Automatic DML process Apex 4.1

Hello,
I'm using apex 4.1.
Stuck on the below issues,
1) Automatic update (DML) is not working when branching from page 1 to page 2. Value is not saved in both the pages.
2) Automatic Fetch (DML) is not working on page 2.
Please suggest the work around.
Best Regards,
Girish

I have a workaround: Pass the success/failure message via a page variable on the target public page. This works.
However, this is only a workaround, it bypasses the built-in Apex behavior. The real fix would be for Apex to pass success/failure messages properly.

Automatic Row Processing (DML) process is not updating the record

Hi all,
I have an application which was working fine last week and tested and backuped to new application. This Monday, one of the form in that application is not updating the data all of a sudden. I debug that by having page 0 variable and assign the value from the column variable to page 0 variable. Whatever value I changed to the column variable was getting updated to page 0 variable. But it is not updated in the database. So, I changed the success message of the "Automatic Row Processing (DML) process" and I can see the success message on the page, but the column value does not get updated. But when I go back and checked my backup application, that page is working fine. For now, I copy that from the backup application, but I would like to know why this is happening?
Thanks

Hi Scott,
Thank you very much for your response. Because of the database complexity, I can't create/import the application on the apex.oracle.com. I am just wondering why this is happening. One of my coworker said same thing happened to her in one of her project and it gets resolved once she restart the server. I am not able to restart the server to check and see if this resolved as the application is on the client server. Do we need to clean up any log file? Thanks.

Automatic Row Processing (DML) - Return Key Into Item

Hello,
This question is on Apex 4.2:
I'm Displaying the [UNIKEY] column value after the record is inserted into the table using :
page process > process row table_name > Source: Automatic Row Processing (DML) > Return Key Into Item > "Item Name"
This works fine while inserting records, my question is why this does not respond on update / delete ?
ϯ LT

Check your branches.
What might be happening is that on insert and update an other branch is followed.
Where the branch of the insert either isn't clearing the cache of the page or is setting the item with it's own value.
The branch on the update on the other hand is clearing the cache of the page and not setting the item.
With a delete there is a clear cache process generate by the wizard. Check if this process is only running on the delete and not on the update.
From memory the process is called something with reset.
If the above doesn't help try to replicate the problem on apex.oracle.com and give access with a guest developer account so we can have a look.

Automatic Row Processing (DML)

Hello,
I have an Automatic Row Processing (DML) in a page, but I forgot to add a column in the table where I record the data. So I added the item that I forgot in the page but when I tried to insert the data on the table it shows me this error: ORA-06550: line 1, column 146: PL/SQL: ORA-00904: "PCD": invalid identifier ORA-06550: line 1, column 13: PL/SQL: SQL Statement ignored. I think this is because the column is missing in the "insert query", so I'm wondering how can I add that column in the query... in the automatic row processing it does not show me how can I add that... in the source type in the item that I want to add... I selected Database column.. so the problem is not from there... thanks in advance.

Hi,
do you mean the "Oracle Employee ACE" icon next to my name? That's not something you can set on your own. Before I joined Oracle I was an Oracle ACE Director which was converted to an Oracle Employee ACE as soon as I started working for Oracle.

Automatic Row Processing (DML) Update problem

Hi All,
I am using Oracle 10.2.0.3 on Windows Server 2003 with "Application Express 3.1.0.00.32".
I have two schemas in the database, A and B
B has all the tables which holds the production data
A has all the synonymns for all of B's objects and plus insert, delete, update, execute rights on B's objects.
I have a view MyView which basically reads from a table from B's schema
and an APEX form based on this view... so far so good.
Problem is when I generate a form using form wizard and try to update a record in the table in B's schema, I get the following error: I cannot use B as the OWNER in APEX, because for other reasons, I need to use A.
Automatic Row Processing (DML)
ORA-20505: Error in DML: p_rowid=CA-4837-AHU-002, p_alt_rowid=OBJ_CODE, p_rowid2=, p_alt_rowid2=. ORA-20503: Current version of data in database has changed since user initiated update process. current checksum = "97813992F558009979B5B86C925AD4AC" application checksum = "FA8AB5EC759780B0048E2C11584CD5E6"
Does anybody know why I get this error message? Is it possible to update the table using the view? I know for sure that my browser is not caching the data and someone else is not editing the same record.
Thanks in advance,
Sinan

Hi,
Problem is when I generate a form using form wizard and try to update a record in the table in B's schema, I get the following error: *I cannot use B as the OWNER in APEX*, because for other reasons, I need to use A.As highlighted, you need to grant insert, delete, update, execute rights on B schema's objects to APEX schema. Also, you may need to use "Instead of" trigger for view.

