oci_commitCommits the outstanding database transaction

Beschreibung

bool oci_commit ( resource $connection )

Commits the outstanding transaction for the Oracle connection. A commit ends the current transaction and makes permanent all changes. It releases all locks held.

A transaction begins when the first SQL statement that changes data is executed with oci_execute() using the OCI_NO_AUTO_COMMIT flag. Further data changes made by other statements become part of the same transaction. Data changes made in a transaction are temporary until the transaction is committed or rolled back. Other users of the database will not see the changes until they are committed.

When inserting or updating data, using transactions is recommended for relational data consistency and for performance reasons.

Parameter-Liste

connection

An Oracle connection identifier, returned by oci_connect(), oci_pconnect(), or oci_new_connect().

Rückgabewerte

Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben.

Beispiele

Beispiel #1 oci_commit() example

<?php

// Insert into several tables, rolling back the changes if an error occurs

$conn oci_connect('hr''welcome''localhost/XE');

$stid oci_parse($conn"INSERT INTO mysalary (id, name) VALUES (1, 'Chris')");

// The OCI_NO_AUTO_COMMIT flag tells Oracle not to commit the INSERT immediately
// Use OCI_DEFAULT as the flag for PHP <= 5.3.1.  The two flags are equivalent
$r oci_execute($stidOCI_NO_AUTO_COMMIT);
if (!
$r) {    
    
$e oci_error($stid);
    
trigger_error(htmlentities($e['message']), E_USER_ERROR);
}

$stid oci_parse($conn'INSERT INTO myschedule (startday) VALUES (12)');
$r oci_execute($stidOCI_NO_AUTO_COMMIT);
if (!
$r) {    
    
$e oci_error($stid);
    
oci_rollback($conn);  // rollback changes to both tables
    
trigger_error(htmlentities($e['message']), E_USER_ERROR);
}

// Commit the changes to both tables
$r oci_commit($conn);
if (!
r) {
    
$e oci_error($conn);
    
trigger_error(htmlentities($e['message']), E_USER_ERROR);
}

?>

Anmerkungen

Hinweis:

Transactions are automatically rolled back when you close the connection, or when the script ends, whichever is soonest. You need to explicitly call oci_commit() to commit the transaction.

Any call to oci_execute() that uses OCI_COMMIT_ON_SUCCESS mode explicitly or by default will commit any previous uncommitted transaction.

Any Oracle DDL statement such as CREATE or DROP will automatically commit any uncommitted transaction.

Hinweis:

In PHP versions before 5.0.0 you must use ocicommit() instead. Der alte Funktionsname kann noch immer verwendet werden, dies ist jedoch veraltet und wird nicht empfohlen.
