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

GRANT ALTER ROUTINE
  ON *.*
  TO 'USERNAME'@'HOSTNAME';

To grant the ALTER ROUTINE privilege at database scope, replace the user specification ('USERNAME'@'HOSTNAME') and database name (DATABASE_NAME) in the following query to align to your requirements:

GRANT ALTER ROUTINE
  ON DATABASE_NAME.*
  TO 'USERNAME'@'HOSTNAME';

To grant the ALTER ROUTINE privilege at routine scope, replace the user specification ('USERNAME'@'HOSTNAME'), database name (DATABASE_NAME), and routine name (ROUTINE_NAME) in the following query to align to your requirements:

GRANT ALTER ROUTINE
  ON DATABASE_NAME.ROUTINE_NAME
  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 ALTER ROUTINE privilege at global scope, replace the user specification ('USERNAME'@'HOSTNAME') in the following query to align to your requirements:

REVOKE ALTER ROUTINE
  ON *.*
  FROM 'USERNAME'@'HOSTNAME';

To revoke the ALTER ROUTINE privilege at database scope, replace the user specification ('USERNAME'@'HOSTNAME') and database name (DATABASE_NAME) in the following query to align to your requirements:

REVOKE ALTER ROUTINE
  ON DATABASE_NAME.*
  FROM 'USERNAME'@'HOSTNAME';

To revoke the ALTER ROUTINE privilege at routine scope, replace the user specification ('USERNAME'@'HOSTNAME'), database name (DATABASE_NAME), and routine name (ROUTINE_NAME) in the following query to align to your requirements:

REVOKE ALTER ROUTINE
  ON DATABASE_NAME.ROUTINE_NAME
  FROM 'USERNAME'@'HOSTNAME';

SHOW Output

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

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

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

+-------------------------------------------------------------+
| Grants for app_user@192.0.2.%                               |
+-------------------------------------------------------------+
| GRANT ALTER ROUTINE ON `app_db`.* TO 'app_user'@'192.0.2.%' |
+-------------------------------------------------------------+

Privilege Failure

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

CREATE DATABASE db1;

DELIMITER //

CREATE PROCEDURE db1.test_proc ()
  BEGIN
     SELECT 1;
  END//

DELIMITER ;

DROP PROCEDURE db1.test_proc;

ERROR 1045 (HY000): [11281] Permission denied: User 'USERNAME'@'HOSTNAME' is missing ALTER ROUTINE on `db1`.*; transaction aborted
