MRU process on Tabular Form

Hi,
I have a table based form wich has has his Automated Fetch/Automatic updates processes.There is a page item P1_ID wich I set up to be returned from AutomaticRowProc with 'Return Key Into Item' P1_ID.When I create a row I see in debug that P1_ID has the proper value (returned by a 'before insert' trigger).
On the same page I have also a Tabular Form wich has a column COLID wich has the 'defaul value' = P1_ID .
AutomaticRowProc has sequence=10 , ApplyMRU has sequence = 20 . Both processes fires on Request=CREATE.
How to make that ApplyMRU proces to set the value of COLID = P1_ID ?
Thankyou.

Hi David,
If it's going to be anywhere, I would have thought it would be on the APEX_APPLICATION_PAGE_RPT_COLS view. Assuming that Apex outputs in the DISPLAY_SEQUENCE order, and ignoring items that won't involve an fnn item on the page (eg, those with WITHOUT_MODIFICATION in the DISPLAY_AS_CODE column), that should result in the values you need.
However, and there's always an "however", I've had instances in the past where the order of the columns in the report definition does not match the order of the fnn values. Usually, either because the page has been copied or because I've done things with the columns after the initial creation (more them about or added new ones, for example). I have to say, though, that this was on older versions on Apex and I haven't really double-check things on Apex 4 (except that I've noticed that copying tabular forms doesn't work properly!).

Custom process on tabular form

Hi everyone,
I was wondering if anyone could show me an example of a process on a tabular form that checks the rows and values of other columns
does the insert with the MRU process and immediately follows with the custom process in order to update another column of the same table (used in the tabular form).
I would really appreciate the help.
Kind Regards,
Cleo

Hi Cleopatra,
I think that you will need to manage all the required steps in the "Custome Process".
You can go throug every line of the report adapting the following example:
FOR I in 1..APEX_APPLICATION.G_F01.COUNT LOOP
DELETE FROM emp WHERE empno = to_number(APEX_APPLICATION.G_F01(i));
END LOOP;
You can see more details in: [http://docs.oracle.com/cd/E37097_01/doc/doc.42/e35127/apex_item.htm#CHDDCHAF]
By doing this you will be able implement as many processes you need for each line.
Hope you find this info help full. Try it and let me know if it works!
Kind regards!

MRU Error in Tabular Form

Hi
I created a tabular form. Also created a trigger that would insert a sequence number, user and system date each time a new record is inserted. I have associated an existing LOV to one of the fields.
I hit the 'Add Row' button. Select a value from the LOV for the account code. Hit the submit button and page indicates 1 row inserted.
I hit the 'Add Row' button again to insert another row and the following message appears:
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 = "F246ADAF68494BEE51356ECC92B1047C", item checksum = "B9E444CAB12B67D92A5DBC8BB3E48517"., update "TEST"."VIEW_ACCOUNTS" set "CONTROL_SEQUENCE" = :b1, "ACCOUNT_CODE" = :b2
If I come completely out of the application and go back in to insert another record, I get the same error.

Hi,
I think above probem is caused by the trigger created.
Check without the trigger for test-purposes and check if the error is gone. ( checksum error, I suppose )
Kind regards,
Iloon

Checkbox in tabular form - help needed

I'm trying to build a tabular form, with a checkbox for a field that can have value 'Y' or 'N'. Adding the checkbox is no problem, with the htmldb_item.checkbox API.
However, processing it is.
On this forum I found a way to process the checkboxes, by looping through all the records (with the help of htmldb_item.hidden in which the id is stored) and reading the value from the checkboxes and updating the column if the checkbox is checked. (see Re: Report with updateable checkbox)
however, as soon as I add a htmldb_item.hidden item, I receive the following error when I submit the tabular form to the Multi Row Update process:
"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. "
My query:
Select id
,htmldb_item.hidden(1,id)
,htmldb_item.checkbox(2,id, decode(field, 'Y', 'CHECKED', NULL))
from table
What am I doing wrong?
is there a better way to process a tabular form with checkboxes?
Or should I process all the rows manually by updating every record even if it hasn't changed (with a loop through all the records)?

Tonnie, did you ever get an answer to this question?

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

Update process does not work on Tabular Form

First form is created using wizard, and therefore works perfectly.
The update process is as follows:

Please advise, what is causing a problem with update?

