我有以下三个表(仅出于表示原因显示必填字段)。
表'product_master'
ID ProductName
1 Jens
2 T-shirt
3 Shirt
4 Cap
表'账单'
ID Invoiceno Date
1 INV001 19/9/2013
2 INV002 20/9/2013
3 INV003 20/9/2013
表'billDetails'
ID Invoiceno Productid Qyt
1 INV001 1 2
2 INV001 2 3
3 INV001 4 1
4 INV002 2 1
5 INV002 3 2
6 INV003 1 3
7 INV003 4 2
我想要的输出
SalesReport(任意两个日期之间的每日)
ProductName TotalSales Date
Jens 2 19/9/2013
T-shirt 4 19/9/2013
Shirt 2 19/9/2013
Cap 1 19/9/2013
Jens 3 20/9/2013
T-shirt 0 20/9/2013
Shirt 0 20/9/2013
Cap 2 20/9/2013
此查询不起作用:
SELECT
[PM.product_master], [SUM(IM.Qyt)], [BM.Date] FROM
[product_master] AS PM
INNER JOIN
[billDetails] AS IM
ON
[PM.sno] = [IM.prod_sno]
INNER JOIN
[bill] AS BM
ON
[IM.Invoiceno] = [BM.Invoiceno]
答案 0 :(得分:3)
现在我想要这样的输出SalesReport(任意两个之间的每日 日期)
为了计算每天的总销售额,您必须按日期group
数据。要指定期间,您必须使用having
子句。
SELECT product_master.ProductName, Sum(billDetails.Qty) AS SumOfQty, bill.Dated
FROM bill
INNER JOIN (
product_master INNER JOIN billDetails ON product_master.ID = billDetails.ProductId
) ON bill.InvoiceNo = billDetails.InvoiceNo
GROUP BY product_master.ProductName, bill.Dated
HAVING bill.Dated Between #9/19/2013# And #9/20/2013#
ORDER BY bill.Dated, product_master.ProductName
答案 1 :(得分:1)
尝试此查询
select product_master.ProductName
,SUM(billDetails.Qyt) as TotalSales
,bill.Date
from billDetails
inner join bill on billDetails.Invoiceno = bill.Invoiceno
inner join product_master on product_master.Id = billDetails.Productid
