Test this assumption before doing any work based on it.  Some of the 
reasons I'm skeptical:

- I don't see mention any such behavior in the MySQL C API docs

- I think I'd remember if MySQL++ cleared the error number itself

- Not all BadQuery exceptions carry the return value of 
Connection::error() as the message, so if you're catching one of those, 
the error number would already be meaningless

If you're going to do this, add it to every exception where it makes sense.
