매개 변수

• lInputID
  유형: System.Int32
  The ID of the IDTSInput100.

• pIDTSVirtualInputObject
  유형: 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
  유형: System.Int32
  The LineageID property of the IDTSVirtualInputColumn100 object.

• eUsageType
  유형: Microsoft.SqlServer.Dts.Pipeline.Wrapper.DTSUsageType
  A value from the DTSUsageType enumeration that is assigned to the IDTSInputColumn100.

반환 값

유형: Microsoft.SqlServer.Dts.Pipeline.Wrapper.IDTSInputColumn100
The IDTSInputColumn100 object whose UsageType is set.

주의

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 nullnull 참조(Visual Basic에서는 Nothing) is returned.
