Group By ....使SQL Query无法正常执行

Question

我想看到日期范围内销售的总产品数量，即

 -------------------------
 |  PRODUCT   | QUANTITY |
 -------------------------
 |   A        |    120   |
 -------------------------
 |   B        |     75   |
 -------------------------

我在 MS Access 2003 ：

中有以下sql查询

SELECT Product, Sum(PurchaseQuantity) AS Quantity
FROM tblInvoice
GROUP BY Product
HAVING PurchaseDate BETWEEN #3/19/2013# and #3/22/2013#;

但这并没有执行。 MS Access给出了如下错误：

  

“您尝试执行不包含指定的查询   表达'PurchaseDate BETWEEN＃3/19/2013＃和＃3/22/2013＃'作为一部分   集合函数。“

到目前为止，我知道我需要在Group By子句中添加PurchaseDate。但是，如果不将PurchaseDate放在Group By子句中，有没有办法做到这一点？

提前谢谢。

您应该在“WHERE”子句中使用purchaseDate条件：

SELECT Product, Sum(PurchaseQuantity) AS Quantity 
FROM tblInvoice
WHERE PurchaseDate BETWEEN #3/19/2013# and #3/22/2013#
GROUP BY Product
