Question

I am creating a MySQL database for quiz bowl. The design is to have a cross table containing all game results, the cross table having the form:

CREATE TABLE game_results(
  id SMALLINT NOT NULL AUTO_INCREMENT PRIMARY KEY,
  game_id MEDIUMINT NOT NULL,
  team_id SMALLINT NOT NULL,
  score MEDIUMINT);

My question is how does one count the number of wins a team has (that is, the number of times a team is the highest scoring team in a particular game) from the table game_results using MySQL.

Answer 1

SELECT COUNT(1) AS wins FROM game_results AS gr1
LEFT JOIN game_results AS gr2 ON gr1.game_id=gr2.game_id AND gr2.team_id != 1234
WHERE gr1.team_id = 1234 AND gr1.score > gr2.score
