Question

尝试按照this解决方案中给出的步骤更改mysql密码时，出现以下错误-

mysql> UPDATE mysql.user SET authentication_string = PASSWORD('letsrock') WHERE User = 'root' AND Host = 'localhost';
ERROR 1064 (42000): 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 '('letsrock') WHERE User = 'root' AND Host = 'localhost'' at line 1

在mysql中是否有用于update命令的新语法？我正在使用8.0.12版本。

Answer 1

“用户”和“主机”都是保留字，如果不将其括在反引号中，则不能用作标识符。像这样：

UPDATE mysql.user 
SET authentication_string = PASSWORD('letsrock') 
WHERE `User` = 'root' AND `Host` = 'localhost';

请参阅：https://dev.mysql.com/doc/refman/8.0/en/keywords.html
