UDF User Guide

This user guide describes the Teradata Warehouse 7.1 User Defined Function (UDF) feature. This guide is primarily targeted towards developers of UDFs and database administrators. For the most part SQL language users of UDFs are unaware of the difference between UDFs and System Defined Functions and so a limited amount of discussion is required on using UDFs in the SQL language.
