Re: Anyone using Triggers to enforce data validation & business rules?

I would ask this: When you write a new approach, like writing the first non-5250 solution, can you include the appropriate non-5250 error handling into the trigger program, too?

Would it be possible, for interactive jobs, to do a *BEFORE trigger and

It makes sense to me to put data validation and referential integrity
constraints in *BEFORE triggers - where an exception automatically stops
the DBMS from changing the record.

I suppose an error window in the Trigger program would work for 5250 users.
But what about web applications, etc?
