/** @attribute DispIdAttribute(34) */ 
IDTSExternalMetadataColumn90 MapOutputColumn (
    /** @attribute InAttribute() */ int lOutputID, 
    /** @attribute InAttribute() */ int lOutputColumnID, 
    /** @attribute InAttribute() */ int lExternalMetadataColumnID,

DispIdAttribute(34) 
function MapOutputColumn (
    lOutputID : int, 
    lOutputColumnID : int, 
    lExternalMetadataColumnID : int, 
    bMatch : boolean
) : IDTSExternalMetadataColumn90

参数

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

返回值

The IDTSExternalMetadataColumn90 that is mapped to the output column.

备注

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.
