Замечания
To get Statistic object properties, users can be a member of the public fixed server role.
To set Statistic object properties, users must have ALTER permission on the parent table or view or be a member of the db_owner fixed database role.
To create or drop a statistics counter, users must have ALTER permission on the parent table or view or be a member of the db_owner fixed database role.
To update statistics, users must have ALTER permission on the parent table or view or be a member of the db_owner fixed database role.
Thread Safety
Все общие статические члены этого типа (Shared в Microsoft Visual Basic) можно использовать в многопоточных операциях. Потокобезопасная работа с членами экземпляров типа не гарантируется.
