根据喜欢和不喜欢对评论进行排序

Question

请帮助，请更正查询，我需要根据喜欢和不喜欢的方式对评论进行排序（即喜欢和解雇的总和：cnt_total = cnt_like + cnt_dislike，上面显示了更多cnt_total），以及cnt_total是平等的 - 按日期排序。 cnt_total只是一个例子，它不在表格中。

包含列的表注释：id_comment，id_user，id_news，comment，id_parent，date_time，cnt_like，cnt_dislike，is_active。

SELECT u.login, c.* 
FROM comments c
LEFT JOIN users u ON u.id = c.id_user
WHERE id_news = '{$id_news}' AND c.is_active = 1 
ORDER BY id_parent, date_time DESC

Answer 1

试试这个：

SELECT u.login, c.*, c.cnt_like + c.cnt_dislike AS cnt_total 
FROM comments c
LEFT JOIN users u ON u.id = c.id_user
WHERE id_news = '{$id_news}' AND c.is_active = 1 
ORDER BY cnt_total DESC, date_time DESC
