Top 3 uit Mysql-tabel halen op basis van conditie/waarde

Nou, je kunt deze query-set proberen:

(SELECT Name, PositionId, TScore FROM Soccerplayers WHERE PositionID = 1 ORDER BY TScore LIMIT 3)
UNION
(SELECT Name, PositionId, TScore FROM Soccerplayers WHERE PositionID = 2 ORDER BY TScore LIMIT 4)
UNION
(SELECT Name, PositionId, TScore FROM Soccerplayers WHERE PositionID = 3 ORDER BY TScore LIMIT 3)
