Set the error code for the exception qualified using the pragma exception_init

Hello

I did experiments on exception management in oracle plsql. In my experiments, I did the following anonymous plsql block.


+ < < outer_block > > +.
declare
+ exceptions.    +
Start
+ < < inner_block > > +.
+ State +.
+ exceptions.        +
+ start +.
+ recovery outer_block.exc +;
+ exception +.
+ What then outer_block.exc +.
+ dbms_output.put_line ("' outdoor Exception caught"); +
+ What then inner_block.exc +.
+ dbms_output.put_line ("'Inner Exception caught"); +
+ end; +
end;


When I run the code, I got the output "external Exception caught".

------------------------------------------------- PLSQL Block 2 -------------------------------------------

I changed the code a little differently by assigning exceptions error codes.

+ < < outer_block > > +.
declare
+ exception exc; +
+ pragma exception_init (exc,-20001); +
Start
+ < < inner_block > > +.
+ State +.
+ exception exc; +
+ pragma exception_init (exc,-20001); +
+ start +.
+ raise_application_error (-20001, "Error"); +
+ exception +.
+ What then outer_block.exc +.
+ dbms_output.put_line ("' outdoor Exception caught"); +
+ What then inner_block.exc +.
+ dbms_output.put_line ("'Inner Exception caught"); +
+ end; +
end;

When I run the above code, I got the following error.

Error on line 1
ORA-06550: line 15, column 9:
PLS-00484: exceptions redundant "EXC" and "EXC" must appear in the same exception handler
ORA-06550: line 5, column 1:
PL/SQL: Statement ignored

Script done on line 21.

------------------------------------------------- PLSQL Block 3 -------------------------------------------


To avoid this error, I changed the code again by qualifying exceptions with their block names. This time, I got a different error.

+ < < outer_block > > +.
declare
+ exception exc; +
+ pragma exception_init (outer_block.exc,-20001); +
Start
+ < < inner_block > > +.
+ State +.
+ exception exc; +
+ pragma exception_init (inner_block.exc,-20001); +
+ start +.
+ raise_application_error (-20001, "Error"); +
+ exception +.
+ What then outer_block.exc +.
+ dbms_output.put_line ("' outdoor Exception caught"); +
+ What then inner_block.exc +.
+ dbms_output.put_line ("'Inner Exception caught"); +
+ end; +
end;


Error on line 1
ORA-06550: line 4, column 38:
PLS-00103: encountered the symbol ". «» When expecting one of the following values:

), = >
The symbol"were replaced by". "to continue.
ORA-06550: line 9, column 42:

Question:
Pourraient several exceptions with the same name of the exception defined in the set of nested blocks plsql assign error codes using the pragma EXCEPTION_INIT? If there are errors in the PLSQL 2 blocks and 3, please suggest.
If the same thing could be accomplished by other methods, please explain.

The problem in your code block 2 is that you have not only used the same name of the exception, but you have assigned them with the same exception code. If the code is different so it will work...

Hello 4 keep screwing browsers and now I get connection network problems. I run Comcast doctor and did everything it said to do, but nothing works. Oh and I added 7-Zip and WinZip also.

    keimanzero,

    Comcast of Norton Security Suite version is installed? If Yes, who and perhaps malware is most likely to cause questions you have published, in particular the failure of the restoration of the system.
    First, configure the system to boot - How to solve a problem by performing a boot in Windows Vista or in Windows 7
    NOTE: Start-up mode minimum state all the 3rd party firewalls will be disabled. Open Control Panel > Windows Firewall to make sure that the native firewall of Windows 7 is now on.

    Download and Save the update system (or CheckSUR) tool. You will need to download the specific Version of CheckSUR corresponding to the architecture of the system to Windows 7. If you do not know the architecture of the system, and then click the link that says "Click here to show or hide the instructions step by step with images" under method 2: download the update directly system preparation tool from Microsoft Download Center .
    Description of the preparation tool system update for Windows Vista for Windows Server 2008, for Windows 7 and for Windows Server 2008 R2

    Once the download is complete, close all open programs and browsers. Now, run CheckSUR with the system connected to the internet because it will download the .cab for system files. Reboot once CheckSUR is complete.

    Secondly, I suggest that you run the File Checker system while in the same clean boot state.
    To run the System File Checker tool, follow these steps:

    1. Click Start and type cmd in the field search programs and files .
    2. Right click on cmd.exe in the programs of list, and then choose 'run as administrator '.
      If you are prompted for an administrator password or a confirmation, type your password or click on continue.
    3. At the command prompt, enter the following line exactly as written including the space between thec and the/and then press ENTER:
      sfc/scannow

    When the analysis is complete, test to see if the problems facing the system have been resolved.

    If they are not, you will need to contact Norton support for the version of Norton Internet Security Comcast to get help, or just uninstall NIS, run the Norton removal tool (right click Norton_Removal_Tool.exe, choose "Run as Administrator"), reboot and then check to see if the problems are still occurring.

  • Where can I get a list of the error codes for InDesign server

    I use InDesign server to the process that a lot of jobs and could not find a list of error codes generated by InDesign Server. Specifically, I'm looking for error codes generated in cases where the InDesign customer seem to have made a mistake. To give an analogy, the Apache HTTP Server generates class 4xx Code of the status each time the client seems to have erred. Is there a list of error codes similar for InDesign server.

    For example:, I wrote a work to convert .indd idml files and voluntarily gave a corrupt .indd file to convert. I got the following response code.

    Error code: 29441

    Error message: could not open the file "corrupt_file.indd". Adobe InDesign Server can not supported file format, a plug-in that supports the file format is may be missing, or the file may be open in another application.

    I couldn't find a reference to the error code 29441 in the Adobe documentation. All leads or references?

  • I do not receive an error code for updates failed

    original title: update seems to work and indicates successful but when I check some updated why some say failure and why does not receive an error code during the update process?

    Whenever I update the installation process says successful but when I went on a lot of my updates to display the details I see "failed." Why is not updating error messages instead of download the update and declaring that it was installed successfully? Why this is happening, seems I can't besure if my updates are actually loaded, even if each notes "installed successfully". I don't want to have to go thro each update to check its status.

    Hello

    By default, the Windows Update client records all transaction information in the following log file:

    %WINDIR%\WindowsUpdate.log

    If you receive an error message on the Microsoft Windows Update Web site or automatic
    Service updates, you can use the information in the Windowsupdate.log file to resolve the problem.

    Open the log file and search for the error codes. Post the logs here so that we can check what exactly is causing the problem.

    Hello

    You may need to format the USB key if the method in the lower section
    does not help. And it is possible, that there is a problem with the hardware with the reader.

    Format a Flash DRIVE with the NTFS file system
    http://www.pctipsbox.com/format-a-USB-drive-with-NTFS-file-system/

    ===========================

    This is the likely cause of your error:

    A USB can support only a very limited number of files and folders at the root
    Directory/folder. To resolve this are one or more folders and copy the files into it/them.

    H:\ if H: is the thumbdrive

    H:\Myfiles

    H:\Documents

    and so one and copy the files in these folders. You may need to remove a few files in a
    apparently a lot thumbdrive to create the folders.

    I hope this helps.
