SQL服務器中的UNION和GROUP BY

Question

我需要幫助才能在SQL Server中創建視圖。我有這樣

SELECT MemberId, 
      Name, 
      SUM(TotalSales) as SalesAmount, 
      CreatedOn 
    FROM (
      (SELECT MAX(0) AS MemberId, 
        MAX('Others') AS Name, 
        SUM(TotalSales) AS SalesAmount, 
        CreatedOn 
       FROM {...} AS A 
       GROUP BY CreatedOn 
      ) 
      UNION 
      (SELECT MemberId, 
        Name, 
        SUM(TotalSales) AS SalesAmount, 
        CreatedOn 
       FROM {...} AS D 
       GROUP BY MemberId, Name, CreatedOn    
     ) 
    ) AS E 
    GROUP BY MemberId, Name, CreatedOn 

但是當我保存視圖，在Microsoft SQL Server管理給我這個錯誤的一些事情：

誰能幫幫我好嗎？ 在此先感謝

我認爲你正在尋找的東西是這樣的：

SELECT MemberId, Name, SUM(SalesAmount) as SalesAmount, CreatedOn 
FROM ( 
    SELECT MAX(0) AS MemberId, 
      MAX('Others') AS Name, 
      SUM(TotalSales) AS SalesAmount, CreatedOn 
    FROM 
     {...} AS A 
    GROUP BY CreatedOn 

    UNION 

    SELECT MemberId, Name, 
      SUM(TotalSales) AS SalesAmount, CreatedOn 
    FROM 
     {...} AS D 
    GROUP BY MemberId, Name, CreatedOn    

) AS E 
GROUP BY MemberId, Name, CreatedOn
