Answer 1

Hi APC thank u very much. One more doubt.
in 1st cursor I mentioned query as
select q_ord,q_rcv from dloc where order_no=p_no and q_ord=nvl(q_rcv,0).
in 2nd sursor i mentioned it as
select q_ord,q_rcv from dloc where order_no=p_no and q_ord>nvl(q_rcv,0)
in function :
open c2
if c2%found then
open c1
if c1%found then
return 0;
i wrote like this. but I am not able to find the following requirement. I have already given this. pls check it and give me clue...pls
select distinct 'x'
from ordloc
where order_no = P_ORD
and qty_ordered > nvl(qty_received, 0)
Please use this query to find the order is `OPEN` or `CLOSED`.
Declare one more cursor for this query, open the cursor with the `IF` condition. If the cursor returns ‘x’ then `Block the Message` otherwise `Allow the Message`.
here I wrote code for single cursor. i./e
Create or replace Function AAAA(orderno number) return number is
Cursor c1 is select distinct 'x'
from ordloc
where order_no = P_ORD
and qty_ordered > nvl(qty_received, 0) ;
dummy varchar2(1);
begin
Open c1;
fetch c1 into dummy;
close c1;;
if dummy='X' then
return 1;
else
return 0;
end if;
Exception
when no_data_found then
Message('No such Order');
when others
Message (sqlcode);
end;
but i'm not able to use 2nd cursor in this .plz let me know.
thank u
