Is there any way I can avoid 2x FTS on that query
Hi,
I'm on 10.2.0.3 and got query which is doing 2x full table scan because of union all, can I use some equivalent to make that only 1x FTS ?

Hello
If it's the full scan that's expensive, then it may be worth using sub query factoring and do all of the aggregation in one hit(you're grouping on the same columns so there shouldn't be a problem there.
Just to note though, you don't need to use DISTINCT when you have group by.

When iOS 6.0 updating my iPhone and connecting my iPhone to iTunes the only option I have, is to restore my iPhone. But ufortunately, I did not back up my iPhone before the updating. Is there any way I can avoid the restoring process?
Once the Device is asking to be Restored with iTunes... it is too late to save anything...
To minimise loss... Connect to iTunes on the computer you Usually Sync with and Restore from the most recent Backup...

The situation: Whenever I go to use the address bar or the small search toolbar (which is set to google) in my window, the search engine used instead is "search.searchcompletion.com", which returns very shitty search results and is annoying.
The things I have tried to fix this:
First, I disabled and deleted all my add-ons, changed my homepage back to google and updated my search engine to google. Tested search bar, *still infected* RESULT: NEGATIVE
Second, I downloaded a anti-virus/anti-malware program called Malwarebytes. It did good, catching 28 virus's in various files, quarantining them, and deleting them. I tested the search bar, *still infected* RESULT: NEGATIVE
Third, I read about typing in "about:config" into the Firefox address bar and changing a few things, as explained <a href="http://deletemalware.blogspot.com/2011/09/remove-startsearch-and.html">here</a>. I tested the search bar, *still broken*. RESULT: NEGATIVE
Fourth, I read you can "manually delete the virus from your registery". I followed the instuctions carefully, deleting these strings: HKEY_CURRENT_USER\Software\Policies\Microsoft\Internet Explorer\Main “Start Page”
HKEY_CURRENT_USER\Software\Policies\Microsoft\InternetExplorer\Control Panel “HomePage”. Tested the search bar, *still infected* RESULT: NEGATIVE
Fifth, someone somewhere installed a special add on that blocked certain sites. Whatever I did it did not work, the site (search.searchcompletion.com) just lost it's formatting, but still did not let me search using google. RESULT: NEGATIVE
Fifth, I just uninstalled everything having to do with Firefox from my computer. I reinstalled it and tested the search bar and it worked!....
For 24 hours. When I turned on my computer today, the search.searchcompletion virus is back, and short of uninstalling Firefox, I do not know what to do.
I have no add-ons.
I have deleted temp internet files
I have virus protection
I have tried everything.
Help me.Plugins usually are installed externally to Firefox. However, you can disable them in Firefox so that Firefox does not use them.
SearchReset is supposed to automate the task of resetting certain preferences, but you still can edit them manually if necessary.
'''''Address Bar Search'''''
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the filter box, type or paste '''keyword''' and pause while the list is filtered
(3) Right-click '''keyword.URL''' and choose Reset. This should restore Google as the default for address bar search.
Does that work?
'''''Search Box'''''
Usually it works to choose your preferred search engine from the drop-down. To remove an unwanted search engine plugin, usually the Manage Search Engines... choice at the bottom of the drop-down takes care of it.
Do either of those work?
There might be another way to hijack that search box; I think some of the other frequent responders probably are more familiar with it than I am. -
Is there any way I can re-download an album that I purchased?
Because I recently purchased and "successfully" downloaded an album (Givers -- In Light) -- however after about 60 seconds in every song it skips to the next song. It won't let me listen to any of the full songs. This is very frustrating, and it may be due to the slowness of our internet speed at my work. I already clicked "My purchases" in the iTunes store, and searched for the specific album. But, the "download" link was grey and wouldn't let me download it. I also tried clicking the "store" tab in iTunes and checked for available downloads...it responded with there weren't any available for download. iTunes thinks that this was a successful download, when it was obviously not. Any ideas, tips, and suggestions would be greatly appreciated. Thanks.
Best,
JesseLog in to iTunes Store. Select Purchased from the Quick Links section in the right-hand side bar. Re-download.
You may have to delete the corrupted tracks first. -

To burn a DVD with iDVD from the latest version of iMovie, you have to export the movie using the Export button and select 480p as the size. Open iDVD and start a new project, then drag that exported movie file into the iDVD menu window, avoiding any drop zones you see. -
My desktop pc has died and I have not backup up I tunes for months. If I install I tunes onto my laptop is there a way I can avoid losing all my data since my last backup?
You should be able to:
Backup the device to the new windows installation
Transfer your purchases into a newly authorized library
Recover any other media using third party tools as suggested in this post from forum regular Zevoneer
Restore the device from the backup
This process should switch the association of the device to the new library, preserving the data and settings in your apps.
When you get it all fixed, make a backup!

