Sorry, but that's very bad. There is no way that the string '2a' could
represent 0. I agree that interpreting '2a' as the integer 2 may be considered
wrong, but I think you're solving the problem the wrong way.
If you want to indicate a problem, I would like to suggest that you either
return NULL or have sqlite_step() generate an actual error code. Of the two I
think returning NULL is more within the spirit of SQL but I haven't though that
through yet.
