How do I generate an error condition within a Trigger? This might sound a strange request to some but I'm trying to do input validation on an insert/update query using a trigger. If the validation fails I need to set an error condition such that MySQL will not Insert/Ammend the data. Whilst I could force 'sensible' defaults in the event of validation failure I'd prefer to dump the entire record as being 'out of bounds'. The manual states that when an error occurs within a trigger the table data isn't modified which is exactly the behaviour I want. Unfortunately the manual doesn't state how to generate an error (safely).
