Character string buffer too small (select list query based LOV)

Hi,
Using the select list query based LOV with a select witch is too big, you get this error.
report error:
ORA-20001: Error fetching column value: ORA-06502: PL/SQL: numeric or value error: character string buffer too small
When using the Popup LOV query based LOV) then it works nice.
Can that be solved somehow?
With the Popup LOV the return value is displayed in stead of the description.

Hi Andy,
How do I incorporate your suggestion on a report ?
Example : I have
select apex_item.display_and_save(1,column1,5) col1,
apex_item.display_and_save(2,column2,5) col2 ,
apex_item.popup_from_query(3, emp_name, 'select user_name, name empname from table2) col3
Table 2 is a long list , and I'm getting string buffer too small due to this.
Your suggestion with HTP is good but I'm not sure how to implement it for reports as I'll like the user to change the values with the select_list.
I'm not using forms as they want mulit-record on the same page.
Hope to hear back from you soon.
Thanks very much.

Hi,
That error occurs when the variables that are being set are too short to hold the entire value being selected.
Either make the variables longer, or the columns shorter.
If you need mnore help, post
(1) The version of Oracle (and any other relevant software) you're using
(2) A little sample data (just enough to show what the problem is) from all the relevant tables
(3) The results you want from that data
(4) Your formatted code
(5) The full error message(s), including line number
Executable SQL statements (like "CREATE TABLE AS ..." or "INSERT ..." statements) are best for (2).
Formatted tabular output is okay for (3) and essential for (4). Type {code} before and after the tabular text, to preserve spacing.

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

When I enter my SQL in the "Source Query" Text Area and then click Test Report I get the following error:

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.

HTMLDB_ITEM.POPUP_FROM_QUERY - character string buffer too small

I am creating a updateable report with a popup_from_query item on a table with a high number of columns (40 columns) where every column should be displayed as a popup_from_query.
I get the following error message when running the page:
report error:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
*** It seems the longer the column list gets, the shorter the p_lov_query parameter could be.
- Region 1: If you use only one column, your lov query fails with a statement that is 807+ characters. (if you use 806 it will work without an error).
- Region 2: If you use only two column, you will fail just with a value of 800.
- Region ?: I have 40 columns, now my query fails of about 30 charachters.

Has anyone some suggestions or workaround for updateable reports with a lot of columns where popup's are needed?

Hallo,
Thank you a lot for that hint. But if this would be the case, why does Region 2 work then?
Any further comments are welcome.
Thx, Willi
P.S.: I had reached the 2000 items (<input>) limit, but now only display less 2000 items on the page: "Your browser sent a request that this server could not understand.

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

"Character String Buffer too small" Classic Report Apex 3.2.1

Hello Everyone,
I know it is very old version I am discussing here but that is what we have in our environment, would really appreciate if anyone can help out.
I have a classic report with the below query, in this I have added a filter using a select list item (P70_GROUP).
SELECT vws.ServerID AS Display_ID, vws.ServerID AS ID, vws.Hostname, vws.ServerStatus, vws.SiteName AS Site, vws.Client, vws.CoreHours, vws.Patch_Notes, vws.PATCH_DEP, vws.Patch_Day, vws.PATCH_GROUPID, vws.PATCH_TIMEID AS Time FROM VW_Live_Support vws LEFT JOIN W_Patch_Groups wpg ON (vws.Patch_GroupID = wpg.ID) WHERE vws.Deleteable = 'N' AND NVL(wpg.Ignore, 'N') = 'N' AND ((:P70_GROUP > 1 AND vws.PATCH_GROUPID = :P70_GROUP) OR (:P70_GROUP = 1 AND vws.Patch_GroupID IS NULL) OR (NVL(:P70_GROUP,0) = 0)) AND ( INSTR(UPPER(vws.HostName), UPPER(NVL(:P70_SEARCH,vws.HostName))) > 0 OR INSTR(UPPER(vws.ServerStatus), UPPER(NVL(:P70_SEARCH,vws.ServerStatus))) > 0 OR INSTR(UPPER(vws.SiteName), UPPER(NVL(:P70_SEARCH,vws.SiteName))) > 0 OR INSTR(UPPER(vws.Client), UPPER(NVL(:P70_SEARCH,vws.Client))) > 0 OR INSTR(UPPER(vws.CoreHours), UPPER(NVL(:P70_SEARCH,vws.CoreHours))) > 0 OR INSTR(UPPER(vws.Patch_Notes), UPPER(NVL(:P70_SEARCH,vws.Patch_Notes))) > 0 )
Issue is when i select a group from the list I am getting
"report error:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small".
one unusual thing I have noticed here is when I select "All Groups" which returns 0, it is running fine and returning 3700 rows but when I select any group which returns some 10-20 rows I am getting the above error.
can't understand why this is, please help me out.

