Hi yogeshwar,

Take a formula column.

Select the count of one value (this should be not null value).

If COUNT(you want) is null

Return (Value/message);

end if;

Tahnks,
Chakri Smile

If my understanding is correct, you want to show a message when the total no.of records is zero.if so,you can write something like following.

Declare
num number;
Begin
select count(empno) into num from emp;
if num = 0 then
message('total Records are zero')
--or else you can define an alert and show it by using
-- show_alert() method.
end if;
End;
