
|||
|
|
format is: </p>
|
|||
|
|
|
|||
|
|
<div style='mso-element:para-border-div;border:solid #DDDDDD 1.0pt;mso-border-alt:

|
|||
|
|
|
|||
|
|
<p>NewADOConnection() calls Connect() or PConnect() internally for you. If the
|
|||
|
|
connection fails, false is returned. </p>

set, a persistent connection is forced; similarly, when <i>new</i> is set, then

a new connection will be created using NConnect if the underlying driver

supports it. The <i>debug</i> option enables debugging. The <i>fetchmode</i>

<h2><a name=speed></a>High Speed ADOdb - tuning tips</h2>
|

|
|
<p>ADOdb is a big class library, yet it <a href="http://phplens.com/lens/adodb/">consistently
|
|||
|
|
beats</a> all other PHP class libraries in performance. This is because it is
|
|||
|
|
designed in a layered fashion, like an onion, with the fastest functions in the
|
|||
|
|
innermost layer. Stick to the following functions for best performance:</p>

</div>
|
|||
|
|
|
|||
|
|
<p>The fastest way to access the field data is by accessing the array
|
|||
|
|
$recordset->fields directly. Also set the global variables <a
|
|||
|
|
href="#adodb_fetch_mode">$ADODB_FETCH_MODE</a> = ADODB_FETCH_NUM, and (for
|
|||
|
|
oci8, ibase/firebird and odbc) <a href="#adodb_countrecs">$ADODB_COUNTRECS</a>
|
|||
|
|
= false before you connect to your database.</p>
|
|||
|
|
|
|||
|
|
<p>Consider using bind parameters if your database supports it, as it improves
|
|||
|
|
query plan reuse. Use ADOdb's performance tuning system to identify bottlenecks
|
|||
|
|
quickly. At the time of writing (Dec 2003), this means oci8 and odbc drivers.</p>
|
|||
|
|
|
|||
|
|
<p>Lastly make sure you have a PHP accelerator cache installed such as APC,
|
|||
|
|
Turck MMCache, Zend Accelerator or ionCube.</p>

<p><b>Advanced Tips</b> </p>
|
|||
|
|
|
|||
|
|
<p>If you have the <a href="http://adodb.sourceforge.net/#extension">ADOdb C
|
|||
|
|
extension</a> installed, you can replace your calls to $rs->MoveNext() with
|
|||
|
|
adodb_movenext($rs). This doubles the speed of this operation. For retrieving
|
|||
|
|
entire recordsets at once, use GetArray(), which uses the high speed extension
|
|||
|
|
function adodb_getall($rs) internally. </p>
|
|||
|
|
|
|||
|
|
<p>Execute() is the default way to run queries. You can use the low-level
|
|||
|
|
functions _Execute() and _query() to reduce query overhead. Both these
|
|||
|
|
functions share the same parameters as Execute(). </p>
|
|||
|
|
|
|||
|
|
<p>If you do not have any bind parameters or your database supports binding
|
|||
|
|
(without emulation), then you can call _Execute() directly. Calling this
|
|||
|
|
function bypasses bind emulation. Debugging is still supported in _Execute(). </p>
|
|||
|
|
|
|||
|
|
<p>If you do not require debugging facilities nor emulated binding, and do not
|
|||
|
|
require a recordset to be returned, then you can call _query. This is great for
|
|||
|
|
inserts, updates and deletes. Calling this function bypasses emulated binding,
|
|||
|
|
debugging, and recordset handling. Either the resultid, true or false are
|
|||
|
|
returned by _query(). </p>
|
|||
|
|
|
|||
|
|
<p>For Informix, you can disable scrollable cursors with $db->cursorType =
|
|||
|
|
0. </p>
|
|||
|
|
|
|||
|
|
<h2><a name=hack></a>Hacking ADOdb Safely</h2>
|
|||
|
|
|
|||
|
|
<p>You might want to modify ADOdb for your own purposes. Luckily you can still
|
|||
|
|
maintain backward compatibility by sub-classing ADOdb and using the
|
|||
|
|
$ADODB_NEWCONNECTION variable. $ADODB_NEWCONNECTION allows you to override the
|
|||
|
|
behaviour of ADONewConnection(). ADOConnection() checks for this variable and
|
|||
|
|
will call the function-name stored in this variable if it is defined. </p>
|
|||
|
|
|
|||
|
|
<p>In the following example, new functionality for the connection object is
|
|||
|
|
placed in the <i>hack_mysql</i> and <i>hack_postgres7</i> classes. The
|
|||
|
|
recordset class naming convention can be controlled using $rsPrefix. Here we
|
|||
|
|
set it to 'hack_rs_', which will make ADOdb use <i>hack_rs_mysql</i> and <i>hack_rs_postgres7</i>
|
|||
|
|
as the recordset classes. </p>

<p>The "Tested" column indicates how extensively the code has been
|

|
|
tested and used. <br>
|
|||
|
|
A = well tested and used by many people<br>
|
|||
|

B = tested and usable, but some features might not be implemented<br>
|

latest features of ADOdb. </p>

<p>The column "RecordCount() usable" indicates whether RecordCount()
|
|||
|
|
return the number of rows, or returns -1 when a SELECT statement is executed.
|
|||
|
|
If this column displays Y/N then the RecordCount() is emulated when the global
|
|||
|
|
variable $ADODB_COUNTRECS=true (this is the default). Note that for large
|
|||
|
|
recordsets, it might be better to disable RecordCount() emulation because
|
|||
|
|
substantial amounts of memory are required to cache the recordset for counting.
|
|||
|
|
Also there is a speed penalty of 40-50% if emulation is required. This is
|
|||
|
|
emulated in most databases except for PostgreSQL and MySQL. This variable is
|
|||
|
|
checked every time a query is executed, so you can selectively choose which
|
|||
|
|
recordsets to count.</p>

|
<p>Task: Connect to the Access Northwind DSN, display the first 2 columns of
|
|||
|
|
each row.</p>
|
|||
|
|
|
|||
|
|
<p>In this example, we create a ADOConnection object, which represents the
|
|||
|
|
connection to the database. The connection is initiated with <a href="#pconnect"><span
|
|||
|
|
style='font-family:"Courier New"'>PConnect</span></a>, which is a persistent
|
|||
|
|
connection. Whenever we want to query the database, we call the <span
|
|||
|
|
style='font-family:"Courier New"'>ADOConnection.<a href="#execute">Execute</a>()</span>
|
|||
|
|
function. This returns an ADORecordSet object which is actually a cursor that
|
|||
|
|
holds the current row in the array <span style='font-family:"Courier New"'>fields[]</span>.
|
|||
|
|
We use <span style='font-family:"Courier New"'><a href="#movenext">MoveNext</a>()</span>
|
|||
|
|
to move from row to row.</p>
|
|||
|
|
|
|||
|
|
<p>NB: A useful function that is not used in this example is <span
|
|||
|
|
style='font-family:"Courier New"'><a href="#selectlimit">SelectLimit</a></span>,
|
|||
|
|
which allows us to limit the number of rows shown. </p>

|
<p>The <code><span style='font-size:10.0pt'>$recordSet->fields[]</span></code>
|
|||
|
|
array is generated by the PHP database extension. Some database extensions only
|
|||
|
|
index by number and do not index the array by field name. To force indexing by
|
|||
|
|
name - that is associative arrays - use the SetFetchMode function. Each
|
|||
|
|
recordset saves and uses whatever fetch mode was set when the recordset was
|
|||
|
|
created in Execute() or SelectLimit(). </p>

|
<p>ADOdb 1.31 and later supports two new recordset functions: GetUpdateSQL( )
|
|||
|
|
and GetInsertSQL( ). This allow you to perform a "SELECT * FROM table
|
|||
|
|
query WHERE...", make a copy of the $rs->fields, modify the fields, and
|
|||
|
|
then generate the SQL to update or insert into the table automatically. </p>
|
|||
|
|
|
|||
|
|
<p>We show how the functions can be used when accessing a table with the
|
|||
|
|
following fields: (ID, FirstName, LastName, Created). </p>
|
|||
|
|
|
|||
|
|
<p>Before these functions can be called, you need to initialize the recordset by
|
|||
|
|
performing a select on the table. Idea and code by Jonathan Younger
|
|||
|
|
jyounger#unilab.com. Since ADOdb 2.42, you can pass a table name instead of a
|
|||
|
|
recordset into GetInsertSQL (in $rs), and it will generate an insert statement
|
|||
|
|
for that table. </p>

included with this release, and the class ADODB_Pager in <i>adodb/adodb-pager.inc.php</i>.
|

