Automatic line extraction

• Treatment of automatic line and Fetch. Session variables are null.

  Hi all
  
  One of the pages in my application has a form based on a table that is implemented automatic assistance (DML) line treatment. The automatic line extraction and automatic updating properly.
  
  I can see the variables/fields on the user interface and when I use the DEBUG option
  However, I don't see any of these values, when I see the option of variables 'session' (at the bottom of the page).
  
  The problem is that I intend to write another process that will use these variables, and I can't do it. All values appear as NULL values for all other processes.
  
  Please advice as to what causes this problem and any possible workaround. I am aware of the possibility of writing my own extraction and update of the process, but I wanted to know if there is a way to use these variables.
  
  Thank you
  Rajesh.

  However, all page in Page 2 element values are currently zero.

  Once 'Submit you' page, you will see the values for page items in session state. Your custom process running after the ARP and before any process to reset the session state must see the defined session state values.

• ORA-01403: no given available problem when you use FETCH of AUTOMATIC LINE to fill

  ORA-01403: no given available problem when you use FETCH of AUTOMATIC LINE to fill out a form.
  
  1) has created a FORM on the use of assistants of EMP. This creates an AUTOMATIC FETCH of LINE
  NAME OF THE TABLE - EMP
  The PRIMARY KEY containing - P2099_EMPNO point
  Primary key column - EMPNO
  
  By default, automatic extraction has a "process Error Message' of"Unable to fetch line."
  
  (2) created an HTML region. In this region add
  text P2099_FIND_EMPNO element
  GET_EMP submit button
  The update branch the conditional branch created when the Create button to set P2099_EMPNO with & P2099_FIND_EMPNO.
  
  If I then turn the page, enter an employee in P2099_EMPNO number and press the GET_EMP button, the form is filled correctly. But if I get an employee who does not exist, then I get error oracle ORA-01403: no data found and no form but a message at the top of the page 'Action transformed '. I was expecting a blank form is displayed with the message 'Could not extract line.'
  
  In conditioning automated extraction so that it checks that the line exists first, I can work around that. Change the fetch EMP automated line so that it is conditional
  EXIST (SQL query returns at least one row)
  
  Select 'x '.
  from EMP
  where EMPNO =: P2099_EMPNO
  
  
  But this means that when the employee exists I must be get DB twice, once to the State, and then again for the extraction of the actual line.
  
  I can't change so I don't get the Oracle error, rather than work around for a above is there something? I wonder now if the automatic extraction of line is only supposed to be used when you bind a report to a form and that I should manually write the extraction process. The reason for which I don't have at the moment, it is that I'm trying to stick with the auto generation Assistant as I can.
  
  Any ideas?
  
  Thanks, Pete

  Pete:

  The process Assistant APEX (ARF, ARP etc) errors are generally not recoverable. The error encountered is simply displayed on a page by using the model of "Error Message. So as you said yourself, you create your own process line Fetch and have the opportunity to customize the management mistakes, or you paste a validation on the page to verify that a folder can be accessed for the views expressed.

• Behavior strange transformation process of automatic line (DML)

  Hi all
  
  I'm running a process with extraction transformation of automatic line (DML) on a synonym and it works perfectly but when I change the owner of the table, it no longer works and displays the error message:
  
  ORA-06550: line 1, column 17: PL/SQL: ORA-00936: lack of expression ORA-06550: line 1, column 9: PL/SQL: statement ignored
  Extraction of line cannot.
  
  
  I thought it might be the owner on this synonym permissions, so I give him all the subsidies, but still no luck.
  
  Anyone know if there are limits to the process of automatic line (DML)?

  Pedro,

  Think our responses crossed there, please take a look at my last post.

• APEX 5 treatment of automatic line (DML) update fails

  Hi all

  I need help because it seems I'm missing something to get this working:

  -J' have a page with a form that contains editable elements and some hidden items.

  -J' have a button on the same page, open a modal dialog box.

  -the modal dialog box contains a tabular presentation, including a process of "Dialogue."

  -button of the modal dialog box contains a 'closed dialog box"

  -There are 2 real actions:

  -L' code is running plsql for updating a hidden field called P210_DATE_MODIFIED with sysdate.

  -Send the Page using a query called SAVE_CARS.

  This kind of debugging things says:

  ... Session state: saved point new value "P210_DATE_MODIFIED" = "" 27.05.2015 14:55:44 ""

  and later:

  ... 'Row of CAMPAIGN_DATA process' process - Type: NATIVE_FORM_PROCESS

  ...... Jump as integrated type process condition evaluates to FALSE.

  (there are no conditions on this process.)

  The data is not updated.

  What does ""integrated process of type condition "means? "

  How can I know why there is no update running? I thought that this setting P210_DATE_MODIFIED a new value is enough to trigger the update.

  EDIT: Supported Operation has the value "Update" to fetch him the automatic line.
  

