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." -- Anne Martinez -- GoCertify.com

a Vital Part of my Studying Process
By Amazon Customer
The first thing that prospective buyers need to be aware of is that this book is a STUDY Guide not an EXAM Guide. The distinction between the two is that this book is a tool intended to aid your studying process, and not intended to cover the depth of knowledge required to pass the exam. So while this book is an incredibly helpful resource, you absolutely do still need to seek out several additional resources to use in addition to this book.
That said, it is precisely because of the concise nature of this book that I found this book useful in three key areas throughout my studies:
1) First, I did one complete read-through to determine which sections are initial weaknesses and to emphasize exactly what will be on the exam.
2) As I moved onto other resources, I referenced back to this book periodically to make sure that I'm covering the entire scope of each section.
3) Once I felt that I was done studying, I did one last complete read-through of this book both as a basic review and to make sure that I felt comfortable with all of the material.
I just couldn't imagine reading some of these 700+ page tomes multiple times like I was able to read this one (though those books still make useful additions). Because this book is so small and concise, I have found that it fills a previous void in study materials available and would recommend it to anyone taking this exam.

A Good Outline to Study for the Exam
By David Bradford
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/PACIFIC
SELECT 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 -08:00
But notice below:
select 1 from dual
where 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 selected
The problem is that you cannot mix time zone descriptors. An example where it does work is below:
select 1 from dual
where 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
----------

This 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.

Good as additional source
By Alexandr Tretyakov
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 cheap
Cons:
- It lacks detailed topics description
I would recommend this book as an additional source for exam preparation, but reading it only is certainly not enough to pass the exam.
