Can i use array.count in line?

Question

All,
I have one small oracle program that take a ',' separated string as an input
and assigns the individual string to a nested table.
I am wondering if I can directly use array.count in my sql below
instead of assigning the count of the array 1st and then
using it.
l_cause_codes_array := util_pkg.tokenize_string(p_cause_codes_csv, ',');
l_count := l_cause_codes_array.count;
My current sql:
delete from po_complaint_cause p
where p.po_number = p_po_number
and p.comp_code = p_comp_code
and l_count > 1;
I would like to do something like:
delete from po_complaint_cause p
where p.po_number = p_po_number
and p.comp_code = p_comp_code
and l_l_cause_codes_array.count> 1;
I just want to reduce one context switch if possible.
Thanks.

Hi,
did it give an error? Did you try? But it is possible.
But why not the next code:
  l_cause_codes_array := util_pkg.tokenize_string(p_cause_codes_csv, ',');
  if l_cause_codes_array.count >1
  then
    delete from po_complaint_cause p
    where p.po_number = p_po_number
    and p.comp_code = p_comp_code
  end if;Do only the delete if it is bigger than 1, that is I think the fastest switch.
