ORA-06502 PL/SQLnumeric or value error character to number conversion error

Hi,
I have written report in FastReport and I am using "Oracle Provider for OLE DB" for Oracle connection.
I have seen that my report throws oracle exception in some machines , so I analysed my PL/SQL and saw that problem occurs in "TO_NUMBER" function. (if i remove it exception does not occur)
However, same report works fine in another machine with the same data (same oracle provider version).
What can be the problem? What can be the dependence?
Thanks in advance
Elshan
p.s. Oracle provider version is 11.2.0.2.0

Hi ,
the reason you are gettin this error is ecause sometimes in your data you are trying to convert a character to a number. When you say it works fine in other machine dos it mean for the same data set or a different data?
If you thing that you data may conatin a character and you still need to use TO_NUMBer than you should chack the data before converting and if it is a character than you should no do the conversion.
you can use this link to chek numeris or non numeric
How to check if a field is numeric?
thanks

Poltergeist in my code?... ORA-06502: PLSQL: Numeric or value error

Hi all!
I am experiencing a very strange problem,
i have the following code:
BEGIN
INSERT INTO BD_SESSION_GROUP
(CDSESION, NM_ANO, CD_CENTRO, CDGRUPO, FCSESION, ITREALIZADA)
VALUES (:DATOS.CDSESION,
:GLOBAL.CURSO_ACADEMICO,
:GLOBAL.COD_CENTRO,
:DATOS.CDGRUPO,
:DATOS.FECHA_EVAL,
REALIZADA
EXCEPTION
WHEN DUP_VAL_ON_INDEX THEN
BEGIN
     message('*1');
     message('*2');
     message('*3');
UPDATE BD_SESSION_GROUP
SET ITREALIZADA = REALIZADA,
FCSESION = :DATOS.FECHA_EVAL
WHERE NM_ANO = :GLOBAL.CURSO_ACADEMICO
AND CDSESION = :DATOS.CDSESION
AND CD_CENTRO = :GLOBAL.COD_CENTRO
AND CDGRUPO = :DATOS.CDGRUPO;
-- GO_ITEM('DATOS.IMPRIMIR');
EXCEPTION
WHEN OTHERS THEN
MENSAJE (SQLERRM || ' No se ha Podido Actualizar BD_SESSION_GROUP');
END;
WHEN OTHERS THEN
MENSAJE (SQLERRM || ' No se ha Podido Insertar en BD_SESSION_GROUP');
END;
I have checked that it enters in the WHEN DUP_VAL_ON_INDEX exception, and it shows the code
message('*1') and then message('*2');
this is correct, but the problem is that it doesn't show message('*3');
In fact, it shows the error "ORA-06502: PLSQL: Numeric or value error".
And more, i have checked that it doesn't matter what code you put above UPDATE BD_SESSION_GROUP...
it always crashes with the same error...
it don't really know what to do, because i have tryied using synchronize...
If someone can help me, it would be very apreciated,
thx in advance!!!

Given the message procedure and the mention of "synchronize" I'm assuming this is code from an Oracle Form. You might want to post this in the Forms forum as it could be more of a Forms question than a PL/SQL question.
Where are you seeing the error? On the message line? Do you have ON-MESSAGE or ON-ERROR triggers?

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,
'APPLICATION_PROCESS=Set_Multi_Items_Tabular',0);
if(pValue){
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);
if(l_Opt_Xml.firstChild){
var l_Value = l_Opt_Xml.firstChild.nodeValue;
}else{
var l_Value = '';
if(l_El){
if(l_El.tagName == 'INPUT'){
l_El.value = l_Value;
}else if(l_El.tagName == 'SPAN' && l_El.className == 'grabber'){
l_El.parentNode.innerHTML = l_Value;
l_El.parentNode.id = l_ID;
}else{
l_El.innerHTML = l_Value;
get = null;
</script>

I did modify Denes' code from table: my_book_store and columns: subject, price, author to match my sample table: EMPLOYEES and columns: FIRST_NAME, LAST_NAME, and EMAIL.
Am I missing some steps? Please advise and thank you in advance.
Candice

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.

Quote Form: Repeatively Query gives Error:ORA-06502: PLSQL numeric or value

Hi,
I am trying to query the sales order form (in Order Management) with the order number.
Steps to Reporduce:
Without closing the sales order form, query the same/different order number repetively again and again (upto 30 times) in sales order form and i am getting the following error. It might be due to the form buffer error i think, but i want to know how to resolve this issue.
ORA-06502 : PLSQL : numeric or value error
I have suggested the workaround as closing the form after querying every 15 times, but the customer needs a permanent fix by querying continously without closing the form, they want to query the record. Please suggest how to resolve this issue.
Thanks

The errors comes when in variable or fields data is coming more than the maximum length it.
e.g
declare
vcheck varchar2(1) := 'ABC'; ---Errorplz share your code where you feel the problem might occurring usually POST-QUERY trigger.

