访问子查询和聚合计算

Question

我有一个SALES RECEIPT表和一个RETURNS表。两个表中的信息彼此独立，但每个表都具有SALES_REP表中的Rep_ID属性。

在第一个子查询中，我按月为每个销售人员计算SALES RECEIPT表中“总销售额”和“总佣金”之和。

在第二个子查询中，我按月为每个销售人员计算RETURNS表中的“退货销售”和“失业佣金”之和。

在主要查询中，我想每个月向每个销售人员显示“总销售额”， “总佣金”，“退货销售额”，“佣金损失”和“净佣金”。 “净委员会”是“总委员会”减去“失业委员会”。

随着我的代码，我得到错误信息：“Microsoft Access数据库引擎找不到输入表或查询‘totSales’确保它存在并且其名称拼写正确。”

Select 
    totSales.Year-Month as [Month/Year], 
    SALES_REP.rep_name as [Sales Person], 
    SUM(totSales.[Total Sales]) as [Total Sales], 
    SUM(totSales.[Gross Commission]) as [Gross Commission], 
    SUM(totReturns.[Return Sales],0) as [Sales Returns], 
    SUM(totReturns.[Lost Commission],0) as [Lost Commission], 
    Round([Gross Commission] - [Lost Commission],2) AS [Net Commission], 


    (SELECT 
     Format(SALES_RECEIPT.sale_date,'yyyy-mm') AS [Year-Month], 
     SALES_RECEIPT.rep_id, 
     (SALES_RECEIPT.selling_price * SALES_RECEIPT.quantity) AS [Total Sales], 
     ((Nz(SALES_RECEIPT.selling_price, 0) * Nz(SALES_RECEIPT.quantity, 0)) * (Nz(SALES_RECEIPT.commission_percent, 100) * 0.001)) AS [Gross Commission] 
    FROM 
     SALES_RECEIPT 
    WHERE 
     SALES_RECEIPT.sale_date Between #1/1/2000# And #12/31/2050#) AS totSales, 


    (SELECT 
     RETURNS.rep_id, 
     (Nz(RETURNS.selling_price * RETURNS.quantity)) AS [Sales Returns],

From (totSales

    INNER JOIN SALES_REP ON totSales.REP_ID = SALES_REP.rep_id 

Group By totSales.Year-Month, totSales.rep_name; 

下面的查询返回月度销售佣金数据，但只有一个销售人员，我想上面的查询返回完全相同的结果下面的查询，但对所有销售人员的不只是一个销售人员。

SELECT Format(DatePart("m",months.month_start),"00") & "/" & Year(months.month_start) AS [Month/Year],

移动这两个子查询，使它们位于查询的FROM ... JOIN部分。正如@Leviathan指出的那样，该查询目前正在将它们视为字段（当然，它们不是）。

另外：请确保您包含您在GROUP BY子句中分组的所有字段（并且不要别名 - 您将收到错误）。

这是对第一个查询的刺戳。访问是扭曲它是如何喜欢当你做多加入括号，所以道歉，如果它不工作的第一次：

Select 
    totSales.Year-Month as [Month/Year], 
    SALES_REP.rep_name as [Sales Person], 
    SUM(totSales.[Total Sales]) as [Total Sales], 
    SUM(totSales.[Gross Commission]) as [Gross Commission], 
    SUM(totReturns.[Return Sales],0) as [Sales Returns], 
    SUM(totReturns.[Lost Commission],0) as [Lost Commission], 
    Round(TotCommissions - TotLostCommissions,2) AS [Net Commission] 

FROM 
    SALES_REP 
INNER JOIN 
    (
    (SELECT 
     Format(SALES_RECEIPT.sale_date,'yyyy-mm') AS [Year-Month], 
     SALES_RECEIPT.rep_id, 
     (SALES_RECEIPT.selling_price * SALES_RECEIPT.quantity) AS [Total Sales], 
     ((Nz(SALES_RECEIPT.selling_price, 0) * Nz(SALES_RECEIPT.quantity, 0)) * (Nz(SALES_RECEIPT.commission_percent, 100) * 0.001)) AS [Gross Commission] 
    FROM 
     SALES_RECEIPT 
    WHERE 
     SALES_RECEIPT.sale_date Between #1/1/2000# And #12/31/2050#) AS totSales 
LEFT JOIN 
    (SELECT 
     RETURNS.rep_id, 
     (Nz(RETURNS.selling_price * RETURNS.quantity)) AS [Returns Sales], 
     ((Nz(RETURNS.selling_price, 0) * Nz(RETURNS.quantity, 0)) * (Nz(RETURNS.commission_percent, 100) * 0.001)) AS [Lost Commission] 
    FROM 
     RETURNS 
    WHERE 
     RETURNS.return_date Between #1/1/2000# And #12/31/2050#) As totReturns 
on totReturns.rep_id = totSales.rep_id 
) 
ON totSales.REP_ID = SALES_REP.rep_id 

Group By 
    totSales.Year-Month 
    ,SALES_REP.rep_name 
    ,Round(TotCommissions - TotLostCommissions,2) 
; 

另外：作为一种风格的东西：它一般最好把逗号分隔与外地它们后面的线，多个领域如：

SELECT 
    SomeField 
    ,SomeOtherField 

不是：

SELECT 
    SomeField, 
    SomeOtherField 

有些人得到真正弯出它的形状，所以可能是一个很好想法试图养成用逗号领先的习惯，以避免不必要的批评。
