这样一句SQL语句应该如何写？搞了很久没有做出来

------解决方案--------------------
select b.friend ,b.myfriend , a.icon, a.imageicon from 表B b inner join 表A a on b.myfriend=a.ident_name
------解决方案--------------------
select * from A where ident_name in (select myfriend from B where friend = '黄')
------解决方案--------------------
select b.friend,b.myfriend ,(select a.icon from 表A a where a.ident_name=b.myfriend) as icon, (select a.imageicon from 表A a where a.ident_name=b.myfriend) as imageicon from 表B b where b.friend='黄'

笨方法~~，不知道效率如何。
