Tabular Form: ORA-20001: Error fetching column value: ORA-01403: no data fo

Hi,
Generating some custom error messages with APEX_ERROR.ADD_ERROR at the "Before Header" process point seems to break the display of tabular forms:
http://apex.oracle.com/pls/apex/f?p=26409:2
but work OK for other forms:
http://apex.oracle.com/pls/apex/f?p=26409:1
I've read other posts saying recreating edited tabular forms will fix the error, but this is a brand new tabular form out of the wizard and this is reproducible at will.
Any ideas? Here are the workspace parameters in case anyone would like to take a look:
name: BNTEST, user: DEV, pw: DEV

I looked into collections but I didn't like the thought of the user potentially loosing extensive edits as his session expires.

Correct but how would you resolve this. Data only exists in the browser as long as you wont submit your page.
So even if your session expires and you don't use collections you will still loose your data.
I always prefer to use collections with tabular forms cause this gives the user the possibilety to cancel their changes without that it's been written to the database.
I think that it's better to have no data then faulty data.
I know that it takes a little more effort to use collections but in the end you'll be glad that you did it. ;)

friends i have seen where the error is coming but i am unable to trace out how to increase the size of lov which i have made.
when i am taking display as select list(named lov) it is throwing me the error "ORA-20001: Error fetching column value: ORA-06502: PL/SQL: numeric or value error: character string buffer too small" but if i am taking display as "popup lov(named lov)" under tablular form element under one of the column in the report, it is working properly. but not shwoing the report the way we want it to show. For that reason i want to increase the size of the love which i have made.

Report suddenly showing ORA-20001: Error fetching column value: ORA-06502:

Hi,
Some reports in my applications are suddenly showing:
ORA-20001: Error fetching column value: ORA-06502: PL/SQL: numeric or value error: character string buffer too small
instead iof the data they used to show.
In my development system I can fix this by:
1. changing the column alias in my sql
select 'a' alias1 from dual becomes
select 'a' alias2 from dual
2. SAVE CHANGES
3. change column alias back to original
select 'a' alias2 from dual becomes
select 'a' alias1 from dual
4. reorder columns back to original in the 'report attributes' tab
alias1 is now at the bottom of my colum list - i just bounce it up to column 4 using the up arrows
5. SAVE CHANGES
then everything starts working OK again.
There seems to be nothing wrong with my sql as I can make it works on a new page or after I run the above steps, so I guess something is breaking somewhere but I cannot work out what.
Has anyone else seen this? Does anyone know the cause? Does anyone have a fix for this that does not involve the above steps (plus redeployment to prodcution and all the work that involves)?
I am seeing this on version 2.3 and 3.0.
Thanks,
Martin

Hi Scott,
I think this is want you want (sorry it's not easy to read):
wp.suite_id - Database Column NUMBER - Report Column Based on LOV
wp.project_id - Database Column NUMBER - Report Column Based on LOV
wp.application_order wp_order - Database Column NUMBER - Report Column Standard
lpad(wp.work_package_id,5,'0')||' - '||wp.name wp_name - Database Column NUMBER/VARCHAR2 - Report Column Standard
pt.application_order pt_order - Database Column NUMBER - Report Column Standard
pt.name pt_name - Database Column VARCHAR2 - Report Column Standard
substr(pt.description,1,30) description - Database Column VARCHAR2 - Report Column Standard
pt.application_tier - Database Column VARCHAR2 - Report Column Based on LOV
pt.application_method - Database Column VARCHAR2 - Report Column Based on LOV
pt.TECH_LEAD_ID - Database Column NUMBER - Report Column Based on LOV
This report has no link columns and no derived columns.

Report error: ORA-20001: Error fetching column value

Hi,
I try to build a tabular form with 1 column as "Select List (Query based on LOV)". This select list should display round about 1.100 rows in the LOV ordered by name. So I got the error: report error:
ORA-20001: Error fetching column value: ORA-06502: PL/SQL: numerischer oder Wertefehler: character string buffer too small
When I try tho define this column as Popup LOV (Query based LOV) only the the ID of the attribute and not the display value appeares in the row. The LOV it self displays the display number and not the the ID. I want to see the display value in the column of the particular row and the LOV and return the ID to the record by insert or update as it is normal in LOVs of form regions.
This lot of rows in the LOV is necessary because it is a part to develop formulas like (number_of_acquisitions - number_of_old_parts)/100 or so. The most formulas will be more complex. In the database there should only be the ID as reference to the attributes.
Please help me to display the attribute bases on LOV in every particular row.
Thank you
Siegwin

In Apex 4 there is now a column type "Popup Key LOV (named LOV)" which is exactly what you are looking for.