Sloger,
if this is your tabular form
SELECT apex_item.checkbox (30,
...and this is your update statement
FOR i IN 1..APEX_APPLICATION.G_f*30*.COUNT
...Then you will only ever update records that have been checked. Unchecked checkboxes are not passed back in the global array. You need to have a hidden column with the ID's for the record and loop through that when you are updating/inserting. That is why the built in tabular form has a MRU and a MRD. the MRU loops through the hidden ID column. The MRD loops through the checkbox.

Page process throwing No data found error when deleting tabular form item

Hi guys,
I am trying to run a page process just before the Tabular form's MRU process and it's throwing a no data found error. Here is my code:
BEGIN
     for i in 1..apex_application.g_f02.count LOOP
          IF apex_application.g_f01(i) is not null THEN
               UPDATE STOCK
                    SET PRODUCT_QUANTITY = PRODUCT_QUANTITY+apex_application.g_f08(i)
               WHERE site_id = :P21_SITE_ID and product_id = apex_application.g_f02(i);
               COMMIT;
          END IF;
     END LOOP;
END;Here f01 is the checkbox column and the if-statement is causing the problem because if I get rid of the update statement (leaving just the commit) then it still throws the error.
When I click on a checkbox and hit delete button which fires off both this process and then MRU I get the no data found error.
Would be grateful if someone could shed some light on this. Many thanks.

You are iterating on the f02 and checking for f01 not null. That is wrong usage of the the checkbox item. Please see these links . especially the OnSubmit Process examples.

Cannot Update Tabular form Values Error in mru internal routine: ORA-20001:

i have created some master detail records through a manual tabular form. Iam getting the following error when i tried to updated the values through another inbuilt tabular form....
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 = "9067F4C5EF14529F831CB42B5567C288", item checksum = "07865E78639EB6477FB5DFB8B02EA047".,

Hi
Hopefully my response to your Error in mru internal routine: ORA-20001: no data found in tabular form thread will help. In this thread's example, there is no error message that displays the column names required, but the principle would be the same: Make sure that all fields drawn from the table are included as editable or hidden columns on the report (so that there is one instance of each field shown with a tick in the Edit column on the report's Report Attributes page).

Simple question about tabular forms: error in MRU

hi to all,
i write here to check if what i think about tabular forms is confirmed.
If i build a master- detail or tabular form and the underlying table are modified, the page where the tabulare form is contained doesn't work anymore.
if what i've written above is correct, is there a way to realign the fields of the tabular forms to the db fields and make my page work again without rebuilding all?
Can i modify something, somewhere inside apex to make my page run again?
The error i get (in italian / english)
Error in mru internal routine: ORA-20001: Errore in MRU: riga= 0, ORA-20001: ORA-20001: La versione corrente dei dati nel database è cambiata da quando l'utente ha iniziato il processo di aggiornamento. checksum corrente = "ED73B05FA6016F8D5F3B4B5B69AF482D", checksum elementi = "CFD72DCC4221A340057D654B54EA7A04"., update "NEWPROJ"."CNT_VAL_SEG_DEMO" set "ID" = :b1, "FK_CNT" = :b2
Means: The version of data in db (fields of the tables?) has changed since the user started the update process.
By the way this sentence under my opinion can trick you as
in italian 'La versione corrente dei dati nel database'
can means both that data contained in tables have changed (dml error / process error / data the user see not are the real underlying data). Can mean as well the field definition is changed, however a more meaningful message in italian is: ' la definizione delle tabelle usate dall'oggetto tabular form é cambiata'.
That translated in english is ' DDL of table/s used by tabular form has changed'.
thanx a lot

HI Heinz,
yes is now clear, however is a pity that a litte change in the query has a lot of
implications: a change in the structure of DB means new feature / the data model is not alligned with current requirement. So usually (but not always) it means changing the SELECT as well.
Such Apex is a Rad an impression is that if you build a complex forms with several linked reports / field and one day you have to change the query of the TABULAR FORM / MASTER DETAIL generated with report you get a lot of rebuilding.
I think i will avoid the use of this 2 object in the future and use more htmldb.items in the select.
bye bye

Tabular Form Unable to update : MRU error

Hi,
In debug mode, I got that message when I try to update the only row I have in that form :
0.08: Processing point: AFTER_SUBMIT

0.09: Show ERROR page...
0.09: Performing rollback...
Error in mru internal routine: ORA-20001: no data found in tabular form
What can I do ?
Thank you.

