Not sure what your intentions are, but note that most folks here will recommend against interacting directly with the database.

Yep.  Reading it is a bit of a nightmare, and you absolutely can't write.

If you explained why you are asking, there's a very good chance someone here can give you a much better way to achieve your goal.
