Owa_util.listprint error

Hi,
I need a drop down list and am using this:
owa_util.listprint('SELECT mc_id FROM or_menlo_clients','p_clientid',1,FALSE);
but I'm getting this error:
ERROR at line 1:
ORA-01007: variable not in select list
ORA-06512: at "SYS.DBMS_SYS_SQL", line 1147
ORA-06512: at "SYS.DBMS_SQL", line 339
ORA-06512: at "SYS.OWA_UTIL", line 1892
ORA-06512: at "SYS.OWA_UTIL", line 1908
I can't figure it out, the command is very simple.
Thanks!

Hi,
I wrote a test procedure in the portal schema and granted it to public:
create or replace procedure test
as
begin
htp.formOpen('testForm');
owa_util.listprint('select ename,empno,hiredate from scott.emp','col_combo',20);
htp.formClose;
end test;
Ran this from the browser :http://<hostname>:port/pls/dadname/portal30.test
It works fine.

Procedure trouble(owa_util.listPrint)

I'm trying to create some very basic "web" procedures and I'm now stuck on a problem.
create or replace procedure web_test2
as
begin
HTP.HTMLOPEN;
HTP.HEADOPEN;
HTP.TITLE('Webb Test');
HTP.HEADCLOSE;
HTP.BODYOPEN;
HTP.FORMOPEN( CURL => 'testschema.web_test2');

HTP.FORMCLOSE;
HTP.BODYCLOSE;
HTP.HTMLCLOSE;
END;
If I take away the line owa_util.listprint the procedure works fine. any idea on what the problem is?

What is the error / message that you get ?In my web browser I get "The page cannot be found", but if I take away the owa_util from the procedure it works fine in the browser.
if i try to execute the procedure from sql*plus I get this error:
BEGIN web_test2; END;
ERROR at line 1:

Why do you want to use the owa_util package ?can I dynamically create a list based on a table using HTP package?
if it works any tip on how to do it.

Example of owa_util.listprint

can yoy help me and send me a owa_util.listprint's example.

OWA_UTIL

Dear Oracle Guru's
I was going thru the documentation on OWA_UTIL and tried the examples given.
For an example , it suggested something like this
http://myhost:7777/pls/hr/showemps
in which showemps is the name of the function created using OWA_UTIL
when i used this url it gave the Page cannot be displayed error. I am unable to understand what pls , hr and myhost stands ....is it application server or database server ?
please help me
with warm regards

Ora-06502:pl/sql and ora-06512 at sys.owa_util errors

Greetings -
I have just installed APEX 2.2 in my 9.2.0.7 database and am going through the exercises in the "2 Day+ Application Express Developer's Guide." I was making good progress, until I got to Chapter 5, How to Control Form Layout. I created the script "ht_emp", as instructed. Everything in the script works, except for the "create or replace trigger bi_ht_emp" part. It fails with the following errors:
ORA-06502: PL/SQL: numeric or value error ORA-06512: at "SYS.OWA_UTIL", lone 328 ORA-06512: at "SYS.HTP", line 862 ORA-06512: at "SYS.HTP", line 977 ORA-06512: at "SYS.HTP", line 995 ORA-06512: at "FLOWS_020200.WWV_FLOW_SW_API", line 428 ORA-01003: no statement parsed. I have confirmed that nls_length_semantics = BYTE
Any suggestions?

Error while setting Owa_Util.Mime_Header

Hi.....
I have to make code to download BLOB file from my custom table Oracle APEX.
I am setting MIME Header using the following statement.
owa_util.mime_header(nvl( v_mime,'application/octet'), FALSE );
htp.p('Content-type: ' || v_mime);
htp.p('Content-length: ' || v_length);
htp.p('Content-Disposition: attachment; filename="'||replace(replace(substr(v_file_name,instr(v_file_name,'/')+1),chr(10),null),chr(13),null)|| '"');
owa_util.http_header_close;
I am using this code to download BLOB file from table.
But i am getting following error:
Error report:

Can anyone tell me how to come out of this error.
I am not able to understand this error.

My understanding is that this will open the window to Open/Save/Cancel the output in Excel.....
But for some reason, it simply displays in a browser window.....
The first line in the windows is:
Content-type: application/vnd.ms-excel Content-Disposition: filename="test.xls"
followed by the HTML Table....
Why will it not open in Excel for me?Something is not getting recognized properly.
Try hard-coding the functionality you want into a static HTML document. Then work on using owa_util.mime_header or Like MichaelS suggested htp.p surrounded by any needed tags w/options to duplicate the working static document's functionality.

Owa_util.get_cgi_env( 'REMOTE_ADDR' ) fails with PLSQL numeric error

APEX Listener 2.0.1
APEX 4.2.2
Oracle 11gR2
Linux RHEL 6.3
Glassfish 3.1.2
=============
After upgrading from APEX Listener 1.1.4 -> 2.0.1 the procedure owa_util.get_cgi_env( 'REMOTE_ADDR' ) fails to return the remote IP Address and instead I get the error
ORA-06502: PL/SQL: numeric or value error
Has something changed with the new APEX Listener 2.0.1? Is there a configuration element in the config or web.xml file that has to be changed before deploying the APEX Listener to GlassFish?
Thanks.

