db2_autocommit
(PECL)
db2_autocommit --
Returns or sets the AUTOCOMMIT state for a database connection
说明
mixed
db2_autocommit ( resource connection [, bool value] )
Sets or gets the AUTOCOMMIT behavior of the specified connection resource.
参数
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.
返回值
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.
如果成功则返回 TRUE，失败则返回 FALSE。
范例
例 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.";
}
?>

例 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.";
}
?>