  Thank you and best regards,

  Gerald

  Hi Gerald,

  What is your (name of the button) submit button? It must be one of the following names for the type of build-in the condition evaluates to true.

  Update validates the values of request: SAVE, APPLY the CHANGES, UPDATE, UPDATE, MODIFY, APPLY, APPLY LINE of CHANGES %, GET_NEXT %, GET_PREV %

  Values of request for valid insertion: INSERT, CREATE, CREATE_AGAIN, CREATEAGAIN

• How to edit the automatic line processing (DML)?

  Hello

  I'm on Apex4.2

  I created a form on a Table with report and a form is using automatic line (DML) to add/change/remove treatment.

  I specified "trigger existing" as a source of a primary key column.

  How can I change it to "existing sequence" instead? Is it at all possible the?

  
  

  The other question is to know how to add an element to deal with by automatic line treatment?

  I added a column to the underlying table and corresponding page element. I need to write the default value of this object to the database.

  I added the name of the column in the Source of the page item definition. And it has the same value "Always, replace any value.."
  

  The element must be thouh "view only". If the value of the element is null, the default value must be written in the db.

  It doesn't work that way for a reason any. -What did I do wrong?

  
  

  Thank you.
  

  Hi Bloch,

  I'm on Apex4.2

  I created a form on a Table with report and a form is using automatic line (DML) to add/change/remove treatment.

  I said 'Existing trigger' as a source of a primary key column.

  How can I change it 'Existing Sequence' instead? It is possible at all?

  No, you can change the generation technique of primary key on the form of DML automated after creation.

  What is the problem with "existing trigger? Trigger is an elegant way to generate and manage your primary key.

  For example, take a look how you can generate a primary key with trigger:

  create or replace TRIGGER BIU_EBA_DEMO_FILES
     before insert or update on EBA_DEMO_FILES
     for each row
  begin
     if inserting then
         if :new.ID is null then
           select EBA_DEMO_FILES.nextval into :new.id from dual;
         end if;
         :new.created := localtimestamp;
         :new.created_by := nvl(wwv_flow.g_user,user);
     end if;
     if updating then
         :new.updated := localtimestamp;
         :new.updated_by := nvl(wwv_flow.g_user,user);
     end if;
  end;
  

  The other question is to know how to add an element to be processed by the transformation of the automatic line?

  I added a column to the base table and corresponding page element. I need to write the default value of this object to the database.

  I added the name of the column in the Source of the page item definition. And it has the same value "Always, replace any value.."

  The element must be thouh "view only". If the value of the element is null, the default value must be written in the db.

  It doesn't work that way for a reason any. -What did I do wrong?

  I agree with Jitendra solution to add a new element to shape DML, to be processed by the transformation of the auto line.

  But I would like to add that the article is "Display Only", check if the settings section of the element-> property to save Session State is set to "Yes" as it will help in the treatment of the form.

  Finally, if you still want to go to the primary key generation technique using 'Existing Sequence' and add new items to the form as well, why do you consider not deleting existing shape and recreate the shape with options that your choice and with the same page number.

  I hope this helps!

  Kind regards

• How to copy a record with a treatment of automatic line (DML)?

  Hello
  
  I want to duplicate (copy) a record.
  
  I have a form with an automatic line processing (DML), look for the PK stored in an element named P26_ID and filling of the values in the corresponding elements of the form.
  
  I have an automatic line processing (DML) that allow to update, delete and change the line.
  
  So far so good.
  
  I thought it would be good if I calculate a new value for the PK and stored in the P26_ID.
  
  Then I thought that the automatic treatment of the line (DML) would see that this 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 P26_ID element is of type database column; so I went to another element named P26_ID_NEW and put this new pk in this article. I then created another automatic processing line (DML), triggered by this button, and who will look at this new element. It doesn't work any more.
  
  Where can I go wrong?
  
  Thank you very much for your 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 in the form, you can do the following to duplicate this record

  (1) define a button named "duplicate".
  (2) set the goal for this button to be "URL".
  (3) set the URL for this button to be
  JavaScript:Duplicate();
  (4) add this piece of JS in the header of HTML page

• See APEX SQL for the treatment of automatic line

  Hello
  
  I get an error like this when you try to update with the automatic processing of line:
  ORA-20505: DML error: p_rowid = 89, p_alt_rowid = network_user_mou_id, p_rowid2 =, p_alt_rowid2 is. ORA-06550: line 1, column 17: PL/SQL: ORA-00936: lack of expression ORA-06550: line 1, column 9: PL/SQL: statement ignored
  Is there a way to see the generated SQL code so that I could determine what the problem is?
  
  Thank you
  Rick

  Rick:

  A way to see the SQL code executed would be to allow "sql_trace" before the process of automatic processing of line. Create a process that fires off the coast before before that the process of automatic line with the following line of code

  alter session set sql_trace=true;
  

  and a process that fires off the coast after the process of automatic line to disable tracing

  alter session set sql_trace=false;
  

  Trace files will occur in the "bdump" or "udump" Directory depending on whether you are using the EPG or OSH.

