Parameters

iOutputID: Int32

The ID of the IDTSOutput100 object.

iOutputColumnID: Int32

The ID of the IDTSOutputColumn100 object.

iExternalMetadataColumnID: Int32

The ID of the IDTSExternalMetadataColumn100 object.

bMatch: Boolean

Indicates whether the columns match.

Remarks

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 that you want to allow the mapping to occur.

For more information about working with external metadata columns, see Implementing External Metadata.
