Cannot update 'last_update' column, please help

I want to add a column 'last_update' in all tables in database, then add a tigger to update 'last_update' timestamp after the row is updated. However, tigger cannot allow me to update 'last_update' field on updating row. The error is ORA-04091 means table is mutating. How can I solve the problem ?

according to your reference, my trigger is as below:
CREATE OR REPLACE TRIGGER lastudt
After UPDATE ON test
FOR EACH ROW
BEGIN
:new.lastupdate:=sysdate ;
END;
but, i got
ERROR at line 1:
ORA-04084: cannot change NEW values for this trigger type

    Hi. The two user tips both describe a sequence of steps that should get your library from the point where it threatens to wipe data from your device to where it is syncing normally, while recovering as much information as possible. It may still be necessary to wipe and reload the device but this should only take place once all the data that can be recovered has been recovered.
    Doing step 1 of 8 and then complaining things aren't the way you want them to be yet strikes me as premature...
    Since you appear to have all your media content, and we are discussing an iPod classic, not an iOS device, the main worries are already taken care of. What's left is ratings, playcounts, playlist membership and checked status. Since your device holds only part of your library at best you could only recover the missing data for the content that is on the device using third party tools.
    Recreating the previous checked/unchecked status of every track in your library from where you are now may not be that easy. Syncing with selected playlists has many advantages, one of which would have been that you would have a named playlist that could have been retrieved by 3rd party software if you had used this method.
    You haven't explained what caused your problem in the first place, but if you have a Previous iTunes Libraries folder holding old copies of your iTunes database (generated with each iTunes update) then it would be possible to restore the most recent of these and then update the library with any changes in your media folder.
    BTW Apple doesn't offer free support for this kind of issue with iTunes.

    Bluetooth shuttted down after I updated to Mavericks, please help me !
    I am 70 Years old and worked very happy with my iMac (21,5“ mid 2010, 3,2 GHz Intel Core 3)
    until I updated him from  SnowLeopard 10.6.8 to Mavericks 10.9.2.
    2 Days all was OK. Next Morning-Start he needs (until now) 3 minutes to show me a SCREEN only milky white. After that he starts like ever with all ICONS in about 1 minute. (together 4 min.)
    ..But I must notice, that I cannot make anything, because the „BLUETOOTH APPLE WIRELESS KEYBOARD  and the APPLE  MAGIC MOUSE“ doesn't work anything like before.
    I could nothing do, I must drop my APPLE only out.
    That I maked ever 10x and all was the same... (Maveriks also 4x new updated)
    I taked my Logitech-Bluetooth-Mouse from the WIN-Laptop, dropped it in USB from iMAC...and in one second I could work only with this MOUSE...I buyd the Logitech COMBO K520 and all was OK now with my lovely APPLE iMAC to work with him...But without APPLE KEYBOARD and MAGIC MOUSE...and with a 4 min. -START until now.
    I  asked the EXPERTS from APPLE-SUPPORT under Tel. 0800-6645451 in Germany, became a Number, maked many Things by starting new, but the mistake after all is the same like before.
    When I look into ...Apple/ Info/System/ Hardware/ Bluetooth   ..my APPLE says: NO INFOs FOUND (Es wurden keine Informationen gefunden.)
    Under Hardware/ Diagnose : Selbsttest beim Einschalten: zuletzt ausgeführt: 15.05. 14, Ergebnis: Bestanden (that means OK) !!
    I asked many Peaple, who sold APPLE-Computers in the STORS, but they all had no IDEA, how they can help.
    I think, it could be a DRIVER when Starting the BIOS, JAVA RUNTIME a.s.o...
    Is an Expert under YOU to help me by my Problem with this iMAC ?

    dietmarfromdeu,
    if you start up your iMac in Safe mode, do you still have Bluetooth problems with your Apple wireless keyboard and Magic Mouse?

  • The older version of iTunes cannot be removed. Please help!

