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
and which command i could used to fill column fm_balance with 1000?
please gimme some idea...???
thank's
