How can you optimize sql and pl_sql?

Please I need some one give me some examples

How do I set between sql and pl_sql
and I need many examples because there has been talk at the interview

This isn't the only "interview" question you asked. Let's face it, if you do not know the answers, then be honest and say you do not know the answers, do not try and get a job by pretending you know things you haven't otherwise you'll end up in a job, you cannot do and let the employer an employee who cannot work, so wasting their time and yours.

    ==========================================
    Photoshop is a real program produced by Adobe and Yes, the
    Word is often used in reference to photos that have been published.
    "Looks like it has been retouched.

    Adobe Photoshop is not freeware, but they offer a trial version
    You can use for a time limited.

    There are many image editors and a number of free but if
    you have a fast internet connection following free online
    the Publisher may be worth a try. At least it would give you an idea of
    what you agree.

    You mentioned "do the eyes and nose larger/smaller'...try the"
    following steps.

    When you open the form from the Publisher if you press the F11 key
    your keyboard, it must develop in full screen.

    First of all, you need to upload a photo. On the screen of the editor... go...
    File / open my computer and navigate to the photo you
    you want to change. When the photo is displayed in the box for editing... go to
    See / adapt to the screen.

    Now, go to... Filter / distortion / pinch.

    In the palette of pinch... try dragging the sliders at the top of the page
    in the Center... now when you drag the cursor to the lower left or right
    from scratch... it should contract or expand the center of the face
    (this assumes that the face is centered on the photo).

    If you arrive at a result, you are happy with click left OK and you
    can save the image as follows...

    File / save to my computer...

    Enter a new name for the edited version, so it will not delete
    the original.

    Select... JPG / 100 / Save...

    In few seconds the backup screen will appear... Choose a backup location...
    Desktop might be a good choice... then on the left, click the "Save" button.

    If you wish you can download and install a program on your hard drive...
    the free version of Serif PhotoPlus 9 might be useful to try:

    (FWIW... it's always a good idea to create a system)
    Restore point before installing software or updates)

    (left click the button "Download PhotoPlus SE")

    Here is a link to a .pdf of the PhotoPlus 9 manual version.
    http://www.serif.com/community/PDFs/PhP9companion.PDF
    (when it appears on the screen... you can download a copy to your hard drive
    drive by going to... File / save as... Choose a backup location and left
    Click on the "Save" button)

    And the following link may be worth a visit:

    Be aware that there is a learning curve a little stiff with image
    editing software and since you are running Vista Basic... you can
    have resource problems. The program can be very slow, and in some
    instances, you will notice that it will freeze.

    Good luck and have fun: o)

  • How can you change a form you've already created?

    I do not speak for the form fields. I mean if you have a typo in, for example, in the docuyment that you have created in InDesign and now you must go back and correct it. How can you do this and maintain any fields that you have already created?

    If you are not able to do this, it would be a huge flaw in the workflow.

    The easy way is to make the change in InDesign, re-export the PDF file and then use Pages to replace in the Document Menu to replace the content of the original with the corrected file file. He maintains the form fields to their original position.

  • How can you transfer all data and software form old iPad new iPad?

    Hello: I have an iPad 9.7 "display of 2012 with 16 GB of storage. I'm about to storage now and are considering buying an iPad 2 Air. My question is, how can you transfer all the info from my old iPad to the new without starting from scratch?

    Thank you, Gilbert.

    < email published by host >

    Whence the content come of for example you have the music on the iPad, and if so is sometimes copied from CDs? You can copy purchases on iTunes from your computer via file > devices > transfer purchases, make a backup of the iPad, and restore this backup on the new iPad (music, videos, etc. is copied from the iTunes library, not the actual backup, so you will need these items in the iTunes library).

    Transfer to a new device: transfer the contents of an iPhone, iPad or iPod touch to a new device - Apple Support

    Sorry, but the restriction password cannot be reset, it is part of the backup and restore a backup that was taken after the restrictions were activated, restore this code again.

