You could pick up examples from introductory books on Oracle.
For example the Certification Guides for the Oracle SQL Fundamentals Guide (1Z0-051 http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=5001&get_params=p_exam_id:1Z0-051&p_org_id=&lang= ) . Search bookstores / amazon.com for books for 1Z0-051
You could also look at Jason Price's book Oracle Database 11g SQL : http://www.amazon.com/Oracle-Database-11g-SQL-Press/dp/0071498508/ref=sr_1_1?ie=UTF8&qid=1372742972&sr=8-1&keywords=Jason+Price

Hey allen72,
Thanks for the question. I understand you wish to transfer your iTunes library to a new computer. There are a few different options for doing so, the following article provides more information:

You may have installed a variant of the "VSearch" ad-injection malware. Follow Apple Support's instructions to remove it.
If you have trouble following those instructions, see below.
Malware is always changing to get around the defenses against it. This procedure works as of now, as far as I know. It may not work in the future. Anyone finding this comment a few days or more after it was posted should look for a more recent discussion, or start a new one.
The VSearch malware tries to hide itself by varying the names of the files it installs. To remove it, you must first identify the naming pattern.
Triple-click the line below on this page to select it, then copy the text to the Clipboard by pressing the key combination command-C:
/Library/LaunchDaemons
In the Finder, select
          Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
A folder named "LaunchDaemons" may open. Look inside it for two files with names of the form
          com.something.daemon.plist
and
           com.something.helper.plist
Here something is a variable string of characters, which can be different in each case. So far it has always been a string of letters without punctuation, such as "cloud," "dot," "highway," "submarine," or "trusteddownloads." Sometimes it's a meaningless string such as "e8dec5ae7fc75c28" rather than a word. Sometimes the string is "apple," and then you must be especially careful not to delete the wrong files, because many built-in OS X files have similar names.
If you find these files, leave the LaunchDaemons folder open, and open the following folder in the same way:
/Library/LaunchAgents
In this folder, there may be a file named
          com.something.agent.plist
where the string something is the same as before.
If you feel confident that you've identified the above files, back up all data, then drag just those three files—nothing else—to the Trash. You may be prompted for your administrator login password. Close the Finder windows and restart the computer.
Don't delete the "LaunchAgents" or "LaunchDaemons" folder or anything else inside either one.
The malware is now permanently inactivated, as long as you never reinstall it. You can stop here if you like, or you can remove two remaining components for the sake of completeness.
Open this folder:
/Library/Application Support
If it has a subfolder named just
           something
where something is the same string you saw before, drag that subfolder to the Trash and close the window.
Don't delete the "Application Support" folder or anything else inside it.
Finally, in this folder:
/System/Library/Frameworks
there may an item named exactly
            v.framework
It's actually a folder, though it has a different icon than usual. This item always has the above name; it doesn't vary. Drag it to the Trash and close the window.
Don't delete the "Frameworks" folder or anything else inside it.
If you didn't find the files or you're not sure about the identification, post what you found.
If in doubt, or if you have no backups, change nothing at all.
The trouble may have started when you downloaded and ran an application called "MPlayerX." That's the name of a legitimate free movie player, but the name is also used fraudulently to distribute VSearch. If there is an item with that name in the Applications folder, delete it, and if you wish, replace it with the genuine article from mplayerx.org.
This trojan is often found on illegal websites that traffic in pirated content such as movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
Then, still in System Preferences, open the App Store or Software Update pane and check the box marked
          Install system data files and security updates (OS X 10.10 or later)
or
          Download updates automatically (OS X 10.9 or earlier)
if it's not already checked.

I can't login, keep geting "Your Startup Disk is Full" and asking me to delete file. if I cant login how can I delete files? Please help

I Keep getting "your startup disk is full" ..... "You need to make more space available on your startup disk by deleting file..." If I can't have an acess, how can I delete files. Please help..

That means the hard drive of your computer is full, and you don't have enough free space on your computer, to do what you are trying to do.
You need to clear up space on your computer.
If you hard drive is full, check the following places to ensure they are not holding unwanted data.
- your trash can in the dock
- if you use iPhoto, your trash in iPhoto - launch iPhoto, and select trash in the left hand column. iPhoto has it's own trash, and is often overlooked
- your download folder - finder / home user / downloads - every time you download something, it stores it here. This is often overlooked as well
- do you have more than one user on the computer? If you do, ensure they are needed. If not, delete them, and the contents of their home folders
If you hard drive is very full, you may want to consider the following:
- putting in a newer larger hard drive - (call you local apple store for prices on this)
- deleting data off your computer
- moving data to an external drive - (iPhoto Libraries, iTunes Libraries or iMovie events, as they are the biggest space hogs)

How to make it more efficient

Hi,
I am working on AQ where I am just sending and receiving simple messages. But the performance is very poor. It takes around 35 seconds to send (enqueue) just 100 messages which is not acceptable for our project. Can someone help me how to make it more efficient. I am using JMS for sending and receiving messages.
Thanks,
Sateesh

Bhagath,
Thanks for your help.
Oracle server we are using is 8.1.7. We are using JDBC client that ships with Oracle client (classes12.zip).
Right now we are working on point to point messages.
I am just wondering whether I need to do any tuning on server.
Your help is greately appreciated.
Here I am pasting sample code that I wrote which may help in finding the problem.
Thank you so much once again for your help.

Gotcha, sorry, I'm guessing you are referring to Windows Autoplay. This should do it:
Type regedit into your search bar and bring up Registry editor. Go to the the very top with My Computer. Now go to Edit and Find. Type in the whole offending name that is bugging you, i.e. Soandso's iPhone and hit find. After it searches your registry and finds the first name select it and Edit the Name. I copy/pasted it for all the next steps. After you have found the first name don't stop there. Use F3 to find next Name in registry and So on and so fourth until you have replaced every offending name in your whole registry with the Name you want to show up i.e. Tom's iPhone or whatever? Repeat all of these steps if you have more than one name showing up in your devices? Worked 100% for me. Close regedit and reboot (very important for changes.) Plug your iPhone back in and enjoy all your names back to normal.

Please help, Thank you.

Your photos remain in place, the catalog you have been using will remain. After you install Lightroom from the CC, all you have to do is open your existing catalog and continue right where you left off.

You have the display set in Extended Desktop mode. The Menu Bar and Dock will be on the MacBook display and your background screen on the monitor. In System Preferences>Display on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the monitor and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen. You can now use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse. http://support.apple.com/kb/HT3131 When you disconnect from the monitor your Menu Bar will automatically change back to the MacBook.

Please help me..

Accidental damage is not covered under Apple warranty. And it seems there is much accidental damage. Only a Genius Bar tech looking at it can tell how much it will cost to repair.
Cost to repair will be high, I suspect (though Genius Bar will confirm/deny.
There is no gentle way to say this sir/ma'am ... someone will need to pay for your friend's MBA repairs.

Delete the shortcut and make a new one. The 'real' application will probably be fine if you launch it from the Start/Programs menu.