The ADODB_Pager code can be adapted by a programmer so that the text links can
|

be replaced by images, and the dull white background be replaced with more

interesting colors. </p>

<p>ADOdb also provides two custom handlers which you can modify for your needs.
|
|||
|
|
The first one is in the <b>adodb-errorhandler.inc.php</b> file. This makes use
|
|||
|
|
of the standard PHP functions <a href="http://php.net/error_reporting">error_reporting</a>
|
|||
|
|
to control what error messages types to display, and <a
|
|||
|
|
href="http://php.net/trigger_error">trigger_error</a> which invokes the default
|
|||
|
|
PHP error handler. </p>
|
|||
|
|
|
|||
|
|
<p>Including the above file will cause <i>trigger_error($errorstring,E_USER_ERROR)</i>
|
|||
|
|
to be called when<br>
|
|||
|
|
(a) Connect() or PConnect() fails, or <br>
|
|||
|
|
(b) a function that executes SQL statements such as Execute() or SelectLimit()
|
|||
|
|
has an error.<br>
|
|||
|
|
(c) GenID() appears to go into an infinite loop. </p>
|
|||
|
|
|
|||
|
|
<p>The $errorstring is generated by ADOdb and will contain useful debugging
|
|||
|
|
information similar to the error.log data generated below. This file
|
|||
|
|
adodb-errorhandler.inc.php should be included before you create any
|
|||
|
|
ADOConnection objects. </p>
|
|||
|
|
|
|||
|
|
<p>If you define error_reporting(0), no errors will be passed to the error
|
|||
|
|
handler. If you set error_reporting(E_ALL), all errors will be passed to the
|
|||
|
|
error handler. You still need to use <b>ini_set("display_errors",
|
|||
|
|
"0" or "1")</b> to control the display of errors. </p>

<p>You can use a PEAR_Error derived class by defining the constant

ADODB_PEAR_ERROR_CLASS before the adodb-errorpear.inc.php file is included. For

easy debugging, you can set the default error handler in the beginning of the

then halt script execution: </p>

<p>Note that we do not explicitly return a PEAR_Error object to you when an

<h3>MetaError and MetaErrMsg</h3>
|
|||
|
|
|
|||
|
|
<p>If you need error messages that work across multiple databases, then use <a
|
|||
|
|
href="#metaerror">MetaError()</a>, which returns a virtualized error number,
|
|||
|
|
based on PEAR DB's error number system, and <a href="#metaerrmsg">MetaErrMsg()</a>.

<h4>Error Messages</h4>
|
|||
|
|
|
|||
|
|
<p>Error messages are outputted using the static method
|
|||
|
|
ADOConnnection::outp($msg,$newline=true). By default, it sends the messages to
|
|||
|
|
the client. You can override this to perform error-logging. </p>

<h2><a name=caching></a>Caching of Recordsets</h2>
|
|||
|
|
|
|||
|
|
<p>ADOdb now supports caching of recordsets in the file system using the
|
|||
|
|
CacheExecute( ), CachePageExecute( ) and CacheSelectLimit( ) functions. There
|
|||
|
|
are similar to the non-cache functions, except that they take a new first
|
|||
|
|
parameter, $secs2cache. </p>
|
|||

|
|

|
|
|

|
|
<p>The first parameter is the number of seconds to cache the query. Subsequent
|
|||
|
|
calls to that query will used the cached version stored in $ADODB_CACHE_DIR. To
|
|||
|
|
force a query to execute and flush the cache, call CacheExecute() with the
|
|||
|
|
first parameter set to zero. Alternatively, use the CacheFlush($sql) call. </p>

|

<p>For the sake of security, we recommend you set <i>register_globals=off</i> in

<p>In ADOdb 1.80 onwards, the secs2cache parameter is optional in
|

CacheSelectLimit() and CacheExecute(). If you leave it out, it will use the

$connection->cacheSecs parameter, which defaults to 60 minutes. The following

|
|
are equivalent: </p>

<h2><a name=pivot></a>Pivot Tables</h2>
|
|||
|
|
|
|||
|
|
<p>Since ADOdb 2.30, we support the generation of SQL to create pivot tables,
|
|||
|
|
also known as cross-tabulations. For further explanation read this DevShed <a
|
|||
|
|
href="http://www.devshed.com/Server_Side/MySQL/MySQLWiz/">Cross-Tabulation tutorial</a>.
|
|||
|
|
We assume that your database supports the SQL case-when expression. </p>
|
|||
|
|
|
|||
|
|
<p>In this example, we will use the Northwind database from Microsoft. In the
|
|||
|
|
database, we have a products table, and we want to analyze this table by <i>suppliers
|
|||
|
|
versus product categories</i>. We will place the suppliers on each row, and
|
|||
|
|
pivot on categories. So from the table on the left, we generate the pivot-table
|
|||
|
|
on the right:</p>

<h2>Global Variables</h2>
|
|||
|
|
|
|||
|
|
<h3><a name="adodb_countrecs"></a>$ADODB_COUNTRECS</h3>
|
|||
|
|
|
|||
|
|
<p>If the database driver API does not support counting the number of records
|
|||
|
|
returned in a SELECT statement, the function RecordCount() is emulated when the
|
|||
|
|
global variable $ADODB_COUNTRECS is set to true, which is the default. We
|
|||
|
|
emulate this by buffering the records, which can take up large amounts of
|
|||
|
|
memory for big recordsets. Set this variable to false for the best performance.
|
|||
|
|
This variable is checked every time a query is executed, so you can selectively
|
|||
|
|
choose which recordsets to count.</p>
|
|||
|
|
|
|||
|
|
<h3><a name="adodb_cache_dir"></a>$ADODB_CACHE_DIR</h3>
|
|||
|
|
|
|||
|
|
<p>If you are using recordset caching, this is the directory to save your
|
|||
|
|
recordsets in. Define this before you call any caching functions such as
|
|||
|
|
CacheExecute( ). We recommend setting <i>register_globals=off</i> in php.ini if
|
|||
|
|
you use this feature for security reasons.</p>
|
|||
|
|
|
|||
|
|
<p>If you are using Unix and apache, you might need to set your cache directory
|
|||
|
|
permissions to something similar to the following:</p>
|
|||
|
|
|
|||
|
|
<p>chown -R apache /path/to/adodb/cache<br>
|
|||
|
|
chgrp -R apache /path/to/adodb/cache </p>
|
|||
|
|
|
|||
|
|
<h3><a name="adodb_ansi_padding_off"></a>$ADODB_ANSI_PADDING_OFF</h3>
|
|||
|
|
|
|||
|
|
<p>Determines whether to right trim CHAR fields (and also VARCHAR for
|
|||
|
|
ibase/firebird). Set to true to trim. Default is false. Currently works for
|
|||
|
|
oci8po, ibase and firebird drivers. Added in ADOdb 4.01. </p>
|
|||
|
|
|
|||
|
|
<h3><a name="adodb_lang"></a>$ADODB_LANG</h3>
|
|||
|
|
|
|||
|
|
<p>Determines the language used in MetaErrorMsg(). The default is 'en', for
|
|||
|
|
English. To find out what languages are supported, see the files in
|
|||
|
|
adodb/lang/adodb-$lang.inc.php, where $lang is the supported langauge. </p>
|
|||
|
|
|
|||
|
|
<h3><a name="adodb_fetch_mode"></a>$ADODB_FETCH_MODE</h3>
|
|||
|
|
|
|||
|
|
<p>This is a global variable that determines how arrays are retrieved by recordsets.
|
|||
|
|
The recordset saves this value on creation (eg. in Execute( ) or SelectLimit(
|
|||
|
|
)), and any subsequent changes to $ADODB_FETCH_MODE have no affect on existing
|
|||
|
|
recordsets, only on recordsets created in the future.</p>
|
|||
|
|
|
|||
|
|
<p>The following constants are defined:</p>
|
|||
|
|
|
|||
|
|
<p>define('ADODB_FETCH_DEFAULT',0);<br>
|
|||
|
|
define('ADODB_FETCH_NUM',1);<br>
|
|||
|
|
define('ADODB_FETCH_ASSOC',2);<br>
|
|||
|
|
define('ADODB_FETCH_BOTH',3); </p>

