A trigger is a special kind of stored procedures that automatically executes when an event occurs in the database server. Insert, update and delete are called as events.
Trigger is a statement that is automatically executed by the system as a side effect of a modification to the database. Several existing systems have their own non standard trigger functions. For a trigger we need to specify the condition under which the trigger is executed.
