ORA-06502 on 'SQL query' report with sort in 'Report Attributes'

Hi All,
We get the next error if we set sorting on a column in a 'Report' based on a 'SQL query'. Removing the sort, error disappeares:
failed to parse SQL query:
ORA-06502: PL/SQL: numeric or value error: NULL index table key value
Any suggestions?
Erik

Erik,
Thanks, this explains it. By specifying the request as part of your URL you run into the recently uncovered issue. The request you're setting is REMFROMLIST and ADD2LIST. You probably either have links that include those requests or you have branches where you specify them. Either way, in order to get reports sorting to work, you'll have to make sure that the request strings are not part of your URL. This is a work-around and the upcoming HTML DB patch release will solve this issue.
One way of avoiding this is to have computations on the previous pages that set a napplication level or page level item to the REMFROMLIST and ADD2LIST values and then you can use those items for your conditions that are currently evaluating those strings.
Hope this helps and sorry for the inconvenience,
Marc

SQL query problem with sorting

Hi,
I have question regarding sql query . Right now I am getting the results like this if i use this sql query
select ID,Name,Desc,Priority from emp order by Priority ;
Priority is varchar field. I don't want to change the Priority field and cannot add a new column in the table. Because i don't have permission to do that.
ID Name Desc Priority
=============================================
234 paul paul desc Highest
3452 mike mike desc High
4342 smith smith desc Low
6565 kelly kelly desc Low
9878 nate nate desc Medium
3223 deb deb desc High
============================================
I need a query to get the results like that.
ID Name Desc Priority
=============================================
234 paul paul desc Highest
3452 mike mike desc High
3223 deb deb desc High
9878 nate nate desc Medium
4342 smith smith desc Low
6565 kelly kelly desc Low
============================================
If any one knows about this one, please let me know.
Thanks,
Bala

You are aware that there are differences in the SQL implementation between Sqlserver and Oracle? You could try something like this, if there's a INSTR function:
ORDER BY INSTR('Highest,High,Medium,Low,', Priority || ',')You may have to change the "Priority || ," to a "Priority + ','), if string concatenation is done differently in sqlserver. Don't know about the ('), maybe you need (").

Sql Query (updateable Report) returning ORA-06502: PL/SQL: numeric or value

Hi I have a Sql Query Report Region as defined below. On the report attributes I am not using any "Row Selector". In a After submit process I try to print out the results of the value I have entered in as a value in updatable report and i get the error: I am doing this as a test before i use the data to insert into another table...
I receive this error if I enter in a characters (not numeric) into the "Field Value" field.:
ORA-06502: PL/SQL: numeric or value error: character to number conversion error.
If I enter in a numeric into the "Field Value" text box, then I get the value displayed back without error. I need to be able to enter a varchar value without error.
My SQL QUERY is:
select i.INDEXED_FIELD_ID, i.field_name,
HTMLDB_ITEM.TEXT(3,d.indexed_field_value) field_value,
decode(f.required, 0, 'O', 1, 'R', 'NOT USED') REQUIRED
from XXVG_EFILE_DOCUMENT_FIELDS D,
xxvg_efile_type_fields f, xxvg_efile_indexed_fields i
WHERE f.indexed_field_id = i.indexed_field_id
and f.required in (0,1)
and i.indexed_field_id = d.indexed_field_id(+)
and d.document_id(+) = -1
and f.document_type_id = :p21_doc_type
My after submit process is the following...**Note** I am using P21_test as a field just to display my test. I receive the value back just fine without error if numeric. If varchar, that is when the problems occur. I have used just a length variable like the lettter 't' for testing and still receive the error.
DECLARE
vRow BINARY_INTEGER;
BEGIN
-- update field values
FOR i IN 1 .. HTMLDB_APPLICATION.g_f03.COUNT -- your field value
LOOP
vRow := HTMLDB_APPLICATION.g_f03(i);
IF vRow is Not NULL --means the field has data in it.
THEN
:p21_test := HTMLDB_APPLICATION.G_F03(i); --set a variable to the field with data.
END IF;
END LOOP;
END;
Is there a conversion I need to do? I do not want to do this via checkboxes as I dont want the user have to check a checkbox and then enter a value in. I just want a blank text box the user can enter a value in and then i can do an insert.
Thanks So much.

Thanks Scott, That did do the trick as the varchar is now displayed of the entered item.
How do i also display the value of indexed_field_id as well.
I have an insert where i need the indexed field id and the entered field value.
Thanks in advance.

Hi,
I was able to resolve the issue. I changed it to = To_Number while assigning.
and for other issue, earlier I choose "Select List" for drop down. I changed this to "Select list with Submit". for the issue of "depending on this values in the report should get change"
Thanks for your support,

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.

