Answer Posted / malini paul
1.Constraint is a statement about a database that is always
true.Whereas triggers constrain what a transaction can do.
2.Constrain applies to existing data in the table and any
statement that manipulates the table.Whereas Trigger does
not apply to data loaded before the trigger was created.
