Hi,

What is the exact error message?


Here's the latest query:

delimiter //
create trigger jobposts_control
 before delete on jobposts for each row
begin
   declare dummy varchar(255);
   set @counted = (
       select count(ad.adsource_id)
       from adsource ad, jobposts jp
       where ad.adsource_id = jp.adsource_id
       and old.jobpost_id = jp.jobpost_id
   );
   if @counted >= 1 then SET dummy = "Cannot delete this record"; end if;
end //
delimiter ;

Here's the error message:

ERROR: Unknown column 'old.jobpost_id' in 'where clause'

Works fine here (although with different tables).

Just for fun and giggles, have you tried OLD. (uppercase?)

As a complete sidenote:

It's better to write your JOINs with a JOIN clause and to put your
strings inside single quotes as per SQL standard, double quotes are
really for object names.
