Retrieving UDTs with FastExport
The Teradata FastExport utility can retrieve values from tables containing UDT columns in the same manner as is done for other tables.
If the select‑list of the SELECT statement used in the Teradata FastExport job contains a UDT expression, the Teradata Database server automatically converts the UDT data to its external type before returning the data to the Teradata FastExport utility.
As such, the data written to the output location referenced by the “.RETRIEVE” command will be in the external type associated with the UDTs.