Hi I cannot reproduce this issue, here's the test case I used, can you try this and report the output generated:
create or replace procedure test_cgi as
begin
owa_util.print_cgi_env;
htp.prn(owa_util.get_cgi_env( 'REMOTE_ADDR' ));
end;
grant execute on test_cgi to apex_public_user
Then I invoke the above procedure as follows:
http://localhost:8080/apex/<workspace-schema-name>.test_cgi
where <workspace-schema-name> is the database schema that the APEX workspace is using.
Which produces output like the following:

Unable to run procedure due to error in package OWA_UTIL

Hi,
I have written a nice PL/SQL procedure called 'send_notification'.. My procedure begins like this :
create or replace
procedure             send_notification
is
ws_id               number;
l_body              clob;

l_cgi_var_name      varchar2(100) default 'SERVER_NAME';
l_server_name       varchar2(2000) ;
begin
l_server_name := owa_util.get_cgi_env(l_cgi_var_name) ;
The procedure is nicely compiled without errors. When I run the procedure "send_notification", I get these error messages :
ORA-06502: PL/SQL : erreur numérique ou erreur sur une valeur
ORA-06512: à "SYS.OWA_UTIL", ligne 356
ORA-06512: à "SIVOA.SEND_NOTIFICATION", ligne 10

The lines 354-356 of the package OWA.UTIL shows this :
function get_cgi_env(param_name in varchar2) return varchar2 is
upper_param_name varchar2(2000) := upper(param_name);
begin
I have successfully compiled the package OWA_UTIL.
Thank you for your kind help.

ORA-06502: PL/SQL: numeric or value error ORA-06512: at "SYS.OWA_UTIL"

Was working on tutorial from the:
Oracle Database Express Edition 2 Day Plus Application Express Developer Guide
Working on the section 4: How to Control Form Layout.
Ran into a problem trying to compile the Create HT-EMP Table script.
keep getting this error for this particular segment creating the bu_ht_emp trigger:
pp. 4-2 and 4-3
CREATE OR REPLACE TRIGGER bi_ht_emp
BEFORE INSERT ON ht_emp
FOR EACH ROW
BEGIN

:new.rec_create_date := SYSDATE;
END;
ORA-06502: PL/SQL: numeric or value error ORA-06512: at "SYS.OWA_UTIL", line 354....etc
I've check the syntax for the entire script and it all checks out. Does anyone have a clue why this is failing?

If I'm looking at the same DDL, not seeing where it would throw an owa_util error, are you running it in the apex script editor?
Just plain sqlplus doesn't like the empty line stuck in with the list of check constraints on the emp_dept column, after fixing that up (and dropping the sequence that got created on the first pass) the DDL and insert runs fine-

SYS.OWA_UTIL error

Hi all,
I am trying to run a report from Oracle application server and I am receiving the following error. The reports can be accessed from the web and a .Net web application. The reports run without any error when invoked from the web but raise the following error when invoked from the .Net app. I read in one of the posts that we cannot call OWA_UTIL package from a non web environment. Can you please advise how to avoid this issue.

I really appreciate your time and effort. Thanks.

Hello Michael,
Thanks for the quick reply. I am just curious to know that difference between the following.
In one of your earlier posting you mentioned that we can initialize using
Declare
name_arr OWA.VC_ARR;
value_arr OWA.VC_ARR;
BEGIN
begin
if owa.num_cgi_vars is null
then
OWA.INIT_CGI_ENV(0, NAME_ARR, VALUE_ARR);
end if;
end;
In the current post you are referring to
declare
param_val owa.vc_arr;
begin
param_val (1) := 1;
owa.init_cgi_env (param_val);
htp.p ('Some Text');
htp.showpage ();
end;
Does it matter which procedure I call?

Actually, the error comes up when I try to execute any of these lines:
OWA_UTIL.mime_header (NVL (v_mime, 'application/octet'), FALSE);
-- set the size so the browser knows how much to download
HTP.p ('Content-length: ' || v_length);
-- the filename will be used by the browser if the users does a save as
HTP.p ( 'Content-Disposition: attachment; filename="'
|| REPLACE (REPLACE (SUBSTR (v_file_name,
INSTR (v_file_name, '/') + 1
CHR (10),
NULL
CHR (13),
NULL
|| '"'
Is there any security issue?

OWA_UTIL and HTP across database link

Has anyone figured out how to use the features of OWA_UTIL, such as listprint, across a database link? I can create a drop list on data that is in the portal instance. But if I try to create a list based on a table in a back-end database through a database link, it generates errors.
Also, I create a procedure to generate a dynamic page portlet using htp calls and it works fine if the procedure is located in the portal instance. But move the code to the back-end database and access via a synonym and database link and it generates errors out of the owa_util package.

Create a view on your local db using tables over the db link and base your list on that view.

