Mysql 需要在两个表上编写查询

我有两张桌子

Member (member_id,...)
friend-requests(member_id, friend_id)

我需要从member_id为19且不在friend_id列中的member表中获取所有记录

Select m.* from Member as m 
where member_id=19 and 
member_id not in (select friend_id from friend_requests where member_id=19)

select * from member join friend-requests
on member.member_id=friend_requests.member_id
where
member.member_id=19
and
not exists (select f.member_id from friend-requests f where f.mmeber_id = member.member_id)
