MYSQL从select子查询中更新

Question

响应列中的数据为= blahblahblahTYPE=ERRORblahblah。然后我运行下面的查询来定位'ERROR'字符串。

SELECT substr(Response, instr(Response, 'ERROR'), 5) 
    FROM table 
    WHERE id = 721451 
    AND Status = 'false' 
    AND Response LIKE '%<status>Unknown</status>%' 
    AND date >= curdate(); 

以上查询返回：ERROR。

我基本上想更新ERROR到SUCCESS而不编辑其余的数据。

下面的查询会工作吗？有一个更好的方法吗？

UPDATE table 
    SET Response = 'SUCCESS' 
    WHERE (
    SELECT substr(Response, instr(Response, 'ERROR'), 5) 
     FROM table 
     WHERE id = 721451 
     AND Status = 'false' 
     AND Response LIKE '%<status>Unknown</status>%' 
     AND date >= curdate() 
); 

感谢您的帮助提前！

UPDATE table 
    SET Response = REPLACE(Response, 'ERROR', 'SUCCESS') 
    WHERE id = 721451 
    AND Status = 'false' 
    AND Response LIKE '%<status>Unknown</status>%' 
    AND date >= curdate();