Tauceef

Thanks alot for your prompt response
Let me add some more into the issue I forgot to add.
It is somewhat similar to what Michael has mentioned in his first post.
Above said report is a Tabular form and there are 3 select lists in it out of which one list is too long (Group list), when I hide it report works for all the groups.
That should have been made clear in the original post. Reports and tabular forms are not the same thing. There's much more that can go wrong on tabular forms, including hitting the LOV size limit of 32KB for a select list item. (Obviously if you hit this limit for a single item then you've automatically hit it the report row limit as well.)
I have explained them about the LOV that when we remove that LOV it works fine but they need that list because it is a updatable value.
As suggested by Michael, I have tried Substr, which also works fine for all the groups.
I would suggest client to have a short name of the groups and use it as a temporary solution.
You should use a Pop-up LOV control for large lists of options. Purely as a usability consideration—irrespective of APEX implementation limits—select lists should only be used in cases where there are a maximum of around 200 options.
Regarding Debugging: I am not getting that option when I run the application as a developer, checked the application properties Debugging option is selected as Yes, don't know why it is not available.
That's not connected to this problem. Open a new thread on that topic if you want to investigate and fix it.
One more confirmation from you guys please, I have also suggested them to upgrate the environment to the latest version, hoping this will resolve the issue, please confirm?
In the latest version also we have same size (32KB) limit or it has been increased?
The 32KB limits for select lists and report rows are not documented but are still present in APEX 4.2 (and in APEX 5.0 to the best of my current knowledge).

Checkbox Item: character string buffer too small (APEX 4.0. - 4.2.)

Hi all,
I'm currently running the Oracle Application Express 4.0.2 on the Oracle DB 11g and thinking about the APEX upgrading to current 4.2. version. We have there quite big application used by the inernal employees so prior I need to test, if the migration will work.
I installed the new server with database and the APEX 4.2. and import the current application. Everything seems to working good except few checkboxes, which returns me the error: "ORA-06502: PL/SQL: numeric or value error: character string buffer too small."
LOV (Source) Code of Checkbox Item:
SELECT email as display_value, id as return_value
FROM users
WHERE <some conditions>;
In the current version 4.0.2. I get the checkbox item (total count of the rows approx. 650), but in the 4.2. I get this "string buffer too small" error and the page could not be rendered (if I add to the same query limitation: "rownum<242" it will display the item).
Could you please help me with this issue? Any idea, what I should set up in the new APEX to get the same results or you see there any limitation, why it does not work in the new version, but in the old version the same SQL works fine?
Thank you all in advance.
Regards,
Tomas.

Why you are hitting this limit in the new instance may be due to differences in data or the database configuration (e.g. character set) rather than changes introduced in APEX.
Is the data exactly the same? Is the database configuration the same? When you limit the number of rows so the checkboxes are displayed and view the page source, is there any difference in the HTML used to render the checkbox form elements between the two versions?
That said, from a usability perspective 650 LOV options is rather a lot, and your application may very well outgrow this limit naturally in any version of APEX as more users as added. It is probably worthwhile thinking about other ways to display these options.

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.

Character string buffer too small problem

hi, guys:
I have a question that may be silly, I got error "ORA-06502: PL/SQL: numeric or value error: character string buffer too small" when I run a query. if I uncomment "and rox.status='Active'" condition, I do not have the error. I guess it is related to some specific rows. I checked online, it looks the length of some varchar2 variable is not enough, but I just cannot find cause. I also notice there might be an error about v_level in the function, I should use number instead of varchar2 type. but after I changed the type of v_level, the error is still there. I would be cautious as this is a legacy system. Could anyone help me on this problem?

I'm not suggesting this is your problem, but
select status
into v_status,
from registration_offender_xref But you have declared
      v_status varchar2(10);Much better to declare things like this
      v_status registration_offender_xref.status%type;That way you know your variable is declared with a proper length, if the column length ever changes ... your code doesn't go kaboom.

