Ora-06502 pl/sql numeric or value error in Report Query in oracle apex

Hello all,
I need your help...
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
I am using bi publisher to generate PDF reports in oracle apex.
We were using APEX 4.0 and migrated to 4.2 just a week ago.
Now we have apex 4.2.
When I try to Create report query,
Shared Components >> Report Queries then create.
and test a report in a create wizard I am getting a error "ORA-06502: PL/SQL: numeric or value error: character string buffer too small".
I have also applied a patch "16760897".
This issue is because of number of columns in a query is more then 26.
If I run a report with 26 or less number of columns then the is working fine, otherwise getting this error.
My before migration report queries working perfectly even now, but not new queries.
This issue is also in apex.oracle.com.
You can see
Not working - http://apex.oracle.com/pls/apex/f?p=619:4
Working - http://apex.oracle.com/pls/apex/f?p=619:2:
Please give a solution.
Thanks you.

check the DB version compatibility with apex 4 or your DB version to apex 4.0 support for upgrade!

How fetch data from a view(which is located in different server) using Oracle APEX webservices

Hi,
I have a requirement to fetch the view data from client instance(which is different server) to another instance lets say Development instance
Requirement:
Need to get the Apps View data from the Desired EBS instance(which is accessible online) using webservices,and display it in the Oracle Apex Development Instance.
Kindly provide your inputs how to achieve this.
Thanks in advance

Are you getting an error? The way you have it set up, you can have an error and it will never be displayed. Put and error control on your front panel and see what it gives you. Also, shared variables in a project can be useful. Look at some examples for that.

Getting error while importing the application in Oracle Apex

Hi,
I am facing an issue while importing an application into my new Oracle Apex installation. Installation was successful with out any issue. I exported an application from my old Apex (version 3.0.0.00.20) and importing the same into new apex (version 3.0.1.00.08). I am getting the following error.
============================================================
The requested URL /pls/apex/wwv_flow.accept was not found on this server.
============================================================
When I click on import in Application Builder page and then browse the required file it gives the progress saying "Importing File" and after some time it displays the above error.
I tried bouncing the application also and there is not error in alert log.
Could any one please suggest, if there is some problem here. Or my approach is not correct.
Thanks in advance.
Regards,
Advait Deo

Osacar, I recommend that you try to import the application into your workspace on apex.oracle.com and see what happens. Also, refine the problem statement as much as you can, e.g., you get this error importing "the application" or when importing "any" application. How big is the file you're trying to import? Where did it come from? Can you upload images?

Does anyone have any solution how to escape the single quotes in Oracle APEX 4.2. - like \' or something? I already tried using backslash but had no luck.
Would really appreciate your help ASAP.
Thanks,

execute immediate 'update emp set sal = sal * 1.2 where ename = ''SCOTT''';However a better approach when dealing with SQL strings is to use the alternative quoting mechanism:
execute immediate q'{update emp set sal = sal * 1.2 where ename = 'SCOTT'}';as this allows the original string to be left unaltered.

Apply "WHERE CONDITION" in "MASTER/DETAIL FORM" in "ORACLE APEX

Hi to all respected Gurus of this community.
I have a problem and I hope that there must be solution in this community and I am not aware of that till now.
I have a master/detail form in Oracle Application Express. Now, I want to apply a where condition in master-form to filter the data as per requirement but I cannot do so.
There is an option of "Modify Query" in "Query Definition". According to the instructions I am selecting the desired column (HR_Category) in left and providing text string 'M-9' in the right column to filter the data where HR_Category is M-9, and when I press apply changes, it gives me an error that
"1 error has occurred
The condition you are adding has caused the query to be invalid."
Please help how to proceed to apply a where condition.

Probably a syntax error. Check the syntax of the new clause very carefully.
Can you post the query indicating which predicate is the new one? If you need to change the column and table names for confidentiality

