Question

我已经通过ODBC将Access数据库文件连接到MS SQL 05.我有一个包含5个数据字段的表：

示例：

Date          Receipt No.   Customer No.   Item No.     Net Amount
----          -----------   ------------   --------     ----------
09/01/2016    M00001        111111         123          100
09/01/2016    M00001        111111         XXX          0
09/01/2016    M00002        222222         123          100
09/01/2016    M00002        222222         XXX          0

如果商品编号（相同的收据编号）有一个名为“XXX”的文本，我想得到的数据总和总数，并计算10％的净金额总和。

对于上面的示例，它将获得10美元的收据结果。 M00001。

Answer 1

如果您想要每个收据的净金额总和，其项目编号为＆＃39; XXX＆＃39;，您需要获取那些其商品名为＆no;＆＃39; XXX＆＃39; 因此，以下查询将给出此结果 SELECT ReceiptNo FROM TableName WHERE ItemNo =＆＃34; XXX＆＃34;

现在，要找到总金额的10％，您有2个选项

1）使用innerjoin

 SELECT  B.ReceiptNo, SUM(A.NetAmount)/10 FROM TableName A  INNER JOIN
 (SELECT  ReceiptNo FROM TableName WHERE ItemNo = "XXX")B 
 ON A.ReceiptNo = B.ReceiptNo GROUP BY B.ReceiptNo

2）使用In Clause

 SELECT  ReceiptNo, SUM(A.NetAmount)/10 FROM TableName WHERE ReceiptNo
 IN (SELECT  ReceiptNo FROM TableName WHERE ItemNo = "XXX")

您能告诉我们在哪里放置此查询吗？它是在我查询的SQL视图中吗？ - 帕特里克，我手头有这个问题......

SELECT [dbo_xxx$Trans_ Sales Entry].Date, [dbo_xxx$Trans_ Sales Entry].[Receipt No_], [dbo_xxx$Trans_ Sales Entry].[Customer No_], [dbo_xxx$Trans_ Sales Entry].[Net Amount], [dbo_xxx$Trans_ Sales Entry].[Item No_]

FROM [dbo_xxx$Trans_ Sales Entry]

GROUP BY [dbo_xxx$Trans_ Sales Entry].Date, [dbo_xxx$Trans_ Sales Entry].[Receipt No_], [dbo_xxx$Trans_ Sales Entry].[Customer No_], [dbo_xxx$Trans_ Sales Entry].[Net Amount], [dbo_xxx$Trans_ Sales Entry].[Item No_]

HAVING ((([dbo_xxx$Trans_ Sales Entry].Date)>#7/31/2016#));