Error ORA-06502, numeric or value error character to number conversion

I have been trying to create an email including data from a table as part of the body. Whenever I try to send it, I get an error ORA-06502, numeric or value error, character to number conversion. If I take out the part referencing the table, the email will go without error, but if I put it back in I get the error.
There is the code:

This is important to my company to be able to put this data into an email. If anyone can help me, I would greatly appreciate it. Thank you in advance.

Lets isolate the erroring line by running the code in debug mode and adding some debug lines at various stages in the code
Apex has a builtin function named wwv_flow.debug which can print messages to the debug stack and would be visible when the page is run in debug mode.
DECLARE
v_email_body CLOB;
v_from_email_address VARCHAR2(100) := v('APP_USER');

Only INVALID_NUMBER exception is handled and also VALUE_ERROR should be handeled. You can resolve it by handling VALUE_ERROR exception or by adding WHEN OTHERS as I did in following example.

ORA-06502: PL/SQL: numeric or value error: character to number conversion

Hello,
I am new to Oracle Apex so I decided to read and do the tutorials that are on the apex.oracle.com site.
Now I am at the tutorial 6: How to Work with Check Boxes of the Advanced Tutorials.
At a certain point you have to add a new radio button.
At the Item Source Value you have to add SELECT 'Y' FROM DUAL WHERE :P2_LIST_PRICE*0.75=:P2_MIN_PRICE.
But when I try to create the item, I keep getting the following error:
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
Error creating item.
Does anybody know what could be the problem.
Thanks in advance.

Here I m passing a string variable to pass the select statement for the ref cursor.
There seems some problem in the substr conversion in the statement.
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
But when i run as a independent staement passing real values in the place of placeholders
i get the result right.
The *:PERIOD_NAME* format is *'Jan-2009-10'* .
And I need to pass the *:PERIOD_NAME* to the query as *'Jan-09-10'*
Pls suggest.

Numeric or value error: character to number conversion error

I'm having problems inserting a value from a date picker field (DD-MON-YYYY HH MI )
i'm submitting this value to a packaged procedure that accepts this field as VARCHAR2 .
on the insert, i do a to_date( P_DATE, 'DD-MON-YYYY HH:MI PM' )
and i get the numeric conversion error.
If I change the to_date on the procedure side, I get the :could not read the end of the format mask - which I've found threads about on this site.
I've tried using HH24 and different formats, but I get one of the two above errors on the insert.
If I don't fill in the datepicker field at all, it works fine.
help is appreciated !
Bill

Re: Error, numeric or value error: character to number conversion error

Can someone please please tell me why I'm getting this error and what I'm doing wrong? It looks like a simple error, "numeric or value error: character to number conversion error".
My code is as follows:
string connectionString = WebConfigurationManager.ConnectionStrings["DEMO_TEST"].ConnectionString;
OracleConnection con = new OracleConnection(connectionString);
OracleCommand cmd = new OracleCommand("DEMO.PKG_LOCATION_TYPE.INS", con);
cmd.CommandType = CommandType.StoredProcedure;

cmd.Parameters["@P_DESCRIPTION"].Value = "Test_Description";
cmd.Parameters.Add(new OracleParameter("@P_NAME", OracleDbType.Varchar2, 6));
cmd.Parameters["@P_NAME"].Value = "Test_Name";
cmd.Parameters.Add(new OracleParameter("@P_LOCATION_TYPE_CD", OracleDbType.Decimal, 4));
cmd.Parameters["@P_LOCATION_TYPE_CD"].Direction = ParameterDirection.InputOutput;
con.Open();
try

Are the parameters in your procedure in the same order as they are created in this code? Oracle command works by position unless you change it to be BindByName.
Failing that you seem to have defined a parameter (P_NAME) to have a length of 6, and are then setting it's value to a string with a length of 9.
Also the in/output parameter is defined as type decimal. Is this correct? It is defined as InputOutput but you don't assign it any value.
If these suggestions don't help then perhaps if you post the stored procedure you might get some more ideas.

PL/SQL: numeric or value error: character to number conversion error in TRG

Hi,
I've got strange issue with one trigger which during update of table reports (DB is 9.2.0.8):
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
ORA-06512: at "UDR_LOG", line 345
ORA-04088: error during execution of trigger 'UDR_LOG'but line 345 is:
END IF;
so its kind of strange
the code looks like
343 IF nvl(to_char(:old.PKD_ID),'''') <> nvl(to_char(:new.PKD_ID),'''') THEN
344 v_zmn := v_zmn || 'PKD_ID''' || to_char(:old.PKD_ID) || '''' || to_char(:new.PKD_ID) || '''';
345 END IF;
so its concatenation not to_number usage .error is triggered by update statement on any column .
I'm sorry I cant provide You with whole trigger code .
So if You could only recommend any investigation method that would be great .
Regards
Greg

Hi, Greg,
When there's an error in a trigger, the line numbers in the error messages are relative to the first DECLARE or BEGIN statement; often, that's a few lines after CREATE OR REPLACE TRIGGER. Post a few lines after what you already posted.
If you can't find the error, then create another table for testing this, and create a smaller trigger on that table, which does only enough to cause the error. Then you'll be able to post the complete trigger, and the code needed to re-create the problem.

