mysql – ERROR 1064(42000)：您的SQL语法有错误;想要以root用户身份配置密码

以下是输入

    mysql-> use mysql
    Database changed
    mysql-> UPDATE user
         -> SET Password=PASSWORD<'elephant7'>
         -> WHERE user='root';

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 ‘WHERE user=’root” at line 3

SET PASSWORD FOR 'root' = PASSWORD('elephant7');

或者,在最新版本中：

SET PASSWORD FOR root = 'elephant7' 

您还可以使用：

UPDATE user SET password=password('elephant7') WHERE user='root';

但在Mysql 5.7中,字段密码不再存在,你必须使用：

UPDATE user SET authentication_string=password('elephant7') WHERE user='root';

问候
