Always i have doubt with ID_NULL
Hello people ,
Can you explain to me shortly about ID_NULL , i know it check if the value exist or not but i want to know in these two cases
IF not ID_NULL (GROUP_ID) then
IF ID_NULL (GROUP_ID) then
in case not id_null mean if it does not exist ???
Hi,
The main function is ID_NULL and if you use NOT ID_NULL means it will give a reverse value.
That means if an id exists, then ID_NULL will return FALSE and NOT ID_NULL will return TRUE.
Regards,
Manu.
If my response or the response of another was helpful or Correct, please mark it accordingly

i have to import user dump file in the particular username i created in the tablespace ..
in os level i have just specify imp
and then prompt ask me username and i have specified the username and password i created in the tablespace ...but it shows invalid username..
anyone plz tell me how to import in the particular username ...user628136, as dbmsdirect.com had replied to you previously... this problem was because you were not connecting to the correct db.
in this case you specified the service name "rolta" and it connected successfully. So what error you were actually getting was quite right as the particular user "imeco" would not be existing to the database to which it was directly connecting.
I would recommend you that you can always check the ORACLE_SID before login into oracle.
echo $ORACLE_SID
if it points to the correct one then you shall not be facing this problem

I have always paid for apps with a credit card and now need to use an app store card but I can't get past the point where it keeps wanting my credit card updated. And can't used the app card number. Any advice???
I do NOT like using my credit card if I don't have to, and I went out of my way to go buy an Apple gift card, which I successfully redeemed into my Apple account. However, when I use the Apple "Cards" app, it will not let me use anything other than my credit card. I tried purchasing a card, hopefulling it would come out of my Apple store balance, but no such luck -- it came out of my credit card.
Apple is becoming more like Microsoft every day. -
we have always shared our music on one laptop but since I've had my iphone I've had my own user id. All of the music I downloaded was lost when I updated my iphone software and I have only been able to restore the music I have bought with my own id. However I've managed to import all of our itunes library to my new laptop but I cannot get it to synch with my iphone. How do I get it to download onto my iphone, I've gone from 865 songs to 74!

I always have trouble with my mailbox. It is always asking for my passwords but everything has been verified. How can I get it to stop doing it and start working????
There is only one thing that happens -- the Server does not respond.
Your mac concludes that you must have entered the wrong password. That may happen once, but then other issues become more likely, and it keeps asking for a new password.
Sometimes the Server is down for maintenance. Sometimes something is configured wrong. Some services do this on purpose to get you to use WebMail (pick up your Mail with your Browser) so they can show you some ads. -

when i click on the Firefox icon i want always to have to sign in with my proxy username and password.. i want more privacy in using Firefox in general.. is that possible? thanks
If you use extensions (Tools > Add-ons > Extensions) like <i>Adblock Plus</i> or <i>NoScript</i> or <i>Flash Block</i> that can block content then make sure that such extensions aren't blocking content.
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do not click the Reset button on the Safe mode start window or otherwise make changes.
*https://support.mozilla.org/kb/Safe+Mode
You can use one of these to start Firefox in <u>Safe mode</u>:
*On Windows, hold down the Shift key while starting Firefox with a double-click on the Firefox desktop shortcut
*On Mac, hold down the Options key while starting Firefox
*Help > Restart with Add-ons Disabled
If it works in Firefox Safe-mode then disable all extensions (Tools > Add-ons > Extensions) and then try to find which is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

I just updated to iTunes 11. This version will not allow me to change info on any songs. Have always use "command i" with previous versions. Anyone else experiencing this problem? A solution?
Hey! I had the same problem you did just today when I was trying to get my second iPhone to sync. What you need to do with music or anything extra that you doing you have to creat a second playlist or picture or anything that you would like to use, so that you can add to the second device that you are going to be using. I am not sure if that will help but it helped me out a lot!! Good luck!

if i made an appt. with Apple, and i asked them if i could switch my black Iphone 5 to a white Iphone 5, because i always have trouble with black Iphones, would they let me?
i've had black iphones in the past, and the same thing always gets messed up, the network, i will not have service what-so ever, and when my mother's iphone will be right next to me and she will have full service. Also the lock screen button/power button broke on both of my black iphones as well. i was just wondering if they would consider. Does apple have an email i could contact?

macbook pro 2010 with 2.4 Ghz intel core 2 duo can i upgrade to mountaion lion ,i have doubts that it becomes very slow
Welcome to the Support Commuities. See under Supported Models here:
OS X Mountain Lion Technical Specifications
...Although your MacBook Pro is supported, it may be advisable to wait until OS X 10.8.1 or 10.8.2 in order to avoid the possibility that your Mac slows down due to bugs in 10.8.0. -
I can't download the Adobe Premiere Elements 13. Akamai Download pop up only the download window but downloading do not start. Alternate download Method will start but downloading will stopped always after 655 Megabytes. I have tried with different browsers, fire wall and virus protection off and also to download the trial of Adobe Premiere Elements 13 but result is every time same.
if you follow all 7 steps you can directly download a trial here: http://prodesigntools.com/photoshop-elements-13-direct-download-links-premiere.html
and activate with your serial number.
if you have a problem starting the download, you didn't follow all 7 steps, or your browser does not accept cookies.
the most common problem is caused by failing to meticulously follow steps 1,2 and/or 3 (which adds a cookie to your system enabling you to download the correct version from adobe.com).
failure to obtain that cookie results in an error page being displayed after clicking a link on prodesigntools.com or initiates the download of an incorrect (eg, current) version. -

i have problem with my I PHONE 4S Always its time out then i must restart my I phone please any help about this case ??
Hello Pllumb,
It sounds like you are unable to turn on Wi-Fi because the option is grayed out in Settings. Use these steps from the following article named:
iOS: Wi-Fi settings grayed out or dim
http://support.apple.com/kb/ts1559
Restart your iOS device.
Make sure that airplane mode is off by tapping Settings > Airplane Mode.
Reset the network settings by tapping Settings > General > Reset > Reset Network Settings.
This will reset all network settings, including Bluetooth pairing records, Wi-Fi passwords, VPN, and APN settings.
Make sure that your device is using the latest software. To do so, connect your device to your computer and check for updates in iTunes.
If you still can't turn Wi-Fi on, please contact Apple for support and service options. If you can turn Wi-Fi on but are experiencing other issues with Wi-Fi, please see these steps.
Thank you for using Apple Support Communities.
All the very best,

I have always synced my iPhone with my PC, what will happen if I sync my iPhone with my new Macbook Air?
I am hoping to switch from being dependent solely on my PC to rarely using it and having freedom to use either more Mac/iPhone and less PC, but I have my MSOffice software on the PC .
I want to sync my iPhone and not lose anything and have a faster experience.Check out this user tip from TuringTest:
