Database design, how to distinguish between “RMB players” and “non-RMB players”

  mysql, question

I don’t play games. Now we need the game database design, how to distinguish between “RMB players” and “non-RMB players”, a field to come or not?

Add a field cost to the User table, or associate a money table with cost fields in the table. Cost defaults to zero when creating users, and cost increases every time you consume. OK, then judge whether RMB players, as long as cost is greater than 0.
