MySQL的更新值在列中當有另外兩個特定的文本

Question

我有phpmyadmin頁面，我必須改變我的數據庫中的很多行。我有表'lime_answers'，並在裏面我有答案和語言列。我想要做的就是更新所有的答案，比如說「littlepony」到「bigpony」，但只有當語言列在該行中有「en」時纔可以。所以像

SELECT * FROM 'lime_answers' WHERE ('answer' = 'littlepony' AND 'language' = 'en') 
then SET 'answer' = 'bigpony' 

這可能嗎？

Answer 1

嘗試使用

update lime_answers set answer = 'bigpony' where answer = 'littlepony' AND language = 'en' 

Answer 2

Try this 


update 'lime_answers' set 'answer' = 'bigpony' 
    where ('answer' = 'littlepony' AND 'language' = 'en') 

Answer 3

UPDATE lime_answers SET `answer` = 'bigpony' WHERE (`answer` = 'littlepony' AND `language` = 'en') 

使用此
