    lExternalMetadataColumnID : int
) : IDTSExternalMetadataColumn100

參數

• lInputID
  型別：System. . :: . .Int32
  The ID of the IDTSInput100 object.

• lInputColumnID
  型別：System. . :: . .Int32
  The ID of the IDTSInputColumn100 object.

• lExternalMetadataColumnID
  型別：System. . :: . .Int32
  The ID of the IDTSExternalMetadataColumn100 object.

傳回值

型別：Microsoft.SqlServer.Dts.Pipeline.Wrapper. . :: . .IDTSExternalMetadataColumn100
The IDTSExternalMetadataColumn100 object that the input column is mapped to.

實作

IDTSDesigntimeComponent100. . :: . .MapInputColumn(Int32, Int32, Int32)

備註

Call this method to map an IDTSInputColumn100 of a component to a column in the ExternalMetadataColumnCollection of the input.
