What is Trigger?

Answer Posted / kaushik chatterjee

A trigger is some what simillar to stored procedure. It is
written to perform a set of predefined actions when a
perticular database objecy such as tables,views are
DELETED,INSERTED,UPDATED.
Triggers are implicitly called and are NOT instactiated by
the user. Once written, it will be called automatically by
the DBMS engine when a UPDATE/DELETE/INSERT operation is
performed on the database object for which the trigger is
intended or written.
Triggers can be written for any one of the 3 operations
written above or all of them.
