Intersection Shuttle: wrong row deleted

JHS 10.1.3.1.26
I created an intersection shuttle and noticed that when I removed for example the 5th row in the shuttle and saved that mutation (delete row from intersection table), in fact the first row (from the viewobject) was deleted.
I found that method "processUnselectedIntersectionShuttleRow" in class "JhsApplicationModuleImpl" does the job.
Should there be a "intersectionVo.executeQuere()" between the lines
intersectionVo.applyViewCriteria(vc);
Row intersectionRow = intersectionVo.first();

Frank,
That's correct, we already fixed this for the next release.

ChnAreaDel deleting wrong rows in a string channel

I am trying to write a script in DIAdem 2010 SP1 to delete the first row of a group that contains two string channels and one time channel, but the
wrong data is being deleted from the string channels.
I start with a file that contains a group like this:
I run this code expecting the first row to be deleted
Dim logGroup
Set logGroup = Data.Root.ChannelGroups("Log")
Call ChnAreaDel(logGroup.Channels("Name"),1,1)
Call ChnAreaDel(logGroup.Channels("ID"),1,1)
Call ChnAreaDel(logGroup.Channels("Timestamp"),1,1)
but end up with this:
The first row of the Timestamp channel is deleted, but the Name and ID channels get their last rows deleted.
I have played around a bit and it seems to me that for a string channel ChnAreaDel only deletes from the last row.
Is there another function I should use?
Any help would be appreciated.
Thank You,
Joe
Solved!
Go to Solution.

Hi Joe,
I've reproduced that ChnAreaDel() bug you reported in both DIAdem 2010 and 2011-- really odd. In the meantime, you can use this older approach that uses a string parameter to point to the channel collection to remove the row(s) from:
Set logGroup = Data.Root.ChannelGroups("Noise data results")
ChnStr = ""
FOR Each Channel In logGroup.Channels
ChnStr = ChnStrAdd(ChnStr, Channel.Properties("Number").Value)
NEXT
Call DataBlDel(ChnStr, 1, 1)

Intersection Shuttle

Hi,
I have implemented an intersection-shuttle with JHS following the Oracle JHeadstart 10g for ADF Release 10.1.3. It works fine, but when I try to delete a selected row, it disappears of the list but not of the database.
Any suggestions?

Am I right that you want to delete a row in the intersection table, by shuttling it from the selected list to the unselected list and clicking Save?
Enable the ADF Business Component Diagnostics (see http://download.oracle.com/docs/html/B25947_01/bcquerying005.htm#CHDBBEEB), and check which update/delete commands are sent to the database. Maybe that helps to identify what happens.
Hope this helps,

Problem with multi row delete

Hi, I'm new in apex and I tried to build master detail report on some view. Everything is cool but "delete checked" doesn't work.
"ORA-20001: Error in multi row delete operation: row= , ORA-06502: PL/SQL: numeric or value error: NULL index table key value,"
the problem is that I don't know what is wrong :), I have a special trigger "instead of delete on MY_VIEW", but in this error problem is not explained.
Anybody knows what can be wrong? It is probably a problem with trigger or multi row doesn't work with views? I couldn't find how MRD knows what kind of statement use to delete rows so I don't know if the statement that program used is correct. In debug it lokks that:
0.32: ...Do not run process "ApplyMRU", process point=AFTER_SUBMIT, condition type=REQUEST_IN_CONDITION, when button pressed=
0.32: ...Process "ApplyMRD": MULTI_ROW_DELETE (AFTER_SUBMIT) #OWNER#:MY_VIEW:ITEM1:ITEM2
0.33: Show ERROR page...
0.33: Performing rollback...
thanks for any help
//sorry for english mistakes
edit: it doesn't matter if I use in trigger delete from ... where item1=:OLD.item1 ; or if I use item1=:P4_item1 (which actually saves correct values)
Edited by: user5931224 on 2009-06-13 08:55

I realised that this is not a problem with trigger, I changed trigger to "NULL;" and problem is the same. Maybe sb used master detail on view not only on tables and know what can be wrong in this situation?

Intersection-shuttle not working

Hi,
I am using JHeadStart 10.1.3. i displayed detail records in sub tab of parent form page as intersection-shuttle.
Shuttle is displaying results correctly. But after moving some results fom left to right and clicking on Save button, i am getting "No changes to Save" message instead of saving the results.
Please any one help me on this?
Regards,
A V G K Raju

I have the same issue after following the intersection-shuttle example in the JHS developers guide.
I downloaded the hr demo application, but only found a parent-intersection example. not necessarily helpful for an intersection-shuttle.
I would like to try and restart this thread. Any one out there have ideas.
It seems as if the underlying VO does not know it has been modified. This is the case for adding rows or removing rows from the list.
Thanks,
Jim

