The best solution in your situation is to bring your table to the third
normal form. I cannot tell you very much detail, because cat1-3 is is
the only thing I know about your table. The idea is that you should
design your table is such a way that if one person has a relationship
with more than one category, you would have a row per category. You
should probably have a separate person_cat table, and join it with the
main one when needed.
