Rule2 Object
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 Rule2 object exposes the attributes of a single Microsoft SQL Server data-integrity rule and extends the functionality of the Rule object.
Замечания
The Rule2 object extends the functionality of the Rule object for use with features that were introduced in SQL Server 2000. It also inherits the properties and methods of the Rule object.
The IsDeleted property of the Rule2 object may not be compatible with instances of SQL Server version 7.0 or earlier. For more information about using the Rule2 object in an application that also runs with an instance of SQL Server 7.0, refer to the Remarks section of the IsDeleted property. For more information, see Programming Extended SQL-DMO Objects.
