【问题描述】：

我需要 mysql 订购方面的帮助，我有这个查询

SELECT
  videos_views.videos_views_id,
  videos_views.videos_views_date,
  SUM(IF(MONTH(videos_views.videos_views_date) = 2, videos_views.videos_views_total, 0)) AS total_view,
  videos.videos_id,
  videos.videos_title,
  videos.videos_description,
  videos.videos_author_list_id,
  author_list.author_list_name,
  author_list.author_list_id
FROM videos
  LEFT OUTER JOIN author_list
    ON videos.videos_author_list_id = author_list.author_list_id
  LEFT OUTER JOIN videos_views
    ON videos.videos_id = videos_views.videos_views_id
WHERE author_list.author_list_video_type = 1
AND videos.videos_id >= 51108
GROUP BY videos_views.videos_views_id,
         videos.videos_id
ORDER BY CASE WHEN MONTH(videos_views.videos_views_date) = 2 THEN SUM(videos_views.videos_views_total) END DESC, 
  CASE WHEN MONTH(videos_views.videos_views_date) <> 2 THEN videos.videos_id END DESC
LIMIT 11    

它会返回以下结果

如果我使用 DESC 或 ASC 使用第一顺序，则返回与上述相同的结果。

我使用二阶通过使用 ASC 返回结果如下：

我需要查询按以下顺序返回值

请帮帮我

【参考方案1】：

您的结果表明您想要：

order by total_views desc, videos_id desc

您可以在order by 中（安全地）引用列别名。
