Question

select a. b_name, b.VESSEL ,b.vessel_date, sum(nvl(b.qty,0)) Econt_QTY,
     x.b_name,y.vessel,y.vessel_date, sum(nvl(y.iqty,0)) Issue_qty
                         from mol_exp a, sub_mol_exp b,
                         mol_issue x , sub_mol_issue y
where a.mexp_no = b.mexp_no
     and x.alcexp_no = y.alcexp_no
     and b.vessel = y.vessel
group by a. b_name, b.VESSEL ,b.vessel_date,
          x.b_name,y.vessel,y.vessel_date
--b.qty = 1000
-- y.iqty = 500 but it is showin 1000 any one guid me why it is happning.

Answer 1

your 2nd query is working but it is also adding quantity 2 times.
actual quantity I have 202 but returning 404.

Thank you so much all of you.
I used this cursor in when button press trigger now it is working fine
