What are the types of triggers ?
Answer Posted / mohit tyagi(siyana bulandshaha
Basically there are three types of triggers, but the way to
use is differ. it doesn't matter on which we are
implementing these trigger.
triggers are:-
1. Cyclic Cascading Triggers.
2. Mutating Triggers.
3. Insted Off Triggers.
we can implement all these trigger on both module i.e
1.Application
2.Database
these both module are associate with the type of
implementation i.e.
1. Insert/delete/update
2. Before/After
3. Statement level/Row level
except this theory there are various ways to represent the
sql trigger. but all have the same concept for
implementation. so never confuse in order to represent the
sql trigger.
