Create my own deletion links in a report

I use the instance online on apex.oracle.com.

I am trying to create links 'Remove' in a report. Here are the steps that I've taken to establish this:

1 modify the query to add a static column 'DELETE '.

2. create a hidden page P4_REM_ROWID element

3. in the attributes column, make a link to the column, the column REMOVE target: Page in this Application, Page: 4 (same page), ask: DELETE Item1: P4_REM_ROWID, value1: #ROWID # and accepting the default values for the others.

4. create a process: On Load - before header, execute processes: once a page visit. Condition type: request = Expression 1, term 1: REMOVE

With the following PL/SQL:
BEGIN
  DELETE FROM my_table WHERE rowid = :P4_REM_ROWID;
END;
When I click a delete link in the report, I will not get an error, but nothing will be deleted.

I found that it doesn't, it is because the order of the day: P4_REM_ROWID will actually have the value NULL when the code is executed.

Anyone know where this is wrong?

Sorry that I missed a bit here... because before submitting the page, you must set the value of the rowid in your page, article, so it can be used in PL/SQL

Add this javascript function to your page header

function deleteRow(pRwId) {
//set the row id value into page item before submitting
 $s('P4_REM_ROWID',pRwId);
//submit the page
 doSubmit('REMOVE');
}

Select rather target: URL > in the URL field add javascript:deleteRow('#ROWID#');

Change this by creating a process: on submit - after calculations and Validations

This should work, mark it

  • How to create my own reactive model

    Hello

    I need to create my own sensitive model, so we can accelerate the development of our e-learning modules.  I know how to create a model.  But it gives me the opportunity to make a static.  I thought that I could open the default reactive model file, modify and then save it under a new name. But it is not found or I can't find it! .

    Each active web sites I found that eLearning brothers allows you to download what they call a model, but this is a project, not a true template file (CPTL).

    Can someone help me please?

    Thank you!  Rik

    Are you sure that you need a model? A sensitive issue is not enough? Take a look at my last blog entry to see the difference. I was little confused by confusion about themes and templates, too, as you know with brothers in e-learning assets. Never, they offer a model, or a theme, but always a cptx file. Here is the link:

    What's in a theme - a model? -Captivate Blog

    There is no model of reagent by default as far as I KNOW, there are several default only reactive themes included with Captivate and also several pallets of theme colors.

  • Using a variable db link for interactive report

    I have a requirement where users select an instance a LOV apex (link db) and data in an interactive report query based on the selected db link.

    I use a db link in a report query interactive but only if I provide the exact name of the binding. If I'm doing something link select * from foo@:P12_DBLINK it does not work.

    It seems that my only option is to use something like apex_collection.create_collection_from_query and then I can build my dynamic SQL query and use a variable for the name of dblink. Then I create just a from IRR of my collection.

    This sound correct approach like that or am I missing something?

    Any suggestions are most appreciated,

    Hi John,.

    Why not create a classic report based on a function of PL/SQL returns a query.

  • Create your own for hashset add() method

    Hello
    I am creating my own method for a hashset because I am pulling in data from another class.
    I did some tests with a junit and realize that my new method addPosition() does not work. Does anyone know where the problem lies?
    or if I write my wrongly junit test cases?
    Much appreciated!

    Note: position depends on an instrument, the price, the coast and the quantity called from another class... as can be seen in the junit.
    import java.util.HashSet;
    import java.util.Set;
    import java.util.Iterator;
    
    
    
    public class Portfolio  {
         
         Set<Position> post = new HashSet<Position>();
         
         protected Position _position;
         
         
         public Portfolio( 
                   Position position                   
              ){ 
              _position=position;
              }
         
         
         public void addPosition(Position position){
          post.add(_position);
         
         } }
    The code above is false as follows junit spent.
    public class test_Portfolio extends TestCase {
         public void test1() throws Exception{
    Portfolio portfolio = new Portfolio(null);
    Set<Position> post = new HashSet<Position>();
    assertTrue(post.isEmpty());
    assertTrue(post.size()==0);
    portfolio.addPosition(new Position(new Instrument (31),new Price(new Date(), new Dollars(80)), new Side(true) , new Quantity ((long)100)));
    portfolio.addPosition(new Position(new Instrument (21),new Price(new Date(), new Dollars(80)), new Side(true) , new Quantity ((long)100)));
    
    //The following assertTrue test passed, indicating that the new entry was not added. It should be a size()==2
    assertTrue(post.size()==0);
    //The following assertTrue tests passed, which should be what the above test should show if everything is added correctly
    post.add(new Position(new Instrument (31),new Price(new Date(), new Dollars(80)), new Side(true) , new Quantity ((long)100)));
    assertTrue(post.size()==1);
    post.add(new Position(new Instrument (21),new Price(new Date(), new Dollars(80)), new Side(true) , new Quantity ((long)100)));
    assertTrue(post.size()==2);

    Does this mean that addPosition is not the link to the message?

    "Link to" means nothing in Java.

    You have an instance of your class portfolio. This object has a member variable named 'post' which is a reference to a value of Positions.