|||

|
<span style='mso-tab-count:1'><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> </span>$rs2 = $db->Execute('select * from table');<br>
|
|||
|
|
<span style='mso-tab-count:1'><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> </span>print_r($rs1->fields); # shows <i>array([0]=>'v0',[1] =>'v1')</i></pre><pre><span

|
|||
|
|
|
|||
|
|
<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>
|
|||
|
|
|
|||
|
|
<p>If no fetch mode is predefined, the fetch mode defaults to
|
|||
|
|
ADODB_FETCH_DEFAULT. The behaviour of this default mode varies from driver to
|
|||
|
|
driver, so do not rely on ADODB_FETCH_DEFAULT. For portability, we recommend
|
|||
|
|
sticking to ADODB_FETCH_NUM or ADODB_FETCH_ASSOC. Many drivers do not support
|
|||
|
|
ADODB_FETCH_BOTH.</p>
|
|||
|
|
|
|||
|
|
<p><strong>SetFetchMode Function</strong></p>
|
|||
|
|
|
|||
|
|
<p>If you have multiple connection objects, and want to have different fetch
|
|||
|
|
modes for each connection, then use <a href="#setfetchmode">SetFetchMode</a>.
|
|||
|
|
Once this function is called for a connection object, that connection object
|
|||
|
|
will ignore the global variable $ADODB_FETCH_MODE and will use the internal
|
|||
|
|
fetchMode property exclusively.</p>

<p><a name="adodb_assoc_case"></a><strong>ADODB_ASSOC_CASE</strong></p>
|
|||
|
|
|
|||
|
|
<p>You can control the associative fetch case for certain drivers which behave
|
|||
|
|
differently. For the sybase, oci8po, mssql, odbc and ibase drivers and all
|
|||
|
|
drivers derived from them, ADODB_ASSOC_CASE will by default generate recordsets
|
|||
|
|
where the field name keys are lower-cased. Use the constant ADODB_ASSOC_CASE to
|
|||
|
|
change the case of the keys. There are 3 possible values:</p>
|
|||
|
|
|
|||
|
|
<p>0 = assoc lowercase field names. $rs->fields['orderid']<br>
|
|||
|
|
1 = assoc uppercase field names. $rs->fields['ORDERID']<br>
|
|||
|
|
2 = use native-case field names. $rs->fields['OrderID'] -- this is the
|
|||
|
|
default since ADOdb 2.90</p>
|
|||
|
|
|
|||
|
|
<p>To use it, declare it before you incldue adodb.inc.php.</p>
|
|||
|
|
|
|||
|
|
<p>define('ADODB_ASSOC_CASE', 2); # use native-case for ADODB_FETCH_ASSOC<br>

|
|
|

|
|
<p><b>ADOConnection( )</b></p>
|
|||
|
|
|
|||
|
|
<p>Constructor function. Do not call this directly. Use ADONewConnection( )
|
|||
|
|
instead.</p>
|
|||
|
|
|
|||
|
|
<p><b>Connect<a name=connect></a>($host,[$user],[$password],[$database])</b></p>
|
|||
|
|
|
|||
|
|
<p>Non-persistent connect to data source or server $<b>host</b>, using userid $<b>user
|
|||
|
|
</b>and password $<b>password</b>. If the server supports multiple databases,
|
|||
|
|
connect to database $<b>database</b>. </p>
|
|||
|
|
|
|||
|
|
<p>Returns true/false depending on connection success. Since 4.23, null is
|
|||
|
|
returned if the extension is not loaded.</p>
|
|||
|
|
|
|||
|
|
<p><st1:City w:st="on"><st1:place w:st="on">ADO</st1:place></st1:City> Note: If
|
|||
|
|
you are using a Microsoft ADO and not OLEDB, you can set the $database
|
|||
|
|
parameter to the OLEDB data provider you are using.</p>
|
|||
|
|
|
|||
|
|
<p>PostgreSQL: An alternative way of connecting to the database is to pass the
|
|||
|
|
standard PostgreSQL connection string in the first parameter $host, and the
|
|||
|
|
other parameters will be ignored.</p>
|
|||
|
|
|
|||
|
|
<p>For Oracle and Oci8, there are two ways to connect. First is to use the TNS
|
|||
|
|
name defined in your local tnsnames.ora (or ONAMES or HOSTNAMES). Place the
|
|||
|
|
name in the $database field, and set the $host field to false. Alternatively,
|
|||
|
|
set $host to the server, and $database to the database SID, this bypassed
|
|||
|
|
tnsnames.ora. </p>
|
|||

|
|
|||

<p>There are many examples of connecting to a database. See <a
|
|||
|
|
href="#connect_ex">Connection Examples</a> for many examples. </p>
|
|||
|
|
|
|||
|
|
<p><b>PConnect<a name=pconnect></a>($host,[$user],[$password],[$database])</b></p>
|
|||
|
|
|
|||
|
|
<p>Persistent connect to data source or server $<b>host</b>, using userid $<b>user</b>
|
|||
|
|
and password $<b>password</b>. If the server supports multiple databases,
|
|||
|
|
connect to database $<b>database</b>.</p>
|
|||
|
|
|
|||
|
|
<p>We now perform a rollback on persistent connection for selected databases
|
|||
|
|
since 2.21, as advised in the PHP manual. See change log or source code for
|
|||
|
|
which databases are affected. </p>
|
|||
|
|
|
|||
|
|
<p>Returns true/false depending on connection. Since 4.23, 0 is returned if the
|
|||
|
|
extension is not loaded. See Connect( ) above for more info.</p>
|
|||
|
|
|
|||
|
|
<p>Since ADOdb 2.21, we also support autoRollback. If you set:</p>
|
|||
|
|
|
|||
|
|
<div style='mso-element:para-border-div;border:solid #DDDDDD 1.0pt;mso-border-alt:
|
|||
|
|
solid #DDDDDD .75pt;padding:9.0pt 18.0pt 9.0pt 18.0pt;background:#EEEEEE'><pre
|
|||
|
|
style='background:#EEEEEE'><span style='mso-spacerun:yes'><EFBFBD></span>$conn = &NewADOConnection('mysql');<br>
|
|||
|
|
<span style='mso-spacerun:yes'><EFBFBD></span>$conn->autoRollback = true; # default is false<br>
|
|||
|
|
<span style='mso-spacerun:yes'><EFBFBD></span>$conn->PConnect(...); # rollback here</pre></div>
|
|||
|
|
|
|||
|
|
<p>Then when doing a persistent connection with PConnect( ), ADOdb will perform
|
|||
|
|
a rollback first. This is because it is documented that PHP is not guaranteed
|
|||
|
|
to rollback existing failed transactions when persistent connections are used.
|
|||
|
|
This is implemented in Oracle, MySQL, PgSQL, MSSQL, ODBC currently. </p>
|
|||
|
|
|
|||
|
|
<p>Since ADOdb 3.11, you can force non-persistent connections even if PConnect
|
|||
|
|
is called by defining the constant ADODB_NEVER_PERSIST before you call
|
|||
|
|
PConnect. </p>
|
|||
|
|
|
|||
|
|
<p>Since 4.23, null is returned if the extension is not loaded. </p>
|
|||
|
|
|
|||
|
|
<p><b>NConnect<a name=nconnect></a>($host,[$user],[$password],[$database])</b></p>
|
|||
|
|
|
|||
|
|
<p>Always force a new connection. In contrast, PHP sometimes reuses connections
|
|||
|
|
when you use Connect() or PConnect(). Currently works only on mysql (PHP 4.3.0
|
|||
|
|
or later), postgresql and oci8-derived drivers. For other drivers, NConnect()
|
|||
|
|
works like Connect().</p>
|
|||
|
|
|
|||
|
|
<p><b>IsConnected( )</b><a name=isconnected></a></p>
|
|||
|
|
|
|||
|
|
<p>Returns true if connected to database. Added in 4.53. </p>
|
|||
|
|
|
|||
|
|
<p><b>Execute<a name=execute></a>($sql,$inputarr=false)</b></p>
|
|||
|
|
|
|||
|
|
<p>Execute SQL statement $<b>sql</b> and return derived class of ADORecordSet
|
|||
|
|
if successful. Note that a record set is always returned on success, even if we
|
|||
|
|
are executing an insert or update statement. You can also pass in $sql a
|
|||
|
|
statement prepared in <a href="#prepare">Prepare()</a>.</p>
|
|||
|
|
|
|||
|
|
<p>Returns derived class of ADORecordSet. Eg. if connecting via mysql, then
|
|||
|
|
ADORecordSet_mysql would be returned. False is returned if there was an error
|
|||
|
|
in executing the sql.</p>
|
|||
|
|
|
|||
|
|
<p>The $inputarr parameter can be used for binding variables to parameters.
|
|||
|
|
Below is an Oracle example:</p>
|
|||
|
|
|
|||
|
|
<div style='mso-element:para-border-div;border:solid #DDDDDD 1.0pt;mso-border-alt:
|
|||
|
|
solid #DDDDDD .75pt;padding:9.0pt 18.0pt 9.0pt 18.0pt;background:#EEEEEE'><pre
|
|||
|
|
style='background:#EEEEEE'><span style='mso-spacerun:yes'><EFBFBD></span>$conn->Execute("SELECT * FROM TABLE WHERE COND=:val", array('val'=> $val));<br>
|
|||
|
|
<span style='mso-spacerun:yes'><EFBFBD></span></pre></div>
|
|||
|
|
|
|||
|
|
<p>Another example, using ODBC,which uses the ? convention:</p>
|
|||
|
|
|
|||
|
|
<div style='mso-element:para-border-div;border:solid #DDDDDD 1.0pt;mso-border-alt:
|
|||
|
|

