  What I'm missing or doing wrong?

  I read "Oracle Database 11g: SQL Fundamentals I: Oracle Certification Prep" by Matthew Morris and a few months made uCertifys prepkit for her, until I received more than 75% every time on practice tests with 40 mins flying over! BUT WAIT WHAT HE... I failed the exam the other day terribly! Being an online test and I have same time left more to look for anything, for I was not sure about the thought, I thought I was well prepared.

  The review was for most of the exercises with several possible answers, so when in doubt one is bad then the question is wrong. Very few quick questions like "which is not a function of the single line". As 90% where problems/exercises who needed to read the requirements and analysis of multiple SQL queries for what (did or did not) meet the requirements. I was so anxious that I had no time to work on each issue to understand the issues and to provide a real answer. Only "very probably with time I got ' responses. Basically an assumption (with multiple true/false addresses its practically unlikely to get from a guess)

  I found it didn't test "Oracle SQL" only, but your ability to problem solve quickly. So I bombed despite I know everything in the guide and I'm now not sure what to do next, as I know the content well, I just suck to solve these exercises within 2 minutes of each. (Are there copies of the latest test questions out there that people use to go I don't know! or I just suck at examinations.

  >.. are been done uCertifys prepkit for her, until I received more than 75% every time on practice tests with 40 mins flying over!

  Practical examinations again and again and again until you get a high score is not useful... it's just fool yourself into thinking that you are ready.  Practice exams are better used to assess how ready you are after you have made all other preparations.  Even in this case, the score only means something the first time or two you take the examination practice. After that, your score is not really what you know on the subject, but what do you remember the last time you answered these questions. I talk about this in the following article:

  > I found it didn't test "Oracle SQL" only, but your ability to problem solve quickly.

  120 minutes for 66 issues (dry 109 / question), 1Z0-051 is in fact one of the exams less limited time oracle has. One of the really bad is 1Z0-144, which is 70 questions in 90 minutes (dry 77 / question).  That said, the 1Z0-051 exam * has * to be a bit constrained time.  As a review unmanaged, if he allowed far too much time, it would be too easy to simply seek the answers to the questions in a reference book (who is cheating, BTW).

  > Review was especially exercises with several possible answers, so when in doubt one is bad then the question is wrong.

  I would say the majority of the Oracle exam questions are multiple-answer, Yes.  With these, if you get a bad part, the whole question is wrong (i.e. If you are supposed to choose three answers and you get 2 right, you do not get credit 2/3).  If the correct answer is not immediately obvious to me, so I watch each of the answers to find those who have something clearly incorrect and remove them.

  > Are there copies of the latest test questions out there that people use to pass that I'm not aware of!

  There are always people who find a way to cheat at exams.  It is a way, and people who do this are endangering their certification status and lowering of the value of the certification.

  You don't mention my guide uCertify, but no sources or other preparation.  You have experience writing SQL?  On the front of the guide on the preparation for the exam, it indicates that you should have spent queries execution time of writing, and to see the result before programming the test.  He also stated in the same section as the candidates again in SQL, you must complete the information with data from other sources and suggests the companion site.  This site Details exam 1Z0-051 page has links to articles and videos that will help you learn more about Oracle SQL - all available for free.

  I'd say the next step would be to go to the details page to review for this review and find out some (or all) of the SQL tutorial videos.  There are several different video series of different instructors.  Choose the instructor that seems to suit you best or to display several series.  Look at one of these should give you a better grounding in SQL.  You can read some articles available on the page.  Installation Oracle XE and practicing writing SQL statements is also a very good way to cement the information contained in your brain.  At this time, read through the guide.  It focuses on the topics specific to the review, but if you know little about SQL, there is no way to put information in context.  Details for 1Z0 - 051 page is here.

• 11g SQL Fundamentals SQL expert?

  Hi gurus,
  
  I'm getting confused in selecting the proper test. Oracle says that if the exam is difficult then required pass mark will be low compared to other tests.
  
  I heard that the expert SQL (1Z0-047) is a little difficult to compare to 11g SQL Fundamentals(1Z0-051). But for the Expert SQL pass mark is high and also the price of the examination.
  
  Any idea why is there a difference in pricing and passing also. And also suggest me what test I have to attend.
  
  
  Below, I have copied the link.
  
  [http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=138#2_6]
  

  For example, to maintain a consistent standard for success, a new version of an exam, which contains more dificult questions than the prior version will be assigned a somewhat lower required passing score. For this reason, passing scores may vary between different exams in your certification track, and between later and earlier versions of the same exam.

  Thank you
  Suri

  Oracle says that if the exam is difficult then required pass mark will be low compared to other tests.

  This isn't what the text says, what he says is: "...". a new * version * review, which contains more difficult questions than the * previous version * will be affected a little lower required passing... »

  OE is not 1Z0-051 vs 1Z0-047 because they are not of the different versions of the same test. The statement says that, if they pass a test, do a version update, but find that the new version has more difficult questions, they could slide the pass mark so that it is not more difficult to pass than what it replaces.

