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
例子 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.";
}
?>

例子 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.";
}
?>

上例将输出： Turning AUTOCOMMIT on succeeded.
1 -- AUTOCOMMIT is on. |
