Parametri

  • bMatch
    Tipo: System.Boolean
    Indicates whether the output column and external metadata columns match.

Valore restituito

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

Osservazioni

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 Implementazione di metadati esterni.
