Apply powerful window functions in T-SQL—and increase the performance and speed of your queries
Optimize your queries—and obtain simple and elegant solutions to a variety of problems—using window functions in Transact-SQL. Led by T-SQL expert Itzik Ben-Gan, you’ll learn how to apply calculations against sets of rows in a flexible, clear, and efficient manner. Ideal whether you’re a database administrator or developer, this practical guide demonstrates ways to use more than a dozen T-SQL querying solutions to address common business tasks.
Discover how to:
- Go beyond traditional query approaches to express set calculations more efficiently
- Delve into ordered set functions such as rank, distribution, and offset
- Implement hypothetical set and inverse distribution functions in standard SQL
- Use strategies for improving sequencing, paging, filtering, and pivoting
- Increase query speed using partitioning, ordering, and coverage indexing
- Apply new optimization iterators such as Window Spool
- Handle common issues such as running totals, intervals, medians, and gaps

Free Microsoft SQL Server 2012 High-Performance T-SQL Using Window Functions
This book is a refreshing alternative to the usual 900 page everything-and-the-kitchen sink tomes that seem to dominate this genre.
Instead, it is focused and concise (200+ pages). And extremely well-written, by someone who clearly takes his teaching role seriously. Beyond just describing how to use the window functions, it does a great job of delving into the background needed to really understand how & why they work as they do.
In addition to describing SQL Server 2012 support for window functions, the book also details those areas in which full support for standard SQL window functions has not yet been implemented in SQL Server. It also suggests improvements that could be made to both the standard and to MS SQL.
Whenever possible, the book gives alternative queries constructed without the use of window functions. This is great as both a learning tool, and to convince you that in general you don't really want to go that route (non-window) if at all possible.
If you want to learn both the subtleties and quotidian uses of SQL window functions, get this book. Your brain will light up with new possibilities.
(If it helps credibility-wise, check out my mostly negative review of the same author's "Inside Microsoft SQL Server 2005: T-SQL Programming"--I am the proud holder of the "Most Helpful Critical Review" honor for that title. Ben-Gan's lucidity has increased considerably with this current effort.)

One of the good "Cheat" book I came across. Yes, I agree with many that there is no doubt Itzik Ben-Gan is one of the great T-SQL experts in the industry. Initially I thought many of the functions he described cannot be used in OLTP model. Very quickly I realized I was wrong to some extent, I had to identify duplicate entries and Islands and the queries were right there. But I think I will stick to my Original Comment - the book is very specific for certain window function as the title suggests which are - ranking, distribution, ordering, getting ranges, gaps, island, duplicates, running totals, packing intervals, aggregates and finally optimizing them. Ofcourse that's what the title suggest (Window Functions..) and is very well concised in 200 odd pages when compared to 900 or so in other books. Actually I was expecting - to know different alternatives for creating such functions, which I did not find much. There is a mention of CLR, but one should be good with .NET coding. My final conclusion would be go for the book in case you have to deal a lot with analytical type of coding. This is the book, where we can simply use the proven logic.
