本意向修改一个用户的密码，网上搜到的命令为如下 1 mysql> update user set password=password(“新密码”) where user=”用户名”; 执行后报错 ERROR 1054(42S22) Unknown column 'password' in ‘field list’ 错误的原因是 5.7版本下的mysql数据库下已经没有password这个字段了，password字段改成了authentication_string 所以请使用一下命令： 复制代码 >mysql -u root -p Enter password: ******** Welcome to the MySQL monitor.
