訪問子查詢和聚合計算

我有一個SALES RECEIPT表和一個RETURNS表。兩個表中的信息彼此獨立，但每個表都具有SALES_REP表中的Rep_ID屬性。訪問子查詢和聚合計算

在第一個子查詢中，我按月爲每個銷售人員計算SALES RECEIPT表中「總銷售額」和「總佣金」之和。

在第二個子查詢中，我按月爲每個銷售人員計算RETURNS表中的「退貨銷售」和「失業佣金」之和。

在主要查詢中，我想每個月向每個銷售人員顯示「總銷售額」，「總佣金」，「退貨銷售額」，「佣金損失」和「淨佣金」。「淨委員會」是「總委員會」減去「失業委員會」。

隨着我的代碼，我得到錯誤信息：「Microsoft Access數據庫引擎找不到輸入表或查詢‘totSales’確保它存在並且其名稱拼寫正確。」

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,

     ((Nz(SALES_RECEIPT.selling_price, 0) * Nz(SALES_RECEIPT.quantity, 0)) * (Nz(SALES_RECEIPT.commission_percent, 100) * 0.001)) AS [Gross Commission]

    INNER JOIN SALES_REP ON totSales.REP_ID = SALES_REP.rep_id 

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

下面的查詢返回月度銷售佣金數據，但只有一個銷售人員，我想上面的查詢返回完全相同的結果下面的查詢，但對所有銷售人員的不只是一個銷售人員。

您在Round（TotCommissions - TotLostCommissions，2）AS [Net Commission]後選擇的列是括號中的select語句，它返回多個字段。這在SQL中是不允許的。您將此列命名爲'totSales'，但在外部語句的FROM子句中，您將其引用爲表格 - 它不是。你想要什麼這個查詢返回？ – Leviathan

我發佈了查詢的代碼，該查詢僅返回一個銷售人員的月度佣金數據。我希望新查詢返回所有銷售人員的相同信息。 –

移動這兩個子查詢，使它們位於查詢的FROM ... JOIN部分。正如@Leviathan指出的那樣，該查詢目前正在將它們視爲字段（當然，它們不是）。

另外：請確保您包含您在GROUP BY子句中分組的所有字段（並且不要別名 - 您將收到錯誤）。

這是對第一個查詢的刺戳。訪問是扭曲它是如何喜歡當你做多加入括號，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：作爲一種風格的東西：它一般最好把逗號分隔與外地它們後面的線，多個領域如：

SELECT 
    SomeField 
    ,SomeOtherField

不是：

SELECT 
    SomeField, 
    SomeOtherField

有些人得到真正彎出它的形狀，所以可能是一個很好想法試圖養成用逗號領先的習慣，以避免不必要的批評。

最初的錯誤是：在查詢表達式'SUM（totReturns。[Return Sales]，0'）中與函數一起使用的參數數量錯誤我刪除了0，形式如下： Sum（totReturns。[Return Sales]）AS [銷售退貨]， Sum（totReturns。[Lost Commission]）AS [Lost Commission]，現在它提示：輸入參數值爲（1）totReturns.Return Sales（2）TotCommissions（3）TotLostCommissions。任何值查詢返回所有列，但「銷售退貨」和「淨佣金」列爲空 –

「總銷售額」，「總佣金」和「佣金損失」列的值遠遠高於應得值be。「月/年」和「銷售人員」列顯示正確的值。 –
