如何在SQL Server 2008 R2中没有列名的列上使用SELECT？

Question

Here's my code: 这是我的代码：

SELECT DISTINCT Column 3
FROM [TestTable].[dbo].data

I get an error on "Column 3". 我在“第3列”上收到错误。 The error is Incorrect syntax near '3'. 错误是'3'附近的语法不正确。

My table has no column names so I don't know how to run my Select command on the third column. 我的表没有列名，所以我不知道如何在第三列上运行我的Select命令。

Answer 1

If the name of you third column is indeed 'Column 3', you need to run this query: 如果第三列的名称确实是“列3”，则需要运行此查询：

SELECT DISTINCT [Column 3]
FROM [TestTable].[dbo].data

Answer 2

AFAIK it's impossible to have a table with no column names AFAIK不可能有一个没有列名的表

Run 跑

USE TestTable
GO

select *
from INFORMATION_SCHEMA.COLUMNS
where TABLE_NAME='data'

to get the column names 获取列名称
