When an ERROR function is invoked, the execution of the current process terminates, the message is immediately displayed, and the database returns to the status it had following the last (implicit or explicit) COMMIT function as though the process calling the ERROR function had not run at all.

We can use the ERROR function in combination with the MESSAGE function to assist in repetitive testing.

Because the ERROR function rolls back all database changes, this technique allows us to run through multiple tests against the same data without any time-consuming backup and restoration ...
