Paramètres
- lOutputID
Type : System. . :: . .Int32
The ID of the IDTSOutput100 object.
- lOutputColumnID
Type : System. . :: . .Int32
The ID of the IDTSOutputColumn100 object.
- lExternalMetadataColumnID
Type : System. . :: . .Int32
The ID of the IDTSExternalMetadataColumn100 object that is linked to the output column.
- bMatch
Type : System. . :: . .Boolean
Indicates whether the output column and external metadata 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 to indicate that you want to allow the mapping to occur. For more information about working with external metadata columns, see Implémentation des métadonnées externes.
