That's a very poor design because it's both denormalized and has very
poor naming.  There are likely plenty of other things wrong with it,

suspect it won't take long to find some.

Nothing will really help until you fix your design, and dynamic
querying will only lead you further down this rat-hole.

The answer to, "how do I shoot myself in the foot?" is "Don't."
