选择语句上的SQL内部联接 [英] SQL Inner join on select statements

问题描述

我正在尝试对这样的select语句进行内部联接:

I am trying to make an inner join on a select statement like this:

select *
from (select* from bars  where rownum <= 10 )as tab1
inner join (select * from bars  where rownum <= 10 )as tab2
on tab1.close=tab2.close

，出现以下错误: ORA-00933 SQL命令未正确结束 任何帮助将不胜感激，谢谢！

and I get the following error: ORA-00933 SQL command not properly ended Any help would be appreciated, thank you!

推荐答案

只需从查询中删除as:

select *
from (select* from bars  where rownum <= 10 ) tab1
inner join (select * from bars  where rownum <= 10 ) tab2
on tab1.close=tab2.close
