- The command above, does not insert the last_seq into users.code column.
And I don't know why.
If I comment the line: *ELSEIF NEW.code IS NULL THEN*, the data is inserted
into the users.code column.
But as the customer can add data into that column, I only insert the
last_seq if he/she didn't insert anything.
So I need that *ELSEIF NEW.code IS NULL THEN*.
- What am I missing?
Thanks
Lucas
