반환값

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. 성공 시 TRUE를, 실패 시 FALSE를 반환합니다.

예제

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 (
$ac == 0) {
    print 
"$ac -- AUTOCOMMIT is off.";
} else {
    print 
"$ac -- AUTOCOMMIT is on.";
}
?>

위 예제의 출력:

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
$rc db2_autocommit($connDB2_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.";