|
|||
|
|
style='background:#EEEEEE'><span style='mso-spacerun:yes'><EFBFBD> </span>$conn->Execute("SELECT * FROM TABLE WHERE COND=?", array($val));</pre></div>
|
|||
|
|
|
|||
|
|
<p class=MsoNormal><a name=binding></a><i>Binding variables</i></p>
|
|||
|
|
|
|||
|
|
<p>Variable binding speeds the compilation and caching of SQL statements,
|
|||
|
|
leading to higher performance. Currently Oracle, Interbase and ODBC supports
|
|||
|
|
variable binding. Interbase/ODBC style ? binding is emulated in databases that
|
|||
|
|
do not support binding. Note that you do not have to quote strings if you use
|
|||
|
|
binding. </p>
|
|||
|
|
|
|||
|
|
<p>Variable binding in the odbc, interbase and oci8po drivers. </p>

<p class=MsoNormal><a name=bulkbind></a><i>Bulk binding</i> </p>
|
|||
|
|
|
|||
|
|
<p>Since ADOdb 3.80, we support bulk binding in Execute(), in which you pass in
|
|||
|
|
a 2-dimensional array to be bound to an INSERT/UPDATE or DELETE statement. And since ADOdb 5.11 this is
|
|||
|
|
disabled by default due to security issues. To enable, set $conn->bulkBind = true. </p>

<p>This provides very high performance as the SQL statement is prepared first.
|

The prepared statement is executed repeatedly for each array row until all rows

<p class=MsoNormal>If $secs2cache is omitted, we use the value in

CacheExecute() only with SELECT statements. </p>

|
|
|||
|
|
<p>Performance note: I have done some benchmarks and found that they vary so
|
|||
|
|
greatly that it's better to talk about when caching is of benefit. When your
|
|||
|
|
database server is <i>much slower </i>than your Web server or the database is <i>very
|
|||
|
|
overloaded </i>then ADOdb's caching is good because it reduces the load on your
|
|||
|
|
database server. If your database server is lightly loaded or much faster than
|
|||
|
|
your Web server, then caching could actually reduce performance. </p>

<p><b>SelectLimit<a name=selectlimit></a>($sql,$numrows=-1,$offset=-1,$inputarr=false)</b></p>
|
|||
|
|
|
|||
|
|
<p>Returns a recordset if successful. Returns false otherwise. Performs a
|
|||
|
|
select statement, simulating PostgreSQL's SELECT statement, LIMIT $numrows
|
|||
|
|
OFFSET $offset clause.</p>
|
|||
|
|
|
|||
|
|
<p>In PostgreSQL, SELECT * FROM TABLE LIMIT 3 will return the first 3 records
|
|||
|
|
only. The equivalent is <code><span style='font-size:10.0pt'>$connection->SelectLimit('SELECT
|
|||
|
|
* FROM TABLE',3)</span></code>. This functionality is simulated for databases
|
|||
|
|
that do not possess this feature.</p>
|
|||
|
|
|
|||
|
|
<p>And SELECT * FROM TABLE LIMIT 3 OFFSET 2 will return records 3, 4 and 5 (eg.
|
|||
|
|
after record 2, return 3 rows). The equivalent in ADOdb is <code><span
|
|||
|
|
style='font-size:10.0pt'>$connection->SelectLimit('SELECT * FROM TABLE',3,2)</span></code>.</p>
|
|||
|
|
|
|||
|
|
<p>Note that this is the <i>opposite</i> of MySQL's LIMIT clause. You can also
|
|||
|
|
set <code><span style='font-size:10.0pt'>$connection->SelectLimit('SELECT *
|
|||
|
|
FROM TABLE',-1,10)</span></code> to get rows 11 to the last row.</p>
|
|||
|
|
|
|||
|
|
<p>The last parameter $inputarr is for databases that support variable binding
|
|||
|
|
such as Oracle oci8. This substantially reduces SQL compilation overhead. Below

You might need to include adodb-error.inc.php before you call this function.
|

|
|
The parameter $errno is the native error number you want to convert. If you do

not pass any parameter, MetaError will call ErrorNo() for you and convert it.
|
|||
|
|

|
|
<p>This can return a string even if no error occurs. In general you do not need

|
|
to call this function unless an ADOdb function returns false on an error. </p>
|
|||
|
|

|
|
<p>Note: If <b>debug</b> is enabled, the SQL error message is always displayed

<p>Generate a sequence number . Works for interbase, mysql, postgresql, oci8,

|
|
oci8po, mssql, ODBC based (access,vfp,db2,etc) drivers currently. Uses $seqName
|

as the name of the sequence. GenID() will automatically create the sequence for
|

you if it does not exist (provided the userid has permission to do so).
|

|
|
Otherwise you will have to create the sequence yourself. </p>
|
|||
|
|
|

|
|
<p>If your database driver emulates sequences, the name of the table is the
|

|
|
sequence name. The table has one column, "id" which should be of type
|
|||
|
|
integer, or if you need something larger - numeric(16). </p>
|
|||
|
|
|
|||
|
|
<p>For ODBC and databases that do not support sequences natively (eg mssql,
|
|||
|
|
mysql), we create a table for each sequence. If the sequence has not been
|
|||
|
|
defined earlier, it is created with the starting value set in $startID.</p>

|

<p>Note that when an Interbase blob is retrieved using SELECT, it still needs

value in versions of PHP before 4.1.0. </p>
|

|
|
|
|||
|
|
<p>For PostgreSQL, you can store your blob using blob oid's or as a bytea field.
|
|||
|
|
You can use bytea fields but not blob oid's currently with UpdateBlob( ).
|

|
|
Conversely UpdateBlobFile( ) supports oid's, but not bytea data.<br>
|
|||
|
|
<br>

If you do not pass in an oid, then UpdateBlob() assumes that you are storing in

bytea fields. </p>

<p>Some databases require blob's to be encoded manually before upload. Note if

|
|
you use UpdateBlob( ) or UpdateBlobFile( ) the conversion is done automatically
|
|||
|
|
for you and you do not have to call this function. For PostgreSQL, currently,

BlobEncode() can only be used for bytea fields. </p>

|

|
|
|

<p>Note that there is a connection property called <em>blobEncodeType</em>
|
|||
|
|
which has 3 legal values: </p>
|
|||
|
|
|
|||
|
|
<p>false - no need to perform encoding or decoding.<br>
|
|||
|
|
'I' - blob encoding required, and returned encoded blob is a numeric value (no
|
|||
|
|
need to quote).<br>
|

|
|
'C' - blob encoding required, and returned encoded blob is a character value
|
|||
|
|
(requires quoting). </p>
|
|||
|
|
|
|||
|
|
<p>This is purely for documentation purposes, so that programs that accept
|
|||
|
|
multiple database drivers know what is the right thing to do when processing

blobs. </p>

</p>
|

|
|
|
|||
|
|
<p>Some databases require blob's to be decoded manually after doing a select
|
|||
|
|
statement. If the database does not require decoding, then this function will
|
|||
|
|
return the blob unchanged. Currently BlobDecode is only required for one
|
|||
|
|
database, PostgreSQL, and only if you are using blob oid's (if you are using
|
|||
|
|
bytea fields, we auto-decode for you). The default maxblobsize is set in
|
|||
|
|
$connection->maxblobsize, which is set to 256K in adodb 4.54. </p>
|
|||
|
|
|

