매개 변수

반환 값

유형: Microsoft.SqlServer.Dts.Pipeline.Wrapper.IDTSExternalMetadataColumn100
The IDTSExternalMetadataColumn100 object that the input column is mapped to.

주의

This method is called to map an input column to a column in the ExternalMetadataColumnCollection of the input. When you are developing a custom data flow component, you override this method, to ensure that the input column 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 외부 메타데이터 구현.
