选择Mysql中的第二行

Question

我一直试图获取关于mysql的第二行数据。但我的查询只显示最后一行。

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，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

如果您想要最后两行，请使用：LIMIT 2。

修改 你的问题很不清楚，但试试：

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;
