ORA-06502 character string buffer too small error

We trying to insert a string of more then 500 character from our VB.net application (uses ODP.net), its giving ORA-06502 character string buffer too small error.
Kindly help us on this.
OS version: AIX 5.1 (IBM/AIX RISC System/6000)
Oracle Database version: 9.2.0.1.0

Just for reference and to close the loop, I found the fix to this problem (quite by accident).
The problem turned out to be a bug in the apex listener, which in some cases ended up doing a divide by zero, which caused the problem.
This is listed as a known bug, and a fixed listener is available.
Once I installed the fixed listener, problem solved!

ORA-06502 character string buffer too small, works in query not procedure

The following query works prefect as a single query:

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.

Report error:ORA-06502:character string buffer too small. urgent!!

Hi guys,
My APEX version is 3.0.1.00.08, my application run on my test environment, but on PROD environment, it raised the error:
report error:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
In this page, on the left is a tree, the right side is a tabular form, when I click one tree node, it will pass the current node id to the form and the form will display the children data. When I click some tree node, it will raise the ORA-06502 error, but when click some other nodes, it is correct. I don't know why. And on my test environment, it has no this error, the test environment has same version with prod environment, only has less data in database. Could you help me???
I searched in forum, someone says it's LOV problem, if it's LOV problem, all the nodes should have error, why click some nodes are ok?
Thanks !
Jessica

I don't think it is related only to the number of rows but also to the content of the rows. So, counting only the number of rows doesn't say anything about if it is going to work or not. My question: can't you filter those entries? Making a choice between 250 entries in a tabular form isn't a simple task. Using popup-key LOV instead would also be a solution. However, if you use popup-key LOV be aware of the fact that you need two index numbers for those.

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

WWV_FLOW_WORKSHEET_CONDITIONS - ORA-06502 character string buffer too small

Hi,
I am currently working on a application that can upload CSV files inside many tables. Since I hate reinventing the wheels, I have decided to reverse engineer APEX and APEX APIs that are used by the SQL Workshop to upload CSV files to a single table. Since this feature was tested many times by many developers around the world, I know I can trust the code. If in a future release of APEX those packages are modified, I'll have to update my abstraction layer to call my own packages instead of APEX packages. (This is not an issue for our team.)
First Step
Use apex_040000.wwv_flow_load_data.create_csv_collection to create an apex collection with the first 20 rows of the csv file. At this step, we can validate the format of a sample of the file without loading all rows of the csv file.
Second Step
Use apex_040000.wwv_flow_load_data.load_csv_data to upload all rows of the csv file inside a table.
Third Step
Do whatever you want with the data inside the table. (i.e.: Send the data into multiple tables...)
Here's my problem..._
After the first or second steps, I display the data using interactive reports. I want to highlight every cells containing "invalid" data. I use apex_040000.wwv_flow_worksheet_api.add_or_update_highlight. When I have too many invalid cells, the IR doesn't show at run time, and you can see ORA-06502: PL/SQL: numeric or value error: character string buffer too small on the page.
I would like to know the limitations of IR using the table WWV_FLOW_WORKSHEET_CONDITIONS. Is there a way to create many highlight conditions inside a single row of WWV_FLOW_WORKSHEET_CONDITIONS ? I want to find the best approach to add hundreds of conditions.
Thanks

