參數

• lInputID
  The ID of the IDTSInput90.

• pIDTSVirtualInputObject
  The IDTSVirtualInput90 object that contains the virtual input column and that is used to map the IDTSInputColumn90 object.

• lLineageID
  The LineageID property of the IDTSVirtualInputColumn90 object.

• eUsageType
  A value from the DTSUsageType enumeration that is assigned to the IDTSInputColumn90.

傳回值

The IDTSInputColumn90 object whose UsageType is set.

備註

SetUsageType is called when a column from the IDTSVirtualInputColumnCollection90 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 IDTSVirtualInputColumn90 specified by the lLineageID parameter. If usageType is UT_IGNORED and the column exists in the collection, the column is removed and null is returned.
