ODBC Driver for Teradata can be used to import values into a UDT column. Use ODBC Driver for Teradata to import 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 Teradata Database type. When inserting into a UDT column, Teradata Database automatically converts from the external type to UDT internal format.
