Trang 7Acknowledgments
I said it last time, and it bears repeating: writing a book is really hard Once again, a team of people were
assembled to make this entire thing possible From Apress, Jonathan Gennick, thank you once more for placing trust in me to deliver on this crazy thing and all the help you’ve provided; I begged Joseph Sack to come back
for one more pass through this book of ours, and I’m so grateful that he agreed to put up with me again There’s
no way this book would be worth much without you, Joe Thanks to Anita Castro at Apress for putting up with
my poor behavior and keeping me on schedule Everyone, you did the hard work, and it really shows As before, anything that’s wrong with this book is not from anything that you did Thanks
I still have to throw a hearty thanks to all the members of The Thread over at the SQL Server Central forums Steve, Gail, Jeff, Jack, Barry, Lynn, Paul, and all the rest I haven’t mention specifically—thank you for all the help over the years
I work for the greatest company at Red Gate Software Gareth, Ben, Neil, Simon, and all the team have
provided me with so much that there’s no way to list it all I will mention that I used the Red Gate tool, SQL
Prompt, to write and format all the T-SQL code in this book
While I’m mentioning work, I also want to once more thank the team at FM Global, where I spent ten years learning everything the people there had to teach me Thanks, guys
My most important thanks are reserved for my wife and kids I know you guys are well and truly sick of me writing these books all the time; and yet you still let me do it and support me as it happens.I appreciate it and I’ll never do it again, until the next time
