PHP MySQL连接几个连接表

Question

有2个查询：

select * from gallery_images JOIN photo_galleries ON photo_galleries.albumID=gallery_images.albumID


select * from multimedia_video JOIN video_content ON multimedia_video.id=video_content.id_href

此外，我在“photo_galleries”表上有“albumDateCreated”字段，在“multimedia_video”上有“DateCreated”字段。我想按这些字段对查询进行排序

加入我的2个“连接”的最佳技巧是什么？

Answer 1

就像你创造其他人一样：

SELECT * FROM gallery_images
    JOIN photo_galleries ON photo_galleries.albumID=gallery_images.albumID
    JOIN multimedia_video ON photo_galleries.albumDateCreated=multimedia_video.DateCreated
    JOIN video_content ON multimedia_video.id=video_content.id_href
