MySQL（最热门）排序2个不同的参数（最喜欢的时间更短）

Question

我一直在努力弄清楚如何"Hottest Posts"选择帖子，most upvoted in shortest time选择帖子。

我有2个数据库表：

fun_posts：

fun_post_upvotes：

我的最新代码仍然不起作用：

$stmt = $this->conn->prepare("SELECT * FROM fun_posts, (SELECT image_id, COUNT(*) FROM fun_post_upvotes GROUP BY image_id)
            WHERE id = image_id ORDER BY id DESC, upvotes DESC");

Answer 1

尝试使用此查询：

$stmt = $this->conn->prepare=("SELECT * , (SELECT COUNT(*) 
                                           FROM fun_post_upvotes 
                                           WHERE image_id=fun_posts.id
                                           GROUP BY image_id)
                               FROM fun_posts
                               ORDER BY fun_posts,id DESC, fun_posts.upvotes DESC");