  Any idea why is there a difference in pricing and passing also.

  1Z0-051 is available online (i.e. not managed). It's cheaper because this method costs Oracle less to offer. My opinion is that it reduces considerably the value of spend because it is too easy to cheat, but is a completely different topic.

  The only relationship in the two tests is that they both cover SQL. They do so at very different levels of difficulty. Scores between these two tests have no relationship between them. OE sets the pass mark for individual tests at a level designed to allow a certain percentage of candidates to the exam. I don't know what level or how they determine. My conviction is that this score is determined initially as they treat the results of beta testing. If I'm not mistaken, then they take a note of passage based on beta responses which would allow their percentage target of candidates. Maybe it's that they adjust scores of passage early in the life of a review of production if they find that the beta "good percentage" was atypical, but that's just speculation.

  And also suggest me what test I have to attend.

  I wrote an article discussing the two tests and why you might throw on each other a few months ago:

• Passed 1Z0 - 051 - is the final score?

  Hi all
  
  Chasing "Oracle PL/SQL Developer Certified Associate' certification. Just finished online ' 1Z0-051-Oracle Database 11g: SQL Fundamentals I '. After review, I get a summary containing for example "Score from 60% ' and my current score, which is" Pass (67.3%) "" ».
  
  According to what can be seen on the official Oracle site describing "Oracle Database 11 g: SQL Fundamentals I ', 'Note subject to changes of passage'.» How does it relate to me? If I had information after the confirmation of the review that I spent, I thought I really spent, or rather is located and must wait for some kind of additional confirmation, as the "Note of passage subject to change"?
  
  Just a little confusion.

  My interpretation:

  'They' say simply that the official level pass could change in the future. (In other words, they are sayig the website could be the problem.)

  If Oracle decides to change the level of passage, in the future people have need to reach the new level of pass to pass. Passes and existing scores are grandfathered.

  However, you have received an official piece of paper that says you spend. Save it for your files. You can be comfortable that the score is final and that you lack.

• Advisor-1Z0 - 051

  Hi all

  I took 1Z0-051 last night after several months of study and has a 3 percentage points. Basically, I ran out of time. I knew how to answer most of the questions, but the motions were simply too much time for me.  Any advise? I wasn't expecting 2 hours of extreme concentration, with most of the questions to be with several narrow answers queries.  I don't know yet how to study or what I did differently.  Is there a good strategy I don't see?   Basically, I ran out of time and had to score the last 10 questions randomly.  I mean common Oracle, which is wisdom here?

  Time management is always a factor in the certification exams.  1Z0-051 is not the worst (so far in my experience, the title goes to 1Z0 - 144).  However, because it is a review unproctored, Oracle University had to ensure that the period was quite short so that it wouldn't be feasible for someone searching for the answer to each question.  John's suggestion is reasonable, although I always recommend that when 'jump' the questions you have always put in your best guess, mark it and then move on to the next.  This way if you don't have the time to come back, there is at least a chance that you got it is correct.  I have not read the technical article by John, but here is one that I created a few months ago who was published in GoCertify.  The latest three tips are most relevant here.

  Oracle certification: 10 tips for any exam. GoCertify

  However, your note, you indicate that most of the questions took too long.  Unfortunately, it's just a matter of familiarity with SQL.  Someone who can read SQL, but don't have a lot of experience with it may take three minutes answering a given question, while a person who has worked with Oracle SQL for years he would complete in one.  There is no cure for this except practicing writing queries until you are more comfortable with it.  You can also consult the research resources that I have collected on my site for this review.    They are all safe certification and most are free.  In particular, it has links to a number of videos on YouTube of Oracle SQL intro courses.

  A suggestion I can do in trying to choose the correct answer from a list of similar SQL statements won't get one that fits the departure but rather identify those clearly wrong.  Usually there will be at least one or two with an obvious flaw - the wrong number or the order of the columns in the SELECT clause - an invalid comparison in the WHERE clause, etc.  I'll look through them and quickly eliminate these review before those remaining

• Could I take 1Z0-051 and 1Z0-047 together?

  Hi, I currently intend to take an Oracle PL/SQL Developer Certified Associate. Initially, I intend to take the path of 1Z0 - 047 + 1Z0-144, that leads to this certification, because the exam 1Z0-047 points also to an another cert (cert Oracle SQL Expert). So if I take this path, I'd end up with two certifications (cert Expert Oracle SQL and PL/SQL Developer Certified Associate)
  
  However, people keep telling me that 1Z0-047 is very hard, saying that 1Z0 - 051 is a lot easier if I want to guarantee a PL/SQL Developer Certified Associate.
  
  So, is it possible that I take all three exams (1Z0-047, 1Z0-051 and 1Z0-144)? I think that takes 1Z0 - 051 as a kind of 'practice' because it is an online exam and the scope of the review seems easy for me. I also have some budgets for me so I don't mind spend a little more money to the Oracle exams.
  
