Using multiple LOV popups in a multi-row updatable report but save to 1 col

Hi,
I'm trying to generate a multirow updatable report, which has only 1 writeable column. There is a read-only column that indicates the type of value that the writeable column should contain (it's a varchar2). The second column will be a LOV popup.
I can create the report by setting the 2nd column to a LOV and it's fine, however I really want the LOV to be different, depending upon the value of the first column for the row.
For example, if the first column is "list" then I want the popup to show all my "lists"
If the first column is "role" then I want to the popup to show all my "roles".
There will be a mixture of values within the entire rowset.
I've so far managed to use a case statement to generate different LOV popups, which are displayed as required but the returned data isn't written back to the correct field.
If I use the same p_idx value then there is only one javascript function created and it always stores the data in the first rows column.
If I use unique p_idx values, then it works better but selecting a value for the 2nd row will store it there but also overwrite the 1st rows value as well.
My SQL for the report currently looks like this (cut down for clarity)
SELECT RULACTPRMIDD, /* PK */
CASE PRMNME /* type */
WHEN 'list' THEN
APEX_ITEM.POPUPKEY_FROM_QUERY(2,rulactprmval,
'SELECT LSTNME r, LSTNME d FROM LSTLST', 0)
WHEN 'role' THEN
APEX_ITEM.POPUPKEY_FROM_QUERY(2,rulactprmval,
'SELECT ROLNME r, ROLNME d FROM PDRROL', 0)
END dynamic_popup
FROM CPNRULACTPRM
I can't think of an example where i've seen this done within the Apex development environment otherwise I would refer you to that.
An alternative option would be to pass the type of value required to the same LOV and then get the LOV query to only show the appropriate values - i'll look into this as a workaround option.
thanks

User478832,
I didn't look thru all the code but I have a feeling your problem is the 9th line in the On Demand process. (the 9th line in this post anyway)...
htp.prn('<option value="' || rec.cpc_name|| '">' || rec.cpc_name|| '</option>');
You modified your query to get a different column but your returning the same column later: rec.cpc_name x2
I assume you want to display NAME and return ID so change it like this...
htp.prn('<option value="' || rec.cpc_id || '">' || rec.cpc_name|| '</option>');
Let me know if that helps...

Conditional Select List in a Report maintained using a Multi Row Update

I have a SQL Report that is maintained with a "Multi Row Update" process. One of the columns needs to be ether a "Select List" based on a named LOV or just "Text" (Read Only) based on the value in the column. I have the UI working using a case statement and apex_items in me SQL but the Report Column is not marked "Edit" and the "Multi Row Update" process just ignores changes.
Any help would be great!

Just curious, why is the first parameter to in third TEXT_FROM_ITEM invocation NULL instead of 20? Also check your first parameter in your ELSE. Shouldn't it be a global number as well?
Did you try adding a hidden item to your SELECT statement? Something like:
(case
when CSSN.KTTR_BILL_STAT_UID = KT_UTIL_PKG.get_kttr_uid_from_ref_val('SESSION_BILL_STAT','SESSION_BILL_STAT_1') then
apex_item.select_list_from_lov(20,CSSN.KTTR_BILL_STAT_UID,'KTTR_SESSION_BILL_STAT_PRPR','','NO')
when CSSN.KTTR_BILL_STAT_UID = KT_UTIL_PKG.get_kttr_uid_from_ref_val('SESSION_BILL_STAT','SESSION_BILL_STAT_2') then
apex_item.select_list_from_lov(20,CSSN.KTTR_BILL_STAT_UID,'KTTR_SESSION_BILL_STAT_PRPR','','NO')
when CSSN.KTTR_BILL_STAT_UID is null then
apex_item.text_from_lov(20,'KTTR_SESSION_BILL_STAT')
else
apex_item.text_from_lov(20,CSSN.KTTR_BILL_STAT_UID,'KTTR_SESSION_BILL_STAT')
end) as KTTR_BILL_STAT_DISP,
apex_item.hidden(30,CSSN.KTTR_BILL_STAT_UID) MIRRORThen in either an Javascript onBlur event on KTTR_BILL_STAT_DISP or in a Page Process assign the value of KTTR_BILL_STAT_DISP to MIRROR.

Multiple Users - Tabular Forms - Multi Row Update.....

Greetings All,
Any comments, assistance, links, or even answers on the following situation would be much appreciated....
I have a Application Express 4.0 (Could upgrade to 4.1 if it would help this issue)
I have a wizard generated tabular form on a table, the form will show up to 600 records (rows) on a page.
Part 1:
The situation:
User 1: Opens the form and brings up latest data set.
User 2: Opens the form and brings up the latest data set.
User 1: Changes data for record 1
User 1: Hits submit. The data is saved.
User 2: Changes data for record 1
User 2: Changes data for record 2
User 2: Hits submit. The following error is produced:
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum = "3EE15D666E9DBDC59D34CE4CFB3950C0", item checksum = "922DA12AE1E3D8856695745C4D2830D2"., update "<Removed> Error Unable to process update.
When this error occurs no updates get made to the table.
I understand that row 1 can not be updated, however I would like row 2 (and all other rows where there is no conflict) to be updated. I would then like to be able to highlight in the form the rows that failed to update (And reload the data in them from the DB).
Is this something I can achieve using my own MRU procedure, or in another way?
Can anyone point me to a good example, tutorial or book showing how to do this.
Thanks!

