[SQL] update column with rowtype

[betty]

Hi..

I try "rowtype" in trigger, ex:
create or replace function fn_tr_aiu_pdcblc() returns trigger as '
declare
   c_pdcblc cursor for select * from t_pdcblc where fc_branch=new.fc_branch
and fc_bankacct=new.fc_bankacct;
   balance decimal(30,5);
   row_pdcblc t_pdcblc%rowtype;
begin
    balance:=0;
    if (select count(*) from t_pdcblc where fc_branch=new.fc_branch and
fc_bankacct=new.fc_bankacct and fd_trxdate<new.fd_trxdate)>0 then
        balance:=new.fm_balance from t_pdcblc where fc_branch=new.fc_branch
and fc_bankacct=new.fc_bankacct and fd_trxdate<new.fd_trxdate;
    end if;
    open c_pdcblc;
    for c_pdc in 1..(select count(*) from t_pdcblc where
fc_branch=new.fc_branch and fc_bankacct=new.fc_bankacct and
fd_trxdate>=new.fd_trxdate) loop
        fetch c_pdcblc into row_pdcblc;
        row_pdcblc.fm_balance :=
balance+row_pdcblc.fm_masuk-row_pdcblc.fm_keluar;
        raise  notice ''balance %'',row_pdcblc.fm_balance;
        new.fm_balance := row_pdcblc.fm_balance;
    end loop;
    close c_pdcblc;
    return new;
end;' language 'plpgsql';

the result of this trigger is;
  oid      |     fd_trxdate                |  fm_masuk    | fm_keluar |
fm_balance
--------+---------------------    +------------ +-----------+------------
 562784 | 2003-02-06 00:00:00 | 1000.00000 |   0.00000 |    0.00000
