我需要您提供有关Sql查询的帮助。我正在尝试实施两张牌的点数概念。所以我创建了一个名为MargePoints的参考表，并将CardIDs（CardDetails表的主键）保存为CardID和MargedID.After Points marged，我试图在一行中显示CardID和MargedID的所有信息。向我发送相关表格和查询的脚本。

SELECT MargePointsID,
       DOC,
       AdminName,
       MargedPoints,
       CardNumber,
       CustomerName,
       CardNumber2,
       CustomerName2 
FROM (

       SELECT   MargePoints.MargePointsID,  
                MargePoints.DOC, 
                AdminUsers.AdminName, 
                MargePoints.MargedPoints, 
                CardDetails.CardNumber, 
                CustomerDetails.CustomerName,
                '' AS CardNumber2 ,
                '' AS CustomerName2 

        FROM AdminUsers 
        INNER JOIN MargePoints ON AdminUsers.AdminUserID = MargePoints.AdminID 
        INNER JOIN CustomerDetails 
        INNER JOIN CardDetails ON CustomerDetails.CardID = CardDetails.CardID ON MargePoints.MargedID = CardDetails.CardID 

        UNION ALL 

        SELECT  MargePoints.MargePointsID,
                MargePoints.DOC, 
                AdminUsers.AdminName,
                MargePoints.MargedPoints,
                '' AS CardNumber ,
                '' AS CustomerName, 
                CardDetails.CardNumber AS CardNumber2,
                CustomerDetails.CustomerName AS CustomerName2 
         FROM AdminUsers 
         INNER JOIN MargePoints ON AdminUsers.AdminUserID = MargePoints.AdminID 
         INNER JOIN CustomerDetails 
         INNER JOIN CardDetails ON CustomerDetails.CardID = CardDetails.CardID ON MargePoints.CardID = CardDetails.CardID