Thanks for the comments guys.
I have solved my issue in two different ways. Way one was not so clever, but worked, involving writing my own process for handling multi-row updates and would allow a user to fill in data for multiple rows (say 10) and have only the row with changed data rejected. V2 takes a very different approach, it uses Javascript, AJAX and the DOM model of the form to check when data is changed / updated by the user. Essentially, when a user enters an updateable form element, a AJAX request checks if the data has been changed. If it has, the value in the form is updated, and the color changed to blue to alert the user. When the user updates the data item, and AJAX request posts the new value to the database, where it is inserted. I had to build a bit of a framework to make this useable, and have to use dynamic sql in the database packages, but it work really well for what my users need! There are limitations (Currently it only supports date fields, text fields and drop down lists) but it works for me. It also involves traffic back and forth with the server each time a user moves the focus to a new form element, but it is a very light request and the work to do the select / updates in oracle is all based on a primary ke, so is ver quick.
Solution 1: (Would need to be made much more elegant):
1: Create a new text Item called P5_MESSAGE (To display error / success messages)
2: Create a new process:
DECLARE
l_cks wwv_flow_global.vc_arr2;
j pls_integer := 1;
vUpdatedCount number := 0;
vErrorCount number:=0;
vMessage varchar2(4000):='';
BEGIN
select wwv_flow_item.md5(firstname,lastname,age) cks
BULK COLLECT INTO
l_cks
from VA_TEST1 ;
for i in 1..l_cks.count
loop
if htmldb_application.g_fcs(i) != l_cks(i) then
-- Log error
vErrorCount:=vErrorCount+1;
vMessage:=vMessage||'Could not update row with ID:' || htmldb_application.g_f01(i) || '. This data has been updated by another user since you retrieved the data.<br>';
else
-- Do insert
vUpdatedCount:=vUpdatedCount+1;
update VA_TEST1
set
FIRSTNAME = replace(htmldb_application.g_f02(i),'%'||'null%',NULL)
,LASTNAME = replace(htmldb_application.g_f03(i),'%'||'null%',NULL)
,AGE = replace(htmldb_application.g_f04(i),'%'||'null%',NULL)
where ID = htmldb_application.g_f01(i);
end if;
end loop;
:P5_MESSAGE := vMessage;
end;
Note, this currently updates every row, even if the data is unchanged, this could be fixed by comparing the checksum of the data to be inserted with the checksum of the data in the table, if the same then no need to insert.
Solution 2:
Too complex to explain in detail here, if you need to implement this then let me know.

Multi Row update using pl/sql anonymous block process

Does anyone have an example of multi row update using a pl/sql anonymous block process?
The reason I can not use the apex mru process is that the table in questions has a five field key.
My attempts have failed with a bad number.
Thanks,
Gary

Hi Gary,
can y<ou pls send the definition of thet table and the UPDATE sql.
It is a littel difficult like this.
We need more info.

Multi row update not occuring

I have created a tabular form using the wizard. This form will show three columns (and in addition a checkbox). I would like this form to be updateable in only certain instances. Because of that, I select the columns twice. I make one of them updateable, and the other read-only. Then I have a conditional display for the columns, so that the updateable columns are shown if a status variable in my page is 'EDIT' and the read-only columns are shown otherwise.
The problem is that the multi row update does not occur. If I show one of the read-only columns when in the edit mode, the update is done. Also it is executed if I show one of the editable fields when the page is not in edit mode. But when I show only the editable fields in edit mode, and only the read-only fields when in read-only mode, the process is not run.
What can I do about this? Why doesn't the multi row update occur?

An alternative is to control the updates by controlling the buttons. Only show the submit/update button if the status on the page is "EDIT".

Multi-Row Update form with wrapped fields

Hi,
I have a multi-row update form with too many fields to fit on the screen without having to scroll. Is it possible to wrap the extra fields onto a 2nd line.
So each DB record will actually span 2 srceen rows and fit nicely into my browser ??
Thanks for any help,
Brandon

It is possible, but would require some serious work on the report template, to create a custom row template.
I started to do this at http://htmldb.oracle.com/pls/otn/f?p=24317:191 but realized that it is hard work. Also, where would you show the headings for the second part of the row (split onto the next line)?
Instead, I would use the Show/Hide columns technique (client-side scripting) to reduce the number of columns shown. Search for it on this forum. Carl and I have some good examples out there.

hi oolite
i can't help you with your problem
but i have one suggestion
i don't know whether you created your tabular form with the wizard or manually
when you use the wizard
i would suggest that you try to build a tabular form manully
in fact it is a little bit more work but i think all what you have done by yourself
is more transparent and errors should be found easier
other suggestions take a look
Error in mru internal routine: Error in MRU
Error in mru internal routine
or search for error on mru
sorry that i can't tell you more

About Multi Row Update...

