PHP : Function Reference : IBM DB2, Cloudscape and Apache Derby Functions : db2_autocommit

db2_autocommit

Returns or sets the AUTOCOMMIT state for a database connection (PECL ibm_db2:1.0-1.6.2)
mixed db2_autocommit ( resource connection [, bool value] )

Sets or gets the AUTOCOMMIT behavior of the specified connection resource.

Parameters

connection

A valid database connection resource variable as returned from db2_connect() or db2_pconnect().

value

One of the following constants:

DB2_AUTOCOMMIT_OFF

Turns AUTOCOMMIT off.

DB2_AUTOCOMMIT_ON

Turns AUTOCOMMIT on.

Return Values

When db2_autocommit() receives only the connection parameter, it returns the current state of AUTOCOMMIT for the requested connection as an integer value. A value of 0 indicates that AUTOCOMMIT is off, while a value of 1 indicates that AUTOCOMMIT is on.

When db2_autocommit() receives both the connection parameter and autocommit parameter, it attempts to set the AUTOCOMMIT state of the requested connection to the corresponding state. Returns TRUE on success or FALSE on failure.

Examples

Example 911. Retrieving the AUTOCOMMIT value for a connection

In the following example, a connection which has been created with AUTOCOMMIT turned off is tested with the db2_autocommit() function.

<?php
$options
= array('autocommit' => DB2_AUTOCOMMIT_OFF);
$conn = db2_connect($database, $user, $password, $options);
$ac = db2_autocommit($conn);
if (
$ac == 0) {
   print
"$ac -- AUTOCOMMIT is off.";
} else {
   print
"$ac -- AUTOCOMMIT is on.";
}
?>

The above example will output:

0 -- AUTOCOMMIT is off.


Example 912. Setting the AUTOCOMMIT value for a connection

In the following example, a connection which was initially created with AUTOCOMMIT turned off has its behavior changed to turn AUTOCOMMIT on.

<?php
$options
= array('autocommit' => DB2_AUTOCOMMIT_OFF);
$conn = db2_connect($database, $user, $password, $options);

// Turn AUTOCOMMIT on
$rc = db2_autocommit($conn, DB2_AUTOCOMMIT_ON);
if (
$rc) {
   print
"Turning AUTOCOMMIT on succeeded.\n";
}

// Check AUTOCOMMIT state
$ac = db2_autocommit($conn);
if (
$ac == 0) {
   print
"$ac -- AUTOCOMMIT is off.";
} else {
   print
"$ac -- AUTOCOMMIT is on.";
}
?>

The above example will output:

Turning AUTOCOMMIT on succeeded.
1 -- AUTOCOMMIT is on.
