Answer Posted / ganesh
Trigger: A set of pl/sql statments that are stored
permenantly in the database it activates when ever the DML
operations performed on the table.
constraints: Set of predefind rules are applied on table
column while creating the table or after creating the
table. and automatically performed when DML statemets are
performed by user.
the main differece between the two is
trigger will not effect the existing rows(it will effects
only new rows after creating a trigger on a table),
where as in the constraints it will effect the existing
rows also.