ORA-20001:Error fetching column value:Query must begin with SELECT or WITH

Hi all,
I have implemented an application with a master-detail form using Apex 3.1.2 and I imported that to Apex 3.2 on different server. Everything else seems to be fine except when I add detail record (clicking on Add Rows), I am getting following error.
=================
report error:
ORA-20001: Error fetching column value: ORA-20001: Query must begin with SELECT or WITH
====================
Both the databases have same version 10gR2. I didn't make any change after importing it as well. Can someone let me know what could be the issue? Thanks in advance.

May we know your first name?
Can you put the application in your workspace on apex.oracle.com so we can take a look?

Classic Report - report error:ORA-20001: Error fetching column value

Hi,
In Apex 4 I have created an SQL report which errors with ORA-20001: Error fetching column value: ORA-01403: no data found.
It works fine if I hard code the start and end dates but fails when I use page items as parameters.
I call a stored function as below:
DECLARE
l_sql VARCHAR2(4000);
BEGIN
SELECT ICDB_PCT_MRSA_POS_REP(v('P40_NEWSTARTDATE'),
v('P40_NEWENDDATE'))
INTO l_sql
FROM dual;
RETURN(l_sql);
END;
although I have used the :P40_NEWSTARTDATE form too, with the same result.
Any suggestions will be welcome.
Thanks,
Chris

Hi Chris,
have you debugged if ICDB_PCT_MRSA_POS_REP is raising the no-data-found error or if it's the actual SQL statement which got returned?
Comment out the call to ICDB_PCT_MRSA_POS_REP and return a hard coded SQL statement with
return 'select [... here comes a sample sql statement returned by ICDB_PCT_MRSA_POS_REP]';to rule out that ICDB_PCT_MRSA_POS_REP is raising the error.
BTW what is the purpose of the select from dual? Just call the ICDB_PCT_MRSA_POS_REP directly like
return ICDB_PCT_MRSA_POS_REP(:P40_NEWSTARTDATE, :P40_NEWENDDATE);Regards

Master Detail report report error: ORA-20001: Error fetching column

Hi All,
I am a newbie in apex and try to create a master detail form, where the detail is displayed as a report.
After inserting a new row in the master form i like to create the detail. It displays then ORA-01403: no data found
I also insert in the database table the details. If i want to edit then it shows the following report error:
ORA-20001: Error fetching column value: ORA-01403: no data found
Can anyone help me, because i am struggling for a week with this problem.

Your problem seems to be related to the usage of primary keys. You have to look into that and get more details.

ORA-20001 error when creating Tabular Form or Form and Report

Whenever I try and add a Tabular Form or Form and Report to my application i am getting the following error at the end of the Wizard.
ORA-20001: Unable to create updateable report. ORA-20001: Error creating shortcut id="" ORA-00001: unique constraint (APEX_030200.WWV_FLOW_SHORTCUT_IDX1) violatedIt's not a problem I have seen when building other apps and clearly I have managed to corrupt this application somehow.
I have loaded the problem onto apex.oracle.com for those that have access. The application number is 20325.
Any help would be very much appreciated.
Cheers Shunt

Thanks! Never thought of that.

Ora -20001 error coming while updating from a tabular form

Hi
I have a tabular form , which updates a table in the database.
Whenever I update the record first time I getting an error as
Error in MRU internal routine ORA-20001.Error in MRU:row=1,
ORA-1403 no_data_found, update abc.sale_forcast_temp set "PK_ID"=:b1,"W27"=:b2
Error unable to update process
But when I press Ok return to the form and then again try to update , records gets successfully updated
Regards
Shashi

Kamal,
This will be the pseudocode.
Procedure A()
select * from EMP bulk collect into records_array; --Of type RECORD_ARRAY
batch_count = (records_array.length) / batch_size;
--batch_size is say 5000 rows and batch_count is the number of batches
for i in 1..(batch_count+1)
B( records_array);
C();
commit;
Procedure B(records_array in RECORD_ARRAY )
INSERT /*+PARALLEL(EMP_DUMMY, 2) */
INTO TABLE EMP_DUMMY
SELECT * from TABLE(CAST(records_array as RECORD_ARRAY) ;
Procedure C()
Other operations which include reads on the EMP_DUMMY table;
This is the top view of how it looks like. Actually the Select statement for the insert statement is very complex and I do a join on the records that are being passed in by casting it into a table. This query is taking about 40 minutes for 10,000 rows in the records_array. I need to parellelise this query because each row of the records_array yields a different row for the EMP_DUMMY table.
I hope that I made it clear for you.
Can you also tell me if procedure C in which I shall be doing a read on the EMP_DUMMY table, has any affect of the parallel insert
Thanks for your help.

