Re: How to Raise Error ?
Hi!
this is currently not possible in a clean way. Proper support for raising errors is added in 6.1 (alpha - development tree)
You can work around it by causing a runtime error in some other way. If your table has some not nullable columns, the easiest way is to set those to NULL in case you detect invalid input. If you do that in the BEFORE trigger, the trigger will fail due to the NOT NULL constraint violation.
Of course, its ugly because the client cannot discern between a real NOT NULL violation and this deliberate action. You can work around that by setting a user-defined variable to indicate what really happened.
I know it is ugly but this is unfortunately the best you can do atm.
regards,
Roland.
