hello to all
guy's i m writing this when-validate-item trigger:-

declare
cursor c is select distinct payperiod from tatrans
where empno=:tatrans.empno;
v varchar2(6);
n number;
begin
open c;
loop
fetch c into v;
if v=:tatrans.payperiod
then
n:=show_alert('alert114');
exit when c%notfound;
end if;
end loop;
end;

this trigger is working but what i want is that if the alert exists then my cursor should
get trapped into the payperiod item until the user cancel's the value or change it
please tell me how could i do this
please help me

raise form_trigger_failure.

And you don't need a loop for this - just add the if check as a where clause in the cursor.

I would have thought that was fairly obvious - you're checking if the payperiod in the datablock matches the payperiod in the database table - add that check to the where clause.
Then you can just open, fetch, close instead of looping.
