What else can be used

Question

Hi all,
am having problem to iterate to next record when using when validate record trigger.
what else can be used instead of next_record to iterate through?
thanks.

Answer 1

following is the problem where i have to calculate backlog by comparing it with the value presented in the database and that of the changed by user.
for exmaple in ven_share table share_quota defined was 100% and user changes it to 40 backlog should contain 60
upto this my logic is working fine but when i iterate to next record i want backlog to show previous + newly changed value..
can you suggest now how can it work in any other way??
declare
     v_share number(3);
     bck number(4);
--     total_bck number(3);
cursor c1 is select share_quota from ven_share where vendor_code=:ven_share.vendor_code;
begin
          first_record;
--open c1;
--fetch c1 into v_share;
for i in c1
loop
     v_share:=i.share_quota;
     if v_share<>:ven_share.share_quota--,:system.cursor_record
          then
          if v_share>:ven_share.share_quota
               then
               :ven_share.backlog:=v_share-:ven_share.share_quota;
               bck:=:ven_share.backlog;
               --next_record;
--     total_bck:=bck+v_share-:ven_share.share_quota;
          end if;
     end if;
--          if :ven_share.vendor_code is null
--               then
--                    null;
                    --bck:=:ven_share.backlog;
          --     else
          --     if v_share>:ven_share.share_quota then
                                   --     message(v_share);
     --     message(:ven_share.share_quota);
          --          :ven_share.backlog:=bck+v_share-:ven_share.share_quota;
     --     end if;     
--          end if;
     --     end if;
--     end if;
EXIT WHEN :SYSTEM.LAST_RECORD ='TRUE';
--NEXT_RECORD;     
end loop;
end;
thanks
