SQL Server - 附近的语法不正确)

Question

你能看一下这段代码吗？我收到此错误,我不确定是什么导致它:

')'附近的语法不正确.

select * 
from
    (select distinct 
         sar90.code, sar90.state, sar90.county, 
         sabet.code, sabet.state, sabet.county 
     from
         [dbo].[sarshomari_90] as sar90, 
         [dbo].[Fixed] as sabet 
     where 
         sar90.county = sabet.county 
         and sar90.state = sabet.state 
         and sar90.state = N'kerman')

Answer 1

您需要为子查询添加别名.但是,您不需要使用子查询.你可以SELECT DISTINCT直接使用.另外,请避免使用旧式JOIN语法并使用显式JOIN声明.

但是,如果要使用子查询,则列必须具有唯一的名称.通过添加唯一别名来完成此操作.

select *
from(
    select distinct
        sar90.code as code1, 
        sar90.state as state1,
        sar90.county as country1,
        sabet.code as code2,
        sabet.state as state2,
        sabet.county as country2
    from [dbo].[sarshomari_90] as sar90
    inner join [dbo].[Fixed] as sabet 
        on sar90.county = sabet.county 
        and sar90.state = sabet.state 
    where
        sar90.state = N'kerman'
