尝试使用当前表中的某些列(Table1)并使用第二个表中的新列(Table2)组合在SQL(Table3)中创建新表时,出现以下错误:&#34 ;找不到任何一列" a"或用户定义的函数或聚合" a.sum",或名称不明确。"
代码如下:
select a. [Quarter]
,a. [Source Location]
,a. [Destination Location]
,a. sum([Total Volume]) as 'Total Volume'
,a. sum([Total Cost]) as 'Total Cost'
,b. [Source_City]
,b. [Source_State]
Into [2016].[dbo].[Table3]
FROM [2016].[dbo].[Table1] a
,[2016].[dbo].[Table2] b
Where a. [Source Location] = b. [Source_Location]
Group By a. [Quarter]
,a. [Source Location]
,a. [Destination Location]
,b. [Source_City]
,b. [Source_State]
错误参考[Quarter];但是,[Quarter]是表1中定义的列。另外,[Source_Location]是表2中定义的列。
任何人都可以协助解决此问题,并成功将这两个表合并为第三个表吗?
感谢您的帮助!

我不打算对格式的其他方面发表评论,但问题是您使用sum()
。你有:
a.sum([Total Volume]) as 'Total Volume',
a.sum([Total Cost]) as 'Total Cost'
正确的语法是:
sum(a.[Total Volume]) as [Total Volume],
sum(a.[Total Cost]) as [Total Cost]
