BI Publisher Report Query Error: "character string buffer too small"

Using apex.oracle.com, I am trying to make a Report Query (Shared Components > Report Queries) based on many columns (around 60).
When I enter my SQL in the "Source Query" Text Area and then click Test Report I get the following error:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small In order to try to make the simplest test case possible for this, I then tried entering SQL selecting just from DUAL.
The following SQL fails with the error mentioned above.
SELECT
'wibble' as a
,'wibble' as b
,'wibble' as c
,'wibble' as d
,'wibble' as e
,'wibble' as f

FROM dualRemoving the last column from this SQL query (bringing the total number of columns down to 45) as follows and then clicking "Test Report" works successfully.
SELECT
'wibble' as a

,'wibble' as ao
,'wibble' as ap
,'wibble' as aq
,'wibble' as ar
,'wibble' as at
,'wibble' as au
FROM dualSo the question is: Is there a hard-coded limit of 45 columns for a Source Query? Or is there something else causing this error message?
(For information in the above example I have "Use Generic Report Layout" selected and the output format set to "PDF")
Thanks very much in advance for any comments or suggestions,
Andy

Thanks for the suggestion Simon.
I just created a view based on the 46-column SELECT statement from dual above and then set "SELECT * FROM myview" as the Source Query.
Unfortunately I get exactly the same error.
Thanks,
Andy

Report error: numeric or value error: character string buffer too small.

Full Details:
report error:
ORA-20001: Error fetching column value: ORA-06502: PL/SQL: numeric or value error: character string buffer too small.
MS Access runs this query but when I try to call a 'List of Values' in APEX that is in excess of 800 the error above displays. If I use a 'Pop Up' it will work but splits the list at 500. This is annoying and slower as I would like to be able to display all 850+ items in a named list of values. How do I increase the buffer size?
Kind Regards,
Steve

Steve,
Could you please post the query you're using? You're most like hitting one of two possible varchar2 limitations. If you're calling the apex_item API in your SQL query to render the select list, then you're limited to 8000 characters, this your option values and HTML code used to render this. In this case using the "XL" versions of the APIs might help, e.g. select_list_from_query_xl, because those return CLOBs. If you're already using those or if you're using the built-in display type "select list", then you could potentially hit the 32k character limit of varchar2 values in PL/SQL. In that case the best alternative is using a popup LOV instead.

Marc

Hi Helios,
Many thanks for your reply.
I am able to figure out the issue. In the code we have
l_analysis_report := l_analysis_report ||'<tr><td align="center">'|| curr_refresh.analysis_name
                      || '</td><td align="center">' || curr_refresh.start_time || '</td><td align="center">'
                      || curr_refresh.end_time || '</td><td align="center">'|| curr_refresh.RUN_TIME_SECS ||
                      '</td><td align="center">'|| curr_refresh.status ||
                      '</td> </tr>' || UTL_TCP.CRLF;
                  exit when length (l_analysis_report) > 32500;where "l_analysis_report VARCHAR2(32767);"
The issue is report has more characters, and when executing it throws the error " ORA-06502: PL/SQL: numeric or value error: character string buffer too small ".
Can you please let me know how to have more characters/data in the report. Will CLOB help if yes, please let me know how to use it.
Kindly suggest some options.

Sunny

LOV - PL/SQL: numeric or value error: character string buffer too small

I have a field set to 'text field with autocomplete' and now that the data that is used for the LOV has increased dramatically it returns the following error 'ORA-06502: PL/SQL: numeric or value error: character string buffer too small'. Through trial and error I determined that if I restricted the number of rows returned using rownum < nnn then it would work. I then determined that I could use the trim and substring functions and remove the rownum restriction and it would work. Below is the LOV query. I have seen a couple of other posts similar to my problem and one of them asked if there was a way to increase the buffer size, but it was never answered. Is there a way, such as a parameter setting, that I could increase the buffer size for LOVs?
select distinct substr(trim(item_requested),1,50) d
from consolidated_components
order by 1
Thank you.

Hi Scott
Thanks very much for jumping in here.
No, I didn't use the wizard to create the page. It was a manual operation but to tell you the truth the page has been changed so many times as I was working on different functionality and appearance that anything could have happened. I ended up having to manually create row processing processes and delete other processes, creating and hiding buttons, changing the way I'm passing item values, etc. I realize regardless of what I do as a developer the software should be able to handle all changes through it's interface but I've been in this business long enough to be realistic.
I also could have done something blatantly stupid as I continue to learn this product. For those of us not yet totally comfortable with all the web development technology, Javascript, AJAX, etc., but are asked to develop applications that work best using those technologies sometimes we make elementary blunders.
Thanks very much for your help. It is indeed appreciated.

The error message should have included a line number for you to reference back to your code to know what line the error was occurring on.
That said, look at the documentation for SUBSTR as you are using the third parm incorrectly. It is length, not end position. That's your issue.

