MySQL加入查詢 - 不是唯一表/別名

Question

這個問題有什麼問題？我收到錯誤＃1066 - 不唯一表/別名：'v'

SELECT v.newsid AS identifier, j.createdate AS DATE, j.newstext AS TEXT, j.uuid AS user, j.flags AS fcount, j.votes AS vcount, j.authornick AS nick 
FROM votes v 
INNER JOIN news v ON j.newsid = v.newsid GROUP BY v.newsid ORDER BY COUNT(v.newsid) 
LIMIT 20 

Answer 1

您不能使用多次相同的表別名。您被關聯v與votes和表news。

更改您的查詢和別名引用類似

SELECT ..... 
FROM votes v 
INNER JOIN news n ON .... 
       ^^^ <=== Change this to something else 

Answer 2

我覺得這個消息表的別名應該是「J」。您在聯合聲明中使用了「j.newsid = v.newsid」
