This class is intended for PocoData internal use - it is used by StatementImpl to automaticaly create internal BulkExtraction in cases when statement returns data and no external storage was supplied. It is later used by RecordSet to retrieve the fetched data after statement execution. It takes ownership of the Column pointer supplied as constructor argument. Column object, in turn owns the data container pointer.
InternalBulkExtraction objects can not be copied or assigned.
