SystemDataType2 Object
未來的 Microsoft SQL Server 版本將移除這項功能。請避免在新的開發工作中使用這項功能，並規劃修改目前使用這項功能的應用程式。
The SystemDatatype2 object exposes the attributes of a Microsoft SQL Server base data type and extends the functionality of the SystemDatatype object.
備註
The SystemDatatype2 object extends the functionality of the SystemDatatype object for use with features that were introduced in SQL Server 2000. It also inherits the properties and methods of the SystemDatatype object. With the SystemDatatype2 object, you can:
- Set and retrieve column-level collation settings.
The Collation property of the SystemDatatype2 object may not be compatible with instances of SQL Server version 7.0 or earlier. For more information about using the SystemDatatype2 object in an application that also runs with an instance of SQL Server 7.0, refer to the Remarks section of the Collation property. For more information, see Programming Extended SQL-DMO Objects.
