附註：
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 DTP_VARIANT that contains the data in the column.

備註

This method returns a pointer to the data stored in the column specified by the hCol parameter. This pointer is used to directly modify the data in the column specified by hCol instead of calling the GetData method, modifying the data, and then calling SetData.