'ORA-06502 character string buffer too small' when called from C# app

I have researched this problem and checked my variable sizes over and over again. I have tested the procedure within the Oracle Express environment and it works fine; HOWEVER, when the procedure is called from my C# app it produces the ORA-06502 error.
The stored procedure signature looks like this...
create or replace save_new_project (p_custorgid in number,
p_title in varchar2,
p_AOIName in varchar2,
p_description in varchar2,
p_receiveddate in date,
p_deadlinedate in date,
p_startdate in date,
p_createddate in date,
p_createdby in varchar2,
p_projectid out number,
p_statustypedescrip out varchar2)The OracleParameter in my C# app for the last out param is defined as such...
cmd.Parameters.Add(new OracleParameter("p_statustypedescrip", OracleDbType.Varchar2, 30, ParameterDirection.Output));As I said at the beginning of this post, the procedure works fine in the Oracle environment. So why is it not working by simply calling it from C#? I've tried changing the OracleDbType to CLOB which eliminates the error but it returns a bizarre result. It returns this string, "Oracle.DataAccess.Types.OracleClob". WTH?!!
Since CLOB doesn't really work either I switch back to Varchar2 and specify a size of 5000 (in the database the field I am querying is defined as Varchar(30)). I still get the ORA-06502 error.
I am clueless as to what the problem is. It should work and it does if I run a series of SQL statements in an Oracle SQL Command window. The test that works fine looks like this...
declare
v_projid projects.projectid%type;
v_statustypedescrip projectstatustypes.type%type; /* this is a varchar(30) */
begin
save_new_project(2, 'Some input text goes here', 'More input text', 'And more again','26-APR-2007','26-APR-2007','26-APR-2007','26-APR-2007','users name as inpujt text here',v_projid,v_statustypedescrip);
dbms_output.put_line('v_projid = ' || v_projid);
dbms_output.put_line('v_statustypedescrip = ' || v_statustypedescrip);
end;But calling save_new_project from C# throws ORA-06502. It identifies line 40 of my stored procedure. This is line 40...
p_statustypedescrip := v_statustypedescrip;

Problem solved!!!
I don't know why this worked but it did. I changed how I declared the output parameter in my C# app. I used to have it on one line like this...
cmd.Parameters.Add(new OracleParameter("p_statustypedescrip", OracleDbType.Varchar2, 30, ParameterDirection.Output));but then I changed it to multiple lines like this...
OracleParameter prm11 = new OracleParameter();
prm11.ParameterName = "p_statustypedescrip";
prm11.OracleDbType = OracleDbType.Varchar2;
prm11.Size = 30;
prm11.Direction = ParameterDirection.Output;
cmd.Parameters.Add(prm11);I don't know why it works this way but it does and that's all I care about.

Ideas for working around ORA-06502: character string buffer too small on Interactive report

Hello,
This is for Apex 4.2. We are trying to create an interactive report. The report is for something similar to a time tracking application. We are trying to concat a comments column while summing the hours. For example,
select TASK_NAME, sum(HOURS), to_char(XMLAGG(XMLELEMENT(E,E.COMMENTS || ' : ')).EXTRACT('//text()').getstringval()) USER_COMMENTS from ......
This query works fine if we are looking only at a 1 week window. The issue we are experiencing is that when we expand the range of the query to include data from 3 months, we hit ORA-06502 in the interactive report. If we remove this column from the Interactive report, then the report runs fine.
Does anyone have any ideas on how we might be able to work around this? I am guessing we are hitting the 32k limit on the report. Ideally we would just show the last X number of comments and then have a link to view all the comments
Any help would be appreciated
Thanks
Mike

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.

Character string buffer too small Error !!!

Hi friends,
I have a procedure
procedure sam(x varchar2,id number,val varchar2)
as
c number;
begin
if(x = 'data') then
select count(*) int c from emp where ID = id;
end;
if(x = 'basic') then
select count(*) int c from emp where ID = id;
end if;
if(c = 0) then
val:='Yes';
else
val:='No';
end if;
end;
There is no problem with the procedure
Code that calls from C#.net
OracleCommand cmd = new OracleCommand("TOOLS.CheckPrevData",(OracleConnection)con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("x",OracleDbType.Varchar2,System.Data.ParameterDirection.Input);
cmd.Parameters["Filetype"].Value = "data";
cmd.Parameters.Add("id",OracleDbType.Int32 ,System.Data.ParameterDirection.Input);
cmd.Parameters["Product_ID"].Value = 123456789;
OracleParameter param = cmd.Parameters.Add("Val",OracleDbType.Varchar2,System.Data.ParameterDirection.Output);
cmd.ExecuteNonQuery();
When i execute the c# code it throws the below exception at cmd.ExecuteNonQuery()
ORA-06502: PL/SQL: numeric or value error: character string buffer too small ORA-06512: at "PROC", line 910 ORA-06512: at line 1
Someone please help me !!!!!

