hey guys,
I would like to disallow an insert into a table but without any error message showing...
CREATE OR REPLACE TRIGGER no_trade
before insert on br_orders_trig
for each row
declare
p_atype number; /* Account type 1/0 if 1 then paper trade */
begin
select account_type into p_atype from br_account where account_id=:new.account_id;
if p_atype=1 then
:new.order_status:=-2;
raise_application_error(-20001,'Just Paper Trade...');
end if;
end;
Fortunately the above stops the insert but am left with an ugly message. I would like the user to continue without seeing an error.
Please Help...
Thanks in advance.
ALEX

it is not possible to stop error being displayed when you issue insert statement from sqlplus. but you can supress that message from calling program
ex:
declare
x exception;
pragma exception_init(x,-20001);
begin
insert into table1 values('kkk');
exception
when x then
null;
end;
or
if you are issuing this sql statement from client program, suppress that message using sqlcode.
