I am very pleased to announce that my new book “Expert T-SQL Window Functions in SQL Server” is now available! This book covers everything I talk about in my two window function presentations plus even more material. I am also thrilled that BI Guru Clayton Groom wrote Chapter 9 of the book containing even more real world examples. I believe that T-SQL enhancements don’t get the press and excitement that they deserve. I hope that by writing this book, I can help spread the word about the most useful features added to T-SQL in more than a decade.
