MYSQL加入帮助。 根据单独评论表中的评论数量获得结果？

Question

Beginner here! I am trying to write a query that will select the 3 most commented on results from a "results" table the comments are stored in a seperate "comments" table.

results
 - id  
 - title    
 - body   
 - etc
 - etc

comments
 - id  
 - result_id
 - user_id
 - timestamp
 - comment

So I need to select all from results and order by the amount of matches between results.id and comments.result_id but I don't really know where to start!

Thanks a lot for the help, it's much appreciated!

Answer 1

Not tested but you can do something like that

SELECT  r.id  ,r.title, r.body
FROM results r INNER JOIN (SELECT result_id, count(id) cnt FROM comments GROUP BY result_id) c
ON r.id = c.result_id
ORDER by c.cnt DESC
