CREATE USER

This statement creates a new user, specified with a password. In the MySQL privilege system, a user is the combination of a username and the host from which they are connecting from. Thus, it is possible to create a user 'newuser2'@'192.168.1.1' who is only able to connect from the IP address 192.168.1.1. It is also possible to have two users have the same user-portion, and different permissions as they login from different hosts.