Automatic Row Processing (DML) using synonym name instead of table

I want my APEX form to select info using the table name but perform all the DML (add, change, delete) using the synonym name. I created the form using the wizard and went into the "Process Row of xxx" process that was created. I tried changing the table name to synonym name under the 'Source: Automatic Row Processing (DML)' section, but it still uses the table name. Is this possible or do I need to manually create processes using the synonym names

Hi,
when I change the Table Name property in the "Automatic Row Processing (DML)" process to a non existing table it raises an error when I run the page and try to save something. So it's actually using the value.
Does the synonym point to the same table or a different table? What is the intention behind selecting from the table but updating through the synonym?

Automatic Row Processing using Apex?

Hi All,
I am in build forms in apex during that scenerio i am creating the Process as "Automatic Row Processing (DML) but it is not working.. Or in other words assume that in form i have 5 text items and a button.. Now when i give empno and clik on button.. the deatils should be fecthed for that empno deatils using "Automatic Row Processing".
I have tried in google but i am not able to get the any proper way to resolve it..Can anybody help me out to resolve it..or if any links which may help me to find out the solution..
Thanks,
Anoo..

Yes..I have done.. but the problem is some times it is fetching and at all. So i thought to have a clear idea for fetching the data through Automatic fetch process..

Inserts using Automatic Row Processing (DML) should not clear cache

Hi,
I am using APEX 4.0.1.00.03.
I created a form on a table for inserts and updates.
After I do an insert, the Automatic Row Processing (DML) clears cache for all items on the page.
But the user wants to see the data he inserted without having to query. How can I achieve this?
Thanks
Chandra

There isn't any "reset page" process on my page.

Without Automatic Row Processing (DML)

Hi All
I try to make one page to show use DML statements without standard Automatic Row Process.
What I have:
One page with:
region: Report - select empno, ename, sal, deptno from emp;
region: Form with items: p6_empn, p6_ename, p6_sal, p6_deptno
addictionaly in that moment I have:
process CreateProcess:
begin
insert into emp (empno, ename, sal, deptno)
values (emp_seq.nextval, :P6_ENAME, :P6_SAL, :P6_DEPTNO);
commit;
end;
and button CREATE.
Create Process is fired when I push CREATE button and Insert statement works corecctly. Branch is on the same page. (I use request).
Now I would like to show update and delete statements.
In Report I have in column EMPNO standard button Edit (each row)
(<img src="#IMAGE_PREFIX#edit.gif" alt="Edit">)
I have process SelectProcess:
begin
select ename,sal,deptno
into :p6_ename, :p6_sal, :p6_deptno
from emp
where empno = :p6_empno;
end;
It is fired In Load _ Before Header
When I push Edit in one row I would like to see details of employee in Form, but I see nothing. In session state all is correct - I see :p6.... with name, sal and ...
I dont know how to connect this process with buton and branch.
could you help me?

Hi,
I have done a quick test for this - [http://htmldb.oracle.com/pls/otn/f?p=25946:1]
On the Edit page, I have a process called P2_LOAD_DATA that runs "On Load - Before Header", is conditional on P2_EMPNO being NOT NULL and using the following code:
BEGIN
SELECT EMPNO, ENAME, JOB
INTO :P2_EMPNO, :P2_ENAME, :P2_JOB
FROM EMP
WHERE EMPNO = :P2_EMPNO;
END;I have a button with a Button Name setting of "UPDATE" (user sees this as Apply Changes)
I then have a process that runs "On Submit - After Computations and Validations" and is conditional on REQUEST = UPDATE. The code is:
BEGIN
UPDATE EMP
SET ENAME = :P2_ENAME,
JOB = :P2_JOB
WHERE EMPNO = :P2_EMPNO;
END;The source settings on P2_EMPNO, P2_ENAME and P2_JOB are as I described in my previous post.
One thing to check - do you have a "reset page" process? If so, remove it.

