I have two tables
Games and Scores:
games has a primary key ID
Scores has game_id which references games.id and created on among other fields.
i am attempting to adapt the second example in the accepted answer of this question to fit my needs.
SELECT g.*,
s.*
FROM GAMES g
LEFT JOIN SCORES s ON s.game_id = g.id
JOIN (SELECT n.game_id,
MAX(n.created_on) AS max_score_date
FROM SCORES n
GROUP BY n.game_id) y ON y.game_id = s.game_id
AND y.max_score_date = s.created_on
it almost works, it gets the most recent entry in the score table for each game. however it only returns games which have a corresponding entry in the score table. and i need it to return all games in the table reguardless of if they have a entry in the score table. which from reading the previously cited question i assumed that the left join would accomplish.
