Database Event Grants
The valid database event permissions are summarized below:
Raise
Allows grantees to raise the database event (using the RAISE DBEVENT statement).
Register
Allows grantees to register to receive the database event (using the REGISTER DBEVENT statement).
These are enabling permissions--by default, execution is prohibited unless the permission is specifically granted. Database event permissions are not enforced for the owner of the event.
