Point Source Types explanation and examples

Hi all

I was confused on the different types of Source Item Type and how to use them.
I want to say I understand for PLSQL Expression or a function, I can just put for example: NVL(:P3_ITEM_NAME,'Default'), GET_SOMETHING(:P0_ITEM_ID)

But I need an example for the following types:

1 SQL query
-& gt; Select max (date) in xxx. & lt; - correct?

2 body of PL/SQL function
3 preferences
4. PL/SQL anonymous block
I tried

declare
Start
If: P9_LAST_SAVED is NOT NULL, then
: P9_WELCOME: = 'Welcome'. : P9_ALIAS: '!';
end if;
end;

does not not :)

Can someone enlighten me on this? I tried Googling it, but nothing is.

See you soon,.
Joel

Body of the PL/SQL function

declare
Start
If: P9_LAST_SAVED is NOT NULL
then
RETURN 'Welcome'. : P9_ALIAS: '!';
on the other
return "foo"; -functions must return a value
end if;
end;

Anonymous PL/SQL block

Start
If 1 = 1 then
HTP.p ('foo');
on the other
HTP.p ('bar');
end if;
end;

  • Looking for example of the Manager to OBTAIN with the PL/SQL source type

    Hello

    I currently have a Manager GET job with a running QUERY source type in ADR 3.0.  The call returns the number of records (hundreds, or even thousands of 10) in JSON and allows the user to navigate through the results.

    The call accepts several parameters that I convey just in the place where the clause of the query in the Manager.  Data is retrieved by the beach date (s).

    To prevent queries runaway with ranges for a long time, I've implemented a logic in the sql statement to limit the applicant.  The applicant requested an error thrown instead.  There are other limits that I'm imposing on other entries I need to provide useful errors for example.

    I would like to change the call GET use PL/SQL type instead of the type of REQUEST so that I can do validation on entries and send useful return error messages if necessary, however I can't find examples online.

    Are there any examples (or alternatives) would be greatly appreciated.

    Thank you

    Hello

    You can use the Pipelined functions to generate your recordset plsql and then just use a select statement of the function in the pipeline in the service definition.

  • Cloning - problems point source

    I have problems with cloning with respect to the selection of a point source. I option-click on the area that I want to clone but when I use the brush to clone it works for part of the part of beginning of the brush but clone pixels, I did not choose. For example, I'm eliminating the reflections of a flat screen TV. I'll clone of the darkest section with no reflection but shortly after I brush the brush in the clone on the reflective parts of television will start painting in something the Tablet near the center of entertainment. If instead of brushing in what I would clone I am rather the equivalent of a mouse click, it works better, but is not as smooth and I find myself with obvious circles of the brush. I know that I can adjust the opacity, but I really want to know why I'm having this problem.

    I expanded and reduced the size of the brush, when selecting the source point - always make sure that the source point includes only the area I want to clone. In my example above, I notice that if the distance between the black pixels of the screen and pixels colored tablet is 1 ", then the brush stroke when I clone the pixels used after on this same distance - about changes, give or take.

    Does this mean that it is the only way that the brushes are working and that instead of being able to make a longer stroke I need to use several shorter strokes?

    I'll clone of the darkest section with no reflection, but shortly after that I brush in the clone on the reflective parts of television the brush will begin painting in something the Tablet near the entertainment center

    That's how it is supposed to work. You choose a point source to clone of brush and then, from a different point. The brush will cover a surface brushed with some form, and this area will be filled by a zone of the same shape, cloned from the neighborhood of the point source.

    Then draw your strokes so short, that they will remain in the dark area. Clone several times, so you can use the short brush strokes, if the brush strokes are too pronounced, increase the flexibility of the clone tool.

  • Type erasure and relationship of cast.

    By shaving part of the erasure of the type of the document java tutorial (effects of Type erasure) and methods of bridge, I saw the code example below.

    public class {Node < T >

    public T data;

    public Node (data T) {this.data = data ;}

    {} public void setData (data T)

    System.out.println ("node. SetData");

    This.Data = data;

    }

    }

    SerializableAttribute public class extends < all > node MyNode {}

    public MyNode(Integer data) {super (data) ;}}

    {} public void setData (full data)

    System.out.println ("MyNode.SetData");

    super.setData (data);

    }

    }

    And follows the code below:

    MN MyNode = new MyNode (5);

    Node n = minutes; A gross type - compiler generates a warning uncontrolled

    n.setData ("Hello");

    Integer x = mn.data; Causes a ClassCastException thrown.

    The problem is that in the document tutorial he said, after the erase process of type above code like this changes.

    MN MyNode = new MyNode (5);

    Node n = min (monnoeud); A gross type - compiler generates a warning uncontrolled

    n.setData ("Hello");

    Integer x = (String) mn.data; Causes a ClassCastException thrown.

    Suddenly two typecast appears. I do not understand it. These two typecast appear in line 2 and line 4 does not appear in the class if file I open them with javap - c.

    If you open the class with javap file there is no type of plasters as above, except a single type conversion is present who tries to cast mn.data object type for the integer variable x.

