Unable to connect to an application after moving from Apex to Apex 5.0 4.2

Hello

I have an APEX application which the login is authenticated with a password (encrypted) in the database.

After you import a request of APEX 4.2 to APEX 5.0 to a different database, here is the error I get when I try to connect from page 1:

ORA-00918: column ambiguously defined

Treatment of error condition.

And here's the info I can find from the debug log:

Does anyone has an idea of the problem?

Thank you in advance.

Kind regards.

Hi Patrick,

Thanks for your response.

You gave me good advice, I was exploring just the look and feel of the APEX 5.0 and it is still a Terra Incognita.

Although the Advisor provided advice nany to be alert in, I found the problem.

"PL/SQL errors" referred to in the report of the Advisor stressed (at least) a request that identify the database the user record.

This query worked very well in the original request of the APEX. So, I could not believe that it is a real "syntax error".

The problem seems to have been the DataPump data import.

A subsequent investigation showed that some tables were not created properly. There where some columns missing ID and also the column date was not correct.

For a table, a column that was missing has been used in a join to identify the user.

As a result, the column was "ambigously defined."

Kind regards

    Original title: I accidentally turned off the program that allows my computer to connect to the Internet

    Hi Tunasushiroll,

    Thanks for posting your query in Microsoft Community.

    I imagine the inconvenience that you are experiencing and will certainly help you in the right direction to solve the problem.

    The problem can occur for various reasons, including incorrect TCP/IP settings configured, firewalls third of anti-virus programs blocking the connection, or due to bad the advanced sharing settings. So, I would suggest trying the following methods and check if you system is able to detect the wireless network.

    Method 1:

    Run the troubleshooter network first, and then test your Internet connection.

    Open the Network Troubleshooter by hitting on any fly in the Dashboard screen, quilting Search(or if you use a mouse, pointing to the top right of the screen, move the mouse down and then clicking search), entering the network troubleshooterin the search box, type, or by clicking settingsand then by typing or clicking on identify and fix network problems.

    If the problem persists, try the following method.

    Method 2:

    Second of all, please check if the WLAN service is started and set to automatic. If it is stopped, then I suggest you to start the service and set it to automatic.

    1. Press the Windows key + R, type services.msc in the Run dialog box and press ENTER.
    2. Select the Autoconfiguration WLAN service in the list and double-click it.
    3. Change the startup to Automatic type, then click Start to start the service.
    4. Click apply and then click OK.
    5. Restart the computer and verify if the network is detected. If this is not the case, go to method 3.

    Method 3:

    Reset the DNS and TCP/IP settings.

    1. Press the Windows key + X, click prompt (Admin).
    2. Please enter the following commands and press ENTER after each one.

      netsh int ip reset resetlog.txt
      netsh winsock reset
      ipconfig/registerdns
      ipconfig/flushdns
      ipconfig/release

    3. Restart the computer to check the issue.

    Check if the system is able to detect the network. If this is not the case, go to method 4.

    Method 4:
    Temporarily disable the security software (if any), and check if it helps.

    Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do not disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network during the time that your antivirus software is disabled, your computer is vulnerable to attacks.

  • Unable to connect to Apple ID after upgrade to ElCapitan 10.11.5

    I have the Macbook Air 11 "1.4 Ghz i5 with 4 GB 1600 MHz DDR3 (early 2014)

    I can't connect to the Apple ID (iCloud, Appstore...) after upgrade in ElCapitan 10.11.5

    About 3 weeks ago I improve my OS in ElCapitan as there was a signal of the Appstore upgrade.

    The download process and the installation was successful, but stuck on 'prepare your mac' session. It took about 2 hours, with cursor processing... Then I closed (push the power button on the keyboard) and turn.

    My Mac can work and in "about this Mac" already made it known that the OS is ElCapitan 10.11.5.

    But unfortunately, since then, I can't sign my Apple ID in the Mac (I use several apple 'iphone', 'ipad' products and my apple ID still works)

    I came to the nearby authorized Apple service, they don't have that one solution to re - install my Mac and I have to pay

    Maybe someone has a solution...

    Hi atiqurrakhman,

    From the information provided, it appears that you are unable to connect to your Apple ID for several services on your Mac from your update of OS X El Capitan 10.11.5. I know it's very important to have access to these services on your Mac, then I would be happy to provide assistance.

    Before you start, I recommend that you create a backup of your data using Time Machine. This website will provide more information:

    Use Time Machine to back up or restore your Mac - Apple Support

    Since the update seems stuck, it can not been installed properly on your system. The next step, I would recommend that you reinstall OS X from recovery using the steps here:

    How to reinstall OS X on your Mac - Apple Support

    Reinstall OS X from recovery

    If a recent Mac, you can use OS X Recovery to reinstall OS X.

    1. Turn on your Mac.
    2. As soon as you hear the startup tone, hold down the command and R on your keyboard.
    3. Release the buttons after the appearance of the Apple logo.
    4. If you are prompted, select a Wi - Fi network, or connect your Mac to the Internet via an Ethernet cable.
    5. After that the recovery menu will appear, select the option to install OS X.
    6. Follow the prompts on the screen to select your destination drive and install OS X.

    Once this process is complete, try to sign in with your Apple ID using multiple services to see if the problem has been resolved.

    Have a great rest of your day!

  • EA6500 unable to connect to the router after Time Machine

    Just got an EA6500 - updated to the latest firmware available.

    I have attached 2 x WD NAS and 1 x WD through the USB port of the device.

    Each time after I finished running Time Machine on the MacBookPro (written to one of the WD NAS), I can no more connection to the router as neither the local IP, or the cisco connect cloud. The error message I get (loosely formulated) is: unable to connect to the router.

    Hey guys.

    OK not sure if anyone else has this problem, but I can't connect to my Airport Extreme update IOS 10 my wife is.

    We all have two iPhone 6 and 64 gb & update at the same time.

    We have an ac 802.11 Airport extreme also an extreme dual band of airport & an express airport which none of us can connect to.

    We can connect to the Home Hub 6 provided by our service provider broadband with no problems but it is only in a part of the House that we are unable to connect to my office or at the back of the House.

    Tried resetting the network settings on the phone thought I might ask before having to try to reset back to factory settings base stations.

    Thank you

    FWIW, I upgraded my iPhone SE 5 and Pro iPad to iOS 10 as well, but knows me not any problems connecting to one of my base station AirPort to Wi - Fi.

    Or the other of your iPhones must all problems connecting to other networks in addition to the Home Hub Wi - Fi? In other words, are they only having problems connecting to your AirPort base station? If Yes, do you have someone nearby who also has an AirPort wireless network that you should check your iPhones with?

    In the meantime, let's take a look at the current configuration of your network. We know that you, at least, three airport base stations. What is the exact models of non - 802.11ac extreme and Express?
