db2_autocommit

Returns or sets the AUTOCOMMIT state for a database connection

&reftitle.description; `mixed` `db2_autocommit` `resource` `connection` `bool` `value`

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

&reftitle.parameters;

`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.

&reftitle.returnvalues;

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. &return.success;

&reftitle.examples;

### 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.";
    }
    ?>

&example.outputs;

    0 -- AUTOCOMMIT is off.

### 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.";
    }
    ?>

&example.outputs;

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