Report error:ORA-06502: PL/SQL: numeric or value error: character string bu

We face the above error in HTMLDB (APEX) application Ver 3.1.0. This occurs when we try to display more number of rows/records in drop-down list (LOV in tabular forms). We are able to display 200 records in LOV. When the list of records exceeds 230, we face the below error
report error:ORA-06502: PL/SQL: numeric or value error: character string buffer too small
the values listed in LOV are from tables (one of the columns in table)
Could anyone give us a solution?

Hi
As you are using a tabular form, you could actually do the following:
1 - In the tabular form column's attributes, set the following:
Display as: Select List (query based on LOV)
Display extra values: Yes
List of values definition: SELECT null d, null r FROM DUAL
2 - Add a new page item and set it to generate your select list
3 - Create an HTML region with no template and use the following for its source:
<script type="text/javascript">
function loadList(c, l)
var s = document.getElementsByName(c);
var lItem = document.getElementById(l);
var lLength = lItem.options.length;
var k;
var j;
var x = lItem.innerHTML;
var v;
var o;
var z;
for (k = 0; k < s.length; k++)
z = s[k];
v = z.value;
z.options.length = 0;
for (j = 0; j < lLength; j++)
o = new Option()
o.value = lItem[j].value;
o.text = lItem[j].text;
z.options[j] = o;
z.value = v;
if (z.selectedIndex == -1)
z.selectedIndex = 0;
loadList("f05", "P1_MGR");
</script>
(Change "f05" and "P1_MGR" as appropriate to your column and your new page item respectively)
Now, when you load the page, the select list contains a null entry plus the entry already on the database. The javascript kicks in automatically, loops through every entry in the "f05" column, copies the existing value, replaces the select list with the new page item version and sets its value to the copied value.
Your new page item could be in a DIV tag that has a style of "display:none" to hide it from view.

PL/SQL function body returning SQL query - ORA-06502: PL/SQL: numeric or value error

I'm attempting to dynamically generate a rather large SQL query via the "PL/SQL function body returning SQL query" report region option. The SQL query generated will possibly be over 32K. When I execute my page, I sometimes receive the "ORA-06502: PL/SQL: numeric or value error" which points to a larger than 32K query that was generated. I've seen other posts in the forum related to this dynamic SQL size limitation issue, but they are older (pre-2010) and point to the 32K limit of the DNS (EXECUTE IMMEDIATE) and DBMS_SQL. I found this post (dynamic sql enhancements in 11g) which discusses 11g no longer having the 32K size limitation for generating dynamic SQL. Our environment is on 11gR2 and using ApEx 4.2.1. I do not know which dynamic SQL method -- DNS or DBMS_SQL -- ApEx 4.2.1 is using. Can someone clarify for me which dynamic SQL method ApEx uses to implement the "PL/SQL function body returning SQL query" option?
As a test, I created a page on apex.oracle.com with a report region with the following source:
declare
l_stub varchar2(25) := 'select * from sys.dual ';
l_sql clob := l_stub || 'union all ';
br     number(3) := 33;
begin
while length ( l_sql ) < 34000 loop
    l_sql := l_sql || l_stub || 'union all ';
end loop;
l_sql := l_sql || l_stub;
for i in 1 .. ceil ( length ( l_sql ) / br ) loop
    dbms_output.put_line ( dbms_lob.substr ( l_sql, br, ( ( i - 1 ) * br ) + 1 ) );
end loop;
return l_sql;
end;
The dbms_output section is there to be able to run this code in SQL*Plus and confirm the size of the SQL is indeed larger than 32K. When running this in SQL*Plus, the procedure is successful and produces a proper SQL statement which can be executed. When I put this into the report region on apex.oracle.com, I get the ORA-06502 error.
I can certainly implement a work-around for my issue by creating a 'Before Header' process on the page which populates an ApEx collection with the data I am returning and then the report can simply select from the collection, but according to documentation, the above 32K limitation should be resolved in 11g. Thoughts?
Shane.

What setting do you use in your report properties - especially in Type and in Region Source?
If you have Type="SQL Query", then you should have a SELECT statement in the Region Source. Something like: SELECT .... FROM ... WHERE
According to the ERR-1101 error message, you have probably set Type to "SQL Query (PL/SQL function body returning SQL query)". In this situation APEX expects you to write a body of a PL/SQL function, that will generate the text of a SQL query that APEX should run. So it can be something like:
declare
mycond varchar2(4000);
begin
if :P1_REPORT_SEARCH is not null THEN
mycond:='WHERE LAST_NAME like :P1_REPORT_SEARCH ||''%''';
end if;
return 'select EMPLOYEE_ID, FIRST_NAME, LAST_NAME from EMPLOYEES ' ||mycond;
end;
And for escaping - are you interested in escaping the LIKE wildcards, or the quotes?
For escaping the wildcards in LIKE function so that when the user enters % you will find a record with % and not all functions, look into the SQL Reference:
http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14200/conditions007.htm
(You would than need to change the code of your function accordingly).
If you are interested in escaping the quotes, try to avoid concatenating the values entered by the user into the SQL. If you can, use bind variables instead - as I have in my example above. If you start concatenating the values into the text of SQL, you are open to SQLInjection - user can enter anything, even things that will break your SQL. If you really need to allow users to choose the operator, I would probably give them a separate combo for operators and a textfield for values, than you could check if the operator is one of the allowed ones and create the condition accordingly - and than still use bind variable for inserting the filtering value into the query.

