如何使用外键从另一个表的顺序中获取记录

Question

I have two tables in my SQL, 'post' and 'business' The columns in the post are:

• Post_ID
• Content
• Img
• Business_ID

The columns in business are

• Business_ID
• Business name
• Business rating

What I want is I want the posts which are posted by businesses with high business rating come first before others, please is there a way to fetch the posts with order of business rating???

Answer 1

To order results of posts with associated business rating you need a join query

select p.*
from posts as p
join business as b on b.business_id = p.business_id
order by b.business_rating desc

Answer 2

order by查询排列评级使用order by

select * from posts,business order by business_rating where posts.business_ID=business.business_ID;
