 SQL Server Execution Plans by Grant Fritchey(1st Edition, June 2008) Download eBook (PDF): Free " Every day, out in the various SQL Server forums, the same types of questions come up again and again: why is this query running slow? Why isn't my index getting used? And on and on. In order to arrive at the answer you have to ask the same return question in each case: have you looked at the execution plan? " – Grant Fritchey | |

| Editorial Review 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:
All this information makes the execution plan a fairly important tool in the tool belt of database administrator, database developers, report writers, developers, and pretty much anyone who writes TSQL to access data in a SQL Server database. Given the utility and importance of the tool, you'd think there'd be huge swathes of information devoted to this subject. To be sure, fantastic information is available from various sources, but there really isn't any one place you can go to for focused, practical information on how to use and interpret execution plans. This is where my book comes in. My goal was to gather as much useful information on execution plans as possible into a single location, and to organize it in such as way that it provided a clear route through the subject, right from the basics of capturing plans, through their interpretation, and then on to how to use them to understand how you might optimize your SQL queries, improve your indexing strategy, and so on. Specifically, I cover:
Along the way, I tackle such topics as SQL Server internals, performance tuning, index optimization and so on. However, my focus is always on the details of the execution plan, and how these issues are manifest in these plans. If you are specifically looking for information on how to optimize SQL, or build efficient indexes, then you need a book dedicated to these topics. However, if you want to understand how these issues are interpreted within an execution plan, then this is the place for you.
