Rule2 Object
未來的 Microsoft SQL Server 發行版本將不再提供此功能。請避免在新的開發工作中使用此功能，並計劃修改目前使用此功能的應用程式。
The Rule2 object exposes the attributes of a single Microsoft SQL Server data-integrity rule and extends the functionality of the Rule object.
Properties
備註
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.
