MySQL has an advanced but non-standard security authorization system. mastering its authorization mechanism is the first step to start operating MySQL databases. for a person familiar with basic SQL operations, it is also a hard part of all MySQL

The following example shows how to use a MySQL client to install a new user. These examples assume that the permission has been installed by default. This means that, in order to change, you must be on the same machine that MySQL is running, you
