Page having PL/SQL process and Automatic Row Process for 2 different tables

Hi,
I have a page containing 2 regions A & B.
Region-A content would be updated to table T1(PK : Ticket#).
Region-B content would be inserted into table T2(PK: Attachment# ; FK: Ticket#).
Region-B is used for uploading a file content into T2.
Since I cannot use 2 DML processes on the page for 2 different tables with a common column, so I have a PL/SQL process to update the record into T1 and an Automatic Row Process(DML) for inserting into T2.
Now the issue is in Region-B when I select a file using 'Browse' button and click on Upload button to fire the Automatic Row Process, the success message is displayed but the file is not uploaded into the table. But when I moved the entire Region-B and the Automatic Row Process to a different page and clicking Upload is working fine and inserting the record into the table along with the file content.
An item P10_TICKET_NUMBER with source type as Database column with source value as TICKET_NUMBER is used in Region-A.
I have gone through the forums and found some of the threads below
Re: 2 Automated Row Processes for one page?
Re: Error when trying to create 2 Forms on same page on 2 tables with ID as
where people facing similar issues but here I have followed the solution provided(with one PL/SQL process and other Automatic process) in the threads but still issue persists.
Can anyone throw some light on this please.

Get row count for different tables to the same line

How can I get the row count for different tables in one line:

SQL Loader and control file changes for different users

In the front end of my application I can select a data file and a control file, and load data to the table mentioned in .ctl file. Every user who logs in uses the same .ctl file and so loads onto the same table. Now I want the user to load data onto the table in his own schema. I can get the username of the user currently logged in and i want to insert it into that username.table. So can i copy the contents of the .ctl file into a variable, modify it into username.table in that string and pass that variable as a parameter to the sqlldr command instead of the .ctl file.
Or is there a better way how I can modify the same control file everytime to change tablename to username.tablename in .ctl file and pass to sqlldr to load data to table in local user schema table.
Thanks and Regards

Thanks for the reply .. user do have their user credentials but only for the application ... but all users use a common loader and control file once they log into the application. So irrespective of which user is logged in he selects the same control file and loads to the same table mentioned in the control file .. i instead want user to be able to load to the table in control file but into his schema like username.tablename instead of just the tablename mentioned in .ctl file.

Edit SQL generated from Automatic Row Processing (DML)

Is there any way to see/edit the insert/update SQL that is run when using the "Form with Report" wizard ? I've used the wizard to generate a list of rows from a table, with edit buttons next to each line. The Edit button links to a detail screen where the user can Create/Update/Delete.
I have NOT NULL fields on each row that are auto-populated using triggers, so they are marked as read only on the Detail screen, but set to Optional since the user is not required (or even allowed) to set them. This works for inserts, but when App Express does an update, it sets the fields to NULL (or so I assume, based on the error message), so the update fails.
The whole point of using this tool was because the wizards make it so easy to put screens up, I hate to have to write it myself....
I don't understand why the tool would set the fields to NULL anyway, when they have values already. If all fields need to be updated, it should just update them to their current values. Am I missing something here?

Well, scratch that. I wrote too fast.
Tabular form doesn't work either.
Is there any way to make a non-updatable column updateable AFTER you use the Tabular Form wizard?
Is there any way to allow the user to define the Primary Key? I've tried to make the field updateable, or even just show it, but the system does not hold my changes on save.

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..

Bug Report: Automatic Row Fetch/Automatic Row Processing and invalid column

Hi,
if an invalid column name is specified for a page item of type "Database Column", no error is reported by the Automatic Row Fetch/Automatic Row Processing process. It's just ignored and nothing is returned!!! That makes it kind of hard to identify such an error.
The problem can happen for example when a column is renamed or if there is a typo in the column name during creation.
The problem seems to be related to the following query which doesn't use an outer join.
SELECT C.COLUMN_NAME, C.DATA_TYPE, I.NAME, I.FORMAT_MASK, I.DISPLAY_AS
FROM
SYS.ALL_TAB_COLUMNS C, WWV_FLOW_STEP_ITEMS I WHERE C.OWNER = :B4 AND
C.TABLE_NAME = :B3 AND I.SOURCE = C.COLUMN_NAME AND I.SOURCE_TYPE =
'DB_COLUMN' AND I.FLOW_ID = :B2 AND I.FLOW_STEP_ID = :B1 AND (C.DATA_TYPE
IN ('DATE','NUMBER','CLOB','LONG','FLOAT') OR C.DATA_TYPE LIKE 'NUMBER%' OR
C.DATA_TYPE = 'CHAR' OR C.DATA_TYPE LIKE '%VARCHAR%' OR C.DATA_TYPE LIKE
'TIMESTAMP%') ORDER BY C.COLUMN_IDBTW, if an invalid table/view name is specified for a Automatic Row Fetch/Automatic Row Processing process, the error message during runtime isn't very speaking.
ORA-06550: line 1, column 17: PL/SQL: ORA-00936: missing expression ORA-06550: line 1, column 9: PL/SQL: SQL Statement ignoredMaybe that could be changed too.