<p>In ADOdb 4.54 and later, the blob is the return value. In earlier versions,

2 if no record was found and the insert was executed successfully. This differs

<p>Since ADOdb 4.56, you can automatically generate and execute INSERTs and

<p>AutoExecute() inserts or updates $table given an array of $arrFields, where

the keys are the field names and the array values are the field values to
|
|||
|

|

|
|
extract key information before the SQL is generated. We generate an INSERT or

<p>Note: One of the strengths of ADOdb's AutoExecute() is that only valid field
|
|||
|
|
names for $table are updated. If $arrFields contains keys that are invalid
|
|||
|
|
field names for $table, they are ignored. There is some overhead in doing this
|
|||
|
|
as we have to query the database to get the field names, but given that you are
|
|||
|
|
not directly coding the SQL yourself, you probably aren't interested in speed

at all, but convenience. </p>

<p>Since 4.62, the table name to be used can be overridden by setting

<p>Since 4.94, setting the global variable $ADODB_QUOTE_FIELDNAMES to true will

|

|
|
|
|||
|
|
<p>because you perform no error checking. It is possible to update table1 and
|
|||
|
|
for the update on table2 to fail. Here is a better way: </p>
|
|||
|
|
|
|||
|
|
<div style='mso-element:para-border-div;border:solid #DDDDDD 1.0pt;mso-border-alt:

|

|
|
if ($ok) $ok = $DB->Execute("update table2 set val=$val2 where id=$id");<br>
|
|||
|
|
if ($ok) $DB->CommitTrans();<br>
|
|||
|
|
else $DB->RollbackTrans();</pre></div>
|
|||
|
|
|
|||
|
|
<p>Another way is (since ADOdb 2.0): </p>
|
|||

|
|
<div style='mso-element:para-border-div;border:solid #DDDDDD 1.0pt;mso-border-alt:

|

|
|
|
|||
|
|
<p>Now it is a headache monitoring $ok all over the place. StartTrans() is an
|
|||
|
|
improvement because it monitors all SQL errors for you. This is particularly
|
|||
|
|
useful if you are calling black-box functions in which SQL queries might be
|
|||
|
|
executed. Also all BeginTrans, CommitTrans and RollbackTrans calls inside a
|
|||
|
|
StartTrans block will be disabled, so even if the black box function does a

|
|
commit, it will be ignored. </p>

<p><b>CompleteTrans<a name=completetrans></a>($autoComplete=true)</b></p>
|
|||
|
|
|
|||
|
|
<p>Complete a transaction called with StartTrans(). This function monitors for
|
|||
|
|
SQL errors, and will commit if no errors have occured, otherwise it will
|

|
|
rollback. Returns true on commit, false on rollback. If the parameter

$autoComplete is true monitor sql errors and commit and rollback as
|
|||
|
|
appropriate. Set $autoComplete to false to force rollback even if no SQL error

|
|
<p>Check whether smart transaction has failed, eg. returns true if there was an

<p>Begin a transaction. Turns off autoCommit. Returns true if successful. Some
|
|||
|
|
databases will always return false if transaction support is not available. Any
|
|||
|
|
open transactions will be rolled back when the connection is closed. Among the
|
|||
|
|
databases that support transactions are Oracle, PostgreSQL, Interbase, MSSQL,
|
|||
|
|
certain versions of MySQL, DB2, Informix, Sybase, etc.</p>
|
|||
|
|
|
|||
|
|
<p>Note that <a href="#starttrans">StartTrans()</a> and CompleteTrans() is a
|
|||
|
|
superior method of handling transactions, available since ADOdb 3.40. For a
|
|||
|
|
explanation, see the <a href="#starttrans">StartTrans()</a> documentation. </p>
|
|||
|
|
|
|||
|
|
<p>You can also use the ADOdb <a href="#errorhandling">error handler</a> to die
|
|||
|
|
and rollback your transactions for you transparently. Some buggy database
|
|||
|
|
extensions are known to commit all outstanding tranasactions, so you might want
|
|||
|
|
to explicitly do a $DB->RollbackTrans() in your error handler for safety. </p>
|
|||
|
|
|
|||
|
|
<h4>Detecting Transactions</h4>
|
|||
|
|
|
|||
|
|
<p>Since ADOdb 2.50, you are able to detect when you are inside a transaction.
|
|||
|
|
Check that $connection->transCnt > 0. This variable is incremented whenever
|
|||
|
|
BeginTrans() is called, and decremented whenever RollbackTrans() or
|
|||
|
|
CommitTrans() is called. </p>
|
|||
|
|
|
|||
|
|
<p><b>CommitTrans<a name=committrans></a>($ok=true)</b></p>
|
|||
|
|
|
|||
|
|
<p>End a transaction successfully. Returns true if successful. If the database
|
|||
|
|
does not support transactions, will return true also as data is always
|
|||
|
|
committed. </p>
|
|||
|
|
|
|||
|
|
<p>If you pass the parameter $ok=false, the data is rolled back. See example in
|
|||
|
|
BeginTrans().</p>
|
|||
|
|
|
|||
|
|
<p><b>RollbackTrans<a name=rollbacktrans></a>( )</b></p>
|
|||
|
|
|
|||
|
|
<p>End a transaction, rollback all changes. Returns true if successful. If the
|
|||
|
|
database does not support transactions, will return false as data is never
|
|||
|
|
rollbacked. </p>
|
|||
|
|
|
|||
|
|
<p><b>SetTransactionMode<a name=SetTransactionMode></a>($mode )</b></p>
|
|||
|
|
|
|||
|
|
<p>SetTransactionMode allows you to pass in the transaction mode to use for all
|
|||
|
|
subsequent transactions. Note: if you have persistent connections and using
|
|||
|
|
mssql or mysql, you might have to explicitly reset your transaction mode at the
|
|||
|
|
beginning of each page request. This is only supported in postgresql, mssql,
|
|||
|
|
mysql with InnoDB and oci8 currently. For example: </p>

<p>Returns an array containing the original sql statement in the first array

<p>Also see InParameter(), OutParameter() and PrepareSP() below. Only supported

|
emulated. There is no performance advantage to using Prepare() with emulation. </p>
|
|||
|
|
|
|||
|
|
<p>Important: Due to limitations or bugs in PHP, if you are getting errors when
|
|||
|
|
you using prepared queries, try setting $ADODB_COUNTRECS = false before
|
|||
|
|
preparing. This behaviour has been observed with ODBC. </p>

<br>
|
|||
|
|
$<b><i>stmt</i></b> Statement returned by Prepare() or PrepareSP().<br>
|
|||
|
|
$<b><i>var</i></b> PHP variable to bind to. Make sure you pre-initialize it!<br>
|
|||
|
|
$<b><i>name</i></b> Name of stored procedure variable name to bind to.<br>
|
|||
|
|
[$<b><i>isOutput</i></b>] Indicates direction of parameter 0/false=IN 1=OUT 2=

|

|

[$<b>maxLen</b>] Maximum length of the parameter variable.<br>

[$<b>type</b>] Consult <a href="http://php.net/mssql_bind">mssql_bind</a> and <a

|
<p>This is a low-level function supported only by the oci8 driver. <b>Avoid
|
|||
|
|
using</b> unless you only want to support Oracle. The Parameter( ) function is
|
|||
|
|
the recommended way to go with bind variables.</p>
|
|||
|
|
|
|||
|
|
<p>Bind( ) allows you to use bind variables in your sql statement. This binds a
|
|||
|
|
PHP variable to a name defined in an Oracle sql statement that was previously
|
|||
|
|
prepared using Prepare(). Oracle named variables begin with a colon, and ADOdb
|
|||
|
|
requires the named variables be called :0, :1, :2, :3, etc. The first
|
|||
|
|
invocation of Bind() will match :0, the second invocation will match :1, etc.
|
|||
|
|
Binding can provide 100% speedups for insert, select and update statements. </p>
|
|||
|
|
|
|||
|
|
<p>The other variables, $size sets the buffer size for data storage, $type is
|
|||
|
|
the optional descriptor type OCI_B_FILE (Binary-File), OCI_B_CFILE
|
|||
|
|
(Character-File), OCI_B_CLOB (Character-LOB), OCI_B_BLOB (Binary-LOB) and
|
|||
|
|
OCI_B_ROWID (ROWID). Lastly, instead of using the default :0, :1, etc names,
|
|||
|
|
you can define your own bind-name using $name. </p>
|
|||
|
|
|
|||
|
|
<p>The following example shows 3 bind variables being used: p1, p2 and p3.
|
|||
|
|
These variables are bound to :0, :1 and :2.</p>

logged. </p>

<p>If you prefer to use another name for the table used to store the SQL, you

can override it by calling adodb_perf::table($tablename), where $tablename is

the new table name (you will still need to manually create the table yourself).

