Syntax
------

SHOW GRANTS [FOR user|role]

Description
-----------

The SHOW GRANTS statement lists privileges granted to a particular user or
role.

Users
-----

The statement lists the GRANT statement or statements that must be issued to
duplicate the privileges that are granted to a MariaDB user account. The
account is named using the same format as for the GRANT statement; for
example, 'jeffrey'@'localhost'. If you specify only the user name part of the
account name, a host name part of '%' is used. For additional information
about specifying account names, see GRANT.

SHOW GRANTS FOR 'root'@'localhost';
+---------------------------------------------------------------------+
| Grants for root@localhost                                           |
+---------------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' WITH GRANT OPTION |
+---------------------------------------------------------------------+

To list the privileges granted to the account that you are using to connect to
the server, you can use any of the following statements:

SHOW GRANTS;
SHOW GRANTS FOR CURRENT_USER;
SHOW GRANTS FOR CURRENT_USER();

If SHOW GRANTS FOR CURRENT_USER (or any of the equivalent syntaxes) is used in
DEFINER context (such as within a stored procedure that is defined with SQL
SECURITY DEFINER), the grants displayed are those of the definer and not the
invoker.

Note that the DELETE HISTORY privilege, introduced in MariaDB 10.3.4, was
displayed as DELETE VERSIONING ROWS when running SHOW GRANTS until MariaDB
10.3.15 (MDEV-17655).

Roles
-----

SHOW GRANTS can also be used to view the privileges granted to a role.

Example
-------

SHOW GRANTS FOR journalist;
+------------------------------------------+
| Grants for journalist                    |
+------------------------------------------+
| GRANT USAGE ON *.* TO 'journalist'       |
| GRANT DELETE ON `test`.* TO 'journalist' |
+------------------------------------------+

FOR PUBLIC
----------

MariaDB starting with 10.11
---------------------------
GRANT ... TO PUBLIC was introduced in MariaDB 10.11 to grant privileges to all
users. SHOW GRANTS FOR PUBLIC shows all these grants.

SHOW GRANTS FOR public;
+------------------------------------------------+
| Grants for PUBLIC                              |
+------------------------------------------------+
| GRANT ALL PRIVILEGES ON `dev_db`.* TO `PUBLIC` |