I want to buy a new apple tv but it used hdmi cables and my house is only wired for analog. Is there any way I can use the apple tv on analog cables?
Welcome to the Apple Community.
It's do-able, but I don't think it's a great idea.
DVI
Some users with DVI have managed to get their TV's to work with DVI-HDMI cables. DVI carries no audio, so alternative connections need to be explored to enable audio. DVI doesn't necessarily support HDCP as well as other standards used by HDMI (which may or may not be an issue)
Analogue
There are hardware converters that will convert HDMI to various other types of output, however there are some issues with doing so that you should be aware of.
HDCP
HDCP compliant converters will not allow you to watch HDCP protected content such as that from the iTunes Store. Non compliant converters exist but we cannot discuss them under the Terms of Use for these communities.
Resolution and aspect ratio
I'm not aware of any converters that will scale the output from the Apple TV, any TV or projector which is used will need to be widescreen and support resolutions of 720p (Apple TV 2), 720p/1080p (Apple TV 3)

I just upgraded my MacBook from OS X 10.6.8 to Mountain Lion so that I could stream from my other devices (iPhone and iPad) to my MacBook. After making it through the upgrade process, I realized that I used the wrong email address for my iCloud username when starting up on the MacBook. My iPhone, iPad, and iTunes are under my Hotmail email address and I accidently used my Gmail email address for the MacBook. Is there any way I can merge these two icloud accounts together? I tried changing my account information to add the other email address, but wasn't allowed because another account was using the name (duh). If I can't merge them, how could I change the MacBook from the Gmail address to the Hotmail address so that all my devices are on the same icloud account? It'd be nice if I could keep the free 5GB of storage that comes with my purchase of the software, but I'd rather lose the storage than not be able to stream.
To change accounts on your Mac, go to System Preferences, sign out of the current account, then sign into the new account. When you sign out of the current account it will delete synced data from your Mac. Assuming your data (such as contacts, calendars, etc.) is in the other iCloud account, it will be synced to your Mac when you sign into this account.

We had a MacBook Pro stolen from our home when we were out of town and I am pretty sure we never activated the LoJack type of function on it not sure if its called lojack but you get what I am saying is there any way we can activate such hardware/app now so we can possibly recover our laptop? Any one who can point us in the right direction that would be great and we would be very grateful. Thanks So MuchLojack for laptops - if that is the product you purchased and installed, you will need to read the user manual or contact the manufacturer as it is 3rd party. You did file a police report right?

Me and my partner have just brought a new MacBook. We both have individual iTunes and iCloud accounts, is there any way we can access both accounts on one computer?
Set up 2 accounts one for each of you.

My parent's IPad is SUPER outdated and I'm trying to buy an app for my brother for Christmas. However, I can't buy the app because it says we need to update the software. The thing is, the computer that was connected to the IPAD, we no longer have. So is there any way I can update it on my mac without erasing all the photos and videos?
HELPPP ME BEFORE CHRISTMASS MORNING!!

On iTunes 11, how can I access home sharing if the music is from a CD on a different computer using Home Sharing? Is there any way I can download these songs if (A) I no longer have the CD, or (B) I do not want to pay $25 a year for iTunes Match?
Yes, you can copy songs that you ripped from a CD to your Home Sharing computer.
Turn on Home Sharing first on both computers. To do that, go to File > Home Sharing > Turn on Home Sharing. Enter your Apple ID and password.
Now go to your computer that you want to copy the songs to and connect to your Home Share. You can do that by clicking on the popover button located at the left top corner right below the play control buttons. Click on it and scroll to the bottom until you see your Home Share and select it.
Go to Music in your Home Share. Select the songs that you want to copy in your Home Share and click Import at the bottom right corner. -
I had files stored on a hard drive that were not on my Mac. I used the hard drive for my first Time Machine back up, but it was not enough hard drive space to finish. Now those stored files are gone. Is there any way I can recover them? No, they were not part of previous Time Machine backups, and I have checked both the hard drive the documents were lost on and the new one that I now use for backups. Any suggestions would be helpful, as the lost files are old pictures that are gone forever. :[ Thanks!
1. Yes, if both drives are formatted as Mac OS Extended (Journaled).
2. Reformat the drives if needed, open the Time Machine pane of System Preferences, and remove the drive with the pictures from the list of items set to be excluded.