    I had to manually delete iTunes from my Windows 7 PC. When that didn't work, I deleted iTunes from the Registry. There is no older version of iTunes anywhere.
    I still cannot reinstall iTunes. Please help. Thank you.

    (1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
    http://majorgeeks.com/download.php?det=4459
    (2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
    (3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
    (4) In the list of programs that appears in CleanUp, select any Apple Software Update entries and click "Remove", as per the following screenshot:
    (5) Quit out of CleanUp, restart the PC and try another iTunes install using an iTunesSetup.exe (or iTunes64Setup.exe) downloaded from the Apple Website:
    http://www.apple.com/itunes/download/
    Does it go through properly this time?

  • I can't connect to wifi at home on business hub ? So cannot update my iPhone 5  Help!

    I can't connect to wifi at home on business hub ? So cannot update my iPhone 5  Help!

    wifi is wifi, and business hub means very little.. this is area for time capsule discussion.. but the standard measures apply.
    1. Set wireless name (SSID) to a name that is short, no spaces and pure alphanumeric. Eg your Business Hub call wireless BH. There is no need for names longer than that.
    2. Set wireless channel for 2.4ghz to 11 or 6 or 1. Please test in that order. In Eurozone you can add 13 or use it instead of 11. They are the only 3 non-overlapping channels.
    3. Use no security to test.. of course this is unsafe long term.. so this is to test for a few minutes only.
    The only security that should be used with N wireless is WPA2 TKIP-AES .. it can be named several different things ie in Apple routers it is WPA2 personal. Use a passkey of 10-20 characters.. more if you are paranoid, mix of upper and lower case + numerics.. so pure alphanumeric.
    4. If it fails set the mode to G wireless. It is more consistent standard.
    If it still fails buy an Apple router and use that as WAP.

  • My ipod touch is stuck on the 4.2.1 software, its a 3rd gen as well i was just wondering why i can not get the lastest update can you please help me with this issue

    i have been having an issue with updating my ipod touch for some time now and i can not seem to get it to update to the lastest update. it is stuck on 4.2.1 software and i can not update it to 4.3 or any other ios software update. can you please help me to solve this issue.

    It sounds like you actually have a 2G iPod Touch which can only go as high as iOS 4.2.1.  If it's an 8 GB iPod Touch it's definitely a 2G iPod Touch as there was never such a thing as a 3G 8 GB iPod Touch. See this article to help verify what generation iPod Touch you have.

  • HT1420 I have the new version of the macbook pro and I cannot find authorize this computer anywhere on itunes. I have read the directions multiple times and still cannot find it. Please help!

    I have the newer version of the macbook pro and I have read the directions on how to authorize your computer to let you download previous song purchases from icloud onto your laptop, but I cannot find where it says "authorize this computer" at all. I have looked for it everywhere and still cannot find it. Please help!

    Authorization and Deauthorization
    Macs:  iTunes Store- About authorization and deauthorization.
    Windows: How to Authorize or Deauthorize iTunes | PCWorld.
    In iTunes you use the Authorize This Computer or De-authorize This Computer option under the Store menu in iTunes' menubar. For Windows use the ALT-S keys to access it. Or turn on Windows 7 and 8 iTunes menus: iTunes- Turning on iTunes menus in Windows 8 and 7.
    More On De-authorizing Computers (contributed by user John Galt)
    You can de-authorize individual computers, but only by using those computers. The only other option is to "de-authorize all" from your iTunes account.
      1. Open iTunes on a computer
      2. From the Store menu, select "View my Account..."
      3. Sign in with your Apple ID and password.
      4. Under "Computer Authorizations" select "De-authorize All".
      5. Authorize each computer you still have, as you may require.
    You may only do this once per year.
    After you "de-authorize all" your authorized computers, re-authorize each one as required.
    If you have de-authorized all computers and need to do it again, but your year has not elapsed, then contact: Apple - Support - iTunes - Contact Us.

