# oci_commit

(PHP 5, PECL OCI8 >= 1.1.0)

oci_commit — Commits the outstanding database transaction

### Opis

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.

### Parametry

`connection`

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

### Zwracane wartości

Zwraca `TRUE` w przypadku powodzenia, `FALSE` w przypadku błędu.

### Przykłady

Przykład #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
$r = oci_execute($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);
}
?>`

### Notatki

> Informacja: 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.

> Informacja: In PHP versions before 5.0.0 you must use ocicommit() instead. The old function name can still be used in current versions, however it is deprecated and not recommended.
