Is it possible to change the nulls and numbers?

Experts-

I have xml... PRODUCT GROUP, PRODUCT, QUANTITY, PRICE columns. (QUANTITY, PRICE are numbers)

There are empty values here and there in the price, the quantity columns...
I'm my XML in the co-location model and thus have <? sum (current - group (/price))? > and <? sum (current - group (/price))? > in the report.

Because NULL values, it gives me NaN in the sum.

I need to display null (in format of detail for products) values and the corresponding sum to product group... (I tried to summarize, but its gives me NaN)

Help, please.

Thank you.

    is it possible to change the background and foreground color of the text on a simple two-color with Photoshop 6.0 jpg image?

    Yes, but given that the jpg file is flattened, you would have to make a selection of the text - the magic wand tool could work to do this, without seeing what you are working on. Then simply use fill to fill in desired fg or bg color.

  • Is it possible to change the URL of an application?

    Hi all

    I was working with oracle apex and created some applications almost a year back, due to my graduate studies, there is a discrepancy with the tool... and finally I am.

    Plan to create an application that will be similar as a personal Web site. My question here is... If it is possible to change the URL and keep a single which includes my name too

    instead of having this great...

    http://Apex.Oracle.com/pls/Apex/f?p=10221:1:116416608594529

    I understand that the entire URL described page n ° no lettering and the session but ID its my doubt possible or not... If possible then how to proceed?

    Thank you

    with respect,

    Robette.

    Thanks for the reply of Tony!

    Exactly, you got my point... that's what mean...

    I want to create a personal web application in the oracle apex and be hosted in another site with a pretty URL (say xxxxx.com... If the URL includes a part of my name which is very appreciated) so that everyone can check out my page and if needs I can include this URL in my RESUME, but I understand that for my own use. Why I'm preferring apex Oracle, I just want to remind the old concepts and practical tip that is there.

    If this is not possible in Oracle apex. Could you please suggest an idea... ?

    Once again thanks for your reply very...

    Kind regards

  • Is it possible to change the default settings of signature in EchoSign for 'first' and "Do I sign" Please?

    Hello

    I still need to sign the documents first and change the settings each time - when in a hurry, I managed to send the document without signing which is really irritating. I wonder if it is possible to change the settings so that it uses by default "That I sign" and "first"? If this isn't the case, please this feature could be added?

    Thank you very much in advance.

    Hello Char40486575,

    If you have an account level P1 (Enterprise and above), you can enable the setting by clicking on the tab accounts-> account settings-> send settings and select "Sender sign sign first then recipients" under "Default signing the order" and also check the default "sender signs a document" Yes.

    I work for a German Office and my collegaues I would use the creative suite cs4 for their projects. The original German version is quiet expensive - that's why I would like to buy an American... Unfortunately my collegaues aren't in English, so... is it possible to change the language in version cs4 design standard?

    Adobe sells more CS4.  They sell only new versions of their products.  In addition, you can not buy an American copy if your company is based in Germany.

  • [ADF, JDev12.1.3] LOV entry: is it possible to change the criteria to view / query to use before the opening of the popup?

    Hallo,

    I would like to know if it is possible to change the criteria for the view or the query used by an LOV entry before the opening of the pop-up window (on the click the icon in the search).

    Thank you

    Federico

    You can change the implicit vc used by the LOV, overwriting the popuplistener and a different VC as

    {} public void onLauchLov (LaunchPopupEvent launchPopupEvent)

    String submittedValue = (String) launchPopupEvent.getSubmittedValue ();

    run the queries only if value is submitted

    If (submittedValue! = null & submittedValue.length () > 0) {}

    RichInputListOfValues lovComp = launchPopupEvent.getComponent ((RichInputListOfValues));

    BindingContext bindingCtx = BindingContext.getCurrent ();

    BindingContainer links = bindingCtx.getCurrentBindingsEntry ();

    JUCtrlListBinding lov = bindings.get ("JobId") (JUCtrlListBinding);

    VCM ViewCriteriaManager = lov.getListIterBinding () .getViewObject () .getViewCriteriaManager ();

    ensure that the criteria of display is disabled

    vcm.removeViewCriteria (ViewCriteriaManager.IMPLICIT_VIEW_CRITERIA_NAME);

    Create a new view of the criteria of

    ViewCriteria vc = new ViewCriteria (lov.getListIterBinding () .getViewObject ());

    Use the name of the default view criteria

    '__DefaultViewCriteria__ '.

    vc.setName (ViewCriteriaManager.IMPLICIT_VIEW_CRITERIA_NAME);

    create a display for all queryable attributes criteria

    VCR ViewCriteriaRow = new ViewCriteriaRow (vc);

    for this example, I put the query filter for 60 DepartmentId.

    You can determine when running in reading to a managed bean

    or the link layer

    vcr.setAttribute ("JobId", submittedValue + "%");

    Note also that the line of view criteria consists of all attributes

    who belong to the view list LOV object, which means that you can

    filter on multiple attributes

    vc.addRow (vcr);

    lov.getListIterBinding () .getViewObject () .applyViewCriteria (vc);

    }

    }

  • Bootcamp (Win10) has not started after you changed the partition and updated at El Cap.

    I have a MacBook Pro (retina, 15 inches, end of 2013), 2 GHz Intel Core i7 with 8 GB of Ram.

    I had 2 system installed, Win 10 + Yosemite from the windows of beginning and the use of most of the time.

    Yesterday, I ran out of disk space and passed the partition in OS X with disk utility.

    While I changed the partition and I also upgraded to the El Cap.

    After all, I can't start by winning 10 more, although I could see my windows in the startup disk Control Panel.

    I checked some thread here and mess with command autour terminal, but nothing has worked for me.
