db2_autocommit
Returns or sets the AUTOCOMMIT state for a database connection
Description
intbool db2_autocommit(resource $connection, int $value = ?)
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
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.
Returns true on success or false on failure.
Examples
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.";
}
?>
The above example will output:
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.";
}
?>
The above example will output:
Turning AUTOCOMMIT on succeeded.
1 -- AUTOCOMMIT is on.
