Question

I’m trying to create this trigger and I get this error:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'case where artcStackId = new.artcStackId' at line 7

Here is the failing trigger

SET new.artcPublicId = 
 case 
 when new.artcCountry = 'US' then concat(91,new.artcStackId)
 when new.artcCountry = 'UK' then concat(92,new.artcStackId)
 when new.artcCountry = 'CA' then concat(93,new.artcStackId)
 else concat(11,new.artcStackId)
 end case
 where artcStackId = new.artcStackId

Here is the trigger that works

SET new.artcPublicId = 
case 
when new.artcCountry = 'US' then concat(91,new.artcStackId)
when new.artcCountry = 'UK' then concat(92,new.artcStackId)
when new.artcCountry = 'CA' then concat(93,new.artcStackId)
else concat(11,new.artcStackId)
end

when I add those extra bits, it’ll fail.

There is no reference to your where condition.i think it should be like where new.artcStackId = new.artcStackId
