OCI_COMMIT(3)															     OCI_COMMIT(3)

oci_commit - Commits the outstanding database transaction

SYNOPSIS
       bool oci_commit (resource  $connection)

DESCRIPTION
	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(3)  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.

PARAMETERS
	      o $connection
		- An Oracle connection identifier, returned by oci_connect(3), oci_pconnect(3), or oci_new_connect(3).

RETURN VALUES
	Returns TRUE on success or FALSE on failure.

EXAMPLES
       Example #1

	      oci_commit(3) 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);
	      }

	      ?>

NOTES
       Note

	       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(3) to commit the transaction.

	       Any  call  to  oci_execute(3)  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.
