Introduction

Dynamic SQL is often described in bits and pieces, often when a need for code arises and time is limited.

This book is an opportunity to put as many of those fragments together into a meaningful journey, from

defining the technology to delving into its deepest and most complex aspects. This is a dive into many

topics that are extremely important when working with any database. It will intentionally delve deeper into

performance optimization, application development, and security than may seem necessary.

What Is This Book?

This is meant to be a discussion of smart database design and architecture, with a focus on Dynamic SQL.

If any topic that is covered in an aside feels incomplete, it is because there simply isn't room in these pages

for a thorough analysis of all of them without losing focus on why you are here. Dynamic SQL is often

underused, misused, or overused. The many tangents into other arenas of design and development serve

as guides to keep you on track and emphasize the value of well-written database queries as well as ensuring

that you use Dynamic SQL for the correct applications.

Each chapter delves into a specific topic and attempts to go into as much detail as possible, while also

providing multiple examples to demonstrate it in the simplest way possible. If you have never written a line

of Dynamic SQL, this will be an opportunity to learn, practice, and immediately apply it. If you already have

experience in writing and using Dynamic SQL, this will be a chance to learn new applications while getting a

refresher on those you have worked with in the past.

Intended Audience

Anyone with a healthy interest in database administration or development can benefit from the topics

covered in this book. Each chapter starts out with basic definitions and examples, providing an easy entry

point for professionals with any level of experience. The book transitions into more advanced techniques,

allowing you to not only learn the basics of an important subject, but also to gain access to scripts and ideas

that could be tested and used to solve problems you may face in your everyday experiences.

If you have a particular interest in database security or optimization, you will appreciate the focus

on these topics in each chapter. SQL Injection gets an exhaustive review, with many different aspects and

examples presented to ensure a thorough explanation of this important topic! Every chapter, regardless of

topic, will reference performance whenever possible. It is an oft-made mistake that a database is designed

with little data and few users, ignoring the possibility that it will one day grow into a behemoth. Reminders

are placed throughout this book to consider query performance at all times, even when performance may

seem “good enough”.
