Introduction
Sometimes all one wants is a good example. at’s our motivation for accepting the baton from Joe Sack and
revising his excellent work to cover the very latest edition of Microsoft’s database engine—SQL Server 2012.
T-SQL is fundamental to working with SQL Server. Almost everything you do, from querying a table to
creating indexes to backing up and recovering, ultimately comes down to T-SQL statements being issued and
executed. Sometimes it’s a utility executing statements on your behalf. Other times you must write them yourself.
And when you have to write them yourself, you’re probably going to be in a hurry. Information technology
is like that. It’s a eld full of stress and deadlines, and don’t we all just want to get home for dinner with
our families?
We sure do want to be home for dinner, and that brings us full circle to the example-based format you’ll nd
in this book. If you have a job to do that’s covered in this book, you can count on a clear code example and very
few words to waste your time. We put the code rst! And explain it afterward. We hope our examples are clear
enough that you can just crib from them and get on with your day, but the detailed explanations are there if you
need them.
We’ve missed a few dinners from working on this book. We hope it helps you avoid the same fate.
Who This Book Is For
SQL Server 2012 T-SQL Recipes is aimed at developers deploying applications against Microsoft SQL Server
2012. e book also helps database administrators responsible for managing those databases. Any developer or
administrator valuing good code examples will nd something of use in this book.
Conventions
roughout the book, we’ve tried to keep to a consistent style for presenting SQL and results. Where a piece of
code, a SQL reserved word, or a fragment of SQL is presented in the text, it is presented in xed-width Courier
font, such as this example:
SELECT * FROM HumanResources.Employee;
Where we discuss the syntax and options of SQL commands, we use a conversational style so you can quickly
reach an understanding of the command or technique. We have chosen not to duplicate complex syntax
diagrams that are best left to the ocial, vendor-supplied documentation. Instead, we take an example-based
approach that is easy to understand and adapt.
