Handling cascading LOV (having Multi-Select parent LOV)

Question

Hi,
I am using cascading LOV.
P1_PARENT - Parent LOV (which is multi-select)
P1_CHILD - Child LOV
since Parent LOV is multi-select, so it will have the following vallues... P1_PARENT = AA:BB:CC
and the where clause in the cascading LOV should be like
       where col1 in (:P1_PARENT)
   - So how to convert item value for P1_PARENT from AA:BB:CC to 'AA','BB','CC'
- Is there is any other way to handle cascading LOV (for Multi-Select parent LOV).
select list for P1_CHILD
    select d, r
  from test
where col1 = :P1_PARENT
where col1 in (:P1_PARENT) Thanks,
Deepak

Hi Deepak,
In the where clause for the child LOV, you can use instr function as:
(instr(':'||:P1_PARENT||':',':'||col1||':',1) > 0 ) To access the individual elements in the multi-select :P1_PARENT, you can use:
DECLARE
l_selected HTMLDB_APPLICATION_GLOBAL.VC_ARR2;
BEGIN
  l_selected := HTMLDB_UTIL.STRING_TO_TABLE(:P1_PARENT);
  FOR i IN 1..l_selected.count
  LOOP
        //  your code here...access individual elements using  l_selected(i)
  END LOOP;
END;Thanks,
