executed when ever a DML operation is made on a perticular
table.
Trigger is identical with procedure but the basic

what is trigger?..

Answer / dhanalakshmi parthasarathy

Triggers are simply stored procedures that are ran
automatically by the database whenever
some event (usually a table update) happens. We won’t spend
a great deal of time talking
about how to write triggers, because if you know how to
write stored procedures, you already
know how to write triggers. What we will discuss is how to
set them up to be executed whenever something happens to
the table.
