Yes, he does.  As Jonathan, Oracle rewrites internal count (1) by count (*) in recent versions.

In general, I suggest using count (*), since that's what Oracle prefer of course (it rewrites the other requests to make a count (*) if possible).

  • What is the difference between Count (*) and Count (1)?

    Hello

    can you please what is the difference between Count (*) and Count (1)?

    I saw that Count (*), Count (1), Count (2)... etc return values from a table. Is there an exact difference between them?

    Have you read the forum space FAQ? I'm sure that you don't have because it is answered there.

    It is also answered via Google.

    The short answer is: there is no difference, unless you use count (1), count (2), etc. instead of count (*) it makes you look like an amateur.

    COUNT (1)

    See that both give the same time

    Do you really think the 100th's of a second it takes 6 rows from counting will truly representative of the difference it takes actually?

    Such a small data set cannot possibly show no difference to these larger units of time (in the calculation of terms where we have millions of instructions per second in lieu)

    As the link to the FAQ provided in the response of Anton (first response on this thread) Watch, count (1) and count (*) are essentially the same, except that count (1) actually get re-written by the query re - write the step of the optimization to make it count (*).

    Generally 'count (*)' makes more sense language, because it reads like "count" while "count (1)" reads as "count we ', which does not have as much good sense when you actually count all.

  • Difference between flow and stolen

    Hello
    can you please tell me difference between flow and stolen

    Thank you
    Nirmal

    See: http://docs.oracle.com/cd/B31017_01/integrate.1013/b28981/parallel.htm

    flow will be to use a pre-defined () amount of branches, with flight you can do the amount of dynamic branches

    So let's say we have

    getUserDetails
    getAddressDetails

    now, you can use streams, create 2 branches and make the call to both methods in each branch.

    Let's say that you receive a list of customers in your service interface. Now, you can loop through with-foreach each customer and sequential not logic like Getcustomerdetails in the loop, or... .you create a flight and N is the number of clients in the list.

    After that, you will get N parallel branches that will make Getcustomerdetails (instead of the other sequential loop)

    This fly is the dynamic Variant that will create N branches according to the Counter field you base your expression on

  • Difference between getRowCount() and getFetchRowCount()

    Hello


    What is the difference between getRowCount() and getFetchRowCount()?
    and where to use this method.

    Thank you and best regards,
    Jean Blaise

    Jean Blaise,

    getRowCount() causes the whole view defined subject line must be extracted from intermediate level.

    getFetchRowCount:-This tells us the number of lines that have been recovered in all lines, and not pull additional lines in some of the other methods 'get count' will love.

    That said, if you have a table with a default row area of say 10 lines per page, then fetchrowcount will display 10 at a time and getrowcoutn will show whole row in VO.

    int fetchedRowCount = vo.getFetchedRowCount (); Print the number of line exposed in a table at the same time

    vo.getRowCount (print as many rows in VO)

    Thank you

  • Difference between Oracle and Prometric test center?

    What is the difference between Oracle and Prometric Testing Center?

    Pass the examination in a CTA is exactly the same as the exam at Prometric. The review is exactly the same and it's exactly the same thing. The only difference is the location where the examination is taken, so I believe that over-the-counter medications have set schedules to offer tests, take exams at Prometric can give you a little more freedom to your schedule.

    Answers to the questions:
    can you any valid CTA agent/Center in kolkata? Then I will be very grateful
    -You should go to www.oracle.com/education and you can search on the keywords "certification" or "OTC test"
    - Or you can call your local representative of OU. You can find your local numbers to http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=225
    -Please note that if you are in North America, your search for OTC drugs will not return any results. Over-the-counter medications are not available in North America.

    If someone got 051 OTC and 144 of a promeric / pearson since it granted as OCA?
    Yes

    List there is the offer of TBT that are testing to the general public?

    Is there a TBT in countries other than the United States., UK, Japan, Germany?
    -There is no over-the-counter drugs to the United States.
    -There are also over-the-counter drugs in Asia-Pacific

    CTA can be only in branches of Oracle or OAEP?
    -I don't know where are all over-the-counter medications. It is preferable to refer these questions to a representative of the ORGANIZATION unit. They will be better able to help.

    Reloading Web pages and cache bypass aims to obtain a new copy of perhaps obsolete or damaged files currently stored in the disk cache.
    You can do it like the first attempt if a normal charging does not seem to provide a version of a Web site or if you are having problems with a Web site otherwise.

    We usually have advice that if you have questions:

    Reload Web pages and ignore the cache to refresh potentially stale or corrupt.

    • Hold down the SHIFT key and click the Reload button
    • Press 'Ctrl + F5' or 'Ctrl + Shift + R' (Windows, Linux)
    • Press 'Command + shift + R' (Mac)

    Clear the cache and delete cookies only from Web sites that cause problems.
    "Clear the Cache":

  • Qosmio X - 70A - difference between nVidia and driver Toshiba GPU

    Is there a difference between nvidia and one packed by toshiba display driver?
    I'm using the Toshiba but Geforce experience gives me a headache with warnings about a newer driver and toshiba does not appear to provide a.

    Of course there is a difference between the GPU nVidia drivers (or drivers provided by manufacturers of graphics cards) and the drivers provided by Toshiba.

    The Toshiba driver page GPU drivers are changed and made for the mobile use.
    Each laptop model supports various components (CPU, cooling, modules, etc.) and different design. That is why the heat dissipation is always different.

    The GPU driver provided by Toshiba supports a kind of GPU overheating protection and protects the graphics chip of the damage. This means that the GPU performance are controlled by the driver and in case the internal temperature would rise to critical level, it would decrease the performance of the GPU. Also the laptop stops automatically if the temperature is too high.
