mysql - 按帖子计数对作者姓名排序

Question

我有两张 table 。

作者

Author_ID      Author_Name               
 -------------------------                      
1           name 1      
2           name 2    
3           name 3
 ---------------------------

发布

Post_ID      Author_ID
 -------------------------                      
1           1      
2           1    
3           2
4           3
5           3
6           3
 ---------------------------

我需要一个 mysql 查询来计算每个作者的帖子数量，然后将作者从大到小排序。

我目前的MySQL只显示名字:

select * from AUTHOR
where author_status = '1' ORDER BY author_name DESC

Answer 1

SELECT author.author_id, author.author_name, count(post.post_id) FROM AUTHOR, POST
    WHERE (author_status = '1')
    AND (author.author_id = post.author_id) 
GROUP BY author.author_id
ORDER BY author.author_name DESC;