Hi,
In the procedure I see this:
procedure sam(x varchar2,id number,val varchar2) <=== all "in" parameters (the default)In the C# code I see this:
cmd.Parameters.Add("Val",OracleDbType.Varchar2,System.Data.ParameterDirection.Output); <==== Declared as "output"Perhaps something like the following will help:
procedure sam(x varchar2,id number,val OUT varchar2)Hope that helps a bit,

Bug: Report Column based on LOV character string buffer too small error

When using a column type of "Display as Text (based on LOV, does not save state)" with a result set that is rather large causes a character or string buffer too small oracle error.
See the below page for an example.
The example page below has a single report off a table called "HUGE_TABLE" which has two columns: display and code
Code contains a number between 0 and 100000.
Display contains the number in code appended to a block of text.
When I display the report with no Display As Text (based on LOV does not save state) it displays fine.
If I make the "Code" column display as text based on LOV and make the LOV
"SELECT display, code FROM huge_table"
I get the error you see on the page.

Thanks.

Thanks for your help Scott.
So from what I've gathered from my own tests and the discussions you linked me to the LOVs based on SQL queries are being converted into "static LOV" strings before being used.
As such they are limited to the PL/SQL VARCHAR2 max size of 32767
Which means given the static reduction of the string 'STATIC:' that we have 32760 characters left.
Which is where your SUM( LENGTH( display ) + LENGTH( return ) + 2 ) comes in.
In short, if:
sum( length( display ) + length( return ) + 2 ) + 7 > 32767
would evaluate to true then you have a problem. :)
I'll use this to track down my problems and switch them over to inline queries.
Thanks.
Cheers,

ORA-6502 Character String buffer too small

Stored procedure call from C#. Ref cursors are no problem but trying to return Varchar2 is a bit of a puzzle. Just the simple code fragment below blows with ORA-6502.
PROCEDURE getjdt2 (X OUT VARCHAR2) IS
BEGIN
X := 'TEST RETURN VARCHAR2';
END;
OracleCommand cmd = new OracleCommand ("GETJDT2", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("param1",OracleDbType.Varchar2);
cmd.Parameters[0].Direction = ParameterDirection.Output;
OracleDataReader reader;
reader = cmd.ExecuteReader();
reader.Read();
Console.WriteLine ("Val: {0}", reader.GetString(0));

Never mind. A bit more research and I figured it out.

"ORA-19011: Character string buffer too small" doing select xmlelement???

Apparently there is a 4K limit on the amount of XML that can be produced doing a select with SQL/XML syntax, or so it appears. That is pretty disappointing. It makes this feature uselful only for demos. 256K would be a much more realistic limit for real-world applications.

Is there any work around for this when I was using XPath I was to able use xmlsequence and come around this. But when I am using xquery execution seems to be slow, I do not want to xmlsequence and further reduce the performance.

ORA-19011: Character string buffer too small

my query
select to_clob(xmldata) from ei_output where id=1my java code...
       //load jdbc driver
            Class.forName("oracle.jdbc.driver.OracleDriver");
            // create connection
            c=DriverManager.getConnection(UI.jTxtConStr.getText(),UI.jTxtUsr.getText(),UI.jTxtPsw.getText());
            //create statement
            Statement stmt=c.createStatement();
            ResultSet rs=stmt.executeQuery(UI.jTxtAreaSQL.getText());//resulset pe baza a ceea ce e in TextArea din UI
            //get the result
            while(rs.next()){
                is=rs.getClob(1).getAsciiStream();
            }I need the ascii stream in order to do a transform provided by apache xalan...
what can I do about it? how can I get the ascii stream of the xmldata(xmltype)?

Maybe a possibility would be to let the query return an XMLType instead of a CLOB or VARCHAR2 and then you can do the transformation on the server in Java instead of on the database. We tried something similar for a PL/SQL procedure:
public Document getXML() {
try {
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
java.sql.Connection connecton =
DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:ORCL",
"scott", "tiger");
oracle.jdbc.OracleCallableStatement statement =
(oracle.jdbc.OracleCallableStatement)connecton.prepareCall("BEGIN \"WEBSERVICE\".TEST_XML(:1 ); END;");
statement.registerOutParameter(1, OracleTypes.OPAQUE,
"SYS.XMLTYPE");
statement.executeUpdate();
//Object out = statement.getObject(1);
XMLType xml = XMLType.createXML(statement.getOPAQUE(1));
statement.close();
System.out.println("out: " + xml);
return xml.getDOM();
} catch (Exception e) {
e.printStackTrace();
return null;
The WEBSERVICE.TEST_XML procedure returns data as an XMLType object.

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.