Integration of Oracle Apex with EBS R12.1.1

Dear All,
We are in process of integrating Oracle Apex 4.0.2 with EBS R12.1.1 with the help of http://www.oracle.com/technetwork/developer-tools/apex/apex-ebs-wp-cabot-consulting-169064.pdf.
After doing all the steps, the moment when we navigate from EBS application to Apex application by clicking on the EBS menu link it ends up with below error
"404 Not Found
Resource /OA_HTML/null/pls/apex/f not found on this server"
After some analysis i found the below code in "LaunchApex.jsp" for getting the profile value (supposed to be 'http://myserver:port') from custom system profile "APEX_HTTP_SERVER" and prefixing to "/apex/f?p=applicationid:page::APPS:::" is not happening properly
String l_launcher = ctx.getProfileStore().getProfile("APEX_HTTP_SERVER");
l_launcher = l_launcher + "/apex/f?p=" + p_application + ":" + p_page;
l_launcher = l_launcher + "::APPS:::" + p_item_names + ":" + p_item_values;
as we found that the custom system profile "APEX_HTTP_SERVER" not exist in EBS system. But it works without any page error if we hard code the entire apex application URL in l_launcher variable, but this takes us to EBS login page instead of Apex application page.
So i feel we can't bypass using profile value from "APEX_HTTP_SERVER" as it has some relation with EBS application session.
So could anyone please help me how we could create custom system profile "APEX_HTTP_SERVER" or any other options to make the seamless integration of Oracle apex with EBS works without any second login page
Thanks in advance

Hi,
Create a profile under Application Developer Responsibility as follow:
Name OAE_LAUNCHER
Application <whatever>
User Profile Name Oracle Application Express Launcher
Description Oracle Application Express Launcher
2. Set above profile value under System Administrator Responsibility -> Profile -> System, and search for the ‘OAE_LAUNCHER’.
Set the value at Site Level as:
http://<hostname>:<Apex port>/pls/apex
Then instead of hardcoding the URL in the jsp, just give the profile name OAE_LAUNCHER that you have just created in the jsp.
Hope this helps you

Reading and Updating MS Active Directory (AD) through Oracle APEX

Hi All,
Has anyone ever read and update the AD components using Oracle APEX?
I know we can have APEX build in LDAP Authentication, but that is for the Authentication, what about reading other attributes like phone no., department, office etc. from MS AD; and about updating the same information.
Is Oracle Identity Management the only solution?
Windows 2008 R2 Server provide SOAP based AD web services (ADWS), has anyone used that with APEX (11g R2 with EPG configuration)?
Is it possible to have a C# code (through external procedure) which could read and write MS AD; can we use only "C" code in oracle as external proc or C# as well?
Any pointers would be of great help.
Thanks,
Ash

Ash,
It's possible to query data from the LDAP server, but it's not as easy as you'd like. I don't know about updating, but fopr querying, you're looking at creating a package using DBMS_LDAP and a pipelined function to get the data. Here's one example from a quick google search; there are others.
One thing to be aware of that burned me: the default LDAP setting limits requests to 1,000 records. If your search gives more than that, you get an error (and no data at all). So you may find yourself having to use unions to get the full data, which slows things down a bit.

Hi Mike,
Thanks for your reply, Let me give you a detail on where we are stuck on send mail.
   We have a Schema called PORTAL
We are able to send mail from UTL_SMTP as mentioned below in a procedure
create or replace PROCEDURE send_mail (p_to        IN VARCHAR2,
                                       p_from      IN VARCHAR2,
                                       p_message   IN VARCHAR2,
                                       p_smtp_host IN VARCHAR2,
                                       p_smtp_port IN NUMBER DEFAULT 25)
AS
l_mail_conn   UTL_SMTP.connection;
BEGIN
l_mail_conn := UTL_SMTP.open_connection(p_smtp_host, p_smtp_port);
UTL_SMTP.helo(l_mail_conn, p_smtp_host);
UTL_SMTP.mail(l_mail_conn, p_from);
UTL_SMTP.rcpt(l_mail_conn, p_to);
UTL_SMTP.data(l_mail_conn, p_message || UTL_TCP.crlf || UTL_TCP.crlf);
UTL_SMTP.quit(l_mail_conn);
END;
Begin
send_mail('[email protected]','[email protected]','test','10.0.0.100','25');
End;
The above code works i am able to send and receive mails.
We also create ACL as mentioned below
begin
dbms_network_acl_admin.create_acl (
acl => 'http_permission.xml', -- or any other name
description => 'HTTP Access',
principal => 'APEX_040100', -- the user name trying to access the network resource
is_grant => TRUE,
privilege => 'connect',
start_date => null,
end_date => null
end;
commit;
SELECT * FROM dba_network_acl_privileges where principal='APEX_040100';
begin
DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE(acl => 'http_permission.xml',
principal => 'APEX_040100',
is_grant => true,
privilege => 'connect');
end;
commit;
begin
DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE(acl => 'http_permission.xml',
principal => 'APEX_040100',
is_grant => true,
privilege => 'resolve');
end;
commit;
BEGIN
dbms_network_acl_admin.assign_acl (
acl => 'http_permission.xml',
host => '10.1.1.100', /*can be computer name or IP , wildcards are accepted as well for example - '*.us.oracle.com'*/
lower_port => 80,
upper_port => 80
END;
But still we are getting same ACL Error Please suggest US
ORA-24247: network access denied by access control list (ACL)
Thanks

