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..

Refresh page but SAVE USER INPUT in tabular form WITHOUT UPDATE

Hi,
When there is a tabular form in the page and user refreshes it (in anyway) tabular form's elements are always computed with values from the table in db. Can we somehow save user input in fields so that after refreshing page user will see what he/she has typed but not submitted to db?
Regards,
Tom

Hello Andy,
Let me introduce you to the problem.
There is a tabular form based on a source table. User modifies the data and after he/she clicks Submit button the validation procedure is being run before MRU. If the result of validation is positive then MRU is run otherwise data should not be submitted to db and user should be informed about the result. Moreover, he/she should see the invalid data in fields. Not the correct one from db.
Is there any way to save a session state of these fields or of a whole tabular form? I cannot save the data in other table in db.
User cannot click 'Add row' several times in my app because after he clicks it once then the button disappears and appears again only when he/she clicks 'Submit' first (so after validation procedure).
Maybe there is some way to store fields' values in memory and then compute the form when page is loading again?
Imagine the situation that there are 100 rows in tabular form and user modifies it for one hour, clicks Submit, validation result is negative and his/her whole one hour work is lost, because the form has been refreshed according to what is stored in db. Such situation should never occur.
Regards,
Tom

Tabular Forms, MRU's & master / detail FK's

APEXV4
I've used a wizard to create a simple master detail form. Updates & delete's work fine on the detail block. When using the add row button all seems OK too. Issues arise when saving a new detail record. The PK from the master table does not seem to be populating the detail tables FK. This results in a error declaring that the FK cannot be null... as below
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-01400: cannot insert NULL into ...
Am I missing a trick here?

I have just started to look at APEX. Do you have an example of a master detail. I tried to create a form in the samples but do not get what I would expect.
Should I get a 2 block orientation or will I get something else?
Do any of the packaged apps / sample code have a good example?
Thanks!

Tabular Form Not Updating

I have an existing tabular form that has been working fine. I created a new column for and "edit" button to allow a user to edit an entry that is listed in a tabular form row. I did this so I could validate a delete action after I read that validate from a tabular form is not too reliable. I noticed after I created the edit button (which is a link to another page) that the "ApplyMRU" process isn't working. I press the "Add Row" button which gives me a new row to work with. I then press the "Submit" button. The page is submitted but when it is rendered the tabular form region is empty. I query the table but the row that I tried to insert is not there. When I created the "Edit" button (link) as a new column in the tabular for could I have broken something in the tabular form process(es)?

You are saying that you created a new colum as well. What kind of display does this Tabular Form Element has? What content are Reference Table Owner, Reference Table Name and Reference Column Name showing?

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

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.

Update primary key with a tabular form based on a select list for each row

Hello!
I've two tables: Table1 with only one column (primary key) is a foreign key for table2.column1 (primary key). There is also a second primary key column in table2.
Now I want to change the primary key values in table2.column1 with a tabular form (MRU) based on a select list (LOV based on table1.column1) for each row.
The user should be able to choose for every row a new value from the select list to change the old primary key value at this position.
How can I do this with ApEx?
I've the tabular form and so on, but at the moment I get the following error:
"Error in mru internal routine: ORA-20001: Fehler in MRU: row= 1, ORA-20001: ORA-20001: Die aktuelle Version der Daten in der Datenbank wurde geändert, seit der Benutzer einen Update-Prozess eingeleitet hat. ..."

