Question

SQL查询相对较新。我可以成功地从一个简单的查询中获得结果，该查询显示客户编号和发票总额，将最高美元金额排序到最低。我还要显示客户名称。客户名称[Name]与客户编号一起位于另一个表中，但客户编号的列名称不同，即。 Table 1为[Bill-to Customer No_]，Table 2仅为[No_]。如何从Table 2获取与客户编号显示在同一行的信息？

Answer 1

SELECT 
       [bill-to Customer No_]
       ,customer_name 
FROM table1 AS a 
INNER JOIN table2 AS b on a.[bill-to Customer No_]=b.No_

Answer 2

select Bill-to, CustomerNo_ ,customer_name 
from Table1 a 
join Table2 b on a.CustomerNo_ = b.No_

Answer 3

SELECT [Bill-to Customer No_], [Invoice Amount] AS amt, [Name]
FROM Table1 t1 JOIN Table2 t2
ON t1.[Bill-to Customer No_] = t2.[No_]
ORDER BY amt DESC;

我还没有掌握你的专栏名称，但希望你明白这一点。

编辑 :(根据您的新查询）

SELECT [Sell-to Customer No_], [Name], SUM([Amount]) as "Total Dollars Spent" 
FROM [Table 1 - LIVE$Sales Invoice Line] a JOIN [Table 2 - LIVE$Customer] b
ON a.[Sell-to Customer No_] = b.[No_]
WHERE [Source Code] = 'RENTAL' and [Sell-to Customer No_] != 'GOLF' 
GROUP BY [Sell-to Customer No_], [Name]
ORDER BY SUM([Amount]) DESC;

您还需要将[Name]添加到GROUP BY子句中。请注意，SELECT除非GROUP BY正在处理[Amount]等群组功能处理的列，否则SUM()不能{{1}}列。{/ p>
