Параметры

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

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

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

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

Возвращаемое значение

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

Замечания

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 Реализация внешних метаданных.
