Sql server ms sql错误：关键字'；在'；

关键字“on”附近的语法不正确。

您需要为子查询添加别名

select * 
from other table inner join
(
select Count(*),
F1,F2,F3
from Table
group by F1,F2,F3
) on F1 = OtherF

---

您的子选择需要使用别名：

select * from other table inner join ( select Count(*), F1,F2,F3 from Table group by F1,F2,F3 ) s on s.F1 = OtherF

select * 
from other AS o 
inner join ( select Count(*), F1,F2,F3 
             from Table 
             group by F1,F2,F3 ) AS x on F1 = o.OtherF
