Hi all
I am having some Foreign key constraints in some of my tables
and i have created the screens for those tables in the front end.
Now i want to disable/drop these foriegn key constraints,but i am getting afraid to do so because it may affect my front end screens, i want to know that
Whether my screens will work normaly and works as a master detail or not, if i will drop/disable the constraints from back end?
if it does, what i have to do to overcome it
any one , please help me it is urgent

Why in first place do you want to drop Backend Constraints?
If you do so and if somebody enters some Junk data into your Detail table then he will not be stopped although no Coresponding Master exists in the Database.
This will have major problems of Data integrity in your System.

Hi,
I am dropping the constraints because i am writing some database triggers, to insert update and delete detail table if master is being updated or modified.
Even if i am writing these triggers Do i need to keep the constraints or i have to drop it?
Waiting for your replay
