Destination Custom Properties
Изменения: 14 апреля 2006 г.
The data flow objects in the Microsoft SQL Server 2005 Integration Services object models have common properties and custom properties at the level of the component, inputs and outputs, and input columns and output columns. The custom properties are available only at run time, and are not documented in the Integration Services Managed Programming Reference Documentation.
This topic lists and describes the custom properties of data flow destinations.
- Data Mining Model Training Destination
- DataReader Destination
- Dimension Processing Destination
- Flat File Destination
- OLE DB Destination
- Partition Processing Destination
- Raw File Destination
- Recordset Destination
- SQL Server Compact Edition Destination
