UserDefinedDataType2 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 UserDefinedDatatype2 object exposes the attributes of a single Microsoft SQL Server user-defined data type and extends the functionality of the UserDefinedDatatype object.

備註
The UserDefinedDatatype2 object extends the functionality of the UserDefinedDatatype object for use with features that were introduced in SQL Server 2000. It also inherits the properties and methods of the UserDefinedDatatype object. With the UserDefinedDatatype2 object, you can:

The properties of the UserDefinedDatatype2 object may not be compatible with instances of SQL Server version 7.0 or earlier. For information about using the UserDefinedDatatype2 object in an application that also runs with an instance of SQL Server 7.0, refer to the Remarks section for specific properties.
