oci_commit — Commits the outstanding database transaction
$connection
) : bool
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.
connectionAn Oracle connection identifier, returned by oci_connect(), oci_pconnect(), or oci_new_connect().
Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben.
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
$r = oci_execute($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);
}
?>
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_SUCCESSmode 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.
