sql - 毫秒访问最大计数

Question

这是我的查询：

SELECT Count(*) AS CountOfJoker, tblPrediction.GameID
FROM (tblUser INNER JOIN (tblPool INNER JOIN tblUserPool ON tblPool.PoolID = tblUserPool.PoolID) ON tblUser.UserID = tblUserPool.UserID) INNER JOIN (tblResult INNER JOIN tblPrediction ON tblResult.GameID = tblPrediction.GameID) ON tblUser.UserID = tblPrediction.UserID
GROUP BY tblPrediction.GameID, tblPrediction.Joker, tblResult.GroupName, tblPool.PoolID
HAVING (((tblPrediction.Joker)=True) AND ((tblResult.GroupName)='A') AND ((tblPool.PoolID)=314));

这是输出：

CountOfJoker    GameID
2       1
2       2
2       9
1       10
1       17
3       18

我想要具有以下输出的 CountOfJoker 的 MAX：

CountOfJoker    GameID
3       18

谢谢德鲁

你可以使用select top和order by ... desc

    SELECT TOP 1 Count(*) AS CountOfJoker, tblPrediction.GameID
    FROM (tblUser INNER JOIN (tblPool INNER JOIN tblUserPool ON tblPool.PoolID = tblUserPool.PoolID) ON tblUser.UserID = tblUserPool.UserID) INNER JOIN (tblResult INNER JOIN tblPrediction ON tblResult.GameID = tblPrediction.GameID) ON tblUser.UserID = tblPrediction.UserID
    GROUP BY tblPrediction.GameID, tblPrediction.Joker, tblResult.GroupName, tblPool.PoolID
    HAVING (((tblPrediction.Joker)=True) AND ((tblResult.GroupName)='A') AND ((tblPool.PoolID)=314));
    ORDER BY Count(*) DESC
