"You cannot overload stand-alone subprograms.

Hello
So, I see it everywhere, but of course, this means something different from what I understand it means, for example
create or replace function ff return integer is 
begin
    return 0;
end;
/
show errors

create or replace function ff(x in number) return integer is 
begin
    return x;
end;
/
show errors
Output:
SCOTT@ORCL> @C:\Users\J\Documents\SQL\test13.sql

Function created.

No errors.

Function created.

No errors.
What am misunderstanding here? How is functions ff not stand-alone subprogrammes?

Thank you
Jason

Hi Jason.

You use create or REPLACE, so the other replaces one, that a function is created.

Please read this: http://docs.oracle.com/cd/B10501_01/appdev.920/a96624/09_packs.htm#4937

Kind regards.

    Hello

    No, you cannot overload a stand-alone function. Overloading only works in packaging.

    How do you run a stand-alone program after its installation on the CD - RW disc

    Programs are not * install * to a CDRW at least that the CDRW is seen as a disc using the writing software to package such as DirectCD (Roxio) or OnCD (Nero). A disk used with writing software by packages cannot be used on any PC.

    Files are copied to a CD - RW for storage and retrieval. If the program installs, it install in general in C:\Program Files or similar and often drop files into \Windows and other places, too.

  • You can purchase stand-alone bridge?

    At work, we mark our files in Bridge with metadata, such as copyright information. All this is well and good, Windows does not display a lot of information added to the files, so that our clients should also bridge to see.

    Not wanting to buy a suite, is Photoshop or any accompanying bridge, possible to get just bridge on its own for customers to purchase to view the data? Or is there another program that still may be free and well known for its customers to use?

    Thank you

    -Ricky

    No, bridge must have some app from Adobe installed to work.

  • Can you distribute a stand-alone single edition folio app?

    Currently I use the viewer Adobe content to distribute Folio for a couple of clients.  A customer want only edition folio created apps, but don't like the idea of them being in iTunes.  Is it possible with distribute (publish) a single folio app outside of iTunes edition?  In the same way you can create any type of iPad application and create an installable package without going through iTunes...

    Thanks for any help,

    Greg B

    The only way to do this is to create a developer version of the app but it

    will expire and will be limited to 100 UDIDs.

    In short, it will not happen without enterprise-level accounts

    with Apple and Adobe and is still subject to restrictions of license defined

    by Apple for the distribution of the app.

  • 401 error after you deploy for stand-alone WLS

    I use JDev 12.1.3 on Windows 7 Pro

    My app has been migrated to 10g, 11 g to 12 c. He had a guarantee of manufacture which has been replaced by ADF security.

    I have it on my integrated WLS but after deployment to standalone WLS I get 401 - error not allowed after connection through OAM.

    I checked the server logs and don't see any error. The sys admin looks at some other newspapers but nothing concrete yet.

    The app has 26 roles of the company and my login has 5 assigned roles. Some business roles have been defined as Active Directory groups. I tried to check if the roles are case sensitive, but who has not found in textbooks again. Ad groups do not match the case of the roles defined in jazn-"Data.xml".

    Any suggestions on what and where to look is greatly appreciated.

    One suggestion is to remove all business roles and try to make it work with a single role. I intend to try this.

    Thanks in advance!

    Dave

    We found that the question. Business roles are case-sensitive. Windows administrator define groups of ads as of breaks. Jazn-"Data.xml", I made the business roles are all uppercase. Evolution of business roles jazn-data to match fixed the issue ad groups.

  • Server R2 2012 crashing when you deploy the stand-alone host model.

    I encountered a problem with my server 2012 model deployment to a new independent host that I built in my virtual data center.

    Specification of the server:

    HP DL380 g8 linking the latest PSP firmware updates

    Local storage

    ESXi 5.5 U2 may 2015 HP build

    Card 8 GB SD for esxi 1.9 local TB SAS storage

    HP P420i

    Whenever I have move R2 server in 2012 to that Server Manager host down and other questions are noticed.

