creating error from trigger alert
If all I want to do is create an error, how will this be done?
Here is my trigger:
SELECT * FROM `lead_email` WHERE 1
create trigger insert_lead_email
before insert on lead_email
for each row
begin
set @leadid;
set @gc_id=new.gc_id;
select NEW.`lead_id`=lead_id from lead where Email=new.gc_SenderEmailAd
if NEW.lead_id is NULL THEN
END IF
update lead
lead_id=@leadid
set
where
gc_id=@gc_id;
end

is lead_id a not null column? if so then you can define an exit handler when it encounters a null. See http://dev.mysql.com/doc/refman/5.1/en/declare-handler.html for reference on handlers.
http://flylib.com/books/en/1.142.1.62/1/ gives a good explanation on creating handlers. sorry to only give you links - only on an ipad right now and i dont want to give you code i haven't tested

Thanks for the links. Is it possible for you to actually check the code and post? I am trying to work this out :)
Busy right now but I think I can look at it later. Can you confirm that lead_id is a not null column or if not can you make it so?

I can make it null. . no problem.
