Question

我正在寻找让ACCESS查询返回结果多年的方法。由于查询中存在聚合计算，因此将BETWEEN语句更改为年份范围会导致错误。我可以使用UNION语句并重复每年的代码，但这不是非常有效。可以只使用SQL代码完成，还是必须使用VB。我不懂VB，所以如果答案是需要VB，我会很感激详细信息。

ACCESS查询的代码如下：

SELECT DISTINCT
    DatePart("yyyy",sale_date) AS [YEAR],

    (SELECT Round(Nz(Sum(sales_receipt.SELLING_PRICE * sales_receipt.quantity),0) ,2)

     INNER JOIN INVENTORY ON INVENTORY.INVENTORY_ID = SALES_RECEIPT.INVENTORY_ID
     WHERE SALES_RECEIPT.[SALE_DATE] Between #1/1/2009# And #12/31/2009#) AS [Gross Sales],

    (SELECT Round(Nz(Sum((Nz(inventory.VENDOR_ACTUAL_PRICE,0))*sales_receipt.quantity),0),2)

Answer 1

原则上，您需要使用与外部查询相关的条件替换子查询中的所有Between #1/1/2009# And #12/31/2009#条件。
如果按原样执行，您将获得一个完全低效的查询，该查询将计算外部查询中每个单独记录的总计。

在这种情况下，除了为您提供单年编号（2009）之外，您似乎没有使用外部查询。

因此，将外部查询更改为仅返回感兴趣的年份数，并使子查询相关，例如

SELECT
    Year(years.year_start) AS [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 years.year_start and years.year_end) 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 years.year_start and years.year_end) AS COGS,

    etc
FROM
    (select
         DateSerial(Year(sale_date), 1, 1) as year_start,
         DateSerial(Year(sale_date), 12, 31) as year_end
     from SALES_RECEIPT
     where sale_date between #1/1/2009# And #12/31/2015#
     group by Year(sale_date)
    ) as years

Answer 2

考虑删除外部聚合查询的WHERE子句，该子句筛选2009日期，并使每个子查询与不同的sale_date年份相关。不需要BETWEEN条款，但使用DatePart("yyyy", ...)，这将对应SALES_RECIEPT表中的每个不同年份。以下是前三个子查询的调整：

SELECT DISTINCT
    DatePart("yyyy", SALES_RECEIPT.sale_date) AS [YEAR],

    (SELECT Round(Nz(Sum(sub1.SELLING_PRICE * sub1.quantity),0) ,2) 
     FROM SALES_RECEIPT AS sub1
     INNER JOIN INVENTORY ON INVENTORY.INVENTORY_ID = sub1.INVENTORY_ID
     WHERE DatePart("yyyy", sub1.[SALE_DATE]) =  
           DatePart("yyyy", SALES_RECEIPT.sale_date)) As [Gross Sales],

    (SELECT Round(Nz(Sum((Nz(inventory.VENDOR_ACTUAL_PRICE,0)) * sub2.quantity),0),2) 
     FROM SALES_RECEIPT As sub2
     INNER JOIN INVENTORY ON INVENTORY.INVENTORY_ID = sub2.INVENTORY_ID
     WHERE DatePart("yyyy", sub2.SALES_RECEIPT.[SALE_DATE]) = 
           DatePart("yyyy", SALES_RECEIPT.sale_date)) AS COGS,

    (SELECT Round(Nz(Sum(sub3.SELLING_PRICE * sub3.quantity),0) - 
            Nz(Sum(inventory.VENDOR_ACTUAL_PRICE * sub3.quantity),0),2) 
     FROM SALES_RECEIPT As sub3
     INNER JOIN INVENTORY ON INVENTORY.INVENTORY_ID = sub3.INVENTORY_ID
     WHERE DatePart("yyyy", sub3.sale_date) =  
           DatePart("yyyy", SALES_RECEIPT.[SALE_DATE])) AS [Sales Margin],

    ...

FROM
    INVENTORY
    INNER JOIN SALES_RECEIPT ON INVENTORY.INVENTORY_ID = SALES_RECEIPT.INVENTORY_ID
GROUP BY
    DatePart("yyyy", SALES_RECEIPT.sale_date);

查询将循环一系列年份