JHeadstart Version 10.1.2.0 Intersection Shuttle Trailing won't update

I'm new to JHeadstart and think it is a great time saver, that is until you run into problems. I've been trying to figure out for quite some time now why the trailing listbox for my Intersection Shuttle won't update. I have confirmed that the database is being updated properly, the intersection table has the rows that should be displaying in the trailing listbox. The leading listbox is being updated correctly, the items I move over to the trailing listbox no longer appear in the leading listbox. But the trailing listbox always stays empty. Will someone please give me some pointers that I can use to try and figure out what's going on.
Thanks,
Rick

How to Display Number of Rows Deleted/Inserted etc... in PL/SQL

In Oracle 10g PL/SQL, I have a delete statement in a stored procedure. It is not in a cursor. I want to see the number of rows I've deleted. I can use the dbms_output.put_line package. I should know this, but I don't have time to perfect the syntax. How would I get the number of rows that get deleted and display it via dbms_output.put_lline?

No time to google either I guess.

Instead of delete trigger rows deleted

Hi All.
Im using a few instead of triggers over a view. The view selects data from other tables and merges them together. This view essentially forms the parent of a few one2one relationships with other tables.
However my application doesnt know its a view (im using hibernate orm framework) - so when I delete this object which is mapped to a view, I get an error saying that no records where deleted. Also, if i test in sqlplus, i get "0 rows deleted" in response to a delete - which of course is true, but i want it to say 1 or some number of my choice.
How can i modify my "instead of delete" trigger so that the number for records deleted count returned to caller is 1, or some number i can define?
Here is my current trigger...
create or replace
trigger product_view_delete_trigger
instead of delete
on product_view1
for each row
begin
null;
end;
Thanks.

In regards to why Im using a view - its discussed here...
Crazy Union across 3 tables
The view im using is not updatable - it uses a union. I use "instead of triggers" to trick my application into thinking its a real table which is insertable. And this works fine.
Im having trouble tricking my application into think that the delete was successful, because the "instead of delete" trigger doesnt actually delete anything - which is what i wnat - but i want it to report back to the caller that a delete occurred.
I want the SQL%ROWCOUNT to be set to 1 or whatever. Perhaps this is not hte variable, but im hoping there is some variable I can set which is used to report back to the client as to how many records were deleted.
thx.

POPUPKEY_FROM_QUERY returning value to wrong row

Hi,
I'm running Apex 3.0.1. I have a tabular report that I'm trying to add a popup from query that returns the key/code value (instead of the display value).
I can call the pop-up okay, but it's returning the value to the wrong table row. I can see in the naming of the Javascript functions that it's looking at the wrong row. For example, here are 4 rows in display order and the names of the Javascript function calls:
1. javascript:genList0_f15_1()
2. javascript:genList0_f15_3()
3. javascript:genList0_f15_2()
4. javascript:genList0_f15_0()
I can see in the function call that it's passing an index that doesn't match the displayed row number here:
"&p_element_index=" + escape ('1') + So if I click on the LOV icon for row 1 and select one of the LOV values, it will return the value to the second displayed row (zero-based index).
I've read here of some issues with not having all rows make the call (e.g. in this post from Patrick Wolf date_popup returning value to wrong row but all my rows have values.
The tabular report allows sorting by column headers, which I would guess is (at least part of) what's messing the function numbering? The query generates the rows, including the function calls, but the report displays in a different order?
Any suggestions would be greatly appreciated.
Thanks,
Stew
Good luck,
Stew
My Oracle Community blog: http://www.oraclecommunity.net/profiles/blog/list?user=stewstryker

Christina,
You hit the nail on the head! The tabular form region was defined as SQL Query - without the Updateable part! I'm not sure why I didn't have it that way from the start...
Now I just have to find and implement the Javascript that will copy the updated value that's returned by the LOV to the correct column (defined as apex_item.text). That was the only way I could figure how to allow the user to enter a value directly or select from a LOV. Clumsy but functional I believe!
Thanks to you and Scott for the tips.

Date_popup returning value to wrong row

I have looked at the thread below and still cannot get my code to work
Re: prevent certain rows in updateable report from being updated??
I have a tabular form that is used for a mass approval system for managers. In this tabular form the managers are allowed to change 2 fields...that status field which is a static lov and the approval date field. The approval date field will always be null when the user comes into the form so we have this field set automatically to the sysdate. The problem we are encountering is that when we change the date field to something other than sysdate the system will send the new date from the date picker to a different row. I found the thread above and tried to implement it in my code but it is still returning the data to the wrong row. I was trying to decipher the code and wasn't really sure about it so I thought I would put my code here in hopes that someone could help me. (NOTE - I don't really need the decode statement for the date_popup but if I didn't have it I would get an error so the first part of my decode statement shouldn't ever be hit cause we don't have an approval status of P.

mtuser,
you have to be a little bit more patient, your initial postings was just a few hours ago.
About your problem, have a look at Re: prevent certain rows in updateable report from being updated??
I think it explains your problem and offers a solution for it.

