What is the relation b/w view and trigger..

Answer / rajesh venati

View are classified in to two types.
1. Simple View
2. Complex View

==>DML Operations are not possible in complex views, because,
if u create a view more than one table or
if u create a view using group function or
if u create a view using distinct keyword etc.,
those are called complex view.

If u want perform DML Operations on Complex Views, then we
will go for Instead of Trigger.

Through the Instead of Triggers we can perform DML
Operations on a Complex View.
