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

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

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

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

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

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

To revoke the UPDATE 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 UPDATE
  ON DATABASE_NAME.TABLE_NAME
  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 UPDATE privilege is present, it will be shown as UPDATE in the output. For example:

SHOW GRANTS FOR 'app_user'@'192.0.2.%';
+------------------------------------------------------+
| Grants for app_user@192.0.2.%                        |
+------------------------------------------------------+
| GRANT UPDATE 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:

UPDATE hq_sales.invoices
  SET payment_method = 'CASH'
  WHERE customer_id = 8;
ERROR 1045 (HY000): [11281] Permission denied: User 'USERNAME'@'HOSTNAME' is missing UPDATE on `hq_sales`.`invoices`; transaction aborted
