How to check the slider back row contains data or not

Hi all


How to check whether or not the cursor returned row contains data in one of its field.


Thank you and best regards,
Prakash P

Use ROWCOUNT %
Use % NOTFOUND

example of

DECLARE

   id    number;
   desc varchar2(10);
   CURSOR cursor_one IS
      SELECT
          id, desc
      FROM
          table;
BEGIN
   OPEN cursor_one;
   LOOP
      FETCH cursor_one INTO id, desc;
      EXIT WHEN cursor_one%ROWCOUNT > 20 OR cursor_one%NOTFOUND;
   ...
   END LOOP;
   CLOSE cursor_one;
END;

    If you receive the null pointer exception to

    XxafpEepStageRebateHdrVOImpl vo = (XxafpEepStageRebateHdrVOImpl) am.findViewObject ("XxafpEepStageRebateHdrVO1");

    This means that you not give the good instance of vo. Do something please post your VO.xml and AM.xml files.

  • How to check the page dirty with default values existing in viewObject?

    Hi all

    I use JDeveloper 11.1.1.4.

    I have two pages in my application. I am browsing for page2 page1.

    Before opening page 2 I created new line page 2 notice of object using method 'Create Insert()' with some default values by using the ViewRowImpl class.

    My problem is that I have a button to return to Page 2. If I click the back button, then check the Application module is dirty or not.

    But it always shows AM is dirty due to I'm setting some default values in ViewRowImpl. If I avoid the default values in ViewRowImpl then AM dirty check works fine.

    My Question is how to check the AM (or) dirty Page with default values in the object view?

    My bean Codes:

    Links DCBindingContainer = (DCBindingContainer) BindingContext.getCurrent () .getCurrentBindingsEntry ();

    DataControl dc = bindings.findDataControl("AppModuleDataControl");

    ApplicationModuleImpl am = ((ApplicationModuleImpl) dc.getDataProvider ());

    If (am.getDBTransaction (.isDirty (()))

    {

    return "Page is dirty."

    }

    My Jspx Codes:

    < af:commandLink id = "cl6" text = '2 '.
    shortDesc = "Add Row in Page2"
    actionListener = "#{bindings." Action CreateInsert.execute}' = 'Edit' >

    Thank you

  • Satellite A200 - how to check the temperature of the processor fan?

    Hi all

I suspect the fan and pulled out the fan cleaned and tested the fan on a PSU, worked out well. He put it back together, ran startup repair and now the computer is operating normally. The fan is however not appear to come at all. In the Device Manager it tells me it works very well. I'm all good with the mechanical side of the House, but I'm a quamby operating system! How to check the temp CPU or fan?

    Thought that replace the fan but don't want to go that far just to get no results. Currently using the vacuum on low like an external fan and didn't want to just run the laptop with no cooling for fear of permanent damage. Although children watch movies with her on their doona may have already reached this!

    Any advice would be appreciated.

    In addition if the fan doesn't work anymore it of necessary to replace. You can order spare parts at an authorized service provider.

  • How to save the slide show settings so when I press on Ctrl + enter only what I want?

    How to save the slide show settings so when I press on Ctrl + enter only what I want?

    huh?

    R

    I tested what you gave me there Rob. On my Mac, I have two monitors:

    -Blacken / display slide show on a monitor (the primary monitor, if I move LR in my secondary follow-up, the slide show is still on the first, but the second still works normal with LR just sitting there).

    -If I turn off slide durration I manually advance the slides with the right arrow.

    -I don't have 'Lightroom' (or with my settings current all) text on the screen.

    -Does not repeat itself.

    My Windows machine is not two monitors, but the others work properly...

    In other words, until I thought about it differently. As we seek to change the slideshow settings, I was naturally in the slideshow module. But I then remembered that the interest of the Impromtu Slideshow is that you can view the slide show playback from any module. Once I went back to the library and click Command / Ctrl + Enter, then I saw exactly what you're talking about. Both monitors are blackened, duration of the slide is ignored, etc.

    You know why? As the Impromptu slideshow uses one of the models outside the slideshow Module. Which one? Well, by default +, of course. How do change you that? Right-click (Cmde) slideshow model you prefer to use and select «Use for Impromptu slide show»

    You know, in your code curr_rec is not slider.
    You cannot use curr_rec % rowcount
    If you want to get the number of lines of your loop, then use an additional variable

    Try this please

    declare
     countLoop NUMBER :=0;
    begin
      for curr_rec in( select * from dual)
      loop
        countloop := countloop + 1;
    
      end loop;
      dbms_output.put_line(countloop);
    end;
    

    or

    DECLARE
            CURSOR csr_org IS
                  SELECT empno, ename FROM   emp;
                  num_total_rows NUMBER;
          BEGIN
                  FOR idx IN csr_org LOOP
                      dbms_output.put_line(idx.empno||' '||idx.ename);
                      num_total_rows := csr_org%ROWCOUNT;
                  END LOOP;
                  IF num_total_rows > 0 THEN
                    dbms_output.new_line;
                    dbms_output.put_line('Total Organizations = '||to_char(num_total_rows));
                  END IF;

    No need to create separate connection pool...
    But make sure that if your physical layer is built with a database... then have a pool of connections, just that since your RPD vouscopiezetcollezle in model...

    Do I have to give informed as RPD name name in the xml model.

    That's your wish, you can give a name to the template xml document can be identical to the RPD or not... This is not the question... but you must give the name of the created model...

    Also check the positions of the columns in the answers, if they even or not in the model.
