Rückgabewerte
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.
Gibt bei Erfolg true zurück. Bei einem Fehler wird false zurückgegeben.
Beispiele
Beispiel #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.";
}
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
0 -- AUTOCOMMIT is off.
Beispiel #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.";
}
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
Turning AUTOCOMMIT on succeeded. 1 -- AUTOCOMMIT is on.
