Use ODBC Driver for Teradata to import values into a UDT column by importing values into tables containing UDT columns in the same manner as is done for other tables. The application handles the UDT columns in the same manner as is done for other tables. The application should handle the UDT columns like it would handle a column containing the external type associated with that UDT. This external type is always a predefined database type. When inserting into a UDT column, the database automatically converts from the external type to UDT internal format.
