A transaction begins when the first SQL statement that changes data is executed with using the 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. oci_execute``OCI_NO_AUTO_COMMIT

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

Voorbeeld: 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
$r = oci_execute($stid, OCI_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)');
$r = oci_execute($stid, OCI_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);
}