Oracle APEX PL/SQL reports

Hello
I was wondering if someone can help me with the syntax error, or if someone can give an example how to implement dynamic query based on a select list item.
Last night I was looking how to implement simple PL/SQL report using Oracle Apex source region, but every time I try to run the page I'm getting an error "Flow=128 page=10 ORA-20001: wwv_flow_flash_chart.func_ret_sql_qry_err"
IF I put the same query into SQL developer and replace :P10_STATUS into string 'open', query returns correct results.
It works fine for single table, but not for inner joint.
Any help would be appreciated.
======================================================
declare
v_return varchar2(3000);
begin
IF :P10_STATUS is not null THEN
v_return := 'select p.priority, p.status, i.departments
from help_details p, help_department i
where status = :P10_STATUS';
END IF;
return v_return;
END;
=========================================================

Hi ATD,
Thanks for the suggestions.
Now i have replaced the code as
Declare
v_return varchar2(3000);
begin
     :P1_ITEM1:=:P1_DEPTLOV;
IF :P1_DEPTLOV IS NOT NULL
THEN
v_return:='select dname,deptno from dept ';
return v_return;
ELSE
V_RETURN:='SELECT ename,deptno FROM EMP ';
return v_return;
END IF;
plsql reportEdit
report error:
ORA-20001: Error fetching column value: ORA-01403: no data found
DEPTNO     Ename
and in case i change
select dname from dept ; for select dname ,deptno from dept ;
then i m able to see only the col deptno , but in query i never used dept...
I am unable to get where is the mistake ..
Kindly to a favour by using the above link & checking the application .

Nandini Thakur.

Error # 3021 - Invalid Relation. --- MS Access to Oracle APEX

Hello everybody.
I have 3 years working with Oracle APEX and now I have the need to migrate an Access database to Oracle and APEX.
I have:
- MS Access 2003 database
- Oracle SQL Developer 3.0.04.34
- Oracle 10g Database
I will try to provide all the relevant information.
I used the Access Exporter for Access 2003 tool from Oracle SQL Developer to creat both .xml (for SQL Dev) file and .sql file (for APEX) but the process show me an error mesassge that said: "Error # 3021 - Invalid Relation. No current record".
I read in OTN forum that it was because the migration tool can not access the system tables and that I need to modify permisions to allow "Read Data". I did this process and I was able to create .xml file, however if I chose Application Express to create .sql file or the option to create both files the same error shows.
I have been reading in this forum but didn't find a way to solve it.
Does any body knows how to solve this issue?
Any help is appreciated.
Thanks in advance for your help.

Hello,
I can't reproduce your issue.
Have you double-checked that the tables MSysAccessObjects, MSysACEs, MSysObjects, MSysQueries and MSysRelationships are visible and that the Admin user has at least Read Design and Read Data permission on those tables?
If that is the case, and the problem still happens, and you are able to give a copy of your .mdb file to Oracle, then I suggest to open a Service Request with Oracle Support so that the issue can be investigated.

Wolfgang

Commercial Application developed with Oracle APEX

Integrating Oracle Apex 4.0.2 with EBS R12.1.1

We could successfully integrate Oracle Apex 4.0.2 with EBS R12.1.1 with the help of http://www.oracle.com/technetwork/developer-tools/apex/apex-ebs-wp-cabot-consulting-169064.pdf.
The document says to navigate from EBS to Oracle Apex without any second login screen (works great!!), but now how do we navigate back to EBS from Oracle Apex (in same session) without any login screen again as like below
EBS User login --> EBS --> Oracle Apex --> EBS
Please help to achieve this.

Hi,
Under the Authentication scheme of your application in the Logout URL Section, give the following
wwv_flow_custom_auth_std.logout_then_go_to_url?p_args=&APP_ID.:http://xyz.ck.com:8010/OA_HTML/OA.jsp?OAFunc=OAHOMEPAGEspecify your ebiz suite url instead of http://xyz.ck.com:8010 in the above link.
so, that while pressing the Logout link in your apex, you wont be redirected to the ebiz login page again, and it will redirect to you ebiz menu home page back in the same session itself.
This will work for sure.
Good Luck!!!
Change your User handle from "805196" to a meaningful word.