    Another noticed is characters and text on the virtual machine begins to blurr from the console.

    If I power off the virtual computer and move it to a server in my group I have no problem. Both servers are running the same version of 5.5U2

    Has anyone seen this problem before or suggestions?

    The result of more tweaks and troubleshooting exposed a faulty processor.

  • How do you improve stand alone LR5 LR6/cc?

    Hello

    I've been running a stand-alone copy of the LR5 on a Mac which also has Photoshop, Muse, Illustrator (etc. etc. etc.) DCI

    Installation of LR CC should be easy enough, but it will modernize the existing version of the LR5, which I want to do?

    If it's a secondary copy, I can move in parameter files? I have several years worth of customizations, I want to keep...

    Thank you very much.

    Hi Frax,

    First of all, all these customization and settings may already be stored in your Lightroom Catalog. Thus, you don't need to worry about the upgrade of their. As soon as you launch Lr 6/CC, it will ask you to update your catalog and transfer all the settings.

    Now talking about the upgrade of Lr 5 sucks, if you have the stand-alone Lr 5 copy, you can buy the new Lr 6 products. Otherwise, if you have the Cloud of Lr 5 version, then just run CC desktop application and install Lr CC 2015 in new apps section.

    See you soon!

  • Is it possible to buy Lightroom as a stand-alone without the cloud?

    I really don't want to download anything for the "cloud." no pictures, no documents not a BLT half-eaten.  Is it possible to buy Adobe Lightroom as a stand-alone product without the adhesion of cloud?  If so, how?  I searched and could not find a stand-alone option.

    Hi Manon,.

    Yes, you can purchase stand-alone 6 Lightroom available here: Software & Services

    And by buying the subscription of cloud creative, photos, documents or anything that does not get uploaded to the cloud by default.

    You would have that full access if you want to store anything online or not.

    Lightroom would be installed locally on your machine and everything, including the Lightroom Catalog, photos and everything will remain on your machine and not on the clouds.

    Here is the difference that you can see: compare Lightroom CC vs versions 5 & 6 | History of Adobe Photoshop Lightroom CC

  • Stand-alone table in the repository

    Hello world!!

    I'm creating a repository with Administration Oracle BI tool. I have a problem with a table which does not join another repository, the description of the error is:

    Why is not possible to have a stand-alone table in a repository?

    Thanks in advance!
    Jorge.

    You must have at least one other table attached to it... Since it is the '' possible more little star. '' If you need a stand-alone table, you create an alias of the table in the physical layer, bring together both by their PKey and then you're fine.

  • Want happens to a stand-alone license after you purchase/cancellation creative cloud?

    I have a stand-alone license of Lightroom 6 and I am now looking to buy a map of creative cloud. Because Lightroom is included in the CC plan, I guess that Lightroom will be updated via CC and is no longer my standalone license.

    But what happens if I cancel my CC plan in the future? I will be able to return to my stand-alone license?

    Do I need to uninstall the CC version and reinstall the stand-alone license?

    Thank you very much for your help!

    Hi e__p,

    I have a stand-alone license of Lightroom 6 and I am now looking to buy a map of creative cloud. Because Lightroom is included in the CC plan, I guess that Lightroom will be updated via CC and is no longer my standalone license.

    But what happens if I cancel my CC plan in the future? I will be able to return to my stand-alone license?

    Your Standalone with Lightroom version will not be affected if you cancel CC membership in the future.

    Lightroom CC and 6 Lightroom are produced almost similar but different licensing system.

    Do I need to uninstall the CC version and reinstall the stand-alone license?

    Just log out of Lightroom CCfrom help > logout

    Then reconnect, it should say your CC membership is expired/Invalid.Follow the instructions mentioned in How to convert a Lightroom CC 6 Lightroom trial to serialize Lightroom 6.

    Kind regards
