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'
Query
= 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
)
It looks like I can't do what I want to do . . . get the jobpost_id to
check jobpost and adsource tables BEFORE proceeding to delete the
record. If so, what's the best way to do this?
