EXAMPLES

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

GRANT CREATE USER
  ON *.*
  TO 'USERNAME'@'HOSTNAME';

For general guidance on privileges, see "Privileges".

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

REVOKE CREATE USER
  ON *.*
  FROM 'USERNAME'@'HOSTNAME';

For general guidance on privileges, see "Privileges".

SHOW Output

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

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

SHOW GRANTS FOR 'app_user'@'192.0.2.%';
+----------------------------------------------------+
| Grants for app_user@192.0.2.%                      |
+----------------------------------------------------+
| GRANT CREATE USER ON *.* TO 'app_user'@'192.0.2.%' |
+----------------------------------------------------+

Privilege Failure

An error message is raised if an operation fails due to insufficient privileges. For example:

CREATE USER 'app_user'@'192.0.2.%';
ERROR 1045 (HY000): [11281] Permission denied: User 'USERNAME'@'HOSTNAME' is missing CREATE USER on *.*; transaction aborted
