Paramètres

iOutputID
Type : System. . :: . .Int32
The ID of the IDTSOutput100 object.

iOutputColumnID
Type : System. . :: . .Int32
The ID of the IDTSOutputColumn100 object.

iExternalMetadataColumnID
Type : System. . :: . .Int32
The ID of the IDTSExternalMetadataColumn100 object.

bMatch
Type : System. . :: . .Boolean
Indicates whether the columns match.

Valeur de retour

Type : Microsoft.SqlServer.Dts.Pipeline.Wrapper. . :: . .IDTSExternalMetadataColumn100
The IDTSExternalMetadataColumn100 that is mapped to the output column.

Notes

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 Implémentation des métadonnées externes.
