The Case for an Updated SQL Expert Exam

There have been a couple of discussions in this space about the shortcomings of the current SQL Expert exam.  I decided to write something of an open letter to OU about the concept of creating an updated version for the 12c release of Oracle:
The Case for an Updated Oracle SQL Expert Exam - Certification Magazine
So what do you think -- what advanced SQL topics did I miss that would make a good topic for an improved version of the exam?

That does touch on a fundamental issue of certification: Does it realistically reflect work capability?  Many people over the years have just stated a categorical "no."  I wouldn't go that far, but I would say that for any particular job, it takes weeks or months to really evaluate them.  Some people when saying how they interview candidates state they would reject anyone who would just go google something new (I think that is a silly way to judge and am glad to see you google too IRL).  I know with analytics, I use them so rarely I have to basically re-learn them each time.  But there's nothing wrong with that, and subsequent "re-learns" are more rapid, and asktom (among others) is invaluable.  I would do the same thing for an exam - learn them long enough to pass the exam.  There's just too large of a knowledge space to make details of sql syntax a deal-breaker.  If you are using something every day, you remember the details.  The logical problem is assuming because someone is not using it every day now they haven't in the past or won't in the future.
In the past I've mentioned I think the value of certification for me lies in exposure to things I don't use.  A problem that goes along with that is if you don't use it soon after learning it, you might well have not learned it.  There are some courses I've taken that could be described as drinking the kool-aid - features that Oracle pushes that don't apply as generally as marketing or the developers of seed databases would like us to believe.  You never know what new features will be used and how and when.  Oracle doesn't always know, for that matter.

    ThanksIn terms of certification pre-reqs for DBA and PL/SQL OCA's you have an 1z0-147 which is one of the certification exams that satisfy that requirement.
    Afer passing 1z0-047 you need to consider whether you should take a developer track or DBA track
    From your posts you seem to consider 10g DBA OCA .... 11g DBA OCA would be better but if going down the DBA route your eventual goal should be DBA OCP ..... and that requires mandatory training and your may need to factor that in ... sometimes people may find workforce 10g DBA training is the more accessable to themselves.
    As for the books, both the Sybex and Oracle Press exam focused books have their advantages and disadvantages and faults. Oracle Documentation remains the authorative source.

  • Im trying to install a new application on my mac but it keeps on coming up with 'The volume of this disk does not meet the requirements for this update' any ideas how to solve this?

    I have recently fully updated my mac to 10.8.2 and i am trying to install a small facebook application but every time i come to chose the disk it says ' OS X facebook developer preview can not be installed on this disk. This volume of this disk does not meet the requirements for this update' any ideas on how to get round this?
    thanks

    That may be the new Mountain Lion "sandbox" protective software kicking in, possibly, because ML "thinks" that App doesn't meet ML's new strict security requirements.   A common phenomena.  If you feel the 3rd party App is really OK, you can override this feature and install the new App by holding down the Command key when you click to install the new App.  That's one possibility for the error message appearing.  If not, another possibility is that that Developer Preview software package requires some previous piece of software be installed prior to downloading this Preview.  You would have to check the Facebbok websiste's Developer Forums for help if this is the case.
    Hope this helps

  • I'm trying to change my phone case, i have the bumper that screws in if i goto the apple store will they unscrew the case for me?

    I have the bumper case that screws in so it doesn't fall apart, but i want to take it off. Will the apple store unscrew the case for me? or would i have to go to At&T to have them screw it off?

    Hey,
    I can confirm what xtremecaron has said, Apple will defo not remove the bumper for you. Best bet is to try different screwdrivers.

  • HT3255 Do the cases for the Macbook 13.3' air 2011 model fit the Macbook 13.3' air 2008 model?

    I recently purchased a MacBook Air 13.3' late 2008 model. I am looking for a case. Do the cases for the 2011 still fit the 2008 model?

    Generally speaking yes, but check the manufacturer's website to be sure.

  • 10.5.7 This volume does not meet the requirements for this update.

    First, 10.5.7 is not showing up in software update. I downloaded both the delta and combo 10.5.7 updates and they both give me "This volume does not meet the requirements for this update." I've done all the requisite stuff, permissions, volume check, reset PRAM, etc. I've downloaded the updates several times, and they worked on my 2008 iMac and 2007 Macbook Pro, so I know they work. I've searched and searched and can't find a resolution. It's as if there is some signature written to my boot volume that is preventing this update. Applecare was of no help either. Any ideas?

    Hi! Im new to this forum and i really dont know if this is the right place for me to say this but i really need some help!

    Hello
    More information would be useful, for example which Mac OS are you running.
    On the left menu item  About this Mac provides useful information.
    Also did you use Software Update to determine the update?
    Using Software Update can ensure you download and install the correct package for your particular Mac and OS version.

  • OS X 10.8.1 update cannot be installed on this disk. This volume does not meet the requirements for this update.

    HI
    I had installed mountain lion on my MBP 13" early 2012, but it has lots of issue, when i tryed to up date to 10.8.1 it shows the error "OS X update cannot be installed on this disk. This volume does not meet the requirements for this update"
    if i run the software update nothis is showing, current os version is 10.8

    This did not work for me.
    Note, that at one point the Apple developer knew exactly what the problem was and decided not to let us know. If we were tole what the problem was we woud have an idea of how to proceed.
