三表更新，並加入導致錯誤1064

Question

我想執行以下代碼：

UPDATE 
    CustomerShowing 
SET 
    CustomerShowing.rate = 5 
FROM 
    CustomerShowing 
INNER JOIN 
    Showing 
ON 
    CustomerShowing.showid = Showing.showid 
INNER JOIN 
    Movie 
ON 
    Showing.movieid = Movie.movieid 
WHERE 
    Movie.name='Batman'; 

但是我收到以下錯誤：

ERROR 1064 (42000) at line 86: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FROM CustomerShowing INNER JOIN Showing ON CustomerShowing.ShowingID = Showing' at line 3

我怎麼能解決這個問題？我正在使用MySQL版本5.5.53。

Answer 1

MySQL使用與SQL-Server不同的語法。

UPDATE CustomerShowing 
INNER JOIN Showing ON CustomerShowing.showid = Showing.showid 
INNER JOIN Movie ON Showing.movieid = Movie.movieid 
SET CustomerShowing.rate = 5 
WHERE Movie.name='Batman';