Error While loading a image from database

Purpose
Error While loading the Image from the database
ORA-06502: PL/SQL : numeric or value error:Character string buffer too small

Requirement:
I am developing the web pages using PSP(Pl/sql Serverpages) . I have a requirement to show a image in the webpage. I got the following procedures from the oracle website.
I have created the following table to store the images
create table DEMO
ID INTEGER not null,
THEBLOB BLOB
And I also uploaded the Images. Now I am try to get a image from the table using the following procedure .But I am getting the error message line 25( htp.prn( utl_raw.cast_to_varchar2( l_raw ) );) .at it throws the following error messages

What I have to do to correct this problem. This demo procedure and table that I am downloaded from oracle. Some where I made a mistake. any help??
Thanks,
Nats

Hi Satish,
I have set the raw value as 3600 but still its gives the same error only. When I debug the procedure its throwing the error stack in
SYS.htp.prn procedure of the following line of code
if (rows_in < pack_after) then
while ((len - loc) >= HTBUF_LEN)
loop
rows_in := rows_in + 1;
htbuf(rows_in) := substr(cbuf, loc + 1, HTBUF_LEN);
loc := loc + HTBUF_LEN;
end loop;
if (loc < len)
then
rows_in := rows_in + 1;
htbuf(rows_in) := substr(cbuf, loc + 1);
end if;
return;
end if;
Its a system procedure. I don't no how to proceed .. I am really stucked on this....is their any other method to take picture from the database and displayed in the web page.....???? any idea..../suggesstion??
Thanks for your help!!!.

It shows a POP up window by which u can save or opens the file. But no pop up displayed in this case.

Hi,
Made the same changes but still getting the same error.
The earlier URL also that I had mentoned would dynamically make this url mentioned by you and then shows the pop up window.
However when I am right clicking on the download link and then clicking 'Save target as' then this error message is provided:
Internet Cannot download [schema name].download_myfile2 from [DNS name]
Internet Explorer was not able to open this Internet Site.The requested site is either unavailable or cannot be found .Please try again.
Please help..

A question about error with jasperserver for pdf and Apex

I have created a pdf report on jasperserver and I can call it from apex via a url and it displays fine. The url is this format {http://server:port/jasperserver/flow.html?_flowId=viewReportFlow&reportUnit=/reports/Apex/deptemp&output=pdf&deptNo=#DEPTNO#&j_username=un&j_password=pw}
However, I am trying to follow a stored procedure executed from Apex so it would not expose the username/pwd in the url like above.
If I am reading the apache error log correctly it is erroring in this piece of the code below where it executes {Dbms_Lob.writeAppend}

exception when utl_http.end_of_body then

end;
end loop;
Utl_Http.end_response(vResponse);}
The error log says this; HTTP-500 ORA-14453: attempt to use a LOB of a temporary table, whose data has alreadybeen purged\n
What is this error telling me and how can I correct it?
The stored procedure I am following is below but replaced the vReportURL with my url like above that works.
Thank you,
Mark

I am new to working with working with jasperserver to apex interfacing, and also using utl_http with binary data.
But I guess typing my question down helped me figure out a way to make it work for me.
I combined info from http://www.oracle-base.com/articles/misc/RetrievingHTMLandBinariesIntoTablesOverHTTP.php
and from http://sqlcur.blogspot.com/2009_02_01_archive.html
to come up with this procedure.
{create or replace PROCEDURE download_file (p_url IN VARCHAR2) AS
l_http_request   UTL_HTTP.req;
l_http_response UTL_HTTP.resp;
l_blob           BLOB;
l_raw            RAW(32767);
BEGIN
-- Initialize the BLOB.
DBMS_LOB.createtemporary(l_blob, FALSE);
-- Make a HTTP request, like a browser had called it, and get the response
l_http_request := UTL_HTTP.begin_request(p_url);
Utl_Http.set_header(l_http_request, 'User-Agent', 'Mozilla/4.0');
l_http_response := UTL_HTTP.get_response(l_http_request);
-- Copy the response into the BLOB.
BEGIN
    LOOP
      UTL_HTTP.read_raw(l_http_response, l_raw, 32767);
      DBMS_LOB.writeappend (l_blob, UTL_RAW.length(l_raw), l_raw);
    END LOOP;
EXCEPTION
    WHEN UTL_HTTP.end_of_body THEN
      UTL_HTTP.end_response(l_http_response);
END;
-- make it display in apex
owa_util.mime_header('application/pdf',false);
htp.p('Content-length: ' || dbms_lob.getlength(l_blob));
owa_util.http_header_close;
wpg_docload.download_file(l_blob);
-- Release the resources associated with the temporary LOB.
DBMS_LOB.freetemporary(l_blob);
EXCEPTION
WHEN OTHERS THEN
    UTL_HTTP.end_response(l_http_response);
    DBMS_LOB.freetemporary(l_blob);
    RAISE;
END download_file; }
Don;t know what I did wrong, but I could not create an 'on-demand' process to call my procedure. I did not understand what it means when it says 'To create an on-demand page process, at least one application level process must be created with the type 'ON-DEMAND'.
so I had to use a blank page with a call to my procedure in the onload - before header process and that seems to work ok.
Thank you,
Mark
