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

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

To grant the INDEX 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 INDEX
  ON DATABASE_NAME.*
  TO 'USERNAME'@'HOSTNAME';

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

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

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

To revoke the INDEX 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 INDEX
  ON DATABASE_NAME.*
  FROM 'USERNAME'@'HOSTNAME';

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

REVOKE INDEX
  ON DATABASE_NAME.TABLE_NAME
  FROM 'USERNAME'@'HOSTNAME';

SHOW Output

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

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

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

+-----------------------------------------------------+
| Grants for app_user@192.0.2.%                       |
+-----------------------------------------------------+
| GRANT INDEX 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:

ALTER TABLE hq_sales.invoices
  ADD INDEX invoice_date_idx (invoice_date);

ERROR 1045 (HY000): [11281] Permission denied: User 'USERNAME'@'HOSTNAME' is missing INDEX on `hq_sales`.`invoices`; transaction aborted
