매개 변수

• lOutputID
  The ID of the IDTSOutput90 object.

• lOutputColumnID
  The ID of the IDTSOutputColumn90 object.

• lExternalMetadataColumnID
  The ID of the IDTSExternalMetadataColumn90 object that is linked to the output column.

• bMatch
  Indicates whether the output column and external metadata columns match.

반환 값

The IDTSExternalMetadataColumn90 that is mapped to the output column.

주의

This method is called to map an output column to a column in the ExternalMetadataColumnCollection of the output. When you are developing a custom data flow component, you override this method, to ensure that the external columns and the output column match, and to indicate that you want to allow the mapping to occur. For more information about working with external metadata columns, see Implementing External Metadata.
