Column2 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 Column2 object represents the properties of a single column in a table in Microsoft SQL Server 2000 and later and extends the functionality of the Column object.
備註
The Column2 object extends the functionality of the Column object for use with features that were introduced in SQL Server 2000. It also inherits the properties and methods of the Column object. With the Column2 object, you can:
Retrieve information about column-level collation.
Set and retrieve attributes of image columns used in a full-text index.
Alter the data type of a column.
The methods and properties of the Column2 object may not be compatible with instances of SQL Server version 7.0 or earlier. For more information about using the Column2 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.
