sql - 从sql server中的子查询创建临时表导致错误

Question

我有这样的东西

 if object_id('tempdb.#TempHourlyTable') is not null
drop table #TempHourlyTable

 select * into #TempHourlyTable
 from (
         select top 10 * from customers
      )

我收到这样的错误:

Incorrect syntax near ')'.

我第一次尝试使用临时表。那么这里的错误是什么？

编辑:
如果存在临时表，则删除并重新创建。获取错误

Msg 2714, Level 16, State 6, Line 55
There is already an object named '#TempHourlyTable' in the database.

您需要为派生表(子查询)设置别名，例如:

select * into #TEmpTable
 from (
         select top 10 * from customers
      ) as [SomeAlias]

您还可以:

select top 10 * 
into #temp
from customers
