Teradata SQL: Functions, Data Conversions, and Working with Time Overview/Description Target Audience Prerequisites Expected Duration Lesson Objectives Course Number Expertise Level Overview/Description
Teradata supports the use of functions, expressions, and operators to perform operations on data. It generally takes an argument or expression and performs an action for an output. This course will demonstrate the different types of functions used in Teradata, including attribute, string, and analytical functions. It will also demonstrate how to perform data conversions and computations, use SET operations, and work with times, dates, timestamps, and intervals.
