Question

我正在寻找一种让ACCESS查询返回一年中每个月的每月汇总计算的方法。

现在我使用UNION语句每月重复下面的代码，但这不是非常有效，我必须为每年创建一个单独的查询。

我最近问了一个类似的问题，关于如何获得查询返回年度汇总计算多年，并收到了两个很好的解决方案。几个月我尝试修改这些解决方案，但我无法让它工作。

我非常感谢每月汇总计算的解决方案。

SELECT DISTINCT
    Format(DatePart("m",sale_date),"00") & " / " & DatePart("yyyy",sale_date) AS [Month / Year], 

  (SELECT Round(Nz(Sum(sales_receipt.SELLING_PRICE * sales_receipt.quantity),0) ,2) 
    FROM SALES_RECEIPT
    INNER JOIN INVENTORY ON INVENTORY.INVENTORY_ID = SALES_RECEIPT.INVENTORY_ID
    WHERE SALES_RECEIPT.[SALE_DATE] Between #1/1/2014# And #1/31/2014#) AS [Gross Sales], 

  (SELECT Round(Nz(Sum((Nz(inventory.VENDOR_ACTUAL_PRICE,0))*sales_receipt.quantity),0),2) 
    FROM SALES_RECEIPT
    INNER JOIN INVENTORY ON INVENTORY.INVENTORY_ID = SALES_RECEIPT.INVENTORY_ID
    WHERE SALES_RECEIPT.[SALE_DATE] Between #1/1/2014# And #1/31/2014#) AS COGS,

  (SELECT Round(Nz(Sum(sales_receipt.SELLING_PRICE * sales_receipt.quantity),0) - Nz(Sum(inventory.VENDOR_ACTUAL_PRICE * sales_receipt.quantity),0),2) 
    FROM INVENTORY 
    INNER JOIN SALES_RECEIPT ON INVENTORY.INVENTORY_ID = SALES_RECEIPT.INVENTORY_ID
    WHERE SALES_RECEIPT.[SALE_DATE] Between #1/1/2014# And #1/31/2014#) AS [Sales Margin]

FROM 
    INVENTORY INNER JOIN SALES_RECEIPT ON INVENTORY.INVENTORY_ID = SALES_RECEIPT.INVENTORY_ID
    WHERE (((SALES_RECEIPT.SAle_date) Between #1/1/2014# And #1/31/2014#))
GROUP BY
    Format(DatePart("m",sale_date),"00") & " / " & DatePart("yyyy",sale_date)

您需要进行查询以获取您的值并进行计算，然后将其包含在子查询中以进行聚合。试试这个（未经测试）：

SELECT a.[Sale Month], 
    a.[Sale Year],
    ROUND(SUM(a.[Gross Sales]),2) AS [Gross Sales],
    ROUND(SUM(a.[COGS]),2) AS [COGS],
    ROUND(SUM(a.[Sales Margin]),2) AS [Sales Margin],
    Round((Sum(a.[Sales Margin])/Sum([Gross Sales]))/100,2) AS [Profit Margin]
FROM
    (
    SELECT
        Format(DatePart("m",s.sale_date),"00") AS [Sale Month], 
        DatePart("yyyy",s.sale_date) AS [Sale Year], 
        Nz(s.SELLING_PRICE * s.quantity,0) AS [Gross Sales], 
        Nz(i.VENDOR_ACTUAL_PRICE,0)*Nz(s.quantity,0) AS [COGS],
        Nz(s.SELLING_PRICE * s.quantity,0) - Nz(i.VENDOR_ACTUAL_PRICE * s.quantity,0) AS [Sales Margin]                                            
    FROM 
        INVENTORY i
        INNER JOIN SALES_RECEIPT s ON i.INVENTORY_ID = s.INVENTORY_ID
    WHERE DatePart("m",sale_date) = 1
        AND DatePart("yyyy",sale_date) = 2014
    ) a
GROUP BY a.[Sale Month], a.[Sale Year]
ORDER BY a.[Sale Year], a.[Sale Month]

只需删除或更改WHERE子句即可扩展分组。

以下是基于您的问题的更新。您可以看到如何修改WHERE语句以允许更大的范围。您还可以看到[Month / Year], [Sale Month],和[Sale Year]列在GROUP BY语句中的显示方式，[Month / Year]字段中显示的SELECT字段以及{{ 1}}和[Sale Month],字段显示在[Sale Year]语句中。一个用于展示，另外两个用于正确排序。

ORDER BY
