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;

当我单独运行两个查询时，查询的第二部分返回我期望的输出：

但是当我与UNION一起运行时，订单会以某种方式混淆：

。

在代码ORDER BY 1 DESC中，1指的是第一列，即总和。

我试过了

ORDER BY SUM(dbo_SO_SalesHistory.DollarsSold) DESC;

相反，它会返回错误：

Err 3

任何建议都将受到高度赞赏！

更新：这是当前的查询输出：

所需的输出如下：

（我从图片1中剪切并粘贴了2~10行）。我希望这有助于您的理解！

我当前的查询：

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

所需的查询输出

14 | B_Total
10 | A
 5 | C

B_Total（14）是X（4），Y（3），Z（2）和B（5）之和

更新：当前查询

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;

当你UNION没有保证订单时，你丢失了你在第二个查询上已经完成的ORDER BY。您可以添加另一个字段以确保第一条记录始终位于顶部，但是您确实需要在所选字段中包含该字段。像这样：

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;

MS Access Union，Order By搞乱我的查询订单
