HO to handle errors in procedures or the my caller PKG

Dear all
I have a small doubt...
How can I handle errors in my appeal procedure or PKG?
Means:-J' have a procedure as follows: -.

Create or replace procedure P1( iempno number,oname out Varchar2)
IS
Begin 
 Select empname into oname }
 From emp 
Where empno = iempno ;
Exception 
 When no_data_found then
  Dbms_output,put_line (SQLCODE||’-‘||SQLERRM);
END;

IF I call this in my PACKAGE so how to catch this error in my package? I mean if errors happens here in this procedure, then it should disply when I will exercise the PKG.
So what I did is right or not?

And in the same way, I have a PKG. I call this PKG in my trigger of FORM button press...
SO for the exception what should I write?
Let's say in my package, I have a proc and ther that I wanted to write when no. _data found so...
Dbms_output, put_line (SQLCODE |) » -‘|| SQLERRM);
Raise_application_error ("-20000', 'ABC'");

Which is correct?

Kindly guide me how handle errors by calling pkg proc or functions...

Hello
You will need to use RAISE_APPLICATION_ERROR if you want to view the message in your form by the package/procedure/function of the database.

Error in your procedure/package/service write the statement as below...

RAISE_APPLICATION_ERROR('-20000','Error Message Goes Here...');

Now in the form create trigger on called-ERROR at the level of the form, and view the message using the variables DBMS_ERROR_CODE and DBMS_ERROR_TEXT.

Error when painting during the AJAX call page fault
Hi all

I do a simple AJAX call test with the emp table. In my page, I have a report, a search box and a button. You put in a text and click search and you will get the result that all the works.

I have a requirement where if you click on the button and there is no search match you will be redirected to another page, just reload the report to display the result as usual.

So, I took the road to AJAX where I perform a simultaneous when the user enters a text search and click on the button. If the search count (*) > 0 then return return County else returns 0.

The code for the application process is:
```
DECLARE
begin
CCOUNT number;



begin
Select count(*) into ccount 
from emp
WHERE 
UPPER(:F_SEARCH_RESULT) like '%'||upper(ename)||'%';

exception when no_data_found then
htp.p(0);
end;

htp.p(ccount);


END;
```
My (still working on that) Java script code is:
```
<script language="JavaScript" type="text/javascript">


     function search_count()

     var get = new htmldb_Get(null,null,'APPLICATION_PROCESS=SEARCH',0);
     get.add('F_SEARCH_RESULT', $v('P1_ENAME'));
     var gReturn = get.get();     
     console.log(gReturn);

     var gReturn_sanitised = praseFloat(gReturn);
          if (gReturn_sanitised == 1)
          doSubmit('SUBMIT');
     
          
</script>
```
I tested this code in Firebug, and when I do a console.log (gReturn) on the release of the AJax call I get this error that prevents me from dealing with the result of gReturn and be done with the code. The error looks like:
```
<html><body>
<h1>Error occurred while painting error page: ORA-01403: no data found</h1>
</body></html>
```
I tried adding exception when no_data_found but without success. Still get the same error. My version of the APEX is 4.2, any suggestion welcome. See you soon.

Still no luck, even if I'm doing a simple:

in the process of the page, I get the same error as before.

I've done much AJAX call like this before elsewhere and can't for the life of find me whats wrong here.

Error-2625 cannot write the file call node in NI_XML.lvlib:Save.vi

I get this error when you perform a certain acquisition with a CoolSnap HQ2. The user defines its parameters, then these settings are saved in the file so that they can be easily identified later in the database. The error came to us when we did a test with 4 different parameters. We did: Laser X w / filter X; Laser X w / filter Y. Laser Y w / filter X; Laser Y w / filter Y.

The first and the third is saved without errors, but the second and fourth receive errors.

Error-2625 cannot write file call node in NI_XML.lvlibave.vi

Someone has an idea, what happens? This is the vi I'm talking about.

I forgot to mention that the name of filter attribute is 593/LP, could the "/" be the cause?

Found the solution. It is indeed the "/" in the name of the filter that caused the problem. I replaced it with a '-' and everything worked

I get the context menu after using firfox as my browser: Exc in ev handl: error: Bad NPObject as private data!

In the last few days I've been doing the following popup when I use firefox as my browser: Exc in ev handl: error: Bad NPObject as private data!

I guess it comes from your last update. I have windows vista with a 64-bit processor, and I use the latest version of firefox. I checked to see if I was getting the same error message with explore and I'm not. It seems to be some sort of conflict with java script. This can be corrected?

You have to remove and re - install anything. I had the same problem and simply disabled the McAfee Siteadvisor module without deleting. I then restarted Firefox and the problem was solved.

But here's the important part: I reactivated the add-on and then restarted Firefox twice. The problem is not returned!

Just so disable, reboot, re-enable and restart. It worked for me!

Satellite A100-153: Error Message appears during the recovery procedure

Windows - delayed write failed
Windows was unable to save all the data for the file\Device\Harddisk\volume2\I386\OEMBIOS. Bl_. The data has been lost.
This error can be caused by a failure of your computer hardware connection or a network. Please try to save this file elsewhere.

So I don't know what to do...
Is the problem that my hard drive is broken? but I don't think, because when I install with Windows XP Home Edition OEM I come up to 91% and then comes another error :((

Please help me, anyone know what I can do?

Please answer quickly... I need my phone tomorrow :*(

Welcome, Tobias Erdmann

Hello

I guess you have you used original restore CD that was shipped with this laptop. That's why I put t thinks it is a CD problem but maybe with your HARD drive.
Have you tried to format the whole HARD drive? Delete all partitions and format the HARD drive before installation

If the OS install will not work or will divide in the middle of the procedure, then the material should be checked. The A100 is not very old unit and therefore the guarantee must be valid. If a new HARD drive is necessary you should get it for free.

