(PECL ibm_db2 >= 1.0.0)
db2_autocommit — Returns or sets the AUTOCOMMIT state for a database connection
Sets or gets the AUTOCOMMIT behavior of the specified connection resource.
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.
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
DB2_AUTOCOMMIT_OFF
indicates that AUTOCOMMIT is off, while a value of DB2_AUTOCOMMIT_ON
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.

Example #1 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 ($ac == DB2_AUTOCOMMIT_OFF) {
print "$ac -- AUTOCOMMIT is off.";
} else {
print "$ac -- AUTOCOMMIT is on.";
}
?>
Exemplul de mai sus va afișa:
0 -- AUTOCOMMIT is off.
Example #2 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 ($ac == DB2_AUTOCOMMIT_OFF) {
print "$ac -- AUTOCOMMIT is off.";
} else {
print "$ac -- AUTOCOMMIT is on.";
}
?>
Exemplul de mai sus va afișa:
Turning AUTOCOMMIT on succeeded. 1 -- AUTOCOMMIT is on.