Tabular Form update,delete

Hi,
I am using database 11G, on windows XP with apex 3.0. I have created a tabular form with update & delete buttons. The table is a detail table having foreign key columns. On creation of form I choose foreign key column as primary key. The problem is when i check one row for delete the rows having same id on foreign key column are also deleted. Second When I update the following error is reported & no column is updated,
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 = "197D508D2444826DA98FC1E3D259EA31", item checksum = "F98E67DE7FF4EC9710E5A1B052E38C78"., update "HT"."INTRA_ORAL_EXAM" set "OPD#" = :b1, "TOOTH#" = :b2, "RESTORATION" = :b3, "DENETAL_DECAY" = :b4, "XRAY" = :b5, "SYMTOM" = :b6

Hi,
OK - that makes it a bit more complicated as you can not add a primary key to a table that contains data. This means that we will have to copy the data into a temporary table first.
Assume that you have a table called C_TABLE that is defined as:
CREATE TABLE C_TABLE
FIELD1 NUMBER,
FIELD2 NUMBER
)These are the steps that you need to do (each of these bits of code run be run separately):
Firstly, copy the data into a new table:
CREATE TABLE C_TABLE_COPY
AS
SELECT FIELD1, FIELD2
FROM C_TABLECheck that the table has been created:
SELECT * FROM C_TABLE_COPYThen drop the existing table:
DROP TABLE C_TABLECreate C_TABLE with a new Primary Key column:
CREATE TABLE C_TABLE
C_ID NUMBER,
FIELD1 NUMBER,
FIELD2 NUMBER,
CONSTRAINT "C_TABLE_PK" PRIMARY KEY (C_ID)
)Create a new SEQUENCE object to provide the primary key with values:
CREATE SEQUENCE "C_ID_SEQ" MINVALUE 1 MAXVALUE 99999999999999999999999 INCREMENT BY 1 START WITH 1 NOCACHE NOORDER NOCYCLECreate a new TRIGGER object to populate the primary keys with new SEQUENCE numbers when new records are added to C_TABLE:
CREATE OR REPLACE TRIGGER "C_TABLE_BI"
BEFORE
INSERT ON C_TABLE
FOR EACH ROW
DECLARE
v_id NUMBER;
BEGIN
BEGIN
    IF :NEW.C_ID IS NULL THEN
      SELECT C_ID_SEQ.nextval INTO v_id FROM dual;
      :NEW.C_ID := v_id;
    END IF;
END;
END;Enable the trigger:
ALTER TRIGGER "C_TABLE_BI" ENABLECopy the data back into the table:
INSERT INTO C_TABLE (FIELD1, FIELD2)
SELECT FIELD1, FIELD2
FROM C_TABLE_COPYCheck the new table has primary keys:
SELECT * FROM C_TABLEAndy

How to Multi Row Update function in Manual Tabular Form

Hi All,
In my application I am using manual tabular form, for Update and insert i have written pl/sql process,
but i want to make use of MULTI_ROW_UPDATE function for update and insert operations.
How can I implement default tabular form behaviour in manual tabular form.
I am using:
Oracle Database 11g
ApEx Version 4.0
please help me, it's urgent.
thanks
MR

Hi Joao,
First Can u pl let us know your view is based on how many
tables?
If it is a simple view ,you can open the form in update mode
passing a parameter to it thru a procedure or thru a url or what
ever you feel like(form to form,etc)..I will give you an example
on how to open the form in update mode like below..
1.develop a form based on a simple view
2.Call that form Thru a simple URL
3.In the above you are opening a form with module id
ex:1234567890 in update mode and change portal30 to suit
accordingly..
4.You are passing a parameter called "ABCDEF" TO "NAME" Field to
that form for querrying..
5.Now the form will be opened in update mode and all the fields
are pertaining to the parameter "ABCDEF" and you can update the
fields....
II..Now regarding the check boxes i need to know which version
of the portal are u using..As for as my knowledge goes (up to
3.0.6) there are lot of bugs with the check boxes and check box
checked value is always "yes"(if u want to insert in to the data
base).So try not to depend on checkboxes and instead Combo is
the right answer till oracle portal is free of bugs.
No triggers are required for your requirement....
Hope i have answered your problem ...If any please revert back
with full details
Thanks

Apex_Item.radiogroup in a Tabular Form (Update Only, no Insert)

