Does not cover required functionality!
By Michelle
This book is a waste of money. The author presents examples as if this were the first time one has ever encountered SQL. And if you think you can pass the exam based on knowing everything in this book... you will fail. The exam is extremely complex. Near every question on the exam involves dual or multiple concepts, and the choice of answers is not simply "pick the right one answer", it is "pick all the answers that are correct". Thus, if there are 4 answers you do not have a 25% chance of getting it right, because maybe 1 is correct, maybe 2, maybe 3. The exam also is chock full of HEAVILY nested queries. Not the type that you can quickly recognize, you need a pencil and lots of paper.... but the exam center only gave me a crappy thick marker and a single dry erase sheet. My hands were a mess. This book does not come close to demonstrating the complexity of the questions in the exam. And like another reviewer said... this book does not touch ANY new 12c functions like, Fetch First x Rows Only, or Offset x rows. I am hugely dissatisfied.

A great book to prepare for the exam, or brush up on fundies.
By Timothy L. Dillon
I think the information presented is laid out in such a way to teach the material easily and efficiently. I have read several SQL books (mostly from O'Reilly) and believe this to be a good foundation and as good as if not better than the best ones they have to offer. The concepts were all known, but I still found myself learning and it gives wonderful tips on what to expect and how to adjust your thinking for the exam. I am very happy with this purchase all around and hope that books for subsequent books are put together as well as this one.

Terrible at preparing you for the exam
By Q. Zhang
Suppose you were 16 years old and getting your driver's license for the first time. You apply to the DMV, and they send you a transportation rulebook. You buzz through the book, you ace the end-of-chapter questions and easily pass the officially sanctioned practice exam included with the officially approved study materials.
Then you take the test and find that a substantial chunk of the questions are about things that were not covered in the book, and that most of the questions are not simple "pick one" questions of the practice test but "pick two/three/all correct answers of five" which eat up time like nothing, and that for some of these, there are more correct answers (proven by actually trying the hypotheticals in question) than are provided.
I suspect I'm going to get a bunch of Oracle apologists on my case right about now, yammering about how of course it's hard, they can't just hand out certificates willy-nilly. Or that I'm bitter because I failed the test and am just venting.
It is true that I failed the test and am venting, which means that this review should be considered more accurate, not less, for the simple reason that I actually took the test and thus am in the best position to judge whether this book was adequate preparation. The test asks several questions about the FETCH FIRST functionality which was nowhere in the book. It asks several questions about LISTAGG which was nowhere in the book. When working through this book, I tended to either get 100% of the end-of-chapter questions correctly, or miss literally one or two at most. When doing a blind run through the included practice test (that is, I finished working through the chapters and decided to take it without reviewing previous notes), I scored an 85%. All of this translated to a 55% on the actual exam. Think about that, an 85% on the OFFICIAL PRACTICE EXAM = 55% on the ACTUAL exam. At best, somebody was sleeping at the wheel when the practice materials were created, and at worst, it's nothing but an additional revenue stream for Oracle.
The test should be challenging and thus require you to have a solid grasp of the material, not cause you to fail by asking you questions that were not in the official material. That's not a certification, that's a con.
Edit: also, the instructions to actually setting up the sample DB are nonexistent. Not even the other book on 12c, Installation and Administration, gives you any idea. I had to search for this youtuber (RebellionRider) whose channel had a tutorial that did in 10 minutes what several chapters in the book could not.
