A trigger is a special kind of stored procedure that goes
into effect when you modify data in a specified table using
one or more data modification operations: UPDATE, INSERT,
or DELETE. Triggers can query other tables and can include
complex SQL statements. They are primarily useful for
enforcing complex business rules or requirements. For
example, you could control whether to allow an order to be
inserted based on a customer's current account status.
