Answer Posted / jerry joseph
Restricting the input using CONSTRAINT will have better
performance but there is a limit to the types of constraints
which we can provide..
With TRIGGERS you have more flexibility and provide a more
variety restrictions to the input.. for example you can
prevent a normal delete and make it a soft delete by setting
an IsDeleted flag using trigger.. we cant have that kind of
flexibility using Constraints..