OLAP -- ORA-6502: numeric or value error: character string buffer too small

Hi all,
We got installed Oracle 9201. After applying the patch #2761332 (to upgrade up to 9203)
and interim patch #2897078 (9203 Patch 1) we always get OLAP Catalog invalid.
I've tried to mend this problem by doing all it is said in Notes 23268.1 & 226443.1 but
my effort was worthless. OLAP catalog is still invalid though BI_Checkconfig says is okay at all.
Nevertheless, we can create dimensions, cubes and measures well, but other problem arises when
I try to add a dimension to a cube issuing the following command:
cwm2_olap_cube.add_dimension_to_cube( owner, NAME, owner, DIM_NAME);
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at "OLAPSYS.CWM2_OLAP_MANAGER", line 380
ORA-06512: at "OLAPSYS.CWM2_OLAP_MANAGER", line 397
ORA-06512: at "OLAPSYS.CWM2_OLAP_CUBE", line 281
Paying attention to other metalink/otn threads about this subject we found similar problems with
Oracle 9203 in Japanese (keeping in mind we use Oracle in Spanish).
Any patch we can apply? Any ideas? Your comments are welcome ...
Thanks in advanced !!

We have fixed the problem !!! :-DDD

ORA-0605: PL/SQL: numeric or value error: character string buffer too small

I get this error on two function activities in a workflow of mine. I don't even get into the pl/sql procedure call.
The exact error is:
Error Name -6502
Error Message: ORA-0605: PL/SQL: numeric or value error: character string buffer too small
Error Stack: @#@Wf_Engine_Util.Function_Call(MY_PACKAGE.MY_PROC, ITEM_TYPE, ITEM_KEY, 6519, RUN)
If I retry the step (expedite -> retry) it runs until it hits the second function which does the same thing (there is a function in between the two functions that do not have any issues). I then have to retry that step as well. Any ideas?
This seems similar to the following issue that does not have a resolution posted:
ORA-06502 PL/SQL numeric or value error in wf process
I've tried commenting out the bodies of the procedures called but that does not help (again -- im not getting into the bodies but im not sure what else it could be).
Any ideas or suggestions?

Hi,
Does this happen on every instance of the process, or just a few?
Are these activities in the middle, or right at the start of the flow?
Are any other activities being performed correctly first? If so, are these standard or bespoke?
My inclination would be that there is some kind of variable that is being populated (or concatenated onto), which is growing too big. When the process errors, it gets cleared, which is why an expedite would move the activity on.

Listener Error - character string buffer too small (ORA-06502)

I am running into a very strange problem with the APEX listener on seemingly random pages. I can hit every page in my application just fine, but as soon as I hit this specific one, Glassfish throws an HTTP 500 error. If I click Debug, the page seems to load fine with no indications of trouble, but as soon as I turn debug back off, it goes back to the HTTP 500 error. I don't see anything special about the page that makes this happen. It is pretty simple and has 4 regions. I have noticed that if I set any 1 of the 4 regions to "Never display", the page loads fine. It's like having all 4 of them enabled at once are causing some overload, even though it's actually a smaller amount of data than most of my other pages.
**Update: I just discovered this only happens if I'm logged into the workspace first and then try to run the page! If I log out of APEX and then hit the application as a normal user, page loads error-free. This is still an annoying problem, but at least it seems I have a decent workaround since regular users never see it.
After a couple days, I noticed the exact same problem on a second APEX application I'm using. Again, it is on some random page whereas all the other pages work fine.
Both applications and pages in question worked without issue in APEX 3.x. I am trying to get an APEX application up and running on the latest version.
I have tried both Glassfish server and simply downloading the latest listener (version 1.1.1) and running it in standalone mode. I get the problem both ways, which is why it seems it's a listener issue.
I have seen a few other threads of people having this problem, but I never did find anyone with a solution, and most of the posts stopped back in December.
Some details on my environment:
Database version: Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bi
APEX version: 4.0.2
Webserver: Glassfish 3.1
Here is the log entry from Glassfish when the HTTP 500 error displays as I try to load one of the bugged pages.

