Hi:

I have the following PL/PgSQL code blocks:

a) IF (condition) THEN
      RAISE EXCEPTION ''Cannot Insert'';
   END IF;

b) IF (condition) THEN
      RAISE NOTICE ''Cannot Insert'';
      RETURN NULL;
   END IF;


   What is the difference between the first and second
chunk PL/PgSQL INSERT/UPDATE trigger function code
aside from the fact that first scenario will result in
an "ABORT" state?

  Are there any instances where a NOTICE and a RETURN
NULL statement is a much better than a RAISE EXCEPTION
statement?


Thank you very much,

ludwig lim

Not that I have encountered, but YMMV.
