选择Mysql中的倒数第二行

Question

我一直在尝试获取mysql上数据的倒数第二行。 但是我的查询仅显示最后一行。

SELECT news.news_title, news.news_details, news.news_author, news_images.filename
FROM news JOIN news_images 
ON news.news_title = news_images.news_title 
ORDER BY news_id DESC LIMIT 1

Answer 1

使用OFFSET获取倒数第二个值，例如：

SELECT news.news_title, news.news_details, news.news_author, news_images.filename
FROM news JOIN news_images 
ON news.news_title = news_images.news_title 
ORDER BY news_id DESC
LIMIT 1 OFFSET 1;

LIMIT number_of_rows OFFSET start_from

如果要最后2行，请使用： LIMIT 2 。

编辑：您的问题非常不清楚，但尝试：

SELECT t.news_title, t.news_details, t.news_author, ni.filename
FROM (SELECT news_title, news_details, news_author
      FROM news
      ORDER BY news_id DESC
      LIMIT 1 OFFSET 1) AS t
JOIN news_images ni
  ON t.news_title = ni.news_title 

Answer 2

SELECT news.news_title, news.news_details, news.news_author, news_images.filename
FROM news JOIN news_images 
ON news.news_title = news_images.news_title 
ORDER BY news_id DESC
LIMIT 1 OFFSET 1;

您还应该参考选择数据库表中的第n个最高记录