Tabular form - Multi row delete error

Apex 4.0.2
We have a simple CRUD type of application on a bunch of tables built using Apex v1.6 that has, over the years, been upgraded to v4.0.2 and it is working mostly fine. It uses all out-of-the-box standard components, forms, classic reports, nothing too fancy. Recently one of the tabular forms started to misbehave, the multi-row-delete process raises a No Data Found error. The tabular form is based on a view with a INSTEAD OF trigger to handle the DML. Manually deleting the row in SQL*Plus works fine delete from mytab here pk_id = :pk_id but selecting the same row in Apex and clicking Delete raises the error.
How does one go about troubleshooting & fixing this sort of thing? I tried re-saving the region in the Builder, exporting/importing the entire app, nothing. Running in Debug mode doesn't really provide any additional information, just that the MRD process failed. Tabular forms are the most frustrating, opaque component in Apex, wish they were easier to troubleshoot.
Any ideas?

Hello Vikas,
>> How does one go about troubleshooting & fixing this sort of thing?
By given us a bit more information :)
• Is it a manual Tabular Form (using the ITEM API) or a wizard created one?
• Are the Insert/Update operations work correctly? If not, what is the type of your PK column(s)?
• If the problem is limited to the Delete operation, maybe the problem lies with the checkbox column. Are you sure that on page it is rendered as the f01 column?
• As triggers are involved, can you save the PK that the trigger sees? Is it the expected value?
• Are there any other processes that are fired before the DML process? If so, maybe the problem is with them. You can temporarily disable them and see if it change anything.
>> Tabular forms are the most frustrating, opaque component in Apex, wish they were easier to troubleshoot
Yes, I agree. However, I believe that 4.1 made some serious advancement where Tabular Form is concerned. Having simplified Tabular Form related Validations and Process should make things easier, and as a result, prone to less errors. Still, the main problem is that the type of error you are talking about is usually the result of metadata problems and these are indeed very hard to track.

Arie.

Multi-row Delete (MRD) on a view?

All,
I created a tabular form on a view, using an instead of trigger to encapsulate the logic for the data manipulations. Works great--until someone checks a row and hits the delete button, at which point APEX throws this error:
ORA-20001: Error in multi row delete operation: row= 107970-18527, ORA-06502: PL/SQL: numeric or value error: character to number conversion error,
Error multi row operation failedAs far as I can tell, it's not even getting to the trigger; I commented out the body of the instead of delete trigger (replacing it with null), and I'm still getting the same error. I have no validations or processes on the page at this point.
The underlying data of the view requires three columns for a unique identifier, so I've concatenated two of them together as an extra column in the view (creating a varchar2 column), and told the MRD to use the calculated column and the third column as the primary key columns. But even using two of the three numeric columns (tweaking the trigger to use a hard-coded value for the third) as an ID fails miserably.
Any idea what's going on?
Thanks,
-David

Validation in a Multi Row Delete

Hi all,
i made a page with an updateable report region - all works fine.
But now i want to do a validation in the process 'Multi Row Delete'.
The aim is to guarantee that the specific row is not deleted if the validation for that row fails.
How can i achieve that?
Any feedback is welcome.
Best regards
Martin

Hi,
many thanks for your reply.
Yes in my case it is a tabular form and the validation should be done vor 'multi row delete'. Accordingly to the article you mentioned i created a validation with the following PL/SQL code:
DECLARE
vRow PLS_INTEGER;
BEGIN
FOR i in 1..apex_application.g_f01.COUNT LOOP
IF apex_application.g_f01(i) IS NOT NULL THEN
vRow := TO_NUMBER(apex_application.g_f01(i));
IF lpkom_api.checkPersonAssigned(apex_application.g_f03(vRow)) THEN
RETURN 'Delete is not allowed for this row.';
END IF;
END IF;
END LOOP;
END;
Best regards
Martin

ORA-20001: Error in multi row delete operation: ORA-01403: no data

Whenever I attempt a multi-row delete on my master detail page, I recieve the error:
ORA-20001: Error in multi row delete operation: ORA-01403: no dataI have seen in other threads that the primary key attribute of the underlying table needs to be set to 'Show' in the report attributes. I have tried this both with it displaying as 'Hidden' ('Show' is unchecked) and with it displaying as text. Either way still gives me the same error.
Is there anything else not mentioned in the other threads that could be causing this error for me?
Thanks.
BoilerUP

Jimmy,
In your multi row delete process you specify schema name, table and column name. Your report needs to be of type âSQL query (Updateable report)â. And your report needs to include the primary key column of your table. The column or alias name of that report column needs to correspond with the actual column name of your table.
