Find some examples in the various pieces of Teradata-specific SAS documentation:
SAS/ACCESS 9.1.3 Supplement for Teradata (SAS/ACCESS for Relational Databases), Second Edition**
This supplement explains how SAS/ACCESS software has been customized to accommodate the particular requirements and capabilities of your DBMS.
if you don't already have the book, I would recommend buying it : e.g.from
http://www.sas.com/apps/pubscat/bookdetails.jsp?pc=60844
(as I like both paper and searchable-electronic versions : ) It is available for download at
http://support.sas.com/documentation/onlinedoc/91pdf/sasdoc_913/access_teradata_9298.pdf
SAS online doc for the web, points to Teradata at
