Collection type support in Forms version 6.0.8.11.3

Question

Hi
I am trying to call this from forms.
I am getting error no data found whenever this calls IF condition but from backend if run it from a script it works fine.
So I was thinking whether Forms PL/SQL version supports collection types.
I am using Forms [32 Bit] Version 6.0.8.11.3 (Production).
IF (p_emp_ids.COUNT > 0) THEN
FOR r IN v_emp_ids.FIRST..v_pkg_ids.LAST LOOP
Thanks in Advance

Answer 1

Is it just a a typo that the IF is on P_emp_ids and the loop is on V_em_ids?
However: the NO_DATA_FOUND exception suggests that you may be falling down a crack in your collection. If you have a missing element between FIRST and LAST you will get a no_data_found. Suppose these elements are there:
(1), (2). (3), (5), (6)
You will start at FIRST (1) and finish at LAST (6). But your loop on R will try to find the element at (4). Which isn't there. Oops...
To prove that's what's happening, you can wrap the inside of the loop with an exception handler
   BEGIN
      do the access to v_emp_ids(r)
   EXCEPTION
      WHEN NO_DATA_FOUND then (log a message with the value if R in it)
   END;If you want to walk a collection with gaps (a "sparse" collection), this is the way:
  DECLARE
     r pls_integer;
  BEGIN
     r := v_empids.FIRST
     LOOP
         EXIT when r IS NULL;
         do the business on v_empids(r);
         r := v_empids(r).NEXT;
     END LOOP;Now, why didn't this work in Forms, but did on the server? Possible reasons:
- your back end script was set up differently - so you had a dense collection (no gaps)
- Client side PL/SQL is different from server side (is it still version 1.x?)