ORA-06502 (character string buffer too small) on import application via script

Running apex 4.2.2.00.11
oracle 10.2.0.5
I'm using a script to import my development application to a few production applications.
It worked great on apex 4.1.1, but now I get an 'ORA-06502 PL/SQL numeric of value error: character string buffer too small'
In the command window, I see that the script fails after it starts on the plugins.
My question: is this a bug in 4.2.2?
I could be a incompatible plugin, but how can I found out which plugin?
My script is quite simple:
In a command window I run
sqlplus SCHEMA/PASSWORD@SPIEU10 @_IMPORT_F102.sql
The script is
declare
l_workspace_id number;
begin
    -- determine the workspace id for the workspace FM in the target system
    select workspace_id into l_workspace_id from apex_workspaces where workspace = 'BY_APEX_SHARED';
    -- set the context for the target workspace
    apex_application_install.set_workspace_id( l_workspace_id );
    -- override the original application id 102
    apex_application_install.set_application_id ( 102 );
    -- set a different application name and alias, it should be unique within an APEX instance
    apex_application_install.set_application_alias( 'MY_ALIAS' );
    apex_application_install.set_application_name( 'MY_APP_NAME' );
    -- Use fixed offset
    apex_application_install.set_offset( p_offset => 0);
    -- override the original parsing schema FM with a different value
    apex_application_install.set_schema( 'BY_SCHEMA' );
end;
-- install the original application export, now the values for the workspace

ListAGG throws an ORA-01489 for varchar2 > 4000 bytes
OP has an ORA-06502 --> the IR is running into a 4k/32k limit.
quick solution: wrap USER_COMMENTS ListAGG in a substr( ...., 1, 4000)
Longer solution, use a subquery to modify the comments based on ROW_NUMBER() (ie after nth row, change it to NULL)
with

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.
Regards,
Sunny

Character string buffer too small error in tabular form

Hi Folks,
One of my tabular forms suddenly stopped working out of the blue after 3 months of working perfectly. So I've run into the debug and looks like something went wrong rendering my LOV as below:
     0.16968     0.00328     ...Execute Statement: begin begin SELECT TIME_DISPLAY D, TIME_RETURN R bulk collect into wwv_flow_utilities.g_display,wwv_flow_utilities.g_value FROM TS_HOURS ORDER BY 2; end; end;     4

100
     0.21211     0.00224     report error: ORA-06502: PL/SQL: numeric or value error: character string buffer too smallI've looked around and saw few others having same issues but nothing that's like mine. Could someone please help me find what the issue is? THanks.
I am using Apex 4.1.1

Hi Andre, I have figured out the issue.
You were correct about the 32K limit. However it applies to the whole tabular form not to do with the particular LOV.
I tweaked my other LOV's (with 200 return value) to display fewer and this issue was resolved. I think there wasn't enough left for my 60 row LOV by the time APEX engine got to it which renders after the bigger LOV was rendered.
I think Advisor should have some kind of feature to check forms against 32k limit. Otherwise you wake up one morning and application broke after working 3 months perfectly.

Error in notification - "character string buffer too small"

Hi All,
Hope everyone is doing great...
I have issue with one of the procedure which sends out status email for the reports. Below is the code.
It worked fine from last six months but today it failed because of the length of characters (more reports are added).
The variable "l_an_report" is VARCHAR and it has crossed it limit so gave the below error. Not sure how to handle the report so that it includes all the data.
Also please let me if this is good solution :- Have the report status in excel sheet and attach to the email.
If its fine please let me know how i can achieve this and any prerequisite from network team we need to get?

The error is because you don't check the length of 'l_an_report' until it is already too long.
This code checks the length AFTER adding to it.

You need to test the length of the new string to be added to make sure it won't cause 'l_an_report' to be too long
-- add a new variable in the declare section
v_new_string VARCHAR2(2000);

Wrong forum!!! character string buffer too small problem

Hi,
I'm using a pl/sql procedure which builds a string held by a VARCHAR2 variable, however i've just discovered that in certain situations this string exceeds 2000 characters and i get this error:-

I'm not suggesting this is your problem, but
select status
into v_status,
from registration_offender_xref But you have declared
v_status varchar2(10);Much better to declare things like this
v_status registration_offender_xref.status%type;That way you know your variable is declared with a proper length, if the column length ever changes ... your code doesn't go kaboom.
Cheers,

Character string buffer too small (select list query based LOV)