    Completely apart from that, your test method has a completely independent, independent local variable that just coincidentally happens to have the same name and type as this member variable to 'post' in the subject of your Position. If this confuses you, or if you were not aware that the two 'post' are completely foreign, then you'll want to study up on the differences between local variables and member variables. And as a proposal, you will probably need a refresher on members static vs static as well.

  • How to put links to the reports by e-mail?

    We use ibots to schedule reports, then distribute them by e-mail.
    Is there some way, we can send the links instead of reports.
    The link that we see in the browser for a specific report should be sent by electronic mail instead of report.
    Users should be able to click on the link and then provide the credentials to connect. Then only, they should be able to see the reports.
    Can anyone suggest a way to do this.

    Thank you
    Swetha

    OK, how about a total different approach?

    You said that you needed your reports to run at a time specific (you gave the example of 09:00) with the data at that time. Links must be to the 'already-run' reports, not having only not reports to run when you click the links. Yes?

    If so, then think about this. Use your iBots to run at the scheduled time and file reports on a file server. How? Read this:

    http://oraclebizint.WordPress.com/2007/12/17/Oracle-BI-EE-101332-calling-Java-scripts-and-Java-classes-from-ibots/

    Now you can use your email application to send regular emails (when reports are run) to have users access to reports on the server at a given time. You can create a javascript script for each different place depending on who needs to see that report. In this way, the when users connect to the site, they see only the reports that they are supposed to see.

  • Download the file from the link in the report

    I built a custom file upload/download capability that works very well. The UPLOADED_FILES table has 2 columns that are used to access the contents of the file - a sequence number of a related table entry and a varchar2 file type. I have a built procedure that downloads the contents of my table UPLOADED_FILES. Now, I would like to be able to display a link in my report which allows the user to download the appropriate file. I can't get the right format. I need to pass 2 variables to the procedure - a (p_file) is a column name in the report, while the other (v_type) is a static string value "SUMMARY."

    My procedure is:
    create or replace PROCEDURE download_my_file
      (p_file in number,
       v_type in varchar2) 
    AS
            v_mime  VARCHAR2(48);
            v_length  NUMBER;
            v_file_name VARCHAR2(2000);
            Lob_loc  BLOB;
    BEGIN
            SELECT UPLOAD_MIME_TYPE, upload_CONTENT, UPLOAD_NAME, DBMS_LOB.GETLENGTH(upload_content)
                    INTO v_mime,lob_loc,v_file_name,v_length
                    FROM uploaded_files
                    WHERE NOTIFICATION_SEQ_ID = p_file and
                          upload_type = v_type;
                                     owa_util.mime_header( nvl(v_mime,'application/octet'), FALSE );
     
                            htp.p('Content-length: ' || v_length);
                     htp.p('Content-Disposition:  attachment; filename="'||replace(replace(substr(v_file_name,instr(v_file_name,'/')+1),chr(10),null),chr(13),null)|| '"');
                         
                    owa_util.http_header_close;
                 
                    wpg_docload.download_file( Lob_loc );
    end download_my_file;
    I tried
    javascript:popupURL("DOWNLOAD_MY_FILE?p_file=#NOTIFICATION_SEQ_ID#&v_type='SUMMARY'");
    and I tried
    <a href="#OWNER#.DOWNLOAD_MY_FILE?p_file=#NOTIFICATION_SEQ_ID#, v_type='SUMMARY' ">Download Summary</a>
    in the URL of the link in the column to the report item. Neither work. Can someone help me fix this please?

    Hello

    Sorry, it is just spotted 'in the URL field. You should put in the Expression of HTML and remove all the settings link. The & works ok in there.

  • How do you create you own toolbars custom

    How to create your own client toolbars in the latest version of Firefox version 39. Allows you to do this and it was easy as hell to do. Now I can't find this feature anywhere. How do you do that now? Because your FAQ on it look like all FAQS in existence... absolutely useless and a complete waste of time because they never understand MY problem.

    Has more easy ways to do this.

    I don't know what is your use case and you need but a few ideas to consider.
    Bookmarks Toolbar
    No doubt, you can imagine what is available in the Customize menu.
    Button-> customize menu {(trois bar icône) {[+])-> [see her hide toolbars]}}

    You can do on this space by nesting folders instead of having unique bookmarks.
    You my put other elements including icons and the search bar.

    Menu space
    You will have items in the menu that opens. You can edit to add or remove items. Space to develop according to the needs and will become scrollable.
    Try addons
    These adddons will create additional toolbars. (I have not tried)

    This one I have not tried recently. It has more than 1/2 million users and may be exaggerated, but will certainly you can add and customize toolbars, / especially if you want the old type on the bottom status bar

    (I note that this is not a signed addon I hope that doesn't become a problem)

    It is not required for your Mac. You have already an ISO from Microsoft. The goal is for Macs where the user has a physical DVD, but the model of Mac does not have an integrated optical drive.

    BCA must ask the location of the ISO (Documents is preferable downloads) and start download the support software and start the partitioning.
