毫秒的存取最大計數

這裏是我的查詢：毫秒的存取最大計數

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));

這裏是輸出：

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

我想CountOfJoker的MAX與下面的輸出：

CountOfJoker GameID 
3  18

謝謝 Drew

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

答案1幾乎奏效。當有許多具有相同值的計數時，查詢將返回輸出中的許多行。但是，當我通過count（*）desc刪除順序時，它僅返回第一個計數，即使它不是最大計數。 – Drew

嘗試'ORDER BY CountOfJoker DESC'（不知道它是否適用於MS Access） – StrubT

不起作用，ms-access抱怨CountOfJoker – Drew