Hi,
I'd like to use a radiogroup on a tabular Form. The Form will modify only existing records.
I've seen some more elaborate examples for Tab Forms that allow Insert.
But I am trying to use the APEX_Item.radiogroup function for an example like:
"Select Chairperson_Name, Approve_Status FROM Chairperson_Approval"
The Approve_Status column can be 'A' for Accept, or 'R' for Reject, and is the only updateable column in the Tabular Form.
So I should be able to create a Tabular Form (for Update Only) on the table Chairperson_Approval with the wizard.
Then I want to be able to go into the Source and change the SELECT statement to something like:
"Select Chairperson_Name, APEX_Item.radiogroup(1,approve_status,.....) FROM Chairperson_Approval"
and then let the automatic APEX processing (generated by the wizard) do the rest. Right? Can
anybody give me an exact example for APEX_Item.radiogroup. My documentation is not clear enough on this function.
Thank you very much, in advance.
Carol

Hi Andy,
Why do you get & set TEST attribute of the radiobutton?
What is a TEST attribute?
getAttribute("TEST") == 'Y')
setAttribute("TEST","Y");So I was thinking I should incorporate this toggle me function with my radiobutton and have the following inside the toggleMe function.
$x(''P24_SECONDARY_TASK'').value=' || ad.task_id || '"')
{code}
Am I right?
Cheers

Tabular form - how to set a field to a constant?

I'm using a tabular form to update a table - and this works. Then I remembered that I need to also update the field that keeps track of who made the change.
Setting this field via the SELECT (e.g. Select 'userX' as editor from ...) for the tabular form fails due to a db concurrency error (MRU 20001) upon submission.
Attempting to override the current value in [Column Attributes] of the field in the [Elements Attibute] setting - [value="userX"] simply adds this as the second value argument of the input element (of the html source).
Suggestions?

Similiar scenario - I have a flag in this table set false that a user can set true when they feel they have satisfactorily reviewed the record.
Since it's in a tabular form it can be changed along w/ other records, but they may not feel the review is complete (so they effectively want the flag to remain false).
I'd like to be able to read records in but set/default the value to reviewed (as a convenience) but due to the problems noted above, this doesn't seem possible.

beacuse i have pass in default system date it's working only with add row button.
How can i pass system date and time in update mode in tabular form.
Thanks

Hi,
You just create a trigger on the table on which you build your tabular form:
e.g:
CREATE OR REPLACE TRIGGER "AUDITING"
before insert or update on "MYTABLE"
for each row
begin
    if inserting then
        :new.created_on := localtimestamp;
        :new.created_by := nvl(v('APP_USER'),user);
    elsif updating then
        :new.updated_on := localtimestamp;
        :new.updated_by := nvl(v('APP_USER'),user);
    end if;
end;Regards,

Tabular form number validtion is not working

Hi,
I have an tabular form with updatable columns which has datatype as number. i have created the in built tabular form validation "Item/value specified is numeric" for this updatable columns.
when i entered any non numeric character like "asdasd" into this updatable columns. it shows me plsql error. PL/SQL: numeric or value error: character to number conversion error.
can you please help me on this?
Regards,
Nilesh

Hi,
If you enter "asdasd" and get PL/SQL: numeric or value error: character to number conversion error , it only implies the right thing is happening.
Maybe what you are alluding to is that the messages is not the way you want it. It should perhaps be "<column_name> must be numeric."
What do you have in the Error Message item of this process? If is it null you are likely to get the message of the type you are getting.
Did you by any chance try to change the default error message, which reads "#COLUMN_HEADER# must be numeric."?
Regards,

Hi,
For your scenario, you need to have two cellVariant as TableStandardCell (say successTSC & failTSC). Add tableCellEditors to these 2 TableStandardCell as you like. Mark there variantKey property as var1 & var2 respectively.
Do change the cellDesign as you like the color for the TableStandardCell.
Bind an attribute selectedVariant to your column selectedCellVariant property.
Now in wdDoModify you can write:
for(int i=0;i<wdContext.nodeCountries().size();i++){
if(wdContext.nodeCountries().getCountriesElementAt(i).getStatus().equals("SUCC")){
// Here node countries is the datasource of your table.
wdContext.nodeCountries().getCountriesElementAt(i).setVariantKey("var1");
} else if(wdContext.nodeCountries().getCountriesElementAt(i).getStatus().equals("FAIL")){
wdContext.nodeCountries().getCountriesElementAt(i).setVariantKey("var2");
The article below will definetly help you in your requirement.

