Dissecting SQL Server Execution Plans Grant Fritchey

Execution plans show you what's going on behind the scenes in SQL Server. They can provide you with a wealth of information on how your queries are being executed by SQL Server, including: ? Which indexes are being used, and where no indexes are being used at all. ? How the data is being retrieved, and joined, from the tables defi ned in your query. ? How aggregations in GROUP BY queries are put together. ? The anticipated load and the estimated cost that all these operations place upon the system. Grant Fritchey's book is the only in-depth look at how to improve your SQL query performance through careful design of execution plans. Sample chapters of the ebook have garnered stunning reviews, such as: "All I can say is WOW. This has to be the best reference I have ever seen on Execution Plans in SQL Server. My hats off to Grant Fritchey" Jonathan Kehayias.
