Review
"There's no fluff of any kind in this book. It's clearly written by someone who has taken a lot of Oracle certification exams and knows what's critically important and what's less so: Here's what you need to know about what's on this test, and then bang-bang-bang through the Oracle 1Z0-047 exam objectives. Each topic includes a condensed explanation complete with relevant syntax, vocabulary, and examples. Their slim size makes them easy to carry with you and realistic to read more than once."Â --Â Anne Martinez -- GoCertify.com

This book is a good outline to study for the Oracle Certified SQL Expert exam. I rated it as a guide not a complete book because the author clearly makes that assertion and also because of the price. It is by no means a singular source for preparation and study. I used this book as a guide more than a source of more comprehensive study materials.First, I start reading through a chapter and look at the examples. If you are honest with yourself, almost all readers will see that they will need to come up with more examples to fully understand the topics in depth. You can play with examples and alter them with the schema provided by the author's website to develop a deeper understanding.Second, I go to the Oracle documentation, which is really good. But, you will still need to cook up some more examples inspired by the Oracle docs. While toying with the examples and constructing your own, you will find ambiguities in the documentation when statements are made and examples are not given.Here is one that I think is a good example of having to dig deeper. This comes of in the discussion date literals with time zones:Without exact quote, the following two returned values should be equatable per the Oracle Docs.SELECT TIMESTAMP '1999-10-29 01:30:00' AT TIME ZONE 'US/Pacific'FROM DUAL;TIMESTAMP'1999-10-2901:30:00'ATTIMEZONE'US/PACIFIC'---------------------------------------------------------------------------29-OCT-99 01.30.00.000000000 AM US/PACIFICSELECT TIMESTAMP '1999-10-29 01:30:00' AT TIME ZONE '-8:00' FROM DUAL;TIMESTAMP'1999-10-2901:30:00'ATTIMEZONE'-8:00'---------------------------------------------------------------------------29-OCT-99 01.30.00.000000000 AM -08:00But notice below:select 1 from dualwhere TIMESTAMP '1999-10-29 01:30:00' AT TIME ZONE 'US/Pacific' = TIMESTAMP '1999-10-29 01:30:00' AT TIME ZONE '-8:00';no rows selectedThe problem is that you cannot mix time zone descriptors. An example where it does work is below:select 1 from dualwhere TIMESTAMP '1999-10-29 04:30:00' AT TIME ZONE 'America/New_York' =TIMESTAMP '1999-10-29 01:30:00' AT TIME ZONE 'America/Los_Angeles'; 1---------- 1This took a bit of research and trial and error but it is a good example of how to use this book with the Oracle Docs.Third, I do have another book that I like very much, "Advanced Oracle SQL Programming". It covers advanced SQL topics in more depth. I always read a topic from this other book as I come upon topics in this book/guide. Then I play with and alter all of the exampls.There are also many sample exams online. If you decide to use them, beware. You must test each question and answer interactively in SQL*Plus by creating tables and writing queries. Otherwise, you can be mislead. These online sample tests can do more harm than good. Also, if the Brain Dump is considered harmful to the certification by Oracle, Oracle can take punitive action against you. This includes decertification and even stiffer penalties. Oracle recommends you test the brain dump by searching the domain/url of the website selling the brain dumps at http://www.certguard.com/search.asp.Again, use this book as a guide. Fill in the blanks with another source and the Oracle online docs.Again:1. Read each topic in this book.2. Test each query.3. Alter the queries to test your knowledge.4. Look at the Oracle Docs for each topic.5. Test the information by creating tables and test queries.6. Read from a deeper source book.7. Test the information by creating tables and test queries.If you do the work, you will not only pass but you will truly raise your understanding of SQL and Oracle peculiarities.
With 17+ yrs of Oracle Development experience, I decided to step up and get certified as an Oracle Developer (not DBA) and knew that just my work experience would not be enough to pass the exam. So in researching I found the 3 developer tracks to get certified and this was one of them and thus this book I purchased.Although the book is short in length of pages, re-reading each chapter as I read it, took me a while (on weekends) and it reinforced what I already knew and exposed me to features of Oracle SQL that I never used in my work experience (i.e. ROLLUP, CUBE). But having said that I now understand those concepts, and they can serve me well in the future.This is an excellent study guide and I also went to Matthew's blog where you can get insights into "how" to study for this exam and "how" to take the exam. And heed his advice.....use OTHER source material in addition to this guide to help in your exam.I'm now reading Steve O'Hearn's big "OCA Oracle Database SQL Certified Expert Exam Guide (Exam 1Z0-047) and once I finish that book I will come back to this Study Guide to refresh my memory.I highly recommend this book and it will be more valuable to seasoned Oracle Developers (5+ yrs of work experience).
I can't speak for everyone else's expectations....butWhen you consider the subject matter and the intended audience (Oracle Database Exam Takers)...This book delivers 100%.... This is an EXCELLENT study guide for this exam and it's worth every penny of it's purchase price. In fact, this book is a bargain!OK, as others have mentioned, it is not an "exam guide" per se. There are no practice exam questions etc. and they are right, this book should not be your only exam resource.However, as a study guide, it is a very useful, and very well thought out. All of the information presented is relevant to the exam. It is very practical and its presented in a concise, easy to read and digest format. There is no fluff or filler. Just a great study guide, which I believe is what it's supposed to be...I have no problem giving Mr. Morris a high-five here.... Great job! Highly recommended!!
What I love the most about this: the companion website –– which provides the code for the objects referenced in the book, along w/ applicable oracle documentation, useful articles, and video tutorials that Matthew Morris brilliantly compiled together.Also on the website is an affordable practice exam ($14.50 first attempt and $11 for retake).FYI, there is a promotional code in this study guide (page 13) that reduces the purchase price.
few small grammatical errors but not enough to warrant any stars removedthis book is an excellent source for review of this certificationNO FLUFF JUST STUFF :)might be a bit scant for people starting to study for the exam, but you could use the internet to look up terms you're not familiar with for further studythis is very much like an O'Reilly pocket guide for studying for 1Z0-047 :)
This book covers all topics in the IZ0-047 test and for each topic the author provides an explanation, the syntax, and an example. I would highly recommend this book. This would be a perfect complement with a more comprehensive Oracle SQL book, for the sake of a more in-depth look and further examples if you are still not getting the idea.
Pros:+ This book covers all 1Z0-047 exam topics with large number of SQL examples+ It's small and good for quick exam topics review+ It's cheapCons:- It lacks detailed topics descriptionI would recommend this book as an additional source for exam preparation, but reading it only is certainly not enough to pass the exam.
I think this book is very good to make a review before taking the exam. The subject is not deeply covered, but all the topics are there and is an excellent guid to use as a reference for researching.