Manual Tabular Form using checksum

I have a manual tabular form which updates OK but when I add the htmldb_item.mds_checksum it does not always work. It does not pass the MD5 checksum test in the update process. Sometimes it works some times it does not. No one else is updating this data so it should pass the checksum error.
I need a manual tabular form so I can to retrieve this same data in a collection if the page is submitted for a cascading dropdown in another region. That is correct?
Of course, I could do the cascading dropdown another way instead of select list on submit. This is puzzling me.
Here is the sql query:
select htmldb_item.hidden(1,sub_id) sub_id,
htmldb_item.display_and_save(2,column_id) column_id,
htmldb_item.display_and_save(3,column_name) column_name,
htmldb_item.display_and_save(4,primary_key) primary_key,
htmldb_item.display_and_save(5,required) required,
htmldb_item.select_list(6,isselected,'Yes;Y,No;N') isselected,
htmldb_item.md5_checksum(isselected) cks
from sub_columns
where sub_id = :P26_SUB_ID
order by 2
Here is the update process:
declare
l_cks wwv_flow_global.vc_arr2;
j pls_integer := 1;
begin
-- Get original MD5 checksum
select wwv_flow_item.md5(isselected) cks
BULK COLLECT INTO
l_cks
from sub_columns
where sub_id = :P26_SUB_ID;
for i in 1..l_cks.count
loop
if htmldb_application.g_fcs(i) != l_cks(i) then
rollback;
raise_application_error(-20001,
'Current version of data in database has changed '||
'since user initiated update process.');
end if;
end loop;
-- update Subscription
for i in 1..htmldb_application.g_f01.count
loop
update sub_columns
set isselected = replace(htmldb_application.g_f06(i),'%'||'null%',NULL)
where sub_id = :P26_SUB_ID and
column_id = htmldb_application.g_f02(i);
end loop;
commit;
end;
Any help would be appreciated. I just don't see what I am doing wrong and I don't see any other way to do it.

I had already read this paper before doing the tabular form manually. I tried to follow it as closely as I could. My tabular form is a little different since I have a where clause in my SQL and only updating one field. The other fields are display_and_save. And I was branching to a different page than the page containing the tabular form. I would think none of these differences should make it not work. I did change to branch to the same page. That made no difference.
I did not need to do an insert so I skipped doing that step and then went to Adding Optimistic Locking. It is failuring in my update process with this code:
-- Get original MD5 checksum
select wwv_flow_item.md5(isselected) cks
BULK COLLECT INTO
l_cks
from sub_columns
where sub_id = :P26_SUB_ID;
for i in 1..l_cks.count
loop
if htmldb_application.g_fcs(i) != l_cks(i) then
rollback;
raise_application_error(-20001,
'Current version of data in database has changed '||
'since user initiated update process.');
end if;
end loop;
I get the Error process message and then the above -20001 error message when I click on the Submit button. Is there something wrong with my above code? I would assume I would need to add the where clause to the above select since I am only updating whose records.
I had created a submit button with action submit page and redirect to URL. The process executes on the condition when the submit button is pressed.
I need to get this working soon. I would assume other people have done a similar thing. I have tried many things. Another thing I notice is if I tell it to not display the first column, sub_id, and the last column, cks, (unselecting display in Report Attributes section) then the update does not work. I must be doing something wrong but I don't know what.
I created the page with component, report, SQL Report, and region type SQL Query.

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).