<p>The fnExecute function is called before the sql is parsed and executed, so
|
|||
|
|
you can perform a query rewrite. If you are passing in a prepared statement,
|
|||
|
|
then $sql is an array (see <a href="#prepare">Prepare</a>). The fnCacheExecute
|
|||
|
|
function is only called if the recordset returned was cached. The function
|
|||
|
|
parameters match the Execute and CacheExecute functions respectively, except
|
|||
|
|
that $this (the connection object) is passed as the first parameter.</p>
|
|||
|
|
|
|||
|
|
<p>Since ADOdb 3.91, the behaviour of fnExecute varies depending on whether the
|
|||
|
|
defined function returns a value. If it does not return a value, then the $sql
|
|||
|
|
is executed as before. This is useful for query rewriting or counting sql
|
|||
|
|
queries. </p>
|
|||
|
|
|
|||
|
|
<p>On the other hand, you might want to replace the Execute function with one
|
|||
|
|
of your own design. If this is the case, then have your function return a
|
|||
|
|
value. If a value is returned, that value is returned immediately, without any
|
|||
|
|
further processing. This is used internally by ADOdb to implement LogSQL()
|
|||
|
|
functionality. </p>

<p><b>Concat<a name=concat></a>($s1,$s2,....)</b></p>
|
|||
|
|
|
|||
|
|
<p>Generates the sql string used to concatenate $s1, $s2, etc together. Uses
|
|||
|
|
the string in the concat_operator field to generate the concatenation. Override
|
|||
|
|
this function if a concatenation operator is not used, eg. MySQL.</p>
|

|
|
|

<p>Returns the concatenated string.</p>

<p><b>DBDate<a name=dbdate></a>($date)</b></p>
|
|||
|
|
|
|||
|
|
<p>Format the $<b>date</b> in the format the database accepts - the return
|
|||
|
|
string is also quoted. This is used when you are sending dates to the database
|
|||
|
|
(eg INSERT, UPDATE or where clause of SELECT statement). The $<b>date</b>
|
|||
|
|
parameter can be a PHP DateTime object (since ADOdb 5.09), a Unix integer timestamp or an ISO format Y-m-d. Uses the
|
|||
|
|
fmtDate field, which holds the format to use. If null or false or '' is passed
|
|||
|
|
in, it will be converted to an SQL null.</p>
|
|||
|
|
|

<p>Returns the date as a quoted string.</p>

<p><b>MetaDatabases<a name=metadatabases></a>()</b></p>
|
|||
|
|
|
|||
|
|
<p>Returns a list of databases available on the server as an array. You have to
|
|||
|
|
connect to the server first. Only available for ODBC, MySQL and ADO.</p>
|
|||
|

|
|
<p><b>MetaTables<a name=metatables></a>($ttype = false, $showSchema = false,

|||
|
|
$mask=false)</b></p>
|
|||
|
|
|
|||
|
|
<p>Returns an array of tables and views for the current database as an array.
|
|||
|
|
The array should exclude system catalog tables if possible. To only show
|
|||
|
|
tables, use $db->MetaTables('TABLES'). To show only views, use
|
|||
|
|
$db->MetaTables('VIEWS'). The $showSchema parameter currently works only for
|
|||
|
|
DB2, and when set to true, will add the schema name to the table, eg.
|
|||
|
|
"SCHEMA.TABLE". </p>
|
|||
|
|
|
|||
|
|
<p>You can define a mask for matching. For example, setting $mask = 'TMP%' will
|
|||
|
|
match all tables that begin with 'TMP'. Currently only mssql, oci8, odbc_mssql
|
|||
|
|
and postgres* support $mask. </p>
|
|||
|
|
|
|||
|
|
<p><b>MetaColumns<a name=metacolumns></a>($table,$notcasesensitive=true)</b></p>
|
|||
|
|
|
|||
|
|
<p>Returns an array of ADOFieldObject's, one field object for every column of
|
|||
|
|
$table. A field object is a class instance with (name, type, max_length)
|
|||
|
|
defined. Currently Sybase does not recognise date types, and ADO cannot
|
|||
|
|
identify the correct data type (so we default to varchar). </p>
|
|||
|
|
|
|||
|
|
<p>The $notcasesensitive parameter determines whether we uppercase or lowercase
|
|||
|
|
the table name to normalize it (required for some databases). Does not work
|
|||
|
|
with MySQL ISAM tables. </p>
|
|||
|
|
|
|||
|
|
<p>For schema support, pass in the $table parameter,
|
|||
|
|
"$schema.$tablename". This is only supported for selected databases. </p>
|
|||
|
|
|
|||
|
|
<p><b>MetaColumnNames<a name=metacolumnames></a>($table,$numericIndex=false)</b></p>
|
|||
|
|
|
|||
|
|
<p>Returns an array of column names for $table. Since ADOdb 4.22, this is an
|
|||
|
|
associative array, with the keys in uppercase. Set $numericIndex=true if you
|
|||
|
|
want the old behaviour of numeric indexes (since 4.23). </p>
|
|||
|
|
|
|||
|
|
<p>e.g. array('FIELD1' => 'Field1', 'FIELD2'=>'Field2') </p>
|
|||
|
|
|
|||
|
|
<p><b>MetaPrimaryKeys<a name=metaprimarykeys></a>($table, $owner=false)</b> </p>
|
|||
|
|
|
|||
|
|
<p>Returns an array containing column names that are the primary keys of
|
|||
|
|
$table. Supported by mysql, odbc (including db2, odbc_mssql, etc), mssql,
|
|||
|
|
postgres, interbase/firebird, oci8 currently. </p>
|
|||
|
|
|
|||
|
|
<p>Views (and some tables) have primary keys, but sometimes this information is
|
|||
|
|
not available from the database. You can define a function
|
|||
|
|
ADODB_View_PrimaryKeys($databaseType, $database, $view, $owner) that should
|
|||
|
|
return an array containing the fields that make up the primary key. If that
|
|||
|
|
function exists, it will be called when MetaPrimaryKeys() cannot find a primary
|
|||
|
|
key for a table or view. </p>

<p>To get a listbox, set the $<i>size</i> to a non-zero value (or pass
|

|
|
$default_str as an array). If $<i>multiple_select</i> is true then a listbox
|
|||
|
|
will be generated with $<i>size</i> items (or if $size==0, then 5 items)
|
|||
|

visible, and we will return an array to a server. Lastly use $<i>moreAttr </i>to
|

add additional attributes such as javascript or styles. </p>

<p>Menu Example 1: <code><span style='font-size:10.0pt'>GetMenu('menu1','A',true)</span></code>

<OPTION VALUE="3">C

the data (A,1), (B,2), (C,3). Also see <a href="#ex5">example 5</a>.</p>

<p>Menu Example 2: For the same data, <code><span style='font-size:10.0pt'>GetMenu('menu1',array('A','B'),false)</span></code>
|

<p>This is nearly identical to GetMenu, except that the $<i>default_str</i> is

matched to fields[1] (the option values).</p>

|
|||
|
|
style='font-size:10.0pt'>GetMenu2('menu1',array('1','2'),false)</span></code>
|
|||
|
|
will generate a menu with both A and B selected in menu example 2, but this

