cftry / cfcatch do not display error message

I'm trying to display an error message when a user selects incorrectly two elements. But the message does not appear. Please let me know what I am doing wrong. On the page of the form, the user selects couse them and types in their identification. If the ID and classes are not already in the same table in the database, they should then be invited to try again. Here is my code

< cftry >
< cfquery name = "all" datasource = "hr1" >
Select EMPLID, COURSE_TITLE
Training
WHERE EMPLID ='#FORM. EMPLOYID #'
And as COURSE_TITLE ' #FORM. CLASS #% '
< / cfquery >

< cfcatch type = "any" >
<!--> the message to display
< cfoutput > we do not show you enrolled in this course, please select another < / cfoutput >

< / cfcatch >
< / cftry >

Thanks for all the help. I found another solution in another forum. Since fails it to query is not complete a registration account. I had to go back to the CFTry and return the query. This code works-



Select EMPLID, COURSE_TITLE
Training
WHERE EMPLID ='#FORM. EMPLOYID #'
And as COURSE_TITLE ' #FORM. CLASS #% '




Then using the recordcount function it generates the correct answer



#form.employID # wishes to withdraw the course #COURSE_TITLE #.
You have chosen to cancel the registration of #COURSE_TITLE #. An email was sent to your supervisor.

Our records do not show whether you are enrolled in this course. Please select another.

  • A single application preventing the closure of the displayed error message...

    Hello

    When I closed my laptop, the displayed error message one application preventing closing down.

    as directed by your previous post, I have set up my laptop with it, but this problem yet and still occur.

    now the error message saying Windows host prevents your stop down.

    Please, help me to overcome this problem.

    Hi Regis,

    Thanks for posting your question on the Microsoft Community forums.

    I understand that you get the error message so that the closure of the system. However, I would like to know some more information on the issue to provide you with better assistance.

    1. Who is "previous post" you are talking about?
    2. What is the exact error message you get now on "Windows"host?
    3. You did it any significant hardware or change software on the computer before this problem?

    The question may arise if certain services (including background Windows services and other third-party application services) are still in operation when you try to shut down the computer.

    The applications or programs sometimes have ongoing services which are still ongoing even if you close your programs. Properties of an instance, there are many third party messengers that require you to sign in to use the application. Thus, when you close the application, the corresponding services are sometimes even functional whereby the program restarted in less time and log into the self-signed.

    Therefore, usually do not completely quit us some programs when we literally close them and so we get these guests. To diagnose the problem, you can restart the computer in safe mode when only minimal services are in use, you should not get these guests so that closing.

    If you do not get these guests in safe mode, you can also try to boot your system in a clean boot, a selective startup in the third that most of the services are disabled. To do this, you can consult the following link:

    How to perform a clean boot in Windows

    Note: See "how to reset the computer to start normally after a boot minimum troubleshooting" to prepare the computer to start as usual after a repair.

    Hope this information is useful. Let us know if you need additional help on the issue, we will be happy to help you.

  • Application not found Error Messages

    Application not found error message Hi,.

    I recently had a virus on my Windows XP which I removed with Norton Internet Security.  The virus was called "XP Antispyware 2010".  After that I took it with the version of Norton Internet Security 2010 newly installed, I realize that I could not access the internet directly by clicking on the icon. a window will open asking for me to choose the program I want to use to open IE.  He would then run the program but nothing happens and it goes in circles asking to select a program to open, run, etc.

    Soon I noticed that clicking on other applications would result in an error message saying "Application not found".  I can't remove programs from my control panel because it is inaccessible, I can't open Microsoft Office programs directly unless I go to my computer.  I can't do a system recovery or restoration; the same messages will pop up. So basically, I can't make any changes to my laptop programs or access directly.  Help, please.

    I called Symantec who tried to help.  Norton Internet Security has been removed from my laptop, but I still have the same problems.  I was then told that this isn't a problem with Norton, but with Windows and the file sharing/accessibility.

    Help, please.

    Thank you

    Hi, Debbie.

    First of all, Norton is not the choice of the antivirus, I recommend, and I seriously doubt that he removed all, if any, elements of Xp Antispyware 2012. Their support is not much better that you will probably notice now.

    The errors that you receive are obviously the result of the malware.

    We will try to solve your problems one at a time.

    Using another computer, and then transfer the files to the computer in question via revovable storage like a disk or flash/thumb drive click HERE. Download the file. Extract the contents of the zip file.

    Click HERE and download another zip file, extract the contents again.

    Right-click on the files one at a time of course and choose "merge". Confirm guests. You should now be able to open your shortcuts and executable files.

    Click HERE. Download Malwarebytes. Update Malwarebytes and perform a scan.  Choose whether to remove anything found. Once completed click HERE and download Superantispyware Portable. Perform a quick scan again remove anything found.

  • HP 5535 won't scanner, printer not found error message

    I have a HP Envy 5535. I've only been able to scan with it once. I scanned 22 documents, after HP Scan Doc 4.4 running. Every time the scanning HP Doc says everything is OK, but as soon as I try to do an analysis of test, I get the error message "printer not found." I also tried this scanner with my McAfee virus firewall off the coast, and it still does not work. I have also identified it on McAfee as part of my network.

