db2_autocommit -- Returns or sets the AUTOCOMMIT state for a database connection

Descripción

mixed db2_autocommit ( resource connection [, bool value] )

Sets or gets the AUTOCOMMIT behavior of the specified connection resource.

Lista de parámetros

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.

Valores retornados

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. Devuelve TRUE si todo se llevó a cabo correctamente, FALSE en caso de fallo.

Ejemplos

Ejemplo 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.";
}
?>

El resultado del ejemplo seria:

0 -- AUTOCOMMIT is off.

Ejemplo 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.";
}
?>

El resultado del ejemplo seria:

Turning AUTOCOMMIT on succeeded.
1 -- AUTOCOMMIT is on.