  As for the error itself, I wonder if it is due to a column that you recently added to the form.

• Where is "MEMORY_CACHE" of automatic line Fetch?

  Where is the cache memory used to store temporary session for purposes of rendering State by APEX?
  
  I'm trying to set up a generic process that will inspect current values used on a page to make it. Session state for the currently rendered page with the value extracted from the automatic extraction of lines is saved in a temporary location. These values are not validated to session state (for example wwv_flow.data) until the page is submitted, the values are passed in a URL, or apex_application.set_session_state (...) is used. This behavior is defined by the wwv_flow_dml.fetch_row (..., p_dml_fetch_mode = > 'SET_MEMORY_CACHE_ON_FETCH',...).
  
  Where is - this "MEMORY_CACHE"? I have carefully considered through many of the package specification in the FLOWS_03XXXX schema and found no indication in this regard.
  
  This temporary session state must be stored somewhere that it can be accessed or modified in the calculations of APEX, procedures and areas of PL/SQL using bind variables (e.g.: P200_ITEM_NAME).
  
  I, however, am not in any PL/SQL that APEX will run directly or know what elements on a given page should be read/change up to the time of rendering/execution of the page. Thus, the use of variables to statically link type is not a solution. I have however to try to create the dynamic SQL via DBMS_SQL and try to fill in this dynamic SQL with flows_030100.wwv_flow_utilities.perform_binds bind variables, but this did not work.
  
  Thoughts?

• Apex 5.0.2 error when changing the table name in the treatment of automatic line of process (process row)

  Hello

  I need a little help...

  For some reason, I have to change the underlying table for a treatment of automatic process (process Row) line (form).

  Although such a change is possible in the designer of the page (under "settings") Apex does not recognize the new name of the table, but seem to rather use the name of the original table "old."

  Pretty strange (new/modified) (the new table columns) are (correctly) error message.

  For example, the 'old' is: TABLE_1 and TABLE_2 new.

  TABLE_2 has a new COLUMN_NEW column (and corresponding P1234_COLUMN_NEW page element exists)

  Then the error message says something like: not found COLUMN_NEW column in TABLE_1. Althougt I changed the table to be TABLE_2.

  Maybe it's a bug or I do something wrong about this?

  Thank you in advance!

  André

  OK, just to get some - you changed the name of the table twice:

  -Rendering of section--> Page1234: Pagename--> pre-rendering--> after the header--> process of--> line from TABLE_2

  -Treatment article--> treatment--> process--> process of line from TABLE_2

  I thought, that always seek you the line of TABLE_1

  Hi all

  I don't understand what it should in fact?

  newbi_egy wrote:

  What is the meaning of values insertion automatically? is not this means that I can insert values with my hand without coding.

  I want to write values to the elements directly? right?

  This means that if the insert is one of the operations allowed the ARP and the page is sent with a value of QUERY INSERT, CREATE, CREATE_AGAIN or CREATEAGAIN, then a line including the elements page, provided a source database column will be inserted into the table specified in the source of the ARP.

  It is 'automatic' because you do not have to write code, and it determines what DML operation to apply according to the value of the sent REQUEST.

• Mowing of automatic line with above forms (fillings)

  Hello guys

  Hello

• Automatic line of the dynamic table numbers

  Hi, with your help I've almost finished my table. My table has 18 rows and there add line btn. Is it possible automate so that when I add lines they will have numbers of numbering of the lines automatically. I tried the indexing, but it does not work.

  this.rawValue = this.parent.index

  I am trying to improve also a calculation script and for some reason I get and error. Will you be able to let me know what is wrong. My script is:

  Form1. SubTable.Table2.Row1 [0]. Total::calculate - (FormCalc, client)
  If (AmountNet > 0) then
  Total = AmountNet + VAT

  else (AmountNet == 0) and (rate > 0)
  Total = AmountForeign /ExchangeRate
  endif

  I checked with the check script syntax and it's ok, but I still get an error.

  I have attached a picture of what I get a a final doc.

  Thanks a lot for your help!

  Hello

  Looking at the form once again, I think that's what you're after:

  if(AmountNet > 0) then
  $ = AmountNet + VAT
  else if ((AmountNet is null or AmountNet == 0) and rate of change > 0) then
  $ = AmountForeign / exchange rate
  endif

  In the previous version, the test was "when AmountNet == 0; However this does not check if the field was empty. The code above in red AmountNet checks two conditions: If the field is empty OR if the user has put in £0.00. If one of them is true, then the first part of the test is satisfied. The script moves to focus on the value of the ExchangeRate separately.

  Hope that helps,

  Hi all, I do not understand what it should in fact?

  Otherwise, how will he know what line to select and display?  If look at the process, you will see that it is the page that contains the primary key for the table, so APEX expects this value to retrieve the row of data...
