Question

我想查询SUMS一组月份（即5月 - 8月）每个产品ID的总销售数量

我想：

+------------+-------------------------+-------+--------------+-----------------+
| PRODUCT_ID |          ITEM           | PRICE | GROSS_MARGIN | Sum Of QUANTITY |
+------------+-------------------------+-------+--------------+-----------------+
| 100-10     | ALVE laptop table       |    89 | 56%          |           23323 |
| 100-15     | FREDRIK desk            |   129 | 44%          |            9614 |
| 100-20     | GALANT conference table |   369 | 32%          |           10272 |
+------------+-------------------------+-------+--------------+-----------------+

但是我无法设置查询来执行此操作，因为我很难访问（真的是我第一次玩弄它）。

这是我当前的查询吐出的内容：

+------------+--------------------------+---------+--------------+--------------------+----------+
| PRODUCT_ID |           ITEM           |  PRICE  | GROSS_MARGIN | TRANSDATE By Month | QUANTITY |
+------------+--------------------------+---------+--------------+--------------------+----------+
| 100-10     | ALVE laptop table        | $89.00  | 56.00%       | August 2011        |     9679 |
| 100-10     | ALVE laptop table        | $89.00  | 56.00%       | July 2011          |     9436 |
| 100-10     | ALVE laptop table        | $89.00  | 56.00%       | June 2011          |     3222 |
| 100-10     | ALVE laptop table        | $89.00  | 56.00%       | May 2011           |      986 |
| 100-15     | FREDRIK desk             | $129.00 | 44.00%       | August 2011        |     3150 |
| 100-15     | FREDRIK desk             | $129.00 | 44.00%       | July 2011          |     2695 |
| 100-15     | FREDRIK desk             | $129.00 | 44.00%       | June 2011          |     3769 |
| 100-20     | GALANT conference table  | $369.00 | 32.00%       | August 2011        |     3814 |
| 100-20     | GALANT conference table  | $369.00 | 32.00%       | July 2011          |     4977 |
| 100-20     | GALANT conference table  | $369.00 | 32.00%       | June 2011          |      225 |
| 100-20     | GALANT conference table  | $369.00 | 32.00%       | May 2011           |     1256 |
+------------+--------------------------+---------+--------------+--------------------+----------+

基本上，我想要一行来总结那4个月（5月到8月，包括每月的每一天）的项目的所有销售额。如有必要，请忽略其他列（价格和保证金）。

任何帮助将不胜感激，我需要在星期五之前完成！已经玩了好几个小时，但每次我走得更近，我似乎都会打破一些东西。：'（

这是我当前的SQL语法/代码（抱歉，不知道正确的术语）。

SELECT DISTINCTROW 
     PRODUCTS.PRODUCT_ID, 
     PRODUCTS.ITEM, 
     PRODUCTS.PRICE, 
     PRODUCTS.GROSS_MARGIN,
     Format$([SALES].[TRANSDATE],'mmmm yyyy') AS [TRANSDATE By Month], 
     Sum(SALES.QUANTITY) AS [Sum Of QUANTITY]
FROM PRODUCTS INNER JOIN 
     SALES ON PRODUCTS.[PRODUCT_ID] = SALES.[PRODUCT_ID]
GROUP BY 
     PRODUCTS.PRODUCT_ID, 
     PRODUCTS.ITEM, 
     PRODUCTS.PRICE, 
     PRODUCTS.GROSS_MARGIN, 
     Format$([SALES].[TRANSDATE],'mmmm yyyy'), Year([SALES].[TRANSDATE])*12+DatePart('m',[SALES].[TRANSDATE])-1;

这实际上目前显示所有月份和年份的所有数据（我有2年所有产品的数据）。我只想要在一年（2011年5月到8月）的四个月中每个产品ID的总销售额。请帮助！

由于这是Access，因此SQL Fiddle只能是一个开始。

您需要正确“引用”日期表达式：

SELECT 
     PRODUCTS.PRODUCT_ID, 
     PRODUCTS.ITEM,      
     Sum(SALES.QUANTITY) AS [Sum Of QUANTITY]
FROM 
     PRODUCTS INNER JOIN 
     SALES ON PRODUCTS.[PRODUCT_ID] = SALES.[PRODUCT_ID]
WHERE 
    [SALES].[TRANSDATE] BETWEEN #2015-05-01# AND #2015-08-31#
GROUP BY 
     PRODUCTS.PRODUCT_ID, 
     PRODUCTS.ITEM

更正2015-07-23

我非常抱歉您错过了您的原始数据有2011年而不是2011年的日期。我特此发布更正后的SQL供您测试：

SELECT 
     PRODUCTS.PRODUCT_ID, 
     PRODUCTS.ITEM,      
     Sum(SALES.QUANTITY) AS [Sum Of QUANTITY]
FROM 
     PRODUCTS INNER JOIN 
     SALES ON PRODUCTS.[PRODUCT_ID] = SALES.[PRODUCT_ID]
WHERE 
    [SALES].[TRANSDATE] BETWEEN #2011-05-01# AND #2011-08-31#
GROUP BY 
     PRODUCTS.PRODUCT_ID, 
     PRODUCTS.ITEM

这将从Access数据库生成输出。但是，与SQL Fiddler一起使用时，它将有所不同：

SELECT 
     PRODUCTS.PRODUCT_ID, 
     PRODUCTS.ITEM,      
     Sum(SALES.QUANTITY) AS [Sum Of QUANTITY]
FROM 
     PRODUCTS INNER JOIN 
     SALES ON PRODUCTS.[PRODUCT_ID] = SALES.[PRODUCT_ID]
WHERE 
    [SALES].[TRANSDATE] BETWEEN '2011-05-01' AND '2011-08-31'
GROUP BY 
     PRODUCTS.PRODUCT_ID, 
     PRODUCTS.ITEM

很抱歉给您带来不便。
