Example #1 oci_rollback() 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);
}
?>
Example #2 Rolling back to a SAVEPOINT example
<?php
$stid = oci_parse($conn, 'UPDATE mytab SET id = 1111');
oci_execute($stid, OCI_NO_AUTO_COMMIT);
// Create the savepoint
$stid = oci_parse($conn, 'SAVEPOINT mysavepoint');
oci_execute($stid, OCI_NO_AUTO_COMMIT);
$stid = oci_parse($conn, 'UPDATE mytab SET id = 2222');
oci_execute($stid, OCI_NO_AUTO_COMMIT);
// Use an explicit SQL statement to rollback to the savepoint
$stid = oci_parse($conn, 'ROLLBACK TO SAVEPOINT mysavepoint');
oci_execute($stid, OCI_NO_AUTO_COMMIT);
oci_commit($conn); // mytab now has id of 1111
?>
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() 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.
Note:
In PHP versions before 5.0.0 you must use ocirollback() instead. �ڵ�ǰ�汾�У��ɵĺ����������Ա�ʹ�ã����Ѿ���������������ʹ�á�
