LinkedServer2 Object
后续版本的 Microsoft SQL Server 将删除该功能。 请避免在新的开发工作中使用该功能，并着手修改当前还在使用该功能的应用程序。
The LinkedServer2 object exposes the properties of an OLE DB data source, allows directed Transact-SQL queries against defined data sources, and extends the functionality of the LinkedServer object.
注释
The LinkedServer2 object extends the functionality of the LinkedServer object for use with features that were introduced in Microsoft SQL Server 2000. It also inherits the properties and methods of the LinkedServer object.
The methods and properties of the LinkedServer2 object may not be compatible with instances of SQL Server version 7.0 or earlier. For more information about using the LinkedServer2 object in an application that also runs with an instance of SQL Server 7.0, refer to the Remarks section for specific methods and properties. For more information, see Programming Extended SQL-DMO Objects.
