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?)
Okay . . . I tried OLD.
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;
Try:
end; //
delimiter ;
I just wrote the trigger source in the Trigger Editor in Database Workbench
and it doesn't bother about delimiters and such...
It also has no ";" after the final END, but hey, who knows ;-)
