mysql.global_priv Table

MariaDB starting with 10.4.1

The mysql.global_priv table was introduced in MariaDB 10.4.1 to replace the mysql.user table.

The mysql.global_priv table contains information about users that have permission to access the MariaDB server, and their global privileges.

Note that the MariaDB privileges occur at many levels. A user may not be granted create privilege at the user level, but may still have create permission on certain tables or databases, for example. See privileges for a more complete view of the MariaDB privilege system.

The mysql.global_priv table contains the following fields:

Field Type Null Key Default Description
Host char(60) NO PRI Host (together with User makes up the unique identifier for this account).
User char(80) NO PRI User (together with Host makes up the unique identifier for this account).
Priv longtext NO Global privileges, granted to the account and other account properties

Examples

select * from mysql.global_priv;
