In that case your database design is fundamentally broken. A database
should have content fields that map to the needs of the application.
As you describe your application requirements, that is a bit string
and not an integer. Use bit strings and your application logic is
transparent, obvious and easy to maintain. Use integers and you have
to resort to "magic". As you say, it's your choice, but you came here
looking for advice and the advice you were given is very good....