Brian,
this post is going to get a bit longer, so the summary comes first.
h6. Summary
1. I could reproduce the problem on my system using the APEX Listener in standalone mode.
2. I don't think the problem is content-related in the sense that you have any issue in your page or database contents.
3. I have a workaround for your problem.
h6. Error message
Having that error in my environment made me start to think. I not only disabled some item and got it work, but I could also add something to achieve this effect.
So I came to think, this really is somewhere deep down. The error message doesn't seem very helpful on first sight, but when starting to follow on what's happening there, things get clearer:
APEX generates pages dynamically, replacing substitution strings and other tokens to get the actual page definition. This has to be read by a requesting client. The use of VARCHAR2 as buffer introduces a limit of 32767 bytes, after which the contents is handled as CLOB instead.
h6. Analysis
Obviously, there are cases where the "estimation" fails. Of course, this is may only be relevant in rare cases, because:
1. If a page would exceed the maximum without some charset interpretation problem, the buffer would be switched to clob.
2. If a page stays small enough to stay below 32767 even with some characters that are acutally larger then expected, the buffer isn't busted.
To find out, if your could be one of these rare cases, I investigated the HTTP headers, focussing on X-DB-Content-length and made an odd observation.
Test case 1: "Go" button disabled, so the page runs fine with APEX Listener
1. It has *31968 bytes* when coming from APEX Listener with a Go button disabled.
2. It has *31938 bytes* according to the header set by EPG - for exactly the same page.
That makes a difference of 30 bytes for what is expected to be the same contents.
Test case 2: The button is enabled again
1. This causes the page load to crash in APEX Listener.
2. EPG transports *32341 bytes* according to that header.
So we are pretty close to the hard limit for the VARCHAR2 buffer.
For some reason, APEX Listener seems to cause a false calculation of the actual page size. Whether this is due to some charset problem or due to some other problem with response handling, I don't know. The 30 bytes difference may result from the odd header "X-ORACLE-IGNORE" with value "IGNORE, IGNORE, IGNORE, IGNORE" sent by the APEX Listener. This value has exactly 30 bytes in length, but this could be coincidence, as there are more differences in headers. If I add the size of all headers, we are even closer to the buffer limit and probably exceed it when some items need more bytes than expected.
This could even be as simple as a line break, as your page has about 424 lines when I disabled the button... Adding 1 byte per line to the 32341 bytes of the EPG, I get 32765 bytes. Now add that button (403 bytes difference on EPG) and you exceeed the limit. Reduce that value by the line count again and you are still below.
Could be coincidence as well, but makes me wonder.
h6. Workaround
To make sure that we were actually hitting that limit, I now introduce my suggestion for a workaround.
Test case 3: Add a hidden item
1. APEX Listener loads the page, stating the size to be *32876 bytes*
2. EPG sees 30 bytes less and transmits the header with *32846 bytes*
h6. Conclusion
I can't give you a real solution for that problem, nor do I have a definitive answer on what is the root cause for it. It seems, only one of the developers may find it. But I can offer you a workaround, which is to just add some hidden item to your page so it exceeds the limit for the VARCHAR2 buffer and gets handled as clob.
Note that this may occur outside the app builder as well. The app builder just renders some additional items when starting that page, so it has a different size from its productive representation. On the other hand, I may start counting the size of that additional page section - I wouldn't wonder if that results in a value around 400 bytes, and this is the forgotten part...
Unfortunately, if it actually is happening outside of the app builder, this workaround isn't very handy: Dynamic contents can't be calculated that easy all the time, so you may have cases where you just don't know in advance if you are close to the limit and have to add some item to exceed it or if you've already exceeded it or if you are far below, or close enough to actually hit it when adding just one byte...

if you want to find out which of your two variables are causing the problem, then use pragma exception_init along with "begin end exception" blocks within the loop.
I've removed the procedure specification, so you can test this in SQL Plus. You need to supply a number to the Header_id1 variable something like this:

ORA-06502 PLSQL Numeric or value error character string buffer too small

Hi
Gurus help!!
I received error message "ORA-06502: PL/SQL:Numeric or value error: character strong buffer too small." I use example code of "AJAX Get Multiple Values Tabular I" from Denes Kubicek http://apex.oracle.com/pls/otn/f?p=31517:239.
I did
1) create an application process on demand (set_multi_items_tabular)
2) create two application items (temporary_application_item and t_rownum)
3) create a report page (I assume) and put the below into the page header
<script language="JavaScript" type="text/javascript">
function f_set_multi_items_tabular(pValue, pRow){
var get = new htmldb_Get(null,html_GetElement('pFlowId').value,

get.add('TEMPORARY_APPLICATION_ITEM',pValue)
get.add('T_ROWNUM',pRow)
}else{
get.add('TEMPORARY_APPLICATION_ITEM','null')
gReturn = get.get('XML');
if(gReturn){
var l_Count = gReturn.getElementsByTagName("item").length;
for(var i = 0;i<l_Count;i++){
var l_Opt_Xml = gReturn.getElementsByTagName("item");
var l_ID = l_Opt_Xml.getAttribute('id');
var l_El = html_GetElement(l_ID);

Am I missing some steps? Please advise and thank you in advance.

Stupid me!! The size of select list is too big. After I delete some record from the table, that programs. Thanks for Denes Kubicek. I guess there is limitation of select list in Apex.

ORA-06502: numeric or value error: character string buffer too small

I have a stored proc with a parameter pio_med_rec_nbr patient.med_rec_nbr%TYPE
where patient.med_rec_nbr is a varchar2(12) .
character set is we8mswin1252 semantics are bytes
the stored proc retrieves max(med_rec_nbr) into nTmp( number) from a reference table
and does pio_med_rec_nbr := lpad(TO_CHAR(nTmp),12,'0')
which throws the ORA-06502: PL/SQL: numeric or value error: character string buffer too smallwhen I check the length, I get length(pio_med_rec_nbr) = 12
I can pass one digit or null but no more. Any idea what I need to do to debug this? I can do xxtmp := lpad(TO_CHAR(nTmp),12,'0') where xxtmp varchar2(255), so I know the assignments are okay.
Thanks,

Do, pio_med_rec_nbr := trim(lpad(TO_CHAR(nTmp),12,'0') )
