Delete records in Page view

Hello

I created a page to display. Created only VO. I added a column with the deletion icon to perform the deletion for the selected record. I added the following code to delete, but does not work. Here is expected to create for this VO EO perform the remove operation?

Please check following code.

CO:

{if ("Delete". Equals (PageContext.GetParameter (EVENT_PARAM)))}

String rowTemplateID = pageContext.getParameter ("TemplateID11");
[Serializable] param = {rowTemplateID};
throw new OAException ("Tempalate with id" + rowTemplateID + "deleted successfully", OAException.CONFIRMATION);
am.invokeMethod ("deleteRow", param);

throw new OAException ("Tempalate with id" + rowTemplateID + "deleted successfully", OAException.CONFIRMATION);
}

AM:

{} public void deleteRow (String rowTemplateID)

try {}
OAViewObject vo = (OAViewObject) getChartTemplatesVO1 ();
Line ChartTemplatesVORowImpl = null;
Number of selectedTempId = new Number (rowTemplateID);

int fetchedrowcount = vo.getFetchedRowCount ();
System.out.println ("Number of rows read is" + fetchedrowcount);
getOADBTransaction () .writeDiagnostics (this, "number of lines is = >" + fetchedrowcount, 1);
RowSetIterator deleteiter = vo.createRowSetIterator ("deleteiter");
If (fetchedrowcount > 0)
{
deleteiter.setRangeStart (0);
deleteiter.setRangeSize (fetchedrowcount);

for (int i = 0; i < fetchedrowcount; i ++)
{
Row = (ChartTemplatesVORowImpl) deleteiter.getRowAtRangeIndex (i);
System.out.println ("Inside the loop" + i);
For performance reasons, we generate ViewRowImpls for all
Objects in view. When we need to get an attribute value,
We use the accessors appointed instead of a generic string search.
Number currentTempID = row.getChartTemplateId ();
System.out.println("ChartTempId-selectedTempId"+currentTempID+"-"+selectedTempId);
If (currentTempID.CompareTo (selectedTempId) == 0)
{System.out.println ("deletion of graph model");
It performs the deletion.
Row.Remove ();
getOADBTransaction () .commit ();
System.out.println ("Deletein graph model");
break;
} / / end if

} / / end of loop

} //end if fetch County
deleteiter.closeRowSetIterator ();
} //end try
catch (Exception e) {}
e.printStackTrace ();
getOADBTransaction () .rollback ();
} / / end catch * /.
}

Kind regards

All of the suggestions above are worth. Its up to you on how you want to manage. I remember for my good days at Oracle, we used to create the EOs for same search your. Advantage: You need not update once an LMD was carried out since the EO has been already updated. However, concerning the development of product and we had to follow all the guidelines and constraints.

So this is a call, you must take on how much impact on performance (depending on the complexity of the query, no tables, cardinality of records etc.) is considered to impact for your end users. Hope that you have found the complete picture.

  • Materialized Oracle view | Deleting records, Oracle materialized view

    One question reg Materialized views.

    If as part of the interview of the Source database, we remove some (older) recordings, the materialized view will also be updated with the deletion?

    I believe that the answer is Yes. In this case make sure that deletion is not the case?

    Is there anyway that we'll stop MView update to delete records that is inserted once even if we remove the same records in the source DB?

    This is a common scenario, especially with materialized views that summarizes the detail data where you want to keep the summary but not the detail, and it is discussed in the documentation.

    The technique is to make the MV refresh on request, delete the data in the detail tables and the CONSIDER_FRESH procedure to prevent the changes propagating to the MV. You will probably find it in the docs by searching on DBMS_MView.Consider_Fresh. There are a few caveats to note, in my opinion.

  • Developer Mode error: outdated., the xxAM.xxVO1 view object contained no trace. The records displayed may have been deleted, or the current record of the view object is not properly initialized.

    Hi all

    I'm creating a Maunal search page.

    To do this, I created a view based on a custom display object.

    Page contains 2 parameters.

    If I give all settings and click the OK button.

    It gives the following error.

    Developer Mode error: outdated data


    This page contains outdated information. This error could have been caused by the use of the buttons of the browser (the browser back button, for example). If the browser navigation buttons were not used, this error may result from coding errors in the application code. Please check press the back button on the browser developer guide - view primary key object comparison section to review the main cause of this error and correct the mistakes of coding.


    Cause:
    The view BLTrinDisplayAM.ViewVO1 object did not contain any record. The records displayed may have been deleted, or the current record of the view object is not properly initialized.