Character to number conversion error during uploading csv

hi
I have a question regarding oracle application express.
I want to upload the csv data to the database using apex application.
I used a code from otn but it does not work to the number datatype value..
It gives an error like number to charcter conversion error am not able to resolve it.
I also use TO_NUMBER functions to convert but it doesn't works..please help me out..
Following code I used to upload the data:
DECLARE
v_blob_data BLOB;
v_blob_len NUMBER;
v_position NUMBER;
v_raw_chunk RAW(10000);
v_char CHAR(1);
c_chunk_len number:= 1;
v_line VARCHAR2 (32767):= NULL;
v_data_array wwv_flow_global.vc_arr2;
v_rows number;
BEGIN
delete from chktable;
select blob_content into v_blob_data
from wwv_flow_files
where last_updated = (select max(last_updated) from wwv_flow_files where UPDATED_BY = :APP_USER) and id = (select max(id) from wwv_flow_files where updated_by = :APP_USER); v_blob_len := dbms_lob.getlength(v_blob_data); v_position := 1; WHILE ( v_position <= v_blob_len ) LOOP v_raw_chunk := dbms_lob.substr(v_blob_data,c_chunk_len,v_position);
v_char := chr(hex_to_decimal(rawtohex(v_raw_chunk)));
v_line := v_line || v_char;
v_position := v_position + c_chunk_len; IF v_char = CHR(10) THEN v_line := REPLACE (v_line,',','~'); v_data_array := wwv_flow_utilities.string_to_table (v_line,'~'); EXECUTE IMMEDIATE 'insert into SRS_CC_MI_DATA(OUTAGE,TAR_#,CUSTOMER_NAME,RECEIVED,RESOLUTION_TIME,SEVERITY,PRIORITY)
values (:1,:2,:3,:4,:5,:6,:7)'
USING
v_data_array(1),
v_data_array(2),
v_data_array(3),
v_data_array(4),
v_data_array(5),
v_data_array(6),
v_data_array(7);
v_line := NULL;
END IF;
END LOOP;
END;
my table contains:
"OUTAGE" VARCHAR2(4000),
"TAR_#" VARCHAR2(4000),
"CUSTOMER_NAME" VARCHAR2(4000),
"RECEIVED" VARCHAR2(4000),
"RESOLUTION_TIME" VARCHAR2(4000),
"SEVERITY" VARCHAR2(1),
"PRIORITY" VARCHAR2(4000) NOT NULL ENABLE
i need to make last two rows number type..
it works fine if it is varchar2 but not with number type..
plz help out

Hello,
>> "PRIORITY" VARCHAR2(4000) NOT NULL ENABLE
What is the valid values of this column that you need to use varchar2(4000)? Are you sure this column include valid numbers?

Arie.

Pages crash in Portal (ORA-06502)

Hi! I have a little problem with Portal pages. Sometimes a page with its subpages crashed with follow error : " ORA-06502 PLSQL: numeric or value error".
Does anybody know why this happaned?

Hi Mark
Sorry for the delay. Not sure I can provide the immediate comfort that you're looking for either.
What I can say is that dropping and recreating the Text indexes almost certainly won't affect this.
We'd need more details to figure out what's going on here. The best way to do this is for you to contact Oracle Support. They should be able to help you to get the problem solved.

Report error:ORA-06502: PL/SQL: numeric or value error: character to number

The oracle application express environment is created by installing the HTTP Server on the windows server and the application express 3.2.1 components on the 11.1.0.7 oracle database on UNIX. The installation is successfully and have not seen any issues during the installation. After completing all the steps, when tried to login and click the application builder or workspace components, I see the error message
report error:ORA-06502: PL/SQL: numeric or value error: character to number.
This error message is seen on most of the pages when trying to accessed and not able to understand the reasons behind it. Its a brand new environment setup and not even presented to developers to test it.
Below error message is always seen when trying to access most of the components like application builder, schema comparison and some other tabs. Please advice

Edited by: user589320 on Jun 9, 2011 5:17 PM

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.
* If this answer is helpfull or correct then please mark it and grant the points.

ORA-06502: PL/SQL: numeric or value error: character to number error

Hello Gurus,
I keep getting the following error:

It happens on wizard generated tabular form.

END IF;
END LOOP;
END;I am trying to update venue_prsntd_qtr. I have commented everything else out to see if I can limit where the error is coming from.
qtr is a number field in the database. I have gone back and forth with variable type in the code and still get the same error.
I am using oracle db 10g, apex 3.2.1
Thanks
Mary

Hi,
I am guessing that apex_application.g_f05 is a date field. If that is the case, you need to use to_date() before using to_char(). For example:
SELECT to_char('01-jan-10', 'MON') FROM dual -- Error!
SELECT to_char(to_date('01-jan-10'), 'MON') FROM dual -- Ok!
I hope this helps.
