Вратени вредности
Кога 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.
Кога db2_autocommit() receives both the
connection параметарот и
autocommit parameter, it attempts to set the AUTOCOMMIT state of the requested connection to the corresponding state. Returns true на успех или false при неуспех.
Примери
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.";
}
?>Пример #1 Пример што покажува затворачка ознака што го опфаќа последниот нов ред
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.";
}
?>Пример #1 Пример што покажува затворачка ознака што го опфаќа последниот нов ред
