Hi,
I made the mistake here
INSERT INTO TEST1(id,name) VALUES (0,:NEW.TEST_NAME);
where i defined the id as primary key.
But the another problem for me now is while compiling the trigger after i modified,
i get this error
11:37:05 Error: TRIGGER DB_TEST.TRG_EXCEP
On line: 7
PLS-00553: character set name is not recognized
Please help.
Thanks,

You can not use set_nls to change this parameter, you need 'execute immediate 'alter system... etc'
And it is a bad hack to work around not using bind variables.

Senior Oracle DBAalso a work around for when your system's parameter is set to 'SIMILAR' but you're trying to use certain XML functionality:

Validation returns : no data found + unhandled user-defined exception

Hi, I'm working with Application Express 4.1.1.00.23.
I have an application for timesheet management.
On one page, I've got a report (not interactive) in which you can enter the hours you've worked. First you add a free line, choose the task and then enter the hours you've spent.
You can only have one empty line at a time. If you try to add a line when you already have an empty line, a validation will display an error. It worked fine in version 3.2. Now we upgraded to 4.1 and get a weird error :
1) The validation msg appears fine
2) The report appears fine
3) There is a msg at the end of the report saying :
report error:
ORA-01403: no data found
ORA-06510: PL/SQL: unhandled user-defined exception
Could somebody point out the source of this problem ?
Thank you!

Hi, thanks for your answer. Here is the validation we are executing. I'm pretty sure its fine since count(*) always return a value (plus we see V2 in the debug...) :

Trapping user defined exceptions in forms

hi guys..
i have a database trigger that goes like that:
CREATE OR REPLACE TRIGGER loan_trig
before insert on loans
for each row
declare
lcount number(10);
duplicate_loan exception;
begin
select count(1) into lcount from loans
where branch_code=:new.branch_code
and client_code=:new.client_code;
if lcount>0 then
raise duplicate_loan;
end if;
end;
now how do i trap this user defined exception on the form ?
declaring the exception in the form & handling it in the exeption handler section doesn't seem to work and i get the following error:
"when button pressed trigger raised unhandled exception
ora-06510"
ora-06510:unhandled user-defined exception
what am i doing wrong?
if i have to handle the exception in the trigger body how do i do that?
thankx in advance..

Hello,
raise duplicate_loan; won't avoid the trigger to insert and commit. If you really want to avoid the insertion, use the raise_applicatrion_error() instead.
For instance : Raise_Application_Error( -20001, 'Insertion cannot be validated' );Then in your Forms module, you can catch it like this:
   Begin
   Insert Into ...
   when others then
      LC$Erreur := Substr( SQLERRM,1 , 500 );
      LN$err_code := ABS(SQLCODE);
      If LN$err_code = 20001 Then ...
   End;

How to handle user defined exception from C#?

Hi:
I have some PL/SQL code that will throw a user defined exception if certain conditions are met. How do I handle user defined exceptions if this procedure/function is being called from C#? C# can handle a normal Oracle SQL error (e.g. ORA-XXXX) because they are defined in the proper class, but how do I get it to know about my user defined exception? Does anyone have any links to examples of doing this?
Thanks.

Hi Gaff,
Is there a particular problem you're having doing this? It works as normal for me...
Cheers

I am using Portal 3.0.6 in Sun SunOS 5.8. The site will be running in https mode. As everybody knows, 443 is the default port number for ssl mode. I setup the httpd.conf to 443. No problem. I ran ssodatan to relate Login Server to Portal - I had to specify 443 at the end of URL in ssodatan syntax. Otherwise, I got "Error:You cannot login because there is no configuration information stored in the enabler configuration table. (WWC-41439)" both in Netscape navigator and MS Internet Explorer.
I now am able to log in Portal site. But, the problem happens just after loggin in. With Navigator I don't get any problems. But, IE gives me "Error: Unexpected error encountered in wwsec_app_priv.process_signon (User-Defined Exception) (WWC-41417)". I guess this happens because of how IE works with https. It takes 443 off from URL in https mode. The portal is unable to match the url and what it has in wwsec_enabler_config_info$ which has 443. When I tested with 444 as port number. It worked! Putting a port number in URL will be cumbersome. That's why I am trying with 443.
I tried also with ssodatax to add an additional entry for without 443 as specified in a document "Oracle9ias Portal configuration options" page 30. Ssodatax has a bug so it updates existing entry, too. I had to update it back to its original value. It's fine. But, this time another error comes up. "WWC-00000". I don't see any solution for this.

When a new user is logging on for the first time, the portal adds them to the AUTHENTICATED_USERS group under the portal's group container. In your case, for some users, this is apparently running into some problem.
To debug this, try turning on additional logging on the OID server and attempt logging in as these users, and see what is reported.
You should enable the following debug flags:
Search Filter Processing
Access Control List Processing
Status Log Connections/Operations/Results

"user defined exception" in a stored procedure and APEX

I would like to use user defined exception in a stored procedure or trigger in a APEX application.
Does anybody know how to do it ? or know where can I find a good reference ?
Thanks,

