Question

大家好，基本上我试图做的就是这个......

我写了这个查询..

SELECT * from comments where author = (select min(author ) from comments )

这是结果..

但我不确定此查询是否正确

谢谢！

Answer 1

为什么你不试这个：

SELECT *,COUNT(*) nr_coments
FROM comments 
GROUP BY author 
ORDER BY nr_coments DESC
LIMIT 1

Answer 2

试试这个：

select username, first name, last name, count( username) from comments 
group by username, first name, last name
order by count(username)

这可能会有所帮助......

Answer 3

试试这个，

SELECT
   Author,
   count(Comment)
FROM 
   table_name 
GROUP BY author 
ORDER BY 
   count(comment) 
DESC LIMIT 1;