Good luck and please post if you know more details

Re: "insufficient privileges" error when you run the Java stored procedure in another schema

I get an "insufficient privileges" error when you run the Java stored procedure in another schema, see details below. I don't know what are missing privileges (I already granted the EXECUTE privilege), suggestions? -Thank you.
Define a simple java class and deploy it as a Java stored procedure to test:

Schema: User1
test of the package;
public class HelloWorld {}
public HelloWorld() {
Super();
}
public static String Hello () {}
Return "HELLO";
}
}
CREATE or REPLACE FUNCTION HELLO RETURN VARCHAR2 AUTHID CURRENT_USER AS LANGUAGE JAVA NAME ' test. HelloWorld.hello () return java.lang.String';
Grant execute on USER2 HELLO
Test the Java stored procedure through the PL/SQL function call (in the same schema):

Schema: User1
SET SERVEROUTPUT ON
DECLARE
v_Return VARCHAR2 (200);
BEGIN
v_Return: = User1. HELLO;
DBMS_OUTPUT. Put_line ('v_Return =' | v_Return);
END;
anonymous block filled
v_Return = HELLO
Test the Java stored procedure through the PL/SQL function call in a different pattern:

Schema: USER2
SET SERVEROUTPUT ON
DECLARE
v_Return VARCHAR2 (200);
BEGIN
v_Return: = User1. HELLO;
DBMS_OUTPUT. Put_line ('v_Return =' | v_Return);
END;

You have created the function with AUTHID CURRENT_USER, which means that the function is executed with the rights of the applicant (but not with the rights of the author). This means that the applicant must have grants (directly or through roles) on all used/accessible objects in the service. In your case the user USER2 has not granted with EXECUTE on the class/source Java test. Class HelloWorld, causing the ORA-01031 exception. You create service without AUTHID CURRENT_USER (i.e. with AUTHID DEFINE, which is by default, if you do not have a specific reason to use AUTHID CURRENT_USER) or grant EXECUTE on JAVA test SOURCE. Class HelloWorld to User2.

403 Forbidden error of execution of the procedures of the URL of the browser stored
I am currently trying to run a simple stored procedure (ea.hello_world, where "ea" is the pattern and "hello_world" is the name of the procedure) a URL from the browser, but am getting a 403 Forbidden - error message "you don't have permission to access /pls/apex/ea.hello_world on this server. I use APEX 3.2 with Oracle 11 g and mod_plsql and gave the steps of apex_public_user. Any thoughts on what I am doing wrong?

Here is the process I have used so far:

Create the "Hello_World" procedure in the "EA: schema

create or replace
procedure hello_world
is
Start
HTP. Print ("'Hello World!");
end;

I then successfully granted to run the apex_public_user procedure:

Grant execute on ea.hello_world to apex_public_user;

Then, I tried to call the stored procedure from the browser using the following syntax:

http:// < Server >: < port > / pls/apex/< schema >. < Procedure & gt;

I also experimented with the use of a public synonym and the configuration of the wwv_flow_epg_include_mod_local, but I do not think that the function s relevant since I'm using mod_plsql and not the embedded pl/sql gateway.
Hello

If you have below the line in dads.conf, then wwv_flow_epg_include_mod_local sets
```
PlsqlRequestValidationFunction wwv_flow_epg_include_modules.authorize
```
Try:
Create public synonym
```
CREATE PUBLIC SYNONYM hello_world FOR ea.hello_world;
```
Grant privilege to execute procedure to the public
```
GRANT execute on hello_world to public;
```
Then change the APEX_030200.wwv_flow_epg_include_mod_local function
```
CREATE OR REPLACE FUNCTION
APEX_030200.wwv_flow_epg_include_mod_local(
    PROCEDURE_NAME IN VARCHAR2)
RETURN BOOLEAN
IS
BEGIN  

    IF UPPER(procedure_name) IN (
          UPPER('hello_world'))
   THEN
        RETURN TRUE;
    ELSE
        RETURN FALSE;
    END IF;
END;
/
```
Then try
http://:/pls/apex/hello_world

If you can now run your procedure in URL, you can then low and e.g. grant execute procedure to the user of DAD.

Hello

AppleSyncNotifier.exe is part of ITunes. To resolve the issue, try the following methods.

Method 1:

I suggest that you download and reinstall ITunes since this link provided below to fix the problem.

http://www.Apple.com/downloads/

Method 2:

You can perform the clean boot in order to eliminate the problem.

Put your boot system helps determine if third-party applications or startup items are causing the problem. If so, you need to maybe contact the manufacturer of the program for updates or uninstall and reinstall the program.

See the following article in the Microsoft KB for more information on how to solve a problem by performing a clean boot in Windows Vista or Windows 7:

How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

http://support.Microsoft.com/kb/929135

Note:

After troubleshooting, be sure to set the computer to start as usual as mentioned in step 7 in the above article.

For further assistance, you can get in touch with support for ITunes.

and then the statement of the problem and the solution for Site Advisor.

Firefox does not start and this message keeps coming back... I uninstalled and reinstalled... but nothing helped...

EXC in ev handl: error: error definition property on NPObject!

Disable the extension "McAfee Site Advisor" who has just updated 3.4.0 that probably out of block of addons list.
- 'Ctrl + Shift + A' > find McAfee Site Advisor and use 'Disable', and then restart Firefox.
- Do a Google search without problem
- It seems that if you re - enable new Site Advisor and restart Firefox you agree. At least you know where to look if you get the error again, or research on Google to slow down.
