删除有一列重复的行（不是'不同'）

Question

我正在使用访问，并试图编写一个查询，它将删除一列的重复项。这里是我的查询到目前为止：

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可能被复制，我想查询返回只有一排每个Drawings.DrawingID的。 “独特”在这里不起作用。我已阅读group by可能会帮助，但我无法形容如何..
你能帮助我吗？

在此先感谢。

只要把订单之前，这些内衬一行

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