刪除有一列重複的行（不是'不同'）

Question

我正在使用訪問，並試圖編寫一個查詢，它將刪除一列的重複項。這裏是我的查詢到目前爲止：

SELECT 
    Drawings.DrawingID, 
    Players.NumOfGuessedAPainting, 
    Players.NumOfGuessedBPainting, 
    Players.NumOfGuessedCPainting, 
    Words.Word 
FROM Words INNER JOIN 
    (Players INNER JOIN 
    (Drawings INNER JOIN 
    PlayersAndWords 
     ON Drawings.DrawingID = PlayersAndWords.DrawingID) 
     ON Players.PlayerID = PlayersAndWords.DrawingPlayerID) 
     ON Words.WordID = PlayersAndWords.WordID 
WHERE ((Words.Word)='" + w + "') 
ORDER BY (Players.NumOfGuessedAPainting 
     +Players.NumOfGuessedBPainting * 2 
     +Players.NumOfGuessedCPainting *3) DESC 

列Drawings.DrawingID可能被複制，我想查詢返回只有一排每個Drawings.DrawingID的。 「獨特」在這裏不起作用。我已閱讀group by可能會幫助，但我無法形容如何..
你能幫助我嗎？

在此先感謝。

Answer 1

只要把訂單之前，這些內襯一行

GROUP BY 
    Drawings.DrawingID, 
    Players.NumOfGuessedAPainting, 
    Players.NumOfGuessedBPainting, 
    Players.NumOfGuessedCPainting, 
    Words.Word 

編輯。
