Возвращаемые значения
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.
Возвращает TRUE
в случае успешного завершения или FALSE
в случае возникновения ошибки.
Примеры
Пример #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 ($ac == 0) {
print "$ac -- AUTOCOMMIT is off.";
} else {
print "$ac -- AUTOCOMMIT is on.";
}
?>
Результат выполнения данного примера:
0 -- AUTOCOMMIT is off.
Пример #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 ($ac == 0) {
print "$ac -- AUTOCOMMIT is off.";
} else {
print "$ac -- AUTOCOMMIT is on.";
}
?>
Результат выполнения данного примера:
Turning AUTOCOMMIT on succeeded. 1 -- AUTOCOMMIT is on.
