I've been thinking about this for quite some time now but I'm still not
sure. The question is, is there a way for insert/delete/update to affect 0
rows other than the where clause giving a condition that is not satisfiable.

Of course this can happen via constraints but then the backend will return
an error message so I know the difference.