Strange behaviour Automatic Row Processing (DML) process

Hi all,
I'm executing a process with a fetch Automatic Row Processing (DML) over a synonym and it works perfectly but when i change the table owner it doesn't work anymore and give the error:
ORA-06550: line 1, column 17: PL/SQL: ORA-00936: missing expression ORA-06550: line 1, column 9: PL/SQL: SQL Statement ignored
Unable to fetch row.
I thought it could be from the permissions of that owner over that synonym so i give it all grants, but still no luck.
Does anyone knows if there are some limitations for the Automatic Row Processing (DML) process?

Once again thanks for the reply Munky,
The original table created on schema1 (ADMGIN) :
SQL> desc MAN_ALT_TAB
Name Null? Type
ALT_ID NOT NULL NUMBER
ALT_DES VARCHAR2(50)
AAT_COD NOT NULL VARCHAR2(10)
ALT_ID_REL NUMBER
ALT_MUL_REG VARCHAR2(1)
ALT_FOR_DES VARCHAR2(4000)
The synonym created in schema2 (PORTAL) :
CREATE OR REPLACE SYNONYM "PORTAL"."MAN_ALT_TAB" FOR "ADMGIN"."MAN_ALT_TAB";
Grants on the schema1 (ADMGIN) owner:
GRANT ALL ON MAN_ALT_TAB TO PORTAL;
There isn't a new table in the schema2 only a synonym.
The synonym isn't created in schema1 it was created in schema2.

How to copy a record with an Automatic Row Processing (DML) ?

Hi,
I want to duplicate (to copy) a record.
I have a form, with an Automatic Row Processing (DML), looking for the PK stored into an item named P26_ID and populating the values into the corresponding items of the form.
I have an Automatic Row Processing (DML) which permit to update, delete and modify the row.
So far so good.
I thought it would be good if I calculate a new value for the PK and stored it into the P26_ID.
Then I thought the Automatic Row Processing (DML) would see that it is a new value for the PK and would "decide" insert a new record.
But it does not work like that. I thought it was because the item P26_ID is database column type; so I switched to another item named P26_ID_NEW and put this new pk into this item. I then created another Automatic Row Processing (DML), triggered by this button, and which will look into this new item. It does not work either.
Where do i go wrong ?
Thank you for your kind help !
Christian

Christian:
Assuming that the 'Duplicate' function is available only when the page is in 'Edit' mode, ie. a record has already been loaded into the form you can do the following to duplicate this record
1) Define a button named 'Duplicate'
2) Set the target of this button to be 'URL'
3) Set the URL for this button to be
javascript:duplicate();
4) Add this bit of JS into the page HTML header<script>
function duplicate() {
$s('<name_of_PK_page_item>','');
doSubmit('CREATE');
</script>Varad

Solved: Delete Using Automatic Row Processing

See Scott's reply below for the answer.
Hi there,
I have an application built in APEX 3.0.1 that I would like to be able to use a button to delete a single row from an underlying database table (owned by the parsing schema).
My APEX page has a 3 HTML regions on it:
1. Only a Select List and Go button for User selection (of Debit Note)
2. Ten display Items (Text Field, Disabled saves state) displaying further information about User selection
3. Conditional Delete button (region with custom image) - only displays when P73_DEBITNOTEID is NOT NULL
I'd like this button to be used to Delete the Selected Item and thought I'd be able to use a Data Manipulation Page Process - Automatic Row Processing (DML) page process to do this.
However, when I go through the wizard the Select item containing primary key column value field has no values in the search list.
My first question is why was there no values in the list?
So I manually entered the Item I required (P73_DEBITNOTEID) but when I run the page and click the button I get a PL/SQL missing expression error.
What is the best practice method to do DML actions on the underlying database tables. The tables are all owned by the parsing schema.
Your help in resolving this matter would be greatly appreciated.
Kind Regards,
Gary.

Gary,
The DML processes (and the creation wizards for them) are for use with items having source type Database Column. If your page items don't use this source type, then neither the Automated Row Fetch nor the Automatic Row Processesing (DML) process types will work.

Automatic Row Processing (Update not running)

I have an Automatic Row Processing routine that returns the success message, but it never performs the updates.
I Put a special message in the Process Success and Failure Messages and the Success message comes up everytime with no database updates happening.
I changed the table name to a table that DOESN'T exists just to see if the failure message appears and I still get the Process Success Message.
Any ideas why the DML say's it's success when it's not doing anything?

