Answer 1

As far as I can see, the 2 cursors are identical:
cursor c1 is
select 'x' from dlo
where order_no=p_no
and
qty_ord>nvl(qty_rec,0);
c2 is
3          select 'x' from dlo
where order_no=p_no
d
15               qty_ord=nvl(qty_rec,0);Which would make:
if c1%found then
     open c2;
     fetch c2 into l_res;
     if c2%found then
          return 0 ;
     ELSE
return 1 ; --THIS line unreachable since if
since if c1 is found then c2 HAS to be found (they're
both the same)
     end if;
I have to ask the OP, what are you REALLY trying to
do. Is this just an academic exercise? What is the
purpose (note I'm not asking what the end result will
be, I'm asking what the purpose is)Hi JS1,
I wonder have you read the complete post or just jumped into conclusion after reading
the first post.
As far as I can see, the 2 cursors are identical: No they are not identical.
8 cursor c1 is
9 select 'x' from dlo where order_no=p_no
10 and
11 qty_ord>nvl(qty_rec,0);
12 cursor c2 is
13 select 'x' from ordloc where order_no=p_no
14 and
15 qty_ord=nvl(qty_rec,0);.............
