好的我有一个包含以下字段的表：

correct_id，player_id，奖励

我想按照谁拥有最正确的答案，他们获得了多少问题以及他们获得的总奖励的降序创建一个列表。我该怎么做？

SELECT player_id, sum(correct_id), sum(reward) FROM questions_correct GROUP BY count(correct_id)

Answer 1

试试这个：

SELECT player_id, COUNT(correct_id) CorrectAnsCnt, SUM(correct_id), SUM(reward) 
FROM questions_correct 
GROUP BY player_id
ORDER BY CorrectAnsCnt DESC
