注释

To get Trigger object properties, users can be a member of the public fixed server role.

To set Trigger object properties, users must have ALTER permission on the parent table or view.

To create or drop a trigger, users must have ALTER permission on the parent table or view.

To grant, deny, or revoke permission on the trigger to other users, users must have CONTROL permission on the trigger.
