  I can do better than see you Matthew here resources:

  http://certmag.com/oracles-SQL-expert-exam-slated-facelift-Sept-15/

  You are already aware of the post of topics updated September 2014.  You should subjects newly introduced (and there is really only a handful) will not be in e.g. book of O'Hearn and you sick he had to study these and practice literature oracle; Quality of oracle articles; Oracle Learning Library etc.

  other topics that he probably come in two categories: features present in 11g, but was not present at the review.  And features introduced with 12 c.

  While the description reads review: this review has been validated against Oracle Database 10 g, Oracle Database 11 g, Oracle Database 11 g Release 2, and database Oracle 12 c Release 1, taking into account the characteristics of 12 c are tested this should now rad this review has been validated against Oracle Database Release 1 12 c. (Not 10g / 11g).

• Oracle SQL Expert review 2015

  Hello world

  Is there someone who take the "Oracle SQL Expert" review recently in 2015? I want to ask your views on review, you can share your opinion about the exams. In fact, I want to know how many Oracle 12 c features included review?

  Can you please share your experience?

  Thanks in advance

  You cannot use other experiences to predict what you'll see, because not everyone gets the same set of questions.  I don't have enough inside information to see how the questions are determined, but based on my experiences, I believe that tests each have a pool question about twice as many questions that the review is designed to mark and the specific questions that each person receives are selected at random.  If this is the case, the number of questions of 12 c receives a given person can vary considerably.

  That said, you can have a topic idea how many questions by themes is possible by comparing the number of subjects to the count of exam question.  There are 79 different topics on 1Z0 - 047 and review will have 75 questions. While this comes out less than one question per subject, 047 review is a bit unusual in that one question may require more knowledge of a subject.  For example a question involving a query that uses a subquery EXISTS and would cover both 'use the operators EXISTS and NOT EXISTS' and 'Write a row and several lines of subqueries' subjects.

  However, it is unlikely to see more than two questions on a given topic, and most will have only one question. With this, you can watch all the listed topics that concern you and come with a relatively precise range of issues you might see on them.

• 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.

• Certified Oracle SQL Expert Exam - 1Z0-047

  I plan on taking the exam 1Z0-047 and recently (in the last 3 weeks) bought the study guide / review of Kaplan for Oracle 11 g r2 for this test practice (or at least I thought it was up to and including Oracle 11 g r2).

  If I understand correctly what I read, it seems that questions for version 12 of the database are now included in this review.  There is apparently no separate examination that does not include the Oracle 12.  Is this correct, or can I still request a review for 11g r2?

  This is also true for PL/SQL and other exams (must study for any question 12 c)?

  Given that most of the developers I know is not yet up on 12 c, it seems that there should be at least an option of which version of the database you want to testify against.

  Everything / all thoughts are appreciated.

  Barry D.

  If I understand correctly what I read, it seems that the issues for version 12 of the database are now included in this review.  There is apparently no separate examination that does not include the Oracle 12.  Is this correct, or can I still request a review for 11g r2?

  I guess in what above, where you have "now", you want to say 'no '.

  No there is only one exam 1Z0-047.  The number of topics under review that are specific to Oracle 12 c is minimal.  I've updated my page on the contest of Expert SQL include articles on these topics, so you can prepare for them, even if the Kaplan materials do not yet cover them.

  Oracle Certification Preparation: Details of the examination and preparation for 1Z0 - 047 resources

  This is also true for PL/SQL and other exams (must study for any question 12 c)?

  The current reviews of PL/SQL (1Z0-144 and 1Z0-146) have not been updated to 12 c.  In my view, that the two have been validated against ut 12 c. which simply means that nothing they contain is wrong for 12 c - No 12 new c-specific features have been added.

• Help in to convert CASE to DECODE in 11g sql

  11 GR 2, Windows.
  
  Can someone help me rewrite under sql CASE statement to DECODE?
  

  SELECT INVOICE_ID,sum(TOTAL_EXCL_VAT),LEVEL2 as descr,
  sum(case when instr(LEVEL2,'Internet')>0 then SUM_QUANTITY else 0 end) as KB  --- >> Here
  from rator_cdr.INVOICE_DETAIL_LINE

  group by LEVEL2,INVOICE_ID;

  Thank you

  Why would you want to replace the much more expressive syntax of CASES with a DECODING?

  If you are really determined

  DECODE( instr( level2, 'Internet' ), 0, 0, sum_quantity )
  

  I would strongly prefer the option CASE, however.

  ORA-00205: error in the identification of control files, see log alerts for more information

  It's a symptom of an execution incomplete Installer, basically you have a database at startup. It's I think, anyway.

  Only suggestion is to make an uninstall, after all the uninstall the steps outlined in the Installation Guide for Windows, then try running Setup.

  With later versions of Windows, some things have need a session "run as Administrator". And that's it, as far as I know of the Windows operating system.

  See http://docs.oracle.com/cd/E17781_01/install.112/e18803/toc.htm#CIHDDHJD

  Hello, I need to configure SQL Trace to the instsnce level. I need capture query plans and bind values. I think I set SQL_TRACE = TRUE. It will capture all the info I need? Are the trace flags, that I can set as well at the level of the system?

  See my post on this topic:
  Re: SQL_TRACE helps newbie in oracle

  The command you're looking for is this one:

  ALTER SYSTEM SET EVENTS '10046 TRACE NAME CONTEXT FOREVER, LEVEL 12';
  

  Do not specify the scope. Note that you can use a logon trigger to create a trace for a specific user or application.

  The next question is to know how to read the file, see my post on this topic:

• JDeveloper does not support the SQL expert, cannot add query clause to view link

  For developers who can know:
  
  I use JDeveloper 10.1.3.4 and I have two tables, we're STUDENTS, the other is the PRICE, with a one-to-many relationship (a student may have several awards), and ID is the foreign key:
  

  STUDENTS
  ------------------------
  ID    NAME    DOB
  ------------------------
  9999  JOHN    01/02/1990
     |  
     |  
     |  
     |           AWARDS
     |           ------------------------
     |           ID      DESC      AMOUNT
     |           ------------------------
     ----------- 9999    PELL      500
                 9999    PERKINS   800
                 9999    LOAN      900

  In the application, when a student (9999, JOHN) connects, the information above is displayed. I need to add up all the awards for the student and to display not only the elements of price, but also the total amount of all awards. To do this, I created another object to view named TotalAwards in the object entity the price just to get the total amount. The SQL code of the VO's
  

  SELECT SUM(Awards.AMOUNT) AS TOTAL
  FROM AWARDS Awards

  Then, a link is created between the students and the TotalAwards, and use of the new link to the view is added to the application module. TotalAwards is now available in the data control palette to be drag-and - drop to pages.
  
  Problem occurs when the application is invoked. An error is caught before the application can begin. The error message indicates that "the ends or the link view do not specify an attribute.
  
  It seems that the TOTAL 'SUM (Awards.AMOUNT) AS TOTAL' is not recognized as an attribute. I have reviewed the query clause in the display link to see if it is there, such as:
  

           Attribute        Bind Variable
           ------------     --------------
           Students.ID      :Bind_Id
  
  
  WHEHE    :Bind_Id = Awards.ID

  There is no such clause in the query clause page. And I can not add a no more, because the page is grayed out and disabled. I think maybe it's for the same reason: TOTAL is not recognized as an attribute of the price.
  
  How to get around the problem? Or are there other ways to summarize the total amount and view it in the browser?
  
  Thank you very much for help!