    Yes. You can't update or restore any GSM iPhone without a valid sim card installed in the phone. The sim card need not be activated, but it must be valid & present. If you want to update, you need to get a sim card.

  • My iphoto wont open since i updated my mac, please help? it says i need to install an iphoto library upgrader which I have installed but still cant see my photos.

    my iphoto wont open since i updated my mac, please help? it says i need to install an iphoto library upgrader which I have installed but still cant see my photos.

    What version of iPhoto are you using? 9.6 is the current version.
    Do a backup.
    Quit the application.
    Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J.  When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder.  Select Library. Then go to Preferences/com.apple.iPhoto.plist. Move the .plist to your desktop.
    Restart, open the application and test. If it works okay, delete the plist from the desktop.
    If the application is the same, return the .plist to where you got it from, overwriting the newer one.
    Thanks to leonie for some information contained in this.

    i updated the spelling of a song in my itunes but its not reflecting when i check my ipod. this never happened before when after i updated to IOS5. please help.

    Try unsyncing the sone and then resyncing. That works sometimes. Sometimes restoring from backup works. Other times nothing seems to work.. Yuo are not alone since iOS5 and iTunes 10.5/6.

  • Trans. Replication failing -- "Cannot update identity column ..." -- unable to use sp_browsereplcmds to view statement

    All, I'm trying fix an issue with transactional replication where replication monitor is showing the push to the subscriber is failing because of the error, "Cannot update identity column."  I've tried to use sp_browsereplcmds to pull up the
    command that's failing based on the xact_seqno but when I try that I get the error:
    Number: 102, State: 1, Procedure: , LineNumber: 0, Server: , Source: .Net SqlClient Data Provider
    Message: Incorrect syntax near '┻'.
    I'd like to fix the issue without having to rebuild replication during a maintenance window.  I know you cannot publish tables with primary keys, but I'm wondering if dropping the identity column on this table might fix the issue.  I'm considering
    that but I would prefer to be able to pull the command that's trying to update the identity column, throw in SET IDENTITY_INSERT ON and remove the commands from the distribution database, but if that doesn't work I'm open to ideas of just dropping the primary
    key on the replicated table.  I think that should be fine.
    Does anyone have any recommendations on how to view the command that's failing?
    Or if dropping the primary key on the subscriber table would create issues with the publisher (since it is also the primary key)?
    Or, know of any other ways in which to address this issue?  Thanks.

    Unfortunately, no.  The error was a bit of a red herring.  In the end the subscriber was missing all of the stored procedures needed to update data in the published tables (i.e., the procedures for performing inserts/updates/deletes were missing
    for every table in the subscriber database).  Additionally, I could not recreate these stored procedures using sp_scriptpublicationcustomprocs
    because another procedure which was required for that proc to work was also missing. In short, there were hundreds of missing stored procedures in the subscriber database on which transactional replication is dependent in order to replicate DML changes and
    function normally and this includes system sprocs which would've been used to recreate the missing DML procs. In short, the subscriber was badly damaged and deemed to be unrecoverable within a reasonable time frame.
    The solution was to tear down and start over, which we did successfully later in the evening.

    When I try to download games eg. Dreamland HD light it says the following: your request cannot be completed. Please help.

    Honestly, these are WAGs but they're all that I can think of.
    First, try a system reset.  It cures many ills and it's quick, easy and harmless...
    Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo.  Ignore the "Slide to power off" text if it appears.  You will not lose any apps, data, music, movies, settings, etc.
    If the Reset doesn't work, try a Restore.  Note that it's nowhere near as quick as a Reset.  Connect via cable to the computer that you use for sync.  From iTunes, select the iPad/iPod and then select the Summary tab.  Follow directions for Restore and be sure to say "yes" to the backup.  You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.  Again, say "yes."
    Finally, if the Restore doesn't work, let the battery drain completely.  Then recharge for at least an hour and Restore again.