<p>Moves the internal cursor to a specific row $<b>to</b>. Rows are zero-based

eg. 0 is the first row. The <b>fields</b> array is automatically updated. For

scrolling. Some databases do not support backward scrolling. If the $<b>to</b>

position is after the EOF, $<b>to</b> will move to the end of the RecordSet for

most databases. Some obscure databases using odbc might not behave this way.</p>

<p>Returns the number of rows in the record set. If the database does not
|

|
support this, it will perform a SELECT COUNT(*) on the table $table, with the
|
|||
|

given $where condition to return an estimate of the recordset size.</p>

<p>This is a standalone function (rs2html = recordset to html) that is similar

to PHP's <i>odbc_result_all</i> function, it prints a ADORecordSet, $<b>adorecordset</b>
|

|
|
as a HTML table. $<b>tableheader_attributes</b> allow you to control the table <i>cellpadding</i>,
|
|||
|
|
<i>cellspacing</i> and <i>border</i> attributes. Lastly you can replace the
|
|||
|
|
database column names with your own column titles with the array $<b>col_titles</b>.
|

recordset viewer.</p>

<h1>Database Driver Guide<a name=driverguide></a></h1>
|
|||
|
|
|
|||
|
|
<p>This describes how to create a class to connect to a new database. To ensure
|
|||
|
|
there is no duplication of work, kindly email me at jlim#natsoft.com if you
|
|||
|
|
decide to create such a class.</p>
|
|||
|
|
|
|||
|
|
<p>First decide on a name in lower case to call the database type. Let's say we
|
|||
|
|
call it xbase. </p>
|
|||
|
|
|
|||
|
|
<p>Then we need to create two classes ADODB_xbase and ADORecordSet_xbase in the
|
|||
|
|
file adodb-xbase.inc.php.</p>
|
|||
|
|
|
|||
|
|
<p>The simplest form of database driver is an adaptation of an existing ODBC
|
|||
|
|
driver. Then we just need to create the class <i>ADODB_xbase extends ADODB_odbc</i>
|
|||
|
|
to support the new <b>date</b> and <b>timestamp</b> formats, the <b>concatenation</b>
|
|||
|
|
operator used, <b>true</b> and <b>false</b>. For the<i> ADORecordSet_xbase
|
|||
|
|
extends ADORecordSet_odbc </i>we need to change the <b>MetaType</b> function.
|
|||
|
|
See<b> adodb-vfp.inc.php</b> as an example.</p>
|
|||
|
|
|
|||
|
|
<p>More complicated is a totally new database driver that connects to a new PHP
|
|||
|
|
extension. Then you will need to implement several functions. Fortunately, you
|
|||
|
|
do not have to modify most of the complex code. You only need to override a few
|
|||
|
|
stub functions. See <b>adodb-mysql.inc.php</b> for example.</p>
|
|||
|
|
|
|||
|
|
<p>The default date format of ADOdb internally is YYYY-MM-DD (Ansi-92). All
|
|||
|
|
dates should be converted to that format when passing to an ADOdb date
|
|||
|
|
function. See Oracle for an example how we use ALTER SESSION to change the
|
|||
|
|
default date format in _pconnect _connect.</p>
|
|||
|
|
|
|||
|
|
<p><b>ADOConnection Functions to Override</b></p>
|
|||
|
|
|
|||
|
|
<p>Defining a constructor for your ADOConnection derived function is optional.
|
|||
|
|
There is no need to call the base class constructor.</p>
|
|||
|
|
|
|||
|
|
<p>_<b>connect</b>: Low level implementation of Connect. Returns true or false.
|
|||
|
|
Should set the _<b>connectionID</b>.</p>
|
|||
|
|
|
|||
|
|
<p>_<b>pconnect:</b> Low level implemention of PConnect. Returns true or false.
|
|||
|
|
Should set the _<b>connectionID</b>.</p>
|
|||
|
|
|
|||
|
|
<p>_<b>query</b>: Execute a query. Returns the queryID, or false.</p>
|
|||
|
|
|
|||
|
|
<p>_<b>close: </b>Close the connection -- PHP should clean up all recordsets. </p>
|
|||
|
|
|
|||
|
|
<p><b>ErrorMsg</b>: Stores the error message in the private variable _errorMsg.

|
|
<p><b>ADOConnection Fields to Set</b></p>
|

<p><a name=5.11></a><b>5.11 5 May 2010</b> </p>
|
|||
|
|
<p>mysql: Fixed GetOne() to return null if no records returned.
|
|||
|
|
<p>oci8 perf: added stats on sga, rman, memory usage, and flash in performance tab.
|
|||
|
|
<p>odbtp: Now you can define password in $password field of Connect()/PConnect(), and it will add it to DSN.
|
|||
|
|
<p>Datadict: altering columns did not consider the scale of the column. Now it does.
|
|||
|
|
<p>mssql: Fixed problem with ADODB_CASE_ASSOC causing multiple versions of column name appearing in recordset fields.
|
|||
|
|
<p>oci8: Added missing & to refLob.
|
|||
|
|
<p>oci8: Added obj->scale to FetchField().
|
|||
|
|
<p>oci8: Now you can get column info of a table in a different schema, e.g. MetaColumns("schema.table") is supported.
|
|||
|
|
<p>odbc_mssql: Fixed missing $metaDatabasesSQL.
|
|||
|
|
<p>xmlschema: Changed declaration of create() to create($xmls) to fix compat problems. Also changed constructor adoSchema() to pass in variable instead of variable reference.
|
|||
|
|
<p>ado5: Fixed ado5 exceptions to only display errors when $this->debug=true;
|
|||
|
|
<p>Added DSN support to sessions2.inc.php.
|
|||
|
|
<p>adodb-lib.inc.php. Fixed issue with _adodb_getcount() not using $secs2cache parameter.
|
|||
|
|
<p>adodb active record. Fixed caching bug. See http://phplens.com/lens/lensforum/msgs.php?id=18288.
|
|||
|
|
<p>db2: fixed ServerInfo().
|
|||
|
|
<p>adodb_date: Added support for format 'e' for TZ as in adodb_date('e')
|
|||
|
|
<p>Active Record: If you have a field which is a string field (with numbers in) and you add preceding 0's to it the adodb library does not pick up the fact that the field has changed because of the way php's == works (dodgily). The end result is that it never gets updated into the database - fix by Matthew Forrester (MediaEquals). [matthew.forrester#mediaequals.com]
|
|||
|
|
|
|||
|
|
<p>Fixes RowLock() and MetaIndexes() inconsistencies. See http://phplens.com/lens/lensforum/msgs.php?id=18236
|
|||
|
|
<p>Active record support for postgrseql boolean. See http://phplens.com/lens/lensforum/msgs.php?id=18246
|
|||
|
|
<p>By default, Execute 2D array is disabled for security reasons. Set $conn->bulkBind = true to enable. See http://phplens.com/lens/lensforum/msgs.php?id=18270. Note this breaks backward compat.
|
|||
|
|
<P>MSSQL: fixes for 5.2 compat. http://phplens.com/lens/lensforum/msgs.php?id=18325
|
|||

|
|||
|
|

|
|
<p><a name=5.10></a><b>5.10 10 Nov 2009</b> </p>

|
|||
|
|
<p>adodb-ado.inc.php: Added BigInt support for PHP5. Will return float instead to support large numbers. Thx nasb#mail.goo.ne.jp.
|
|||
|
|
<p>adodb-mysqli.inc.php: mysqli_multi_query is now turned off by default. To turn it on, use $conn->multiQuery = true; This is because of the risks of sql injection. See http://phplens.com/lens/lensforum/msgs.php?id=18144
|
|||
|
|
<p>New db2oci driver for db2 9.7 when using PL/SQL mode. Allows oracle style :0, :1, :2 bind parameters which are remapped to ? ? ?.
|
|||
|
|
<p>adodb-db2.inc.php: fixed bugs in MetaTables. SYS owner field not checked properly. Also in $conn->Connect($dsn, null, null, $schema) and PConnect($dsn, null, null, $schema), we do a SET SCHEMA=$schema if successful connection.

|
|||
|
|
<p><a name=5.09></a><b>5.09 25 June 2009</b> </p>
|
|||
|
|
<p>Active Record: You can force column names to be quoted in INSERT and UPDATE statements, typically because you are using reserved words as column names by setting
|
|||
|
|
ADODB_Active_Record::$_quoteNames = true;
|
|||
|
|
<p>Added memcache and cachesecs to DSN. e.g.
|
|||
|
|
<pre>
|
|||
|
|
# we have a memcache servers mem1,mem2 on port 8888, compression=off and cachesecs=120
|
|||
|
|
$dsn = 'mysql://user:pwd@localhost/mydb?memcache=mem1,mem2:8888:0&cachesecs=120';

|
|||
|
|

|
|||
|

<p>Memcache supports multiple pooled hosts now. Only if none of the pooled

<p>Fixed adodb_mktime problem which causes a performance bottleneck in $hrs. </p>
|

|
|
<p>Added mysqli support to adodb_getcount(). </p>
|

<p>Active Record: $ADODB_ASSOC_CASE=1 did not work properly. Fixed. </p>
|
|||
|
|
|
|||
|
|
<p>Modified Fields() in recordset class to support display null fields in
|
|||
|
|
FetchNextObject(). </p>
|
|||
|
|
|
|||
|
|
<p>In ADOdb5, active record implementation, we now support column names with
|
|||
|
|
spaces in them - we autoconvert the spaces to _ using __set(). Thx Daniel Cook.

