如何爲獲取相關視頻編寫查詢？

Question

我的表是：

tb_videos

id, 
name 

tb_video_tags

id, 
video_id, 
tag 

我要選擇通過標籤視頻及其相關視頻。

Answer 1

SELECT v.name 
FROM tb_video_tags t, tb_video v 
WHERE v.id = t.video_id 

嘗試一下，有樂趣

Answer 2

你可以嘗試使用：

SELECT v.id, v.name, vr.id AS related_id, vr.name AS related_name 
    FROM tb_videos AS v 
LEFT JOIN tb_video_tags AS vt 
     ON vt.video_id = v.id 
LEFT JOIN tb_videos AS vr 
     ON vt.video_id = vr.id 
     AND v.id != vr.id