Automatic Row Processing - Preset a value with value from other page

Hi everybody,
I have created a form on a table with report. I added a dropdown field to a sidebar region on the first page the groups and selects only a couple of these entries. (Think: only people for the department selected in the drop down field). Now when I click on the normal create button the id field for the department should be filled automatically with the value from the page before, where something was already selected in the drop down field. The id field is a hidden field on the actual create page. Maybe it is not working because the field is linked to the database column to make the automatic row processing work or something. I tried computions on both pages and setting the values. Nothing seems to do the trick.
Any help would be greatly appreciated.
Thanks,
Henrik

Hi,
these are the values I currently see:
108 14 P14_SELECTEDSS Display as Text (escape special characters, does not save state) No
108 14 P14_CHARACTERISTIC_ID Hidden and Protected Reset to Null No
108 14 P14_SHAREDSERVICE_ID Text Field 30 Inserted No
108 14 P14_CAPTION Text Field No
108 14 P14_CATEGORY_ID Select List No
108 14 P14_WEIGHING Text Field No
108 14 P14_DESCRIPTION Textarea No
I also have to say that I deleted the computations I created earlier again cause they did not work and I had the same values for these variables. I am trying to (pre)set P14_SHAREDSEVICE_ID to P13_SELSS when I click the create button on page 13.
Thanks again,
Henrik

Automatic Row Processing and Casade Delete

I have Automatic Row Processing for delete on a table, however I have FK's dependent on this table. How do I do a cascade delete using Automatic Row Processing DML for a delete ?
Any way besides writing a trigger ?

My fault, my constraint was not written properly to indicate on delete cascade.

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 fetch error (ORA-00936: missing expression)

Hi there,
I have a bit of a problem setting up automatic row processing. The Apex processing is causing an error, but I'm not sure what PL/SQL code is being run (obviously, I don't have access to the Apex code) and all I get is the error following:
0.13: Processing point: AFTER_HEADER
0.13: ...Process "Notes load": DML_FETCH_ROW (AFTER_HEADER) F|#OWNER#:PUPIL_NOTE:P29_PUPIL_ID:PUPIL_ID:P29_ACHIEVEMENT_SET_ID:ACHIEVEMENT_SET_ID

and then the following exception report on the page:
ORA-06550: line 1, column 17: PL/SQL: ORA-00936: missing expression ORA-06550: line 1, column 9: PL/SQL: SQL Statement ignored
Can anyone tell me how I can diagnose the problem?
Many thanks,

Are 'read only' items causing my automatic row processing to fail?

I have a form that uses automatic row processing to update my table.
I recently had to add a check to lock down the fields using the read only condition where a record has been 'approved'. So, I turned off all of the fields and hid the update button.
Now they want me to check to see if the user is a manager, and if so, allow them to see the update button, and make a single field on the form modifiable.
I have the user identified as a manager, and can make the field accept the change (a yes/no combo box). Yet when they click the update button, the form just sits there. A branch is supposed to fire on hitting that button, taking them back to the previous report, but it doesn't happen. The source of the combo box in question uses a column on the table, and works fine when the form has all of the fields showing for modification.
I had some validations that I finally set to never fire, thinking that they were failing and just not giving the error messages. I know a bad sql or pl/sql atatement in a validation will cause the form to just keep sitting there doing nothing, and thought it might help.
Several of the various fields are combo boxes, several are text boxes.
I'm stumped.
Shall I keep the regular update button hidden whether it is a manager or not (because it has been 'approved'), and enable a new button that fires off a process to update the one field that the manager may want to change? Does making a field 'read only' always have a detrimental effect on the auto processes I've been counting on? Is that if fact what is happening now?
Thanks in advance for any advice or comments on this.

Hi, Scott.
My version is 3.0.0.00.20
I have received info to set up the application, though I have not activated it as yet. I'm reluctant to try to load up the various tables to make it work. It could be done.
My workaround is to that the user (a manager) fires off to another form to show an individual record, and ask if he/she really wants to make this change. On submit, they will be taken back to the original locked down form, and I will update the single field in that process of returning them. This will actually be a plus, in that I expect to show them all of the 'duplicate' entries for that item, and show them that by 'activating' this particular item, they will 'deactivate' the one duplicate that is currently active. Or, if they are deactivating the sole item that is active, that there will in fact be no active items in the system. Convoluted as heck, but they swear this is how they've been doing business with their briefcases and file cabinets of Excel files. I'm surprise they even float at this point (these are ships we're talking about).
This all may be due to the form originally having a next/previous/count process once arrived at my clicking on the edit button of the report of items. All of that has been hidden away, and though the fields exist of the form, they are not used. They only see the current item that they clicked on from the report.
I read up a little on session state, as well as posts with the debug error I was getting. I'm still not on board with the whole issue of 'state'. Items stay as they are until they're changed, no? I suppose that sounds simplistic.
One of the things that caught my eye was several combo box lists that on read only mode, showed [] square brackets. Which, in some cases is okay.
What I'll try to do is set up a public application - for future use if nothing else. I'm going to be working on this for awhile. I have more than a bit of work to do to cleanse the data as well as get rid of the single sign on requirement (I'll assume that I should have to do this) in order to share the app.
I know you're expecting me to have this up and running for you to look at, but I'm under the gun. And they actually like my workaround.
I'll keep everybody informed, one way or another.

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.

Automatic row processing insert fail

Hi all,
Application Express 3.2.1.00.11
Oracle Database 10g Release 10.2.0.3.0 - 64bit Production
I am running into a problem where my automatic row processing will update and delete records but will not insert. I get the following error.
ORA-44003: invalid SQL nameI disabled all triggers and added the appropriate fields to my form and manually entered correct data and am still having the issue. I can run a trace but only the dba has access to retrieve the file and he is gone. Any suggestions on where to start? i checked debug mode and it is definitely hanging on the ARP.
Cheers,
Tyson Jouglet

All,
Finally fixed it!!! So if you experience this problem, double check all of your item sources. I was upgrading a date column to a timezone column and subsecuently made it three different items. Long story less long, I left the original date item on the form and deleted the source column name but i forgot to change the item source from database column to something else. This will not effect how apex deletes or updates a record but it will not allow you to insert a new record. I know this is a user error, but maybe this could be added as a validation?
Cheers,

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
SHY

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 (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?

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.
