Table Vars & Temp Tables – What you NEED to Know!

Almost every SQL Developer is familiar with Table Variables and Temporary Tables. While each of these objects represent temporary storage, there are also substantial differences between them. Understanding the differences between Table Variables and Temporary Tables, and the ramifications that those differences cause, is essential to being able to properly select the appropriate object for use in your development tasks. In this code filled session, we’ll discover the differences and similarities of Temporary Tables and Table Variables, dispel some widespread myths about each, and answer the most important questions of them all, “When do I use one or the other and what are the various impacts of doing so?”

Minimally Invasive – Tools to Doctor Up Your Code

This code filled session examines several additions to recent versions of SQL Server. These tools allow you to perform minimally invasive surgery on your code and gain performance! Learn how the APPLY operator works; iterate through incoming data just once with the MERGE statement; “slice and dice” your data with the Windowing (ranking) functions; re-write your multi-statement table-valued functions to inline functions to help the optimizer and speed up your queries; learn how to create a grouped delimited list – without loops!

Windowing Functions in SQL Server 2012

SQL Server 2012 brings with it nearly full ANSI compliance with the windowing functions. Come to this code filled session to learn about all of the windowing functions in SQL Server 2012: Ranking functions, changes for windowing in the Aggregate functions, and the new Analytic and Sequence functions. We’ll examine how this latest implementation of the windowing functions allows us to perform running and sliding aggregations; retrieve data from adjacent rows in the partition, and much more – all without self-joins back to the source table.
