Is there any way to restore data truncated with TRUNCATE query in Oracle9i

Hi, Is there any way to restore data truncated with TRUNCATE query in Oracle9i DB...
Thanks in advance...

Hi,
you can flash back DML queries like insert, update
but it is not possible for some DDL like truncate, alter, and and drop columns etc that change structure of table.
e.g.
SQL> select * from t2;
C1
3
SQL> select dbms_flashback.get_system_change_number from dual;
GET_SYSTEM_CHANGE_NUMBER
496378
SQL> truncate table t2;
Table truncated.
SQL> select * from t2 as of scn(496378);
select * from t2 as of scn(496378)
ERROR at line 1:
ORA-01466: unable to read data - table definition has changed

  • Is there any way to restore data from an external drive to another external drive without using the macbook pro you backed up?

    Is that I sold my macbook pro an the person who bought it needs it quickly so I have an external drive but it is not portable so I bought a portable external drive but it may take a while to arrive so I backed up my data with the external drive that I have in my house but I would like to know if I can restore my data to the new external drive without the macbook pro and just with the external drive of my house to the portable external drive.
    Thank you

    No, that's not possible. A computer is required in order to effect such a transfer. Connect both drives to your computer. You can use Disk Utility to clone one drive to the other. Be sure you first partition and format the new drive:
    Drive Partition and Format
    1. Open Disk Utility in your Utilities folder.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.
    Clone using Restore Option of Disk Utility
      1. Open Disk Utility in the Utilities folder.
      2. Select the destination volume from the left side list.
      3. Click on the Restore tab in the DU main window.
      4. Select the destination volume from the left side list and drag
           it to the Destination entry field.
      5. Select the source volume from the left side list and drag it to
          the Source entry field.
      6. Double-check you got it right, then click on the Restore button.
    Destination means the new external drive. Source means the old external drive.

  • Is there any way to restore an iPhone with a shattered screen, broken home button, with a passcode and no access to computer most recently synced with?

    I have an iPhone with a completely shattered screen (the display wont even show up, just a black screen), the home button does not work. I have a passcode on the device, but I have not synced the device with my current PC (I got a new computer and don't have any of my syncs from my old computer). I recieved my replacement device today, and want to back up the iphone before I activate the new device - but I get prompted to put in my code on the phone before it will allow me to back it up. As the display is completely black and does not appear to respond to touch, and the home button is broken so I cannot put it in recovery mode... What do I do? If I took the phone in to my carrier's store, would they be able to override the passcode and put my information on my new device?

    Sorry, no. Given the present state of your phone, your data is unrecoverable.

  • The data fields in a filled-out PDF form disappeared after a crash.  Is there any way to restore the lost entries?

    Adobe Reader crashed while I had a filled-out Adobe PDF form open.  When I reopened the file, I found that all of the data that had been entered into the form fields had disappeared.  Is there any way to restore the data that is missing?
    I note that the "Restore" command in the Adobe Reader file menu is not available (grayed out).
    Thanks for your time.

  • All of my contacts were deleted for no reason. Is there any way to restore them?

    I powered down my iPhone 4S because an app was bugging out. When I powered it back up, all of my contacts had been deleted. When I tried to see my contact list it told me there were "No Contacts" on this phone. In the "messages" app, each conversation is now paired with a phone-number and not each contact's name.
    I did not have my contacts sync'd to my iTunes, or iCloud, or any other storage system.
    Interestingly, when I do a "left-swipe search", and type in a contact's name e.g. Joe Smith, my phone is able to show me which text-message conversations were with Joe Smith, and other information about this contact. But that's the only memory my phone has of its lost contacts.
    Is there any way to restore lost contacts without external storage / syncing ??
    Thanks

    I think those contacts still in iphone database. So you can back up you iphone with itunes to get iphone database off your iphone. Then access the SQLite batabse.
    http://support.apple.com/kb/HT1766
    All data included with the backup is stored in a SQLite database format with the data within various folders not easily accessible.There are some 3rd party utilities that provide for extracting select data from an iPhone's backup and iphone database such as this one.

  • I have apparently wiped out my iPhone 4 contacts list, my apps, and my photos, etc. by syncing with iTunes.  Is there any way to restore what I had?

    I have apparently wiped out my iPhone 4 contacts list, my apps, and my photos when I synced with iTunes.  Maybe I clicked the wrong button, but I just wanted to download the photos from my phone to my computer.  Is there any way to restore my previous information?

    Did you sync to itunes from a different computer than the one you normally sync to?
    syncing to itunes doesn't just wipe out all your data.
    If you have a backup of your phone you can restore to that backup.

    Is there any way I can find it.What kind of restoration? What kind of files?
    The usual "no information" question is of the form "My car won't start. Tell me how to fix it"
    Yours is a bit different - "I tried to fix my car. Tell me how to know it's fixed".
