The Teradata Access Module for OLE DB supports only Teradata versions of UDTs and ARRAY data types for export operations where the source is a database. The OleLoad GUI will use the external data type with which a UDT is defined when table/view is selected, copying the external data type to the destination.
The Teradata Access Module for OLE DB will not create UDT or ARRAY data types at a destination even if the destination is a database.