How to use user defined exception class

Hi all
I just need som help with creating a user defined exception class.
Im writing a small/simple text editor.
My exception class looks like this:
public class myExcp extends Throwable
     private String message;
     public myExcep(String message)
          this.message = message;
     public void display()
          System.out.println(message);
I would like to use it when a user tries to open a exe-file instead of a txt file.
Here is some code from the editor:
if (e.getSource() == open)
saveOld();
if (fc.showOpenDialog(null)== JFileChooser.APPROVE_OPTION)
readFile(fc.getSelectedFile().getAbsolutePath());
saveas.setEnabled(true);
So, should I use exception here or at the readFile method?
readfile:
private void readFile(String fileName)
try
String tmp = fileName.substring(fileName.length() -4, fileName.length());
if (!tmp.equals(".exe"))
FileReader r = new FileReader(fileName);
textarea.read(r, null);
r.close();
currentFile = fileName;
label.setText(currentFile);
changed = false;
catch (IOException e)
JOptionPane.showMessageDialog (this, "Cannot find the file " + fileName);
Where and how do I use my exception class.
Do I need to create an instance? Where?
Should the exception class extend Exception instead?
Thank you in advance /

Extend Exception, not Throwable. It's a checked exception that way.
Follow the Sun coding standards and make that exception class name start with a capital letter.
When you extend Exception, override all four ctors.
What's that display method you added? Isn't getMessage() good enough?
You need to create a new instance just before you throw the exception, of course.
Sounds like a terrible design, by the way. Exceptions shouldn't be used like "go to" for app logic. They should signal unrecoverable conditions. You can easily recover from the situation you've described simply by displaying a pop-up that tells the user to open only text-readable file types. I think that's a better solution.

PL/SQL Using SQL%NOTFOUND to raise a user defined exception in a function

I have written the following function for finding the number of items in stock in the item table.
CREATE OR REPLACE function getAmount (ItemID IN NUMBER)
RETURN NUMBER
AS
invalid_id EXCEPTION;
returnedQty number;
BEGIN
Select qty
Into returnedQty
From item
Where itemNo = ItemID;
RETURN (returnedQty);
IF SQL%NOTFOUND THEN
RAISE invalid_id;
END IF;
COMMIT;
Exception
WHEN invalid_id THEN
DBMS_OUTPUT.PUT_LINE('Invalid ID entered');
END getAmount;
The function compiles successfully, although there is a problem that Oracle is not handling my user-defined exception invalid_id
If I use the following for a valid itemID:
DECLARE
return_value number;
BEGIN
return_value := getAmount(1);
DBMS_OUTPUT.PUT_LINE (return_value);
END;
then the function returns the quantity of items in stock correctly.
However, if I enter an incorrect itemID, say 20
DECLARE
return_value number;
BEGIN
return_value := getAmount(20);
DBMS_OUTPUT.PUT_LINE (return_value);
END;
The invalid_id exception is not raised, and the Oracle errors says: no_data_found and the function has not returned a value. If I add a no_data_found exception, this works perfectly, but for this assignment I must write my own user-defined error.
Any help would be very much appreciated!
Thank you.

What you're trying to do, is to use an implicit cursor. Implicit cursors will raise no_data_found and too_many_rows in case of an error. Explicit cursors will not.
Also, you have a small coding error ... a little rewrite and your code will do as you want to:
CREATE OR REPLACE function getAmount (ItemID IN NUMBER)
RETURN NUMBER
AS
invalid_id EXCEPTION;
returnedQty number;
cursor citem is
Select qty
From item
Where itemNo = ItemID;
fnd boolean;
BEGIN
open citem;
fetch citem Into returnedQty;
fnd := citem%found;
close citem;
if fnd then
RETURN (returnedQty);
else
RAISE invalid_id;
END IF;
/* Do not catch your own exception or the calling code will not receive it.
Exception
WHEN invalid_id THEN
DBMS_OUTPUT.PUT_LINE('Invalid ID entered');
END getAmount;
Your problem is, you're not using a package. This means, that the calling code has no way of catching this user-defined exeption. The correct way is to define a package, define the userdefined exception in the package and refer to it in your code:
create or replace package amt
is
invalid_id EXCEPTION;
function getAmount (ItemID IN NUMBER)
RETURN NUMBER;
end;
create or replace package body amt
is
function getAmount (ItemID IN NUMBER)
RETURN NUMBER
AS
returnedQty number;
cursor citem is
Select qty
From item
Where itemNo = ItemID;
fnd boolean;
BEGIN
open citem;
fetch citem Into returnedQty;
fnd := citem%found;
close citem;
if fnd then
RETURN (returnedQty);
else
RAISE invalid_id;
END IF;
end;
end; -- end package
To do a simple test, you'll do:
declare
a number;
begin
a := amt.getAmount(123);
dbms_output.put_line('The result is '||a);
exception
when amt.invalid_id then
dbms_output.put_line('ID not found');
end;
Other ways is to raise the exception in your no_data_found block.
But I'm REALLY puzzled if there's really someone out there who prefers a user-defined exception instead of the clearly defined NO_DATA_FOUND exception.
I can't be sure of course, but are you sure what they mean is they don't want ANY exception? That's a pretty common requirement.
In general - explicit cursors are a bit faster because Oracle does not have to do a second fetch to determine TOO_MANY_ROWS. And it's not too much additional writing. Explicit cursors will never raise exceptions - unless you use dynamic sql and your SQL is invalid.
Good luck

In which of the following sections of a PL/SQL block is a user-defined exception raised?

Hi,
A (somewhat elementary) question:
In which of the following sections of a PL/SQL block is a user-defined exception raised?
a) Exception section
b) Declarative section
c) Error handling section
d) Executable section
I'd be interested to hear people's answers.
Thanks.

As Etbin already noted, there are only 3 sections and user-defined exception can be raised in any of them. User-defined exception raised in declarative section example:
declare
    year_zero exception;
    pragma exception_init(year_zero,-01841);
begin
    declare
        v_dt date := to_date(1721420,'j');
    begin
        null;
    end;
exception
    when year_zero
      then
        dbms_output.put_line('Year 0!');
end;
Year 0!