APEX support Multi Row Update, but it is only support have two or fewer columns making up the primary key. now i want to use 3 columns as primary key to update datas, i how to implement it in APEX? thanks
· Table Owner: The schema name for the owner of the table.
· Table Name: Enter the table name or view. MRD’s and MRU’s can only dynamically build SQL statements for a single table or view.
· Primary Key Column: This is the first column of the primary key for the table. It is used for building the WHERE clause for the dynamic statement.
· Second Key Column: This is the column name for the second database column making up the primary key for the table. The MRU and MRD processes can only be used for tables that have two or fewer columns making up the primary key.

More than one multi row update region on one page - how ?

Hi.
I have a page on which i want to use two multi row update regions ( updateable report with three buttons like new/delete/save ).
But i do not find a setting for the MRU-Process oder "Add-New-Line" Process that lets me reference this process to a specific region.
The problemm is, that after adding the second region to the page, the "Add-New-Line" - process only adds the new line to the second region and not to the first region anymore.
How can i make two processes where one adds a line to region1 and the second adds to region2. Same question is with updates too. How can i say that process on updates the changes in region1 and the other process updates the changes in region2 ?
Thanks for help.
greetings
bernd

Unfortunately, the builtin MRU process supports only 1 updatable region per page.

Multi Row Update for Tabular Form

1) I'm trying to understand how the built-in MRU works for tabular forms: While running through every row, does it check for changes before issuing an UPDATE or does it blindly UPDATE every row in the current pagination range?
2) If I need to write my own Multi Row Update process for tabular forms, could someone give me some tips on how to do that?
Thanks,
Pavel

1) It stored a checksum for each row that it renders. It calculates the checksum again before processing the rows. The UPDATE statement it issues has a predicate like where old_checksum!=new_checksumSo, it only updates the rows that have at least 1 column value that is different (causing the row checksum to be different)
2) See the howto at http://www.oracle.com/technology/products/database/application_express/howtos/tabular_form.html

Enable/disable lov button in a multi-row bloc

Hi all,
I have a form in which there is a multi-row block with some lov buttons related to some items,
in query mode, user should not be able to modify item, item property update_allowed is set to false, that worked, but user is able to modify item when he clicks on the lov button...so i want to disable the button for query records and for record in (insert or new), button should be enable,
i tried some tips but don't work, do you have any idea
Thanks for your help.

Hi,
Can you suggest some methods to enable/disable LOVs in my search query? I have a customized VC which performs search and I need to enable/disable the LOVs depending on requirement.

LOV button navigation in multi row block

We have two fields in a multirow block, Role Type and Parent Role Type(which is a LOV button). When the current row selector is on a Role Type row all Parent Role Type LOV buttons for all the rows change only the current selected row. With Designer we set Keyboard/Mouse navigable properties to Yes(in the OLB) which fixed it but with Headstart these properties do not fix this problem. Any info and suggestions would be appreciated. Thanks.

Ok, now I understand.
Unfortunately, you have run into some standard forms behavior that doesn't work the way you want it to. The LOV button is not navigable, because your cursor needs to be sitting in the data item when the call to the LOV is made. Since this button is not navigable, the cursor will not move to the current record when you press the button. (Actually, the button is identical on each record.)
Possible solutions:
1 - use only 1 button in an overflow below. (Create your own action item instead of using the LOV button preference.)
2 - don't use a button at all. (Headstart provides the LOV toolbar button.
3 - Try generating the lov as a poplist. (See Oracle Designer online help).
4 - Use the new Oracle Look and Feel (available only on the web) to create a button in the field ('...').

Lauri

Need to perform multi-row update/delete

Gday,
I have a request to have one update button for a multi-row form. Also needed will be a checkbox as part of the row.
The check boxes only purpose is to signify the record should be deleted. Thus I am assuming I cannot use default
apex functionality and must manually build the multi-row form. I guess I would loop through and check to see if a
record is checked delete otherwise loop through and update all columns for that record? I am assuming I should
use the examples in http://www.oracle.com/technology/products/database/application_express/howtos/tabular_form.html
is that all still valid for apex 3.2.1?
Cheers

Hello:
You could also do the following
Generate the tabular form page using the wizard
Delete or not display the 'Delete' button
Delete or not execute the 'ApplyMRD' process
Create a new page process with a sequence higher than the standard MRU processes. Make this process conditional on the 'Submit' button. Use code similar to the one below for this page processfor i in 1..apex_application.g_f01.count loop --- f01 is the selector checbox, f02 is the hidden column with the table's PK
delete from emp where empno=apex_application.g_f02(apex_application.g_f01(i));
end loop;Now, when you click 'Submit' records with their selector checkbox checked will be deleted by the newly added page process. The rest of the functionality of the tabular form remains the same.
