Question

I have a very simple database consisting of these tables. Here I am trying to write a query to select the player who played in the most games from the Games table.

Just by looking at the below example you can tell that the answer is Ben of course, because PID 2 (which is Ben from the Players table) appears the most times in the Games table, meaning Ben won the most games.

But I am not sure how to write the query for selecting the most recurring value in the Games table.

Players         Games          

PID | name      GID | PID
----|-----      ----|------
1   |  Al       A   |  3
2   |  Ben      A   |  2
3   |  Carl     A   |  2
4   |  Jack     A   |  1
5   |  Ron      A   |  4

Does anyone have any suggestions? Thanks!

Answer 1

Well, join players and games, count, group by player, order by count desc (greatest first), and limit to one if you want the first.

SELECT p.NID, p.name, COUNT(*)
FROM Players p
INNER JOIN Games g ON g.PID= p.NID
GROUP BY p.NID, p.name
ORDER BY COUNT(*) DESC
LIMIT 1;
