MySQL 从两个表与一个左连接

Question

我有两个表，它们的列几乎相同 - 视频列表和画廊列表。然后我想将其左连接到成员表，这样我就可以从成员 ID 中获取成员姓名。我最终得到的是按日期列排序的视频和画廊列表。我知道如何单独完成，但无法使其组合起来工作。以下是单独的查询:

//Video Query
SELECT videos.vid, videos.mid, videos.source, videos.category, videos.title, videos.description, videos.date_added, videos.status, members.name FROM videos LEFT JOIN members ON videos.mid=members.mid WHERE videos.status = 'published' ORDER BY date_added

//Gallery Query    
SELECT galleries.vid, galleries.mid, galleries.directory, galleries.category, galleries.title, galleries.description, galleries.date_added, galleries.status, members.name FROM videos LEFT JOIN members ON videos.mid=members.mid WHERE galleries.status = 'published' ORDER BY date_added 

但我无法让它与两个表的左连接一起使用。两个表都使用同一列进行左连接，并使用同一列进行排序。我可以执行一个查询还是必须查询两者并进行某种合并？

最终结果将类似于:

- Video A by John
- Gallery A by John
- Video B by John
- Video C by Mary

等等

谢谢!

Answer 1

您可以组合查询并编写类似的内容

SELECT 
  videos.vid,
  videos.mid,
  videos.source,
  videos.category,
  videos.title,
  videos.description,
  videos.date_added,
  videos.status,
  galleries.vid,
  galleries.mid,
  galleries.directory,
  galleries.category,
  galleries.title,
  galleries.description,
  galleries.date_added,
  galleries.status,
  members.name 
FROM
  videos 
  LEFT JOIN members 
    ON videos.mid = members.mid members.name 
FROM
  videos 
  LEFT JOIN members 
    ON videos.mid = members.mid 
    AND videos.status = 'published' 
  LEFT JOIN galleries 
    ON galleries.mid = members.mid 
AND galleries.status = 'published' 
ORDER BY galleries.date_added,videos.date_added 

我希望这会有所帮助。