Edited by: spuchc on Jun 4, 2010 7:48 AM

That doesn't appear to be the issue.
When I update the data for the of views on the page they work fine and have specific button names.
Also I've tried used PL/SQL Expression instead of button controls to fire the DML and it does fire.
Since it's not generating the update statement (when I look in V$SQL), why would APEX even given me back a "Success" message?
Also when I change the view name in the DML process to a bogus name, it still tells me "Success".
I'm going to look at calling my backend API's directly without the Apex DML because I've tried everything I know and it's just this one view that won't updated.

Automatic row processing updating my primary key

Hi all!
In Apex 3.2, I've got an Interactive report with a DML form on a table. My table has a primary key which use a sequence (trigger based). When I created my forms, I specified that I wanted to use an existing trigger as the source type of the primary key.
When I try to create a record, it work. If I try to create a new record and save, my trigger give me an error message because the automatic row processing is trying to update the primary key too. (My trigger on the update specify that the primary key should not be updated).
So my question is : How can I make the automatic row processing update everything but the primary key ? (I noticed that I could have asked APEX to use my SEQUENCE directly instead of the trigger (in the creation Wizard). But I dont know how to change this now that my form is created.)
Is there a source type that I can change in my primary key item ?
Note : My primary key item (id_emp) is protected and hidden. If I display it as "Display only", the update works... But I dont need to see id_emp on my form.

OK,
From your first post, it sounds as though the process is trying to perform an INSERT rather than an UPDATE. It is, therefore, trying to create a new record using a primary key that already exists on the table.
If that is the case, then we need to go through the points along that route:
1 - when you load a record into the page, the primary key page item should be given a value. So, firstly, check the link is populating the correct page item. And then, when the page has loaded, click the Session button on the Developer's toolbar at the bottom of the screen and check that the value is there
2 - when the page loads, one, and only one, page item should have the primary key value. This should be P3_NO_EMPLOYE*. Check other page items to make sure that their source is not NO_EMPLOYE. Again, check with using the Session button to see if the value appears anywhere else on the page
3 - when the page loads, the "SAVE" button should become visible. Check that this is conditional on P3_NO_EMPLOYE being NOT NULL
4 - there should be one, and only one, button that triggers the SAVE action. Check that there are no other buttons that either (A) are called SAVE or (B) trigger the INSERT SQL database action
5 - when the SAVE button is clicked, the "Process Row of..." process should be triggered and, because the button is SAVE and, therefore, sends "SAVE" as the REQUEST value, the process identifies this request as an Update database action. Check that you have Update ticked on the process and that you only have one process that can perform the update
6 - it is possible to change the value of the Request after a button has been clicked, so check that you have no computations or processes that run before the "Process Row of..." process

Processing Static (via automatic row processing) & Dynmaic fields

Hi,
I have a page that has 2 sections. Section S is statically driven which I'd like to process via a Automatic Row Process DML. Section D is for dynamic fields which I process via a PL/SQL script.
I need to process Section D (dynamic) first.
Now they're 2 things that I'm noticing when I try this. Can someone please confirm.
- After my process of Section D it seems to make a commit. I know this since I have a error in Section S, and the values from Section D are committed to the DB. I need to make sure a commit only occurs after all page processes have completed error free.
- My Automatic Row Process DML for Section S doesn't seem to work at all. It can't seem to read the values at all. I know this since I have several columns which are "NOT NULL" and the appropriate error messages are being raised. The Automatic Row Fetch for Section S does work properly.
For the time being the work around is writing a process for the entire page which includes both Section S and Section D. The thing is I thought that HTMLDB would be able to help me out a lot with Section S since it had static fields etc.

Martin - I would try to debug these two processes separately. If the Auto DML process isn't firing, perhaps the button used to submit the page isn't setting the request to one of the standard values recognized by the Auto DML package ('INSERT','CREATE','CREATE_AGAIN','CREATEAGAIN' for inserts and 'SAVE','APPLY CHANGES','UPDATE','UPDATE ROW','CHANGE','APPLY' or like 'APPLY%CHANGES%' for update).
A commit happens whenever session state is changed, so if your process saves an item value, that would do it. If you think that is not the cause of the commit, let me know the details of the process and I'll take a closer look. There is no way to prevent the commit when session state is updated.
