sql - 当公共列名称不同但两个表中的信息相同时如何连接两个sql表

Question

SQL 查询相对较新。我可以从一个简单的查询中成功获得结果，该查询显示了客户编号和开票的总美元金额，从最高美元金额到最低金额。我还想显示客户名称。客户名称[Name]与客户编号一起在另一个表中，但客户编号的列名称不同，即。Table 1是[Bill-to Customer No_]和Table 2只是[No_]。如何获取信息Table 2以与客户编号显示在同一行？

Answer 1

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;

我还没有掌握你的列名，但希望你明白。

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;

您还需要添加[Name]到GROUP BY子句中。请记住SELECT，GROUP BY除非它正在由一个组函数[Amount]处理，例如正在由SUM().

Answer 2

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 3

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