Question

I have a table with game scores, allowing multiple rows per account id: scores (id, score, accountid). I want a list of the top 10 scorer ids and their scores.

Can you provide an sql statement to select the top 10 scores, but only one score per account id?

Thanks!

Answer 1

First limit the selection to the highest score for each account id. Then take the top ten scores.

SELECT TOP 10 AccountId, Score FROM Scores s1 WHERE AccountId NOT IN      (SELECT AccountId s2 FROM Scores       WHERE s1.AccountId = s2.AccountId and s1.Score > s2.Score) ORDER BY Score DESC
