Problem of ORA-00918 join of tables for the update

Hello

I have 2 tables: PAR_SPEC_OPS and T_PAR and I'm trying to update the 2 columns with values from the second table in the first.

Here is my script:

Update
(
Select membership_id, membership_status
Of Par_Spec_Ops P, T_Par T
Where P.Tracking_ID = T.Tracking_ID
)
Set P.membership_id = T.membership_id,
P.membership_status = T.membership_status;

Running this gives me ORA-00918: column ambiguously defined. I watched this and it is said that happens when there is a common column in tables 2 and I'm not using prefixes, but as you can see on my order, I'am using prefixes. I tried with and without alias, but I get the same error.

You guys have any ideas?

Thank you and best regards,
Ionut

    I love the develop module, but I'm doing something wrong in the library

    In the library, under 'Catalogue, all the photographs', all my photos appear showing the stars, cropping, and development. The problem is that these changes are not for the photos on my hard drive. When I re-import them in Lr, the changes are not there. My workflow is to do nothing after development or export them to the original with a new file name destination. Anyway, it is that they get a new file name without change of development when they are imported into Lr.  Please help (PC user)

    And others have explained, Lightroom does not apply the changes to the file. All changes are stored in the catalog, and then applied to the image when it is displayed in Lightroom. If you want a copy of the image with any changes so that you can share with others or send it to a laboratory to print, then you must export a copy of this image by using the export dialog box in Lightroom.

    Features of Lightroom as well by its design. The images that you import are always left in their original condition, unmodified.

  • ORA-20001: unauthorized access (package for the undefined security group variable).

    I'm creating an application that uses the authentication of the APEX and characteristics (work) registration and forgot password forms (does not work).

    My I forgot the password is public (requires authentication). The user provides the user name and a secret answer, which are validated and then provides the new password. I try to use htmldb_util.reset_pw to reset the password of the user, but it does not work.

    I have a process on the new password page call a PL/SQL anonymous block that looks like this (see below), where username = P16_ITEM1 and P18_ITEM1 = new password.

    BEGIN
    apex_040000.htmldb_util.reset_pw (V ('P16_ITEM1'), V ('P18_ITEM1'));
    END;

    I don't know how to send a message of success/failure of such PL/SQL block to the APEX, but that's a separate issue, I guess.

    In any case, during the trial through SQL Developer as the user with APEX_ADMINISTRATOR_ROLE, I get the following error:

    ORA-20001: unauthorized access (package for the undefined security group variable).

    When executing code outside the Apex which depends on the security defined Apex group, perform the following steps before your own code:

  • Satellite 4090 BIOS number - message "ready for the update BIOS... ' appears

    Hi all! Excuse my poor English because I'm french.

    A friend gives me his cell phone (a Satellite exactly 4090CDS) because he had a problem.
    In fact, the problem is that when I turn on the computer, I have a single message (not even the toshiba red logo) that is "ready for the update of the BIOS. Place the BIOS update floppy in the drive and press any key when you are ready to move forward."

    So I go to the french site of toshiba, in the BIOS download, I find that I must download this update: http://support.toshiba-tro.de/tools/bios/satellite/4030-4060-100/bios_820.zip

    OK, I download and unpack it on a floppy disk and I start the laptop with the disjette, he said that the update has been successful and it restarts automatically.
    This time, the Red toshiba logo appears, but then I have a black screen with a message:

    Bad checksum (CMOS) *.
    Check the system. Then press the [F1] key.

    And after that, I can't do anything, not even, press F1. If I restart the laptop, I myself meet once more with the first message «Ready for the update of the BIOS...» "and it's still the same.

    If someone could help me understand what the problem is, that would be fine.
    Thank you.

    Bastien.

    It sounds as if your CMOS chip has a problem. It is possible to s that the CMOS battery has failed and the BIOS settings are lost.
    Maybe the RTC battery is empty. In this case, you should connect the AC adapter to charge the battery of the CCF.
    Please note that the RTC battery (CMOS battery) can be fluffed once the main laptop battery has been recharged. In this case, the charge process may take several hours.

    But if after this long process of load this message appears again then I guess the battery is dead.
    I suggest that you only contact your ASP closest to get your phone checked.

    Hi Sarma_RN,

    1. When you receive the error message?

    2. update you are trying to install?

    3. When was the last time you were able to install updates?

    If Windows Update, error 80072ee2 during updates, the Windows Update servers may experience an unusually high number of requests for updates. Close Windows Update, wait 10 to 15 minutes, and then run Windows Update again. Alternatively, you can wait for automatic update of Windows run at its next scheduled time.

    These errors can occur caused by one of the following problems:

    • Applications or processes that interfere with Internet communications
    • Problems on your computer
    • Strong Internet activity
    • Recoverable database errors

    See the Microsoft article and try the steps mentioned below.

    I am running Windows 7 and noticed that Windows updates did not work. The parameters are defined for the update every day. When I went to update manually returned an error WindowsUpdate_80070017.  MSFT site was no help. Any recommendations?

    Since neither updates Jan - 10 have installed, I'm going to hand you Support MS in the hope that they can resolve the problem. See below.

    That being said, is an interpretation of the 80070017 - cyclic redundancy check error "a device attached to the system does not work," which suggests that a hardware problem might be the cause of the error (although I must say that it is a very low possibility in this case).

    Good luck!

    It is a decision that was made by Apple.  El Capitan is the newest OSX that will support a 2009 MBP.