    You will have to start without the help of the data backup, configure the phone to factory settings and start over. Follow the steps mentioned in this article:

    Use iTunes to restore your device to factory settings - Support Apple iOS

    If you lose or forget your password restriction, you must erase your device and then put it up as a new device to remove the restriction password. Restore the device by using a backup does not delete the access code.

  • Windows 7. But the name of the account user each time before fully loading windows. How can I stop this and simply load in thank you Windows.

    I have just upgraded to Windows 7. But whenever I turn on my computer, he wants to support me on my user account name before completely loading windows. How can I stop this and simply load in thank you Windows.

    Hi UKuser7,

    Welcome to Microsoft Answers Forum.

    Automatic logon is disabled in Windows 7 by default for security reasons. If it is enabled, anyone who can physically access the computer can also gain access to everything on the computer, including the networks that it is connected.

    This setting is only recommended for cases where the computer is physically secure.

    To set up Windows 7 to connect to the desktop automatically, follow the steps below.

    1) click Start , and then enter the following command in the start search box:

    Netplwiz

    2) press ENTER.

    This opens the Advanced user accounts Control Panel window.

    (3) in the users tab, uncheck the box next to users must enter a user name and password to use this computer.

    4) click apply at the bottom of the user accounts window.

    (5) when the newspaper automatically on the dialog box appears, enter the user name for which you want to automatically connect to Windows 7. Then enter your password in the two areas where it is requested.

    6) click on the OK button.

    7) click OK in the window user accounts to complete the process.

    Thereafter, your PC at startup, Windows 7 will be automatically connect.

    Ticket back for your comments and concerns.

    Kind regards

    original title: How can you recover files, folders, software and drivers after reinstalling windows xp family? Please help, I've lost everything!

    When the update Norton Internet Security 2009 to 2011 on reboot, windows cannot open.

    Root\systems32\hal.dll Windows prevented windows from opening.  My machine in a Dell dimension 8300.

  • How can you know what drivers and programs are essential and those that can be deleted without harming my computer?

    Original title: completely clueless

    I'm totally clueless when it comes to computers, but I try very hard to learn. I am using the help section a LOT, but I can't seem to find an answer to the only thing that makes me crazy. How can you know what drivers and programs are essential and those that can be deleted without harming my computer? I have a very basic net accountant I learn on before I screw up a portable more expensive and I do a cleaning on my C and D drives to improve performance because it runs so slow but it tells me I have the drivers who slow down Windows. I would greatky appreciate any assistance from someone who has the patience of a saint and is willing to take the time to explain it to me, in terms laymans. Thanks in advance

    Drivers: you should know what you bought (in your machine) and what * you * want out of it.  If you want stability and things work properly - let alone the drivers.  If you want more performance check (and other games) in the drivers of motherboard chipset and video network from the manufacturers Web site... For more stability stick with the OEM website (HP, Dell, Lenovo - the assembler of the whole machine) and slightly more performance/push the limits (even if they want to work too - so still some stability) - access to websites of its components manufacturer.

    With regard to the programs: you can decide what you use and do not use.  If you are not sure, look it up (Google) or ask.

  • How can you stop the toolbar of 'charm' of popping up all the time and this HUGE clock

    How can you stop the toolbar of 'charm' of popping up all the time and this HUGE clock... I am new to windows 8 and I do not... I much prefer to have windows 7 return... any suggestions?

    I preached this whole week... my pleasure to increased win8 x 100 once I turned off the edge of the touchpad scan function.  The path may be slightly different, but the synaptics touchpad is the Control Panel / hardware and audio / mouse / device settings / settings / edge shot - and disable "enable edge scans".

    This prevents context changes maddening when browsing the web or doing anything on the touch pad really... you can always access the charms on the right upper or lower, and you can always access history FRO the top left corner after that you disable this... but it is much more controlled.
    hope this helps
