 Great Studyguide for the Exam, and good overall SQL reverenceApr 27, 2010
By J. Pelaez
"Tony"
The Oracle SQL Certified Expert exam covers several topics that are not covered in books that are geared towards the SQL Fundamentals exam. It is for that reason that I purchased this book to use as a study guide for the Oracle SQL Certified Expert exam. I recently passed the exam and give full credit to the time I spent going through this book and taking the practice tests.
The books assumes a little knowledge of SQL but I think it is a great guide for both beginners, and experts alike. It is well organized and has a great index. You can read it from beginning to end and it makes logical sense, or you can simply use it as a reference to look up the portions you are interested in. Because the book is geared towards passing the exam and not simply to provide more general SQL knowledge, you won't find any examples that you work on, alongside the book, as you read. Some people might find it hard to learn that way, but for me it was great. I didn't need to have a computer in front of me to try out the code to understand what it meant. This also allowed the book to focus on some of the more subtle and conceptual aspects of the SQL language and how Oracle has implemented it. I think that is key to having passed the exam. Because the book teaches the concepts behind the SQL language, instead of just giving syntax examples, it helps you correctly answer questions that might not directly relate to examples given in the book. For example, the book has a great section on the meaning of "NULL" which is used in a lot of "trick" questions. It might not give you all possible examples of where "NULL" can be used in a question, but it does give you a good understanding of what "NULL" means in the SQL context and therefore how to answer questions that could be affected by "NULL" in their code.
My biggest gripe with the book is the fact that it only came with 70 test questions on the CD, and that the CD is Windows only. 70 questions is the equivalent to 1 practice exam. You can download an additional 70 questions from the web after registering with the publisher, but even doing that only gives you 2 practice exams worth of material. It doesn't take long to memorize all the correct answers for 140 questions. I would have preferred the book if it came with at least twice as many questions. I also think its kind of ridiculous that the CD itself is not cross platform. Such practice exams could have been developed in a way which would have allowed me to run it under Mac OS X or Linux. Instead I had to run Windows under virtualization just to take the practice exam.

 Lots of errors, but otherwise okJan 02, 2009
By spinningplate
This book has a lot of errors in, which I would consider to be a problem for anyone actually studying for the exam. I'd also agree that many of the topics tested on the exam are not fully covered here - I have already taken the exam, and several things were questioned that were not mentioned at all in the textbook. In addition, some of the errors were in the test questions and answers in both the book and downloaded material, which is very confusing. Overall I would say this book should only be used as a backup text to something better edited and more comprehensive.

 Helpful but not usefulDec 10, 2008
By H. THOTA
"Book Worm"
The book is a good resource to give you a overview of features.However,it does not reflect the actual exam scenarios.Topics that appeared most in the exam are discussed in lighter vein.
I would suggest people to study the SQL programmer guide rather than exam guide.Once you are done with the detailed SQL pragramming, then you can briskly follow this one.
Gave it one star as I found SQL Programmer guide more useful than this one.This one is worth reading but not very helpful to pass the exam

Covers the material but is verboseAug 10, 2010
By SantoshK
I have used multiple books to prepare for the Oracle SQL Expert exam.
This particular book is unique in that it covers all the topics for the exam (including the following
topics which are hard to find in just one book):
Generating Reports by Grouping Related Data, Managing Objects with Data Dictionary Views, Regular Expression Support, and Hierarchical Retrieval, and a few sections on managing TimeZones, Flashback, and External Tables.
Although this book is comprehensive enough for the examination, I thought the topics were covered more clearly in other books - particularly Oracle SQL by Watson and Mastering oracle SQL by Mishra. If your primary goal is to pass the exam, this book is ideal. Otherwise, study from a combination of aforementioned books.
Pros:
+Covers all the topics for the SQL Expert certification.
+Accessible to someone new to Oracle.
Cons:
-The author repeats himself 3 to 4 times in each section.
-The syntax and the description are verbose ( the syntax is given with an
example query and about a page describing it which could have easily been
replaced by [ ] | etc...)
-The examples are rudimentary and extremely obvious from the discussion

 Book + eBook = Good DealMay 03, 2010
By ESVK
"SVK"
Steve O'Hearn does a good job delivering a very encouraging, personal (as well as informative) tone to the material. While containing much the same material as other Oracle Press SQL books, it does not lift or "steal" any of the wording. O'Hearn has opted to write everything from scratch. The book also lacks the typographical errors that have plagued so many Oracle Press books over the years.
This book's objective is to prepare you for the exam. It is not an exhaustive SQL reference (though certainly robust) - nor does it claim to be. In addition to the book itself, you also have access to the ebook and additional exam simulated questions via the CD. The ebook is in Adobe and isn't formatted quite as well as the Kindle version. The ebook is baked into the price at nearly $40.
There really isn't too much I would offer in the area of improvements - except to have even more exam type questions.
