mysql> update user set password=password(“new password”) where user=”username”;
Error after execution ERROR 1054(42S22) Unknown column ‘password’ in ‘field list’

The reason for the error is that there is no password field in the mysql database under version 5.7, and the password field has been changed to authentication_string

>mysql -u root -p