  I wonder if both of them (051, 047) are mutually exclusive in the policy review or something.

  So, is it possible that I take all three exams (1Z0-047, 1Z0-051 and 1Z0-144)?

  Yes, you can take both 1Z0-051 and 1Z0-047. In fact, I highly recommend taking 1Z0-051 before 1Z0-047. You heard correctly, 047 is a much more difficult test and requires a much higher level of experience or SQL knowledge. If you look at the subjects of study for the two trials, you will see that 1Z0 - 047 includes essentially all the 1Z0-051 exam topics and has an another 30 more topics. Study for 1Z0 - 051 is, in itself, the scrutiny of experts preparation. Discuss the two reviews in an article here:

• Problem with subqueries (1Z0-051)

  Hello, first of all sorry if this post belongs here.

  I am a student 1Z0-051 and I have a problem trying to understand why an exercise done my own does not work.

  In the press review of Oracle for 1Z0 - 051 on page 369, there is an exercise that says:

  How determine you which employees would have a manager who works for a Department based in the United Kingdom?

  The example is the following (using the HR database):

  Select first_name, last_name from employee

  where manager_id in

  (select employee_id in employees where department_id in)

  (select department_id from Department where location_id in)

  (select location_id from places where country_id = 'Ru')))

  order by name

  I tried to do it by myself and I wrote this query

  Select first_name, last_name from employee

  where manager_id in

  (select distinct (manager_id) employees where department_id in)

  (select department_id from Department where location_id in)

  (select location_id from places where country_id = 'Ru')))

  order by name

  The difference is in line 3, can someone explain to me why does not this way?

  Thank you very much!!

  Kind regards.

  We will try to put it in English.

  First query is:
  Select employees whose managers are employed in a service based in the United Kingdom.

  Second query is:
  Select employees whose managers are responsible for the employees in a service based in the United Kingdom.

  So for employees:
  Alice is at Headquarters.
  Bob is in UK Finance. It is managed by Alice.
  Chris is in UK Finance. It is managed by Bob.
  Diana is in us logistics. It is managed by Alice.

  First query selects:
  No Alice. It is not managed.
  No Bob. His manager is Alice, an employee's headquarters.
  Chris. His manager is Bob, an employee in the UK Finance.
  No Diana. Its Director is Alice, an employee's headquarters.
   
  Second query selects:
  No Alice. It is not managed.
  Bob. His manager Alice manages Bob, an employee in the UK Finance.
  Chris. His managers Bob manager Chris, an employee in the UK Finance.
  Diana. His manager Alice manages Bob, an employee in the UK Finance.

• Questions about Chapter 2 in Oracle DB 10g: SQL Fundamentals, II

  Hello
  
  first of all, I'm happy to be a member of your forum. I joined a beginner Oracle courses: introduction to SQL. I am facing some problems understanding some of the concepts in Chapter 2 of Oracle Database 10 g: SQL Fundamentals II text book. I got about 15 questions. However, I will only ask two questions initially. Since I am a newbie, please respond in a simplistic form. Excuse me if you see any grammatical errors.
  
  Remove a column can take some time if the column contains a large number of values. In this case, it may be better to put it's unused and drop when the number of users of the system is less to avoid the long locks.
  
  Issues related to the:
  
  "When the number of users of the system is less to avoid long locks."
  
  1. can you explain it to me please? less than before? less than? What happens if users continued to increase over the years! then this 'less' can occur until society not collapse!
  
  2. Why do we need to use unused columns? When to use unused columns?

  user11164565 wrote:
  "Drop column command will do table in exclusive mode lock, thus making it unavailable for others."

  Good explanation. For how long remains of this lock mode?

  The locks are kept as long as the transaction is not completed.

  This book is trying to say, but who use the unused clause to an unused column. It would eliminate the possibility of too many locks on the table, and later when you've got less users connected, you can delete the column as well.

• That means 1z0-117 oracle 11g sql tuning now say it includes v12 addition v11

  Hello

  I did the 1z0-117 sql tuning review once.

  Not too far away.

  I studied under and turned off for a while.

  I anticipate taking in 1 month.

  However, I just noticed that the oracle site says 1z0-117 also said that v12 is also included for consideration:

  Oracle 11g sql tuning.

  It makes no sense at all.

  Roger

  However, I just noticed that the oracle site says 1z0-117 also said that v12 is also included for consideration:

  Oracle 11g sql tuning.

  Unless you are looking for something I'm not, what actually is the 1Z0-117 page says: "validated against: review has been validated against Oracle Database 11g Release 2 version 11.2.0.1.0 and database Oracle 12 c 12.1.0.1.0"

  What they actually mean by it is that someone went through all the issues and and asked the question "is still a relevant issue for the release of 12 c to Oracle?'." "  If they find issues that are not valid because of an update/change, then the question will be removed from review (or changed) so that someone who has used 12 c but not 11 g will not at a disadvantage.

  This is * No * means that Oracle has added questions to the review of the capabilities that were introduced in version 12 c.
