mysql.global_priv Table

The mysql.global_priv table contains information about users that have permission to access the MariaDB server, and their global privileges. It was introduced in MariaDB 10.4.1 to replace the mysql.user table in earlier versions.

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:

FieldTypeNullKeyDefaultDescription
Hostchar(60)NOPRIHost (together with User makes up the unique identifier for this account).
Userchar(80)NOPRIUser (together with Host makes up the unique identifier for this account).
PrivlongtextNOGlobal privileges, granted to the account and other account properties

From MariaDB 10.5.2, in order to help the server understand which version a privilege record was written by, the priv field contains a new JSON field, version_id (MDEV-21704).