The tabular form wizard creates a display report column for your primary key column in addition to the actual hidden column that stores the PK for MRU processing. To differentiate the display column from the hidden column, it gets a different alias by appending a suffix to the primary key column's name. That suffix plus the PK column name can't exceed 30 characters, and the suffix is 8 characters long, so this leaves 22 characters for the PK column name. Clearly this implementation has some room for improvement, and I expect that we'll address this in a future version of APEX.

Marc

Tabular Form MRU Update

Hi All,
I have a table Tab1 with columns EditDate DATE, ID Number, Value Number.
It has composite primary key (EditDate, ID).
Sample values are stored as follows.
Edit Date ID Value
01-MAY-2007 01:00:00 1 0
01-MAY-2007 02:00:00 1 0
01-MAY-2007 03:00:00 1 0
01-MAY-2007 04:00:00 1 0
I created a Tabular Form with Update Only. Everything is default created by APEX wizard. When I update value field and click Submit I get the following error message. Also, Why my primary key is showing in the update statement? I thought it should be a part of where condition.
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 = "8395BC1EF2E94441B2921CD18505810C", item checksum = "F6C92BBA1B8ACD35D0BCCF59FC4B9785"., update "Tab1" set "EditDate" = :b1, "ID" = :b2, "Value" = :b3
Any help is greatly appreciated.
Thanks

Also, How can I make sure that correct hour ending is updated?
Any example is greatly appreciated..

Manual tabular form "Update Process"

Hello,
i made a tabular form manually,
now i want to add an update process, but its not working?
I created a Button "P_UPDATE" and i added a Process which listens to the P_UPDATE Button.
i used the following PL/SQL script:
for i in 1..htmldb_application.g_f01.count
loop
update MATCHUMSATZ
set PARTNER_ID = replace(htmldb_application.g_f10(i),'%'||'null%',NULL),
RECH_DATUM = replace(htmldb_application.g_f02(i),'%'||'null%',null),
RECH_NR= htmldb_application.g_f06(i),
PROV_GRUNDLAGE= htmldb_application.g_f08(i),
KUNDE= htmldb_application.g_f14(i),
VERTRIEBSART_ID = replace(htmldb_application.g_f17(i),'%'||'null%',NULL)
where id = htmldb_application.g_f01(i);
end loop;
This is an example which i customized from: http://www.oracle.com/technology/products/database/application_express/howtos/tabular_form.html
I suppose that 'htmldb_application.g_f01' is the ID of the table 'MATCHUMSATZ'.
Why is there replace() and sometimes not ?
Would be glad if anybody could help me!
Phil

Hi Phil,
You can add in the in-built MRU update process that will do this for you. When you add a process, select Data Manipulation then Multi Row Update, then follow the prompts to link it to your table.
In your code snippet, htmldb_application.g_f01 refers to the first column in your form (even if this is hidden). Normally this is the Primary Key for the table on which the form is based. htmldb_application.g_f02 refers to the second column and so on, although you can assign any number from 1 to 50 to each field when you create the sql statement.
The replace() function is used because some of the fields will contain %null% which needs to be converted to null before updating the table.
Regards
Andy

Processing mutliple records on multiple pages in a tabular form

I'm a newbie to Apex (4.0). I have a tabular form displaying 500 rows records in multiple pages. The row selector is selected by defaulted ie. all rows have been checked. Upon unselecting items in multiple page, the Multi Row Delete (Post Processing Request) only deletes the records selected on the page. It seems like the ROW SELECTOR does not keep track of the checkboxes on other pages. Any thoughts on how to solve this would be helpful.
Thank you.
Ed.

Sybrand,
Thanks for the response. So in that case, how would I approach the following requirement:
Tabular form that displays 500 records each in multiple pages. The Row Selector column is selected by default. The user will uncheck certain rows in certain pages. I would like to perform a Multi Row Delete for alll the records that were selected.
Thanks,
Ed.

Hi User XY,
tabular forms do not have Page Items. The values you entered in the tabular form are stored in arrays like APEX_APPLICATION.g_f01 to g_f50.
Here are some links you might find helpful: http://www.talkapex.com/2008/07/manually-creating-tabular-form.html
