Or, get it for Kobo Super Points! See if you have enough points for this item. SQL Tuning provides an essential next step for SQL developers and database administrators who want to extend their SQL tuning expertise and get the most from their database applications. There are two basic issues to focus on when tuning SQL: how to find and interpret the execution plan of an SQL statement and how to change SQL to get a specific alternate execution plan. SQL Tuning provides answers to these questions and addresses a third issue that's even more important: how to find the optimal execution plan for the query to use. Author Dan Tow outlines a timesaving method he's developed for finding the optimum execution plan--rapidly and systematically--regardless of the complexity of the SQL or the database platform being used. You'll learn how to understand and control SQL execution plans and how to diagram SQL queries to deduce the best execution plan for a query.

Itzik Ben-Gan has been mentioned over times here on stackoverflow , but I couldn't believe it to find not a single mention of him here on this performance tuning question. As an additional resource, you can also find some videos of Itzik talking about performance related stuff here on youtube. What resources exist for Database performance-tuning?

Like Dan, I have been doing Oracle for a long time since I offer three opinions about Dan's book: In learning to do the diagrams, you will understand the basic logic and basic math that an optimizer must do in order to get you a good plan. Do not worry. It is not a deep math book and there are no complex calculations.

Indeed Dan shows you how basic it all really is. As I said, I have been doing Oracle since And Dan explains it well. Unfortunately about the time Dan published the book , Oracle was entering a revolution in its design. Don't get me wrong, even outdated, this book has great value because it clarifies what you need to tell other people, why certain things happened.

Page has a gem of a trick that I never considered but which I can see as offering massive benefits in a few special situations which I have faced in the past but could not solve.

Thanks Dan. It is even easier to do in today's 10g and 11g databases because you need no hints to make it happen. This brings me to my last commentary. The reason I say the book is outdated is because Oracle has come so far in the last five years with its optimizer that the trick to getting Oracle to give you the right plan is to feed it good information.

If you do this then it will do what Dan shows you in this book only better than you could and give you a great if not best plan. Thus you will rarely build a query diagram these days.

Instead you will try to figure out where information was not provided to Oracle correctly and fix that. If this turns out not to be the case, then the problem is likely because the SQL is crappy and you need to rewrite it. Many times your system won't be that complicated.

Not being an expert in DB2 or Sql Server I cannot say how up-to-date the material remains on these databases but since I doubt their Optimizer Technology is as advanced as Oracle's there may yet be significant value retained in these two spaces.

I can say that it is true that Dan's diagramming methods are universal for any database and that reading the book will provide you with that boost towards critical mass I mentioned earlier regardless of what database you use. Maybe its time for Dan to do an updated version of the book. One last comment. I don't want this to seem like a negative review. Remember I said I have been doing Oracle since As "expert" as I am with Oracle and in tuning it I am a reasonably good tuner for most things , I learned stuff from Dan and his book.

Twenty Five years of doing it and this book still taught me things.

I am very happy to have downloadd this book and you will be too. Hail Flavius! You have to read some paragraphs two or three times to understand what author wanted to say; 2. Why provide them then? What's the point of giving test db that can only be partially filled with data? The point is supposed to be in comparing the results and trying by yourself and not in trying somehow to match the result to the book and wondering why author gave you scripts that don't work; 4. And this form won't work in SQL server without alterations; 5.
