Cancels any changes made since a SAVEPOINT.
ROLLBACK TO SAVEPOINT [ savepoint-name ]
The ROLLBACK TO SAVEPOINT statement will undo any changes that have been made since the SAVEPOINT was established.
Changes made prior to the SAVEPOINT are not undone; they are still pending.
The savepoint-name is an identifier that was specified on a SAVEPOINT statement within the current transaction. If savepoint-name is omitted, the most recent savepoint is used. Any savepoints since the named savepoint are automatically released.
