Bad idea.
E.g. how do you want to warrant (integrity!) that records in
the table <table_x> point only to codes that are valid for this table.
To implement this as a constraint and at object level would create an
obfuscated mess.
Besides, that "id" column is a bad idea as well. The primary key of such
a table would have to be composed of "code" and "table_name", of course.

With any reasonable database framework that I know of, it's
ridiculously trivial to declare these codes as de-normalises "one to
many"-attributes at the object level. No need to implement *any*
"controllers" at all.