    To visit, please click on the Home link at the top of the application page to return to the main menu. Next, go to this page using the app's navigation controls (menu, links and so on) rather than use the controls of the browser as rear or front.

    So if I pass all parameters and click Go, then the corresponding record is displayed.

    Why, for the first time, if I give the parameter and click Go, obsolete data error is coming?

    Please help me.

    Grateful for your help!

    You use the object of the view for the search criteria and search results fields.

    I suggest you to remove references of VO fields of search criteria, item1 and item2.

    And in the event of the button 'Go' in the processFormRequest, get the criteria for field values entered by the user as below and run the object (ViewVO1) of the view by using these values.

    String buCode = pageContext.getParameter ("item1");

    String lsiCode = pageContext.getParameter ("item2");

  • Question in cooperation with af:iterator and by program (add and delete records using the list)

    In our application, we try to add and delete records within a one: iterator lie to the backing bean list table.

    According to the feature remove should not fire any validation form so we are settign Remove button including the immediate property. And add can throw validation before adding a new record.

    Here the problem comes with button Delete with activated immeidate.  The deletions list action recording is removed from the collection list at the beacking bean, but after that the interface iterator partial page refresh user displays with bad Recordset. Some how instead of getting the last recordings of server of the user interface displays the previous local values for input components.

    For example: if I have 5 files in the list and delete record 2nd of collection. Backing bean (server side) the 2nd record is perfectly removal of list collection.

    On the user interface, the iterator 4 records are displayed as the size of the list is 4, but instead of 2nd record the last record is not rendered. According to my understanding, as deleting comme la suppression touche key is set immediately then the some how these recordings (genereted the Id of component runtime inside the i1: 0:it1 etc...) Apply request vandekerckhove is not updated gettign, Hene showing the old local values inplace of these components of entry and this behavior is only for input components.

    Can you suggest me a solution more come to the question above. Delete with immediate should unregister correspondent and only the record deleted if pannals UI.

    Help, please.

    You probably need to reset submitted values.

    For this, you can use this util class: ResetUtils (reference Java APIs for Oracle ADF Faces)

    For example: ResetUtils.reset (iteratorBinding);

    BTW, you should never bind components to bean managed with a scope greater than the scope of the request.

  • Delete record behavior does not wait for the "submit" button

    I have master / detail pages as a whole.  Of all the detail, there are links to delete or update a record.  When I click the link to delete the folder, it goes to the confirmation page with the correct record.  Now, when I add the behavior delete record server and a button "submit", it is what is happening.  As soon as I click on the link to access the Delete Confirm page, deletes the record and the page redirects to the page that I put in the server behavior.  It does not display the confirmation page and does not wait for me to hit the button confirm.  The page runs and removes the page from the database.

    How can I get to wait until I hit the submit button?

    You must surround your request deletion with an "If" statement seeking a confirmation variable, then when the user clicks the confirmation link, you can pass the necessary variable and the ID of the record that the delete request is pregnant.

    As an alternative, you can use a JS alert fuction to ask if they are sure they want to delete the folder, and then delet allwo runs after confirmation to the user. To do this, you can use code like this...


    onclick = "return ('are you SURE you want to DELETE this record? confirm")">

  • Need help with the update server behaviors and deleting records

    I am 'trying' to use the update and delete record server behaviors and I can't get the redirection page to set up correctly. What I'm trying to do, is to have the redirection came up with the right records depending on the CompId page. It seems that it is taking the CompId and agreementId (which are my unique ID) and use them in the url of the redirection page. Also, it updates the table. Here is the url that appears after I have send the update:

    http://localhost:8888/dotweb/maintenance/agreement_home.php?CompId= & agreementId = 7

    Here is the code for the update page:

    Name of the document
    Signed?
    First name
    Family name
    Date of signature

    Pending patent, trade mark, Tradesecret and straightened to copy recorded
    Copyright KML designs 2009

    Can someone tell me why it would show the CompId and agreementId when everything I asked the CompId? Thanks for your help. Just in case, I enclose you an html version of this file. It must be a php file, but is not one of the allowed file types.

    CompId is not filled in the URL because you try to use the result of the rsAgree recordset object until the result of the recordset is created. However, you pass the CompId value via array $_POST as a hidden field.

    Change this line (52):

    $updateGoTo = "agreement_home.php?CompId=" . $row_rsAgree['CompId'] . "";
    

    to do this:

    $updateGoTo = "agreement_home.php?CompId=" . $_POST['CompId'];
