SQL 2014 Developer, Part 03 of 13: Functions

In this course you’ll learn about the three kinds of UDFs available in SQL Server and will see several examples of functions and how to use them. We’ll start by looking at scalar functions that return a single value, and then will explore the two types of table-valued functions. These latter functions let you return a table data type that acts like an in-memory table. Once you understand how to create functions, you’ll realize that now you have almost too many options for writing code: views, stored procedures, the different kinds of functions, and others. So we’ll discuss how to decide which kind of code module to use in different situations, as well as some potential performance issues with using functions.

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.
