Parametri
- lInputID
Tipo: System.Int32
The ID of the IDTSInput100.
- pIDTSVirtualInputObject
Tipo: Microsoft.SqlServer.Dts.Pipeline.Wrapper.IDTSVirtualInput100
The IDTSVirtualInput100 object that contains the virtual input column and that is used to map the IDTSInputColumn100 object.
- lLineageID
Tipo: System.Int32
The LineageID property of the IDTSVirtualInputColumn100 object.
- eUsageType
Tipo: Microsoft.SqlServer.Dts.Pipeline.Wrapper.DTSUsageType
A value from the DTSUsageType enumeration that is assigned to the IDTSInputColumn100.
Valore restituito
Tipo: Microsoft.SqlServer.Dts.Pipeline.Wrapper.IDTSInputColumn100
The IDTSInputColumn100 object whose UsageType is set.
Osservazioni
SetUsageType is called when a column from the IDTSVirtualInputColumnCollection100 is selected for a component. If the usageType is UT_READONLY or UT_READWRITE, a new input column is created for the component that reflects the IDTSVirtualInputColumn100 specified by the lLineageID parameter. If usageType is UT_IGNORED and the column exists in the collection, the column is removed and nullriferimento Null (Nothing in Visual Basic). is returned.
