clustered index and non-clustered indexes

Hi ihave read on index qqustion

in SQL Server, table has 1 clustered index and 280 (average) no clustered index.
SqlServer hold a clustered index and the data on the same location. index if cluster command firm data
but sqlserver hold index non-clustered on another file and do not directly order data.
oracle index how does this? for example, I have 3 indexes on the table. how they work? is oracle this clustered index and indexes not clustrered?

Oracle has no cluster & nonclustered indexes.
Oracle has Btree, bitmap, text, index basis function

  • Downloaded my site and none of the pictures show

    I just uploaded my site to my hosting provider, and none of the images are appearing.

    Hi JSillesen,

    When the web site is exported for the first time the image file is created with a small 'i '. But when you export to a location where the folder already exists, then name in has not changed. This could be what has happened with you. Try to export the web site in a new folder and check if it was created with a capital 'I' or an 'i' small.

    Kind regards

  • I have followed closely at least six different sets of instructions to make this transfer, and none of them worked.

    At the same time, I made five new ringtones of the song of the birds and their synchronized successfully to my iPhone. Now, I did one more and I cannot get transfers, although it see the upward in my iTunes library on my iMac. It's less than 30 seconds and he appears as the correct type (ringtone). I have followed closely at least six different sets of instructions to make this transfer, and none of them worked. I am running the latest operating system, the most recent iOs and the most updated iTunes on both systems. Help, please.

    < re-titled by host >

    Hello saelon,.

    Looks like you have problems of synchronization a ringtone from iTunes on your iPhone. I know how fun it can be to create and use custom ringtones, so I can understand why you would reach for help when he's not working for you.

    To find out how to properly synchronize your ringtones to your iPhone, see the article: syncing your iPhone, iPad or iPod touch with iTunes on your computer via a USB - Apple Support

    If you still have problems of synchronization of this tone, it could be that the tone is not appear in the iTunes ringtones section and/or is not selected to synchronize. This applies specifically in numbers 4 and 5 of the article above the synchronization.

    If your custom ringtones do not appear in the "Tones" section in iTunes, it is possible that they are not in the correct format. If you do not already have, the program that we recommend for creating ringtones for your iPhone is GarageBand, it's available for iOS and Mac OS X. check the resources below for more information on this:

    GarageBand 11: Create an iPhone ringtone

    GarageBand for iOS

    GarageBand for Mac OS X

  • Tecra A8 downgraded XP and none of the Toshiba Utilities works

    Hi all

    I just got a new Tecra A8 - it is downgraded to XP, and none of the Toshiba Utilities work (energy saving function keeys, keyboard shortcuts, etc.). When I try to reinstall - there is always an error message (missing dll or sth similar) - I tried to update the bios - couldn't - once again a missing file!

    any ideas how to solve this problem? at least the fn keys (fn key works - I see a light come on when I press - not the functions well!)

    your help, I much appreciated!

    see you soon,

    Dimitris

    Hi Dimitris

    May I ask you what Tecra A8?
    I visited the Toshiba driver page and it seems that Toshiba provide XP drivers for two different units A8 PTA83Eand PTA82E.

    You should be 100% sure that you are using the correct drivers!
    In addition, Toshiba released the Installation Instructions of the document on the page and to my knowledge it s necessary and important to follow this line of installation guide. The proper installation order is necessary!

    So take care and check again

  • Courses and non-traversal calls

    Hello

    Can someone explain in simple terms what are courses and non-traversal calls?, what is the difference? And also the VCS control below must traversal licenses?

    CTI-VCS-CONTRL-K9

    Control of VCS

    Thanks in advance.

    If you have two endpoint C-series (i.e. CTS-SX20) both recorded on VCS control and also capable of reaching out directly between them (a routing), then in general the call will address as non-traversal call Endpoint, so no license courses will be necessary.

    However if these Endpoint calling each other, but using different protocol (i.e. an end point registered in VCS control only with H323 and other endpoint registered on the CV with SIP), or different IP version (that is to say one with IPv6 and other with IPv4 registration), then control VCS remain media routing in order to manage such scenario of interoperability which will require licensed traversal appeal.

  • Download touch and non-touch application with the same name

    HII I'm doing a new version of an application

    in the new version of the application, I have two separate release touch and non touch.

    so create us the same name of the app and app-world as a separate product with a different version

    and download sound on 22 Dec 2012 but until the pending status

    so exactly what I do if blackberry approvue my request

    When I send an email to app world support rereading as 'is there a reason? why you create the same application again  You can't have two applications in the portal of the same name. »

    Thanks again in advance for proofreading

    I would look to create the same application in charge touch and non touch at the same time.  You can do if your application supports OS 4.7 and later only.

    If you really need to do two different builds, then add the two builds in separate bundles to the same app on App World and use the selection of the device to make sure that your touchscreen package is only for touch devices to screen and vice versa.

  • A project which supports the devices to screen both touch and non touch screen.

    Our team works at the request of BB, which is oriented to a wide range of supported devices. It should support devices with OS version 4.2 - 5.0. We decided to use the v4.2 OS APIs. Then our application would be supported by all devices. It was a successful until recent times. Problems arose when we started to use navigationMovement() function to handle events of movement. This function works very well on devices with a trackball and it does not work on touch screens. On touchscreens, we should replace touchEvent() function.

    When we added touchEvent function to our project, then the project could not be started on devices with OS< v4.7="" (error="" starting="" application:="" class="" 'net.rim.device.api.ui.touchevent'="" not="" found).="" so="" i="" think="" we="" should="" split="" our="" project="" in="" two="" branches:="" the="" first="" will="" support ="" touch="" screens="" and="" the="" second="" one="" will="" not.="" there="" will="" be="" two="" shortcomings="" in="" this="">

    1. we must ensure on corrections in the two projects. It can happen that one branch has been updated and the other is not observed (has been forgotten for example).

    2 instead of this a binary, we will have two binary. But it is easier to have a binary that works on all desired platforms.

    So please give me an advice how should we update our project to make it work on touch and non-touch screen devices.

    Software development we use: JDE 4.2 and 4.7 JDE.

    you could build a library for the base classes 4.7 project and use the dynamicy for them class (class.forname) loading. or use the preprocessor, but then you would still have 2 versions
