如何让新闻发表评论？

Question

我想获得包含评论的新闻，按评论总数排序

我尝试使用此SQL代码

SELECT COUNT( comment ) , N . * , C . * 
FROM news N, comment C
WHERE N.ID = C.ID_NEWS

但是问题是它只返回第一个包含所有评论的新闻

有什么解决办法吗？

Answer 1

我认为您想要这样的查询：

SELECT N.ID as comments_order, 
       count( C.comment ) as total_comments
  FROM news N INNER JOIN comment C
    ON (  N.ID = C.ID_NEWS )
 GROUP BY N.ID
 ORDER BY total_comments;