ORA-06502: PL/SQL: at the end of an Excel Download report

Hi,
Within my apex application I have the possibility to download a file from ie. page 7 (which is linked to a query in page 8). When I open the downloaded file, I find an error at the end of the sheet:
<pre>report error:
ORA-06502: PL/SQL: numeric or value error: character to number conversion error</pre>
The thing is, the query that retrieves this report works perfectly, and when put in sql developer, it retrieves the same number of rows.
So it must be that after the query has finished with all the rows, in encounters some kind of character ie. a space , that can´t convert to number and thus gives the error.
Something worth noting is that, when I actually execute the page directly (page 8), that executes de query, it doesn´t give me the error on the excel.
Any recommendations on a possible reason are welcome.
Thank you,
Javier

I am also hitting this problem. Any pointer plz..

Display Image in Report Colum, ORA-06502: PL/SQL whe column format is set

Hi @all
i created a small table
CREATE TABLE my_sal201 (
grafikdid VARCHAR2(38) NULL,
grafik BLOB NULL,
mimetype VARCHAR2(255) NULL
then i inserted one column with a page process
BEGIN
IF (:p6_filename IS NOT NULL)
THEN
INSERT INTO my_sal201
(grafikdid, grafik, mimetype)
SELECT meb_ora.mkdid(), blob_content, 'image/gif'
FROM wwv_flow_files
WHERE NAME = :p6_filename;
DELETE wwv_flow_files
WHERE NAME = :p6_filename;
:p6_filename := NULL;
END IF;
END;
after that i want to show the columns and the image in a report. so i created a report in a new region quite similar to the example in the obe
it works fine, the image columns is shown as "[datatype]"
whenever i change the format of the image colum of the report to
DOWNLOAD:MY_SAL201:GRAFIK:GRAFIKDID::::::inline:Herunterladen
(just one example, IMAGE:... does not work as well)
no more rows are shown but the error h3. "ORA-06502: PL/SQL: numerischer oder Wertefehler: Fehler beim Konvertieren von Zeichen zu Zahl"
what did i do wrong?

i'm to silly to work with images :-ß
i did copy ur example to another app on http://apex.oracle.com/pls/otn/. fine->igames are shown.
on a new page in my local app, i did exactly the same (create a table, procedure, ect) it does not work.
rows are shown inthe report, but no images, instead the icon for a broken/missing image is displayed.
i tried to debug using firebug:
in the sample app on otn, when i point the mnouse over the procedure call, the image appears in a tool-tip
in my app, the code is quite simmilar, nothing happens. no icon

SEM_MATCH query failed: ORA-06502: PL/SQL: numeric or value error: characte

I use sqlplus to run a query statement with the SEM_MATCH function, and got the following error:
ERROR at line 1:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at "MDSYS.RDF_MATCH_IMPL_T", line 176
ORA-06512: at line 1
Could it be a bug in the MDSYS.RDF_MATCH_IMPLE_T? I find the MDSYS.RDF_MATCH_IMPL_T in Oracle SQL Developer, but the code is not readable.
Thanks.

It is not likely to be a bug, but an issue of how SEM_MATCH is used. It would be best to contact Oracle Support with your sample SEM_MATCH query that causes the error.

I am running a loop to just spool output data using 'dbms_output.put_line' and I keep getting this error after a few records. I resorted it and it happen at a different interval. Could it have to do with the length of the item I am trying to spool? Thanks.

Scrolling through hundreds/thousands of options in a select list is a pain for users, and huge select lists produce bloated pages that impact load times and network bandwidth. That list of around 200 countries you find on many sites is about the sensible maximum length for a select list.

I think its better you use APEX 4.x version ratherthan using old version.
You will get more features and some bug fixes and also it's easy for you to get some help when you need.

Report error: ORA-06502: PL/SQL: numeric or value error: NULL index table k

Hi everybody,
I have two Distinct Databases on two distinct servers. (Oracle Ent. Release 10.2.0.3.0 on AIX 5.3). After I install the latest patch last week, One of the APEX installation has some problems on Home>Application Builder Page. The error message is very random and
report error:
ORA-06502: PL/SQL: numeric or value error: NULL index table key value.
When i change the view (details to icons), everything goes to normal. This error message is reflected some of the pages (report region) of some of my applications randomly. When it appears in a report region, i deselect the order method of the region, the result is normal.
But the other APEX application on the other instance has no problem. It is a bug? or Should i re-install the APEX instance?
Thank you for your interest?
