Answer 1

Thanks a lot..
User may select 20-30 check boxes for respective name & id...then at the end , user will hit OK...from here when-button-click will call a procedure....that will update/insert/delete a table data.The procedure I have written is:-
DECLARE
N_CNT Number(1);
D_SYSDATE Constant date :=sysdate;
Begin
select count(1)
into N_CNT
from dbtable L
where L.land_id = :BLK1.LAND_ID and
L.Operatoer_id = :BLK1.Operatoer_id and
L.suppl_id = :BLK1.suppl_id and
L.suppl_prof_id = :BLK1.suppl_prof_id;
if ((N_CNT = 0) and (:LANDLISTE.state = 'A')) then
insert into dbtable
LAND_ID,
STATE,
suppl_prof_id,
suppl_id,
OPERATOER_ID,
SIDST_OPD_DATO,
SIDST_OPD_INIT
values
:BLK1.LAND_ID,
'Y',
:BLK1.suppl_prof_id,
:BLK1.suppl_id,
:BLK1.Operatoer_id,
D_SYSDATE,
:BLK1.SIDST_OPD_INIT
elseif
((N_CNT>0 )and (:LANDLISTE.state = 'A')) then
update dbtable L
set L.SIDST_OPD_DATO = D_SYSDATE,
L.SIDST_OPD_INIT = :BLK1.SIDST_OPD_INIT
where L.land_id = :BLK1.LAND_ID and
L.Operatoer_id = :BLK1.Operatoer_id and
L.suppl_id = :BLK1.suppl_id and
L.suppl_prof_id = :BLK1.suppl_prof_id;
elseif ((N_CNT>0 ) and (:LANDLISTE.state = 'D')) then
delete from dbtable L
where L.land_id = :BLK1.LAND_ID and
L.Operatoer_id = :BLK1.Operatoer_id and
L.suppl_id = :BLK1.suppl_id and
L.suppl_prof_id = :BLK1.suppl_prof_id;
end if;
end;
Will it be able to load multiple data(20-30 at a time) to the table?
Should I write anything to commit the data in the table?
I am very new to oracle forms...please help..