    Welcome to the HP Forums!

    I'm sorry that you can not scan with your HP Envy 5535, but I'm happy to help you!

    4. If the power cable is connected to a surge protector, or directly to a wall outlet. Questions when it is connected to an uninterruptible power supply/Strip/surge protector power. This is true for printers and ink jet.

  • Raise_application_error displaying error message not personalized

    I'm quite new to PL/SQL, and I have a problem with the display of my exceptions that I can't understand.

    I use two stored procedures and anonymous block to call them. I did some other procedures in this way and they all work very well.

    It is the first procedure that updates my table.

    create or replace procedure UPD_CUST_SALESYTD_IN_DB (pcustid number, pamt number) AS 
    err_pamt exception
    ;
    err_pcustid exception
    ;
    vcount number
    ;
    begin
    select count(*) into vcount from customer where custid = pcustid; 

    if vcount = 0 then raise err_pcustid;
    end if; 

    if pamt <-999.99 or pamt >999.99 then raise err_pamt;
    end if; 

    update customer set sales_ytd = sales_ytd + pamt
    where custid = pcustid; 

    exception
    when err_pcustid then
    RAISE_APPLICATION_ERROR
    (-20031, 'Customer ID not found');
    when err_pamt then
    RAISE_APPLICATION_ERROR
    (-20032, 'Amount out of range');
    when others then
    RAISE_APPLICATION_ERROR
    (-20000, SQLERRM);
    end; 

    It is the procedure that calls the procedure above. It shows just what I'll do and confirms that it worked.

    create or replace procedure UPD_CUST_SALESYTD_VIASQLDEV (pcustid number, pamt number) AS 
    begin
    dbms_output
    .put_line('--------------------------------------------');
    dbms_output
    .put_line('Updating SalesYTD. Customer Id: ' || pcustid || ' Amount: ' || pamt);
    UPD_CUST_SALESYTD_IN_DB
    (pcustid, pamt);
    commit;
    dbms_output
    .put_line('Udpate OK');

    exception
    when others then
    RAISE_APPLICATION_ERROR
    (-20000, SQLERRM);
    end;

    It is the anonymous block to call the procedure above, which then calls one I use.

    set serveroutput on; 
    begin
    UPD_CUST_SALESYTD_VIASQLDEV
    (3,999.9);
    end;

    If I pass parameters which would not give me an error, the code works fine.

    For example, if I input;

    set serveroutput on; 
    begin
    upd_cust_salesytd_viasqldev
    (3,400);
    end;

    I get the correct result and made the changes in the table.

    -------------------------------------------- 
    Updating SalesYTD
    . Customer Id: 3 Amount: 400
    Udpate OK

    However, if I pass parameters that would result in an error, or a customer id doesn't exist does not, either the amount being out of reach, nothing happens. I get this:

    -------------------------------------------- 
    Updating SalesYTD
    . Customer Id: 3 Amount: 1000

    Nothing else.

    In similar procedures my exceptions work very well. This example uses a procedure that inserts into a table.

    -------------------------------------------- 
    Adding Customer
    . ID: 500  Name: Helen Nolan
    ORA-20002
    : Customer ID out of range

    I don't know why this procedure is not at all my exceptions. In my other procedures that work, if an exception is thrown, the right output script in Oracle SQL Developer displays my exception.

    However, in my update procedure, if something should trigger an exception, over the lines of DBMS output, the output of the script prints this error report

    Error report - 
    ORA-20000
    : ORA-20032: Amount out of range ORA-06512:

    *Cause:  The stored procedure 'raise_application_error' was called which causes this error to be generated.
    *Action:  Correct the problem as described in the error message or contact the application administrator or DBA for more information.

    So he is grateful he my exception was raised, but it has not been demonstrated.

    Any help is greatly appreciated, I am completely confused by this. I have a really obvious mistake?

    Your logic and exception management is wrong.

    (a) make a count to determine the existence of a record prior to an update on this subject is wrong.  If the record is deleted by another user inbetween you your county and the update, then you can try and update a record that no longer exists.

    (b) while other exceptions are to be avoided - only handle exceptions, you expect to be raised.

    (c) update a record will set the SQL % ROWCOUNT pseudo variable, which should be checked immediately after the statement and used to determine if the record exists or not...

    create or replace procedure UPD_CUST_SALESYTD_IN_DB (number pcustid, number of ALMPs) AS
    err_pamt exception;
    err_pcustid exception;
    Start
    If abs (ALMPs) > 999.99 then
    raise err_pamt;
    end if;

    customer update
    Set sales_ytd = sales_ytd + ALMPs
    where custid = pcustid;

    If rowcount % sql = 0 then
    raise err_pcustid;
    exception
    / * Business Logic Exceptions * /.
    When err_pcustid then
    RAISE_APPLICATION_ERROR (-20031, "Customer ID not found");