Help Needed: Facing the error ORA-01406: fetched column value was truncated

Hi Everyone,
When I run a particular PL/SQL query using Oracle 9i ODBC driver, it is working fine and fetching me the desired results.
However, when I run the same query using the Oracle 10g ODBC driver, I am getting the error: ORA-01406: fetched column value was truncated.
I have checked all the fields of the table and they are well within the allowable limit.
Can you please let us know what needs to be done to resolve this issue?
Thanks and Regards,
Sudhindra

Well it's obviously a problem with the client software. Doesn't Datastage have some way of configuring these things?

Weird ORA-01406: fetched column value was truncated error for SELECT query

DB version:10gR2
When one of our application fires the below query, we get
ORA-01406: fetched column value was truncatederror.
select     trk_dtl,
     trk_type,
     trk_id,
     trk_desc,
from     shp_dtl
where     shp_type = 'HN'
and     shp_type = 828;The documentation says
Cause:In a host language program, a FETCH operation was forced to truncate a character string. The program buffer area for this column was not large enough to contain the entire string. The cursor return code from the fetch was +3.But when the application is pointed to an identical schema in the same instance, we don't get this error. So, this has got nothing to do client application as the documentation says.
Any idea what other possibilities are there?

ORA-01405: fetched column value is NULL

Hi All,
I am using OWB 10gR2 and DB 10gR2. I am getting the following error while executing the mapping,
ORA-01405: fetched column value is NULL.
I have used NVL function for the measure columns, but the problem is not solved.
Can anybody please tell me solution,
Thanks in advance,

Hi Siva
It may be that you've taken care of null value in just one place and now, the error is coming
from somewhere further down the line.

Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-01779:

I have a tabular form based on a view like:
select
t1.id,
t2.network_id,
t2.month_id,
t2.icp_ic,
t1.status,
t1.disc_comment
from
table1 t1,
table2 t2
where
t1.month_id (+) = t2.month_id and
t1.network_id (+) = t2.network_id and
t1.icp_id (+) = t2.icp_id
id is a surrogate key of table1 and there is a trigger to populate this on insert. There is also a unique index on table2 (month_id, network_id, icp_id). When I change the disc_comment column through the form and try to save I get an error:
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-01779: cannot modify a column which maps to a non key-preserved table
If I take out the outer join, it works fine. The problem is table1 will not have a row for every row in table 2, hence I need the outer join. Any ideas how I can get around this problem?
Regards
Sadanand

Hi Andy,
Yes I am paginating the form and I am not getting a set of blank rows. What I mean by next set of records is - if the page is showing rows 11 to 20 and I enter a comment against row 15 and save, the form inserts the comment into the table via the INSTEAD OF trigger and the page automatically refreshes with rows 21 to 30 from the query. On the other hand, if I click Prev link and redisplay rows 11 to 20, change the comment and click on Save, the form updates the comment and refreshes the page with rows 11 to 20. If I update the comment again, it redisplays page with rows 11 to 20 and this is the behaviour I desire when I insert data. Remember that I am using outer join, so there will be a mix of inserts and updates of data. I hope my explanation is clear. I have tried removing the tabular form region and starting from scratch but that hasn't helped - maybe I will drop the page and recreate it.
As for checksum error, you are right - it disappears after I logout and login again.

Sadanand

Error in mru internal routine: ORA-20001: Error in MRU: row= 0, ORA-20001:

Hi, I'm using HTMLDB version 1.6.0.00.87 on a DB 10.1.0.3.0.
I'm creating a Tabular Form to perform update operations on multiple rows in a database table.
The table is in a schema outside of the HTMLDB schema and my application works.
If I substitute my table with a synonym (outside of the HTMLDB schema) pointing to another table (outside of the HTMLDB schema), the select works fine but when I try to update records an error occurs:
0.05: Branch point: BEFORE_PROCESSING
0.05: Processing point: AFTER_SUBMIT
0.05: ...MULTI_ROW_UPDATE (AFTER_SUBMIT) #OWNER#:CSTCMP:T$NCMP:T$CPCP
0.08: Show ERROR page...
0.09: Processing point: AFTER_ERROR_HEADER
0.10: Processing point: BEFORE_ERROR_FOOTER
Error in mru internal routine: ORA-20001: Error in MRU: row= 0, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum = "1F2F93F97DFD18A9D69960FCD28AF6EF", item checksum = "A884FA378C851786DDFE3A33709CB23C"., update "WS_T1"."CSTCMP" set
If I perform with SQL the update on the synonym, it works.
I only have a browser connected to the application and I'm not locking the table.
I don't think this is correlated with
Re: Error in mru internal routine (HTML DB BUG?)
What do you think about?
Thanks in advance.

To look into what? You probably modified your tabular form by adding a column and you didn't take care of the column source.
