EnumLastStatisticsUpdates Method

В будущей версии Microsoft SQL Server эта возможность будет удалена. Избегайте использования этой возможности в новых разработках и запланируйте изменение существующих приложений, в которых она применяется.

The EnumLastStatisticsUpdates method returns a QueryResults object that enumerates the query optimizing statistics maintained on a table.
