Drive MYSQL directories with% date% (minecraft)?

I have a directory in the directories in MYSQL:

Username

Bank
Coins

In the score board which is the same plugin where the coins are coming from% coins% of the coins stood% bank% does not go though they are both in the same user directory. How can I access the data from the other directory? Because username / bank username_bank and username% bank are not.

Do I need a PlaceholderAPI and if so how do I get all the data there?
