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. 锟节碉拷前锟芥本锟叫ｏ拷锟缴的猴拷锟斤拷锟斤拷锟斤拷锟斤拷锟皆憋拷使锟矫ｏ拷锟斤拷锟窖撅拷锟斤拷锟斤拷锟斤拷锟斤拷锟斤拷锟斤拷锟斤拷使锟矫★拷
