FILE Privilege

GRANT

The following examples demonstrate grant of a single privilege. A single GRANT statement can grant multiple privileges at the same scope by providing a comma-separated list of the privileges.

To grant the FILE privilege at global scope, replace the user specification ('USERNAME'@'HOSTNAME') in the following query to align to your requirements:

GRANT FILE
  ON *.*
  TO 'USERNAME'@'HOSTNAME';

REVOKE

The following examples demonstrate revoke of a single previously-granted privilege. A single REVOKE statement can revoke multiple privileges at the same scope by providing a comma-separated list of the privileges.

To revoke the FILE privilege at global scope, replace the user specification ('USERNAME'@'HOSTNAME') in the following query to align to your requirements:

REVOKE FILE
  ON *.*
  FROM 'USERNAME'@'HOSTNAME';

SHOW Output

A user's privileges can be displayed using the SHOW GRANTS statement.

If the FILE privilege is present, it will be shown as FILE in the output. For example:

SHOW GRANTS FOR 'app_user'@'192.0.2.%';

+---------------------------------------------+
| Grants for app_user@192.0.2.%               |
+---------------------------------------------+
| GRANT FILE ON *.* TO 'app_user'@'192.0.2.%' |
+---------------------------------------------+

Privilege Failure

The FILE privilege results in no failures since it makes no changes in operation.
