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 EVENT
privilege at global scope, replace the user specification ('USERNAME'@'HOSTNAME'
) in the following query to align to your requirements:
GRANT EVENT
ON *.*
TO 'USERNAME'@'HOSTNAME';
To grant the EVENT
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 EVENT
ON DATABASE_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 EVENT
privilege at global scope, replace the user specification ('USERNAME'@'HOSTNAME'
) in the following query to align to your requirements:
REVOKE EVENT
ON *.*
FROM 'USERNAME'@'HOSTNAME';
To revoke the EVENT
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 EVENT
ON DATABASE_NAME.*
FROM 'USERNAME'@'HOSTNAME';
SHOW Output
A user's privileges can be displayed using the SHOW GRANTS
statement.
If the EVENT
privilege is present, it will be shown as EVENT
in the output. For example:
SHOW GRANTS FOR 'app_user'@'192.0.2.%';
+-----------------------------------------------------+
| Grants for app_user@192.0.2.% |
+-----------------------------------------------------+
| GRANT EVENT ON `app_db`.* TO 'app_user'@'192.0.2.%' |
+-----------------------------------------------------+
Privilege Failure
The EVENT
privilege results in no failures since it makes no changes in operation.
