mysql> update mysql.user set Password = PASSWORD(‘mysql’) where user =’root’;
ERROR 1054 (42S22): Unknown column ‘Password’ in ‘field list’

WHY ??????
This was working all good in other instances of MySQL where i had earlier versions installed, why not this one – Puzzled, Perplexed!
Let me check version information of this instance.

mysql> show variables like "%version%";
+-------------------------+------------------------------+
| Variable_name | Value |
+-------------------------+------------------------------+
| innodb_version | 5.7.20 |
| protocol_version | 10 |
| slave_type_conversions | |
| tls_version | TLSv1,TLSv1.1 |
| version | 5.7.20 |
| version_comment | MySQL Community Server (GPL) |
| version_compile_machine | x86_64 |
| version_compile_os | Linux |
+-------------------------+------------------------------+
8 rows in set (0.01 sec)

Well, starting from MySQL version 5.7 the PASSWORD column from mysql.user table has been removed and now replaced with ‘authentication_string’.
So the all new syntax for this password reset would be like this …

mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql>

mysql> update user set authentication_string=password(‘mysql’) where user=’root’;
Query OK, 2 rows affected, 1 warning (0.00 sec)
Rows matched: 3 Changed: 2 Warnings: 1

Hope That Helps
