    This is my review 3 months after I bought the book but just 2 days after taking the exam......and PASSING it on the first try! This is the 2nd book that I read after first reading Matthew Morris' Study Guide for 1Z0-047: Oracle Database SQL Expert: Oracle Certification Prep.That one is a small guide (150 pages). Steve O'Hearn's books is 700+ pages. Though I have 17yrs of experience, I knew my SQL knowledge was intermediate but after going through this guide, saying it was intermediate was barely enough. I now TRULY feel that after reading this book and Morris' guide that I feel way more comfortable in saying "expert", but "expert" truly comes with real-world experience. But the guide will help. The end of chapter quizzes and also the accompanying practice exam CD definitely helps.My advice is do NOT take the practice exams on the CD until you are VERY close to feeling comfortable in taking the real-world exam. And when you do take the exam take them as close as possible to the real exam. Whatever settings there are make sure they mimic the real world.I studied from mid-April to mid-July, so a total of 3 months and this helped me PASS the exam. It is 120 minutes long (2 hours) and 70 questions total and you must get a minimum percentage right to pass. 66% is passing. Not 66 questions! As that would be a minimum of 94% passing. At that rate, very few people would pass. I got a 78% (55 out of 70). I used up EVERY second. I had 45 seconds left to spare to go over any questions I had marked but alas had little time.Study long and slowly and take your time, as there's no rush to take the exam. They're offered daily. And good luck.

    Warning. This book is copyright 2010. The cover says "bonus exam available with free online registration". However when I tried to activate that feature, the web site stated "This LearnKey/McGraw Hill program is no longer accepting new users."That was disappointing. The online practice exam was pretty good. I studied up some more after taking it and was hoping to try out the bonus exam.Questions at the end of each chapter are enlightening. The book is big and covers lots of material. Make sure you use other sources such as Oracle Certification Prep - Study Guide for 1Z0-047.

    As someone who has been working with Oracle for years, I was pretty confident about my SQL knowledge but I decided to buy this book anyway in order to fill some small gaps that I noticed when I checked the topics covered in the exam. I am glad that I did, because the gaps were a little bit bigger than I thought and some of the topics I was feeling very confident about needed some polishing.As I am used to working with strict naming conventions, a basic question such as whether or not is possible to give the very same name to a table, an index or a constraint never occurred to me before (the answer is yes, as they belong to different namespaces). I also thought that I knew perfectly well everything related to joins but I found little surprises such as a predefined keyword for the Cartesian product (CROSS JOIN) or that a column of datatype TIMESTAMP WITH LOCAL TIME ZONE can be used as a PK but a column of datatype TIMESTAMP WITH TIME ZONE cannot.The book is well organized and it covers point by point the objectives of the Oracle exam. The examples are well chosen (no need to be in front of your computer) and the way the author explains each topic is so clear that the book could also be used by a beginner as a learning tool. I could only spot a small typo (SEELCT instead of SELECT on page 521) and probably one of the questions on a self test about the use of a pseudocolumn on page 163 that could have been improved a little bit: SELECT ROWNUM, * FROM PORTS ORDER BY PORT_NAME;It fails with a syntax error but the author didn't mention that it can be solved by using an alias: SELECT ROWNUM, p.* FROM PORTS p ORDER BY PORT_NAME;But these are really unimportant details. If you have not taken any Oracle exam yet, the one provided with the book will give you a very good idea about what to expect, but be warned that questions in the exam are a little bit harder. For me, this book was a key element for passing the exam and I can surely recommend it.

    This is a great book, covering all of the relevant topics in detail. The chapters and sections are in the order the certification objectives appear on Oracle's 'Exam Topics' page for this test, so it's easy to navigate and find your trouble spots. There are over 200 end-of-chapter questions in the book, and that's all I used to study for this exam. After only a week of study, I passed the exam with no other preparation except for the experience I've gained over the short time I've held my job. I can only imagine how well I would have done if I registered later for the test and gave myself more time.I initially deducted a point from my review over the Windows-only nature of the included CD (waah, waah, whiny Linux user), but looking back I sincerely believe that this book's printed content alone makes it well worth the low price. It contains all the material you would find in a thousand+ dollar course in an easy-to-navigate, well-written package. You should definitely purchase it if you are planning on taking the Oracle SQL Expert exam.