http://phplens.com/lens/lensforum/msgs.php?id=17200 </p>
|

|
|
|

|
|
<p>Removed $arg3 from mysqli SelectLimit. See
|
|||
|
|
http://phplens.com/lens/lensforum/msgs.php?id=16243. Thx Zsolt Szeberenyi. </p>
|
|||
|
|
|
|||
|
|
<p>Changed oci8 FetchField, which returns the max_length of BLOB/CLOB/NCLOB as
|
|||
|
|
4000 (incorrectly) to -1. </p>
|
|||
|
|
|
|||
|
|
<p>CacheExecute would sometimes return an error on Windows if it was unable to
|
|||
|
|
lock the cache file. This is harmless and has been changed to a warning that
|
|||
|
|
can be ignored. Also adodb_write_file() code revised. </p>
|
|||
|
|
|
|||
|
|
<p>ADOdb perf code changed to only log sql if execution time >= 0.05
|
|||
|
|
seconds. New $ADODB_PERF_MIN variable holds min sql timing. Any SQL with timing
|
|||
|
|
value below this and is not causing an error is not logged. </p>
|
|||
|
|
|
|||
|
|
<p>Also adodb_backtrace() now traces 1 level deeper as sometimes actual culprit
|
|||
|
|
function is not displayed. </p>
|
|||
|
|
|
|||
|
|
<p>Fixed a group by problem with adodb_getcount() for db's which are not
|
|||
|
|
postgres/oci8 based. </p>
|
|||
|
|
|
|||
|
|
<p>Changed mssql driver Parameter() from SQLCHAR to SQLVARCHAR: case 'string':
|
|||
|
|
$type = SQLVARCHAR; break. </p>
|
|||
|
|
|
|||
|
|
<p>Problem with mssql driver in php5 (for adodb 5.03) because some functions
|

|
|
|
|||
|
|
<p>ADOdb perf for oci8 now has non-table-locking code when clearing the sql.
|
|||
|
|
Slower but better transparency. Added in 4.96a and 5.02a. </p>
|
|||
|
|
|
|||
|
|
<p>Fix adodb count optimisation. Preg_match did not work properly. Also rewrote
|
|||
|
|
the ORDER BY stripping code in _adodb_getcount(), adodb-lib.inc.php. </p>
|
|||
|
|
|
|||
|
|
<p>SelectLimit for oci8 not optimal for large recordsets when offset=0. Changed
|
|||
|
|
$nrows check. </p>
|
|||
|
|
|
|||
|
|
<p>Active record optimizations. Added support for assoc arrays in Set(). </p>
|
|||
|
|
|
|||
|
|
<p>Now GetOne returns null if EOF (no records found), and false if error
|
|||
|
|
occurs. Use ErrorMsg()/ErrorNo() to get the error. </p>
|
|||
|
|
|
|||
|
|
<p>Also CacheGetRow and CacheGetCol will return false if error occurs, or empty
|
|||
|
|
array() if EOF, just like GetRow and GetCol. </p>
|
|||
|
|
|
|||
|
|
<p>Datadict now allows changing of types which are not resizable, eg. VARCHAR
|
|||
|
|
to TEXT in ChangeTableSQL. -- Mateo Tibaquir<69> </p>
|
|||
|
|
|
|||
|
|
<p>Added BIT data type support to adodb-ado.inc.php and adodb-ado5.inc.php. </p>
|
|||
|
|
|
|||
|
|
<p>Ldap driver did not return actual ldap error messages. Fixed. </p>
|
|||
|
|
|
|||
|
|
<p>Implemented GetRandRow($sql, $inputarr). Optimized for Oci8. </p>
|
|||
|
|
|
|||
|
|
<p>Changed adodb5 active record to use static SetDatabaseAdapter() and removed
|
|||
|
|
php4 constructor. Bas van Beek bas.vanbeek#gmail.com. </p>
|
|||
|
|
|
|||
|
|
<p>Also in adodb5, changed adodb-session2 to use static function declarations
|
|||
|
|
in class. Thx Daniel <st1:State w:st="on"><st1:place w:st="on">Berlin</st1:place></st1:State>.
|
|||
|
|
</p>
|
|||
|
|
|
|||
|
|
<p>Added "Clear SQL Log" to bottom of Performance screen. </p>
|
|||
|
|
|
|||
|
|
<p>Sessions2 code echo'ed directly to the screen in debug mode. Now uses
|
|||
|
|
ADOConnection::outp(). </p>
|
|||
|
|
|
|||
|
|
<p>In mysql/mysqli, qstr(null) will return the string "null" instead
|
|||
|
|
of empty quoted string "''". </p>

Stefano Nari. </p>
|
|||
|
|
|
|||
|
|
<p>Code sanitization introduced in 4.95 caused problems in European locales (as
|
|||
|
|
float 3.2 was typecast to 3,2). Now we only sanitize if is_numeric fails. </p>
|
|||
|
|
|
|||
|
|
<p>Added support for customizing ADORecordset_empty using
|
|||
|
|
$this->rsPrefix.'empty'. By Josh Truwin. </p>

|
persistent, even non-persistent ones. Fixed.</p>
|

- MySql and Postgres MetaType was reporting every int column which was part of

|||
|
|
a primary key and unique as serial<br>
|
|||
|
|
- Postgres was not reporting the scale of decimal types<br>
|
|||
|
|
- MaxDB was padding the defaults of none-string types with spaces<br>
|
|||
|
|
- MySql now correctly converts enum columns to varchar </p>
|
|||
|
|
|
|||
|
|
<p>Ralf also changed Postgresql datadict:<br>
|
|||
|
|
- you cant add NOT NULL columns in postgres in one go, they need to be added as
|
|||
|
|
NULL and then altered to NOT NULL<br>
|
|||
|
|
- AlterColumnSQL could not change a varchar column with numbers into an integer
|
|||
|
|
column, postgres need an explicit conversation<br>
|
|||
|
|
- a re-created sequence was not set to the correct value, if the name was the
|
|||
|
|
old name (no implicit sequence), now always the new name of the implicit
|
|||
|
|
sequence is used</p>

<p>FetchMode cached in recordset is sometimes mapped to native db fetchMode.
|

|
|
Normally this does not matter, but when using cached recordsets, we need to

switch back to using adodb fetchmode. So we cache this in

$rs->adodbFetchMode if it differs from the db's fetchMode. </p>

<p>New sqlitepo driver. This is because assoc mode does not work like other
|
|||
|
|
drivers in sqlite. Namely, when selecting (joining) multiple tables, in assoc
|
|||
|
|
mode the table names are included in the assoc keys in the "sqlite"
|
|||
|
|
driver. In "sqlitepo" driver, the table names are stripped from the
|
|||
|
|
returned column names. When this results in a conflict, the first field get
|
|||
|
|
preference. Contributed by Herman Kuiper herman#ozuzo.net </p>

<p>New interbase/firebird fixes thx to Lester Caine. Driver fixes a problem
|
|||
|
|
with getting field names in the result array, and corrects a couple of data
|
|||
|
|
conversions. Also we default to dialect3 for firebird. Also ibase sysDate
|
|||
|
|
property was wrong. Changed to cast as timestamp. </p>

|
<p>The datadict driver is set up to give quoted tables and fields as this was
|
|||
|
|
the only way round reserved words being used as field names in TikiWiki.
|
|||
|
|
TikiPro is tidying that up, and I hope to be able to produce a build of THAT
|
|||
|
|
which uses what I consider proper UPPERCASE field and table names. The
|
|||
|
|
conversion of TikiWiki to ADOdb helped in that, but until the database is
|
|||
|
|
completely tidied up in TikiPro ... </p>

<p>Modified _gencachename() to include fetchmode in name hash. This means you

name algorithm has changed. </p>
|

|
|
|

|
|
<p>Now Cache* functions work in safe mode, because we do not create
|
|||
|
|
sub-directories in the $ADODB_CACHE_DIR in safe mode. In non-safe mode we still
|
|||
|
|
create sub-directories. Done by modifying _gencachename(). </p>
