MS Access Union，排序依據弄亂了我的查詢順序

Question

SQL：

SELECT 
    SUM(dbo_SO_SalesHistory.DollarsSold) AS SumDollarsSold,  
    "PHOA" As CustomerNo
FROM  
    dbo_SO_SalesHistory
WHERE 
    ((dbo_SO_SalesHistory.[CustomerNo]) IN ("PHOM","PHOB", "PHOA", "HOMP")) 
    AND ((dbo_SO_SalesHistory.InvoiceDate) BETWEEN [BeginDate] AND [EndDate])

UNION

SELECT TOP 9 
    SUM(DollarsSold), CustomerNo 
FROM 
    dbo_SO_SalesHistory
WHERE 
    ((dbo_SO_SalesHistory.CustomerNo) NOT IN ("PHOM","PHOB", "PHOA", "HOMP")) 
    AND ((dbo_SO_SalesHistory.InvoiceDate) BETWEEN [BeginDate] AND [EndDate])
GROUP BY 
    dbo_SO_SalesHistory.CustomerNo 
ORDER BY 
    1 DESC;

當我分別運行兩個查詢時，查詢的第二部分將返回我期望的輸出：

但是當我將它與UNION一起運行時，順序卻以某種方式混淆了：

。

在代碼ORDER BY 1 DESC ， 1表示第一列，即總和。

我努力了

ORDER BY SUM(dbo_SO_SalesHistory.DollarsSold) DESC;

而是返回一個錯誤：

錯誤 3

任何建議將不勝感激！

更新 ：這是當前查詢輸出：

[ ]

所需的輸出如下所示：

（我從圖片1中剪切並粘貼了2〜10行）。 希望這對您的理解有所幫助！

我當前的查詢：

Sum of Dollar | Customer
--------------+----------
     10       |    A   
      8       |    B
      1       |    Q

所需的查詢輸出

14 | B_Total
10 | A
 5 | C

B_Total（14）是X（4），Y（3），Z（2）和B（5）的總和

更新：當前查詢

SELECT 
    SumDollarsSold, CustomerNo, MyOrder 
FROM 
    (SELECT 
         SUM(dbo_SO_SalesHistory.DollarsSold) AS SumDollarsSold, 
         "PHOALLE" AS CustomerNo, 1 AS MyOrder
     FROM 
         dbo_SO_SalesHistory
     WHERE 
         ((dbo_SO_SalesHistory.[CustomerNo]) IN ("PHOMIN","PHOALLE","PHOBROO","PHOMP"))  
         AND ((dbo_SO_SalesHistory.InvoiceDate) Between [BeginDate] And [EndDate])
     UNION
     SELECT TOP 9 
         SUM(DollarsSold), CustomerNo, 2 as MyOrder 
     FROM 
         dbo_SO_SalesHistory
     WHERE 
         ((dbo_SO_SalesHistory.CustomerNo) NOT IN ("PHOM","PHOA","PHOB","PHOM")) 
         AND ((dbo_SO_SalesHistory.InvoiceDate) Between [BeginDate] And [EndDate])
     GROUP BY 
         dbo_SO_SalesHistory.CustomerNo
     ORDER BY 
         1 DESC
) a 
ORDER BY 
    MyOrder, SumDollarsSold DESC;

Answer 1

當您使用UNION時，無法保證任何訂單，因此您將丟失在第二個查詢中已經完成的ORDER BY。 您可以添加另一個字段，以確保第一條記錄始終位於最前面，但是您確實需要將其包括在所選字段中。 像這樣：

SELECT 
    SumDollarsSold, CustomerNo, MyOrder 
FROM 
    (SELECT 
         SUM(dbo_SO_SalesHistory.DollarsSold) AS SumDollarsSold, 
         "PHOA" AS CustomerNo, 1 AS MyOrder
     FROM 
         dbo_SO_SalesHistory
     WHERE 
         ((dbo_SO_SalesHistory.[CustomerNo]) IN ("PHOM","PHOB", "PHOA", "PHOM"))  
         AND ((dbo_SO_SalesHistory.InvoiceDate) Between [BeginDate] And [EndDate])
     UNION
     (SELECT TOP 9 
         SUM(DollarsSold), CustomerNo, 2 as MyOrder 
     FROM 
         dbo_SO_SalesHistory
     WHERE 
         ((dbo_SO_SalesHistory.CustomerNo) NOT IN ("PHOM","PHOB", "PHOA", "PHOM")) 
         AND ((dbo_SO_SalesHistory.InvoiceDate) Between [BeginDate] And [EndDate])
     GROUP BY 
         dbo_SO_SalesHistory.CustomerNo
     ORDER BY 
         SUM(DollarsSold) DESC)
) a 
ORDER BY 
    MyOrder, SumDollarsSold DESC;
