This advanced SQL exercise is part of the book: Advanced SQL – Practical Techniques and Use-Cases, which includes 100 day-to-day SQL challenges (and solutions), need-to-know advanced features, and key concepts.
Given a table that displays players, and various possibilities for games in which every player can take part (each player can participate in 3 different games).
The main difference between this table and the table included in the previous exercise lies in the options each player has.

CREATE TABLE players (playerID varchar(25), gameID varchar(25)) GO