    Also the class MyNode is not even a generic. Could someone please tell me why these (monnoeud) and casts (String) comes after the type erasure process, or the reason why it appears at all.

    Code changes is the equivalent that you might have written in your source code for the compiler that creates the same byte code.

    The casts of types are there to explain what object you get from the right side, so the ITI becoms apparent why this code throws a class cast exception Finally.

    But she inherits from the generic class Node and fixing his entire generic type.

  • Satellite C655 - text insert point is erratic, wandering and deletes

    I'm having an erratic text insertion point.
    When you use MS Word, WordPress or other trying to hit, the text insertion point jumps around while typing.
    The result is;

    (1) what I'm typing is inserted in the text that is already written,
    (2) text is placed elsewhere in the page, or
    (3) written text is deleted - this may be a word or a whole paragraph.
    Type it is like playing a game - type you and watch where the words are placed or erasure and always complete a sentence.

    I use a Satellite C655 which I bought through BJ, Word 7, Internet Explorer and Word Starter 2010.
    I don't like this version of Word, but my drive for Word 2003 does not install because of a "missing file" - go figure.
    It installed on my new Windows 7 desktop computer.

    Any suggestions? Is it a problem that I would return to my laptop for Toshiba?
    Since I'm a writer, this problem is serious for me.

    Hello

    If your laptop uses an older version of BIOS, please update the BIOS to the latest status.
    In addition, you must disable the touchpad while typing.
    In my case, I touched the touchpad accidentally area while typing and so my cursor jumped on another line

  • Vista will not display description of the file on mouse over. File name, Type, size, and Date modified see the upward, but no description.

    Vista will not display description of the file on mouse over. When I mouse over, a pop-up window displays showing: file name, Type, size and Date of change, however, it does not show the description of the file.

    So, for example if I have 5 files on different types of screw - the description tells me that the size of the screws. IE. 1.5 mm or 1. 8 mm.

    Update: try to get the description of the file displayed messing around in the file properties, now out of 10 records, only 2 includes the name of the file in the mice on the pop-up window. So now what lack us, it's the file name and the Description file.

  • Comparison between a static value type String and a type perhaps unrelated number

    Well I have another question of my book of text... so far I typed in exactly how they ask me to and even followed some screenshots of examples of theres. All me looks good, but of course, I'm the only one with an untrained eye.

    When I run this film I get a compiler error of: 1176 20 comparison between a static value type String and a type perhaps unrelated to line number

    Here is my code

    import flash.events.MouseEvent;

    Stop();
    var numberOfCookies:Number = 0;
    startBtn.addEventListener (MouseEvent.CLICK, getCookies);
    function getCookies(event:MouseEvent)
    {
    numberOfCookies = (Math.floor (Math.random () * (10)) + 1);
    var n: Number = 0;
    While (n < numberOfCookies)
    {
    var cookieInstance:cookieMC = new cookieMC;
    addChild (cookieInstance) .x = (Math.random () * 200) + 20, (cookieInstance) there (Math.random () * 150) = + 220;
    n ++ ;
    }
    }
    goBtn.addEventListener (MouseEvent.CLICK, checkNumberTyped);
    function checkNumberTyped(event:MouseEvent)
    {
    If (checkBox.text == numberOfCookies) //this is the line 20
    {
    gotoAndPlay (2);
    }
    on the other
    {
    gotoAndPlay (3);
    }
    }

    The error indicates well enough the problem... the compiler doesn't like to compare different types of things.  In your case, a type is a string, and the other type is a number.  If you need to force one of them to become another type, and you can go either way...

    If (checkBox.text is String (numberOfCookies))

    OR

    If ((checkBox.text) Number is numberOfCookies)

  • Satellite C855 - 2 EV - some letters do not appear when I type fast and blind

    Hi all

    I bought this Satellite C855 - 2 EV only 2 days, but I've met a few keyboard problems.
    I type blind and fast all the time, so when I noticed that whenever I type fast, a few letters only do not appear on the screen once I pressed the keys.
    Especially the SPACEBAR.

    I can only type correctly if I do it slowly and if I have pressure on each unique key. I don't want to type like this because I want to save time and just type blind and fast, I also do not want to cause more damage to the keyboard or laptop.

    Can someone help me please?
    I don't want to consider the store just because of all the hassles I have to cross.

    Thanks in advance

    I know it may seem silly now, but I think that the only solution for you is to type a little more slowly and correctly. With correctly I mean that every single button should be enabled to give a correct contact.
    Similar thing happens on my older P500. When I type faster I make so many mistakes on my word document. Some letters are missing and occasionally does not work SPACEBAR. I tap it correctly. In my view, the key, but there is no contact.

    Sorry, but I don't think you can do something about it.

    2. the J type thermocouple which came once I set TC0 + and TC - of the WSN - 212 node according to documentations, then in Labview VI, I see in the temperature value 273.56 ambiguous as - values and change them to-244.67 as once that I touch at its end. My node is set by default to the range of temp type J and Celcius, click right property tab.

    3 How long the knots will search gateway once its out of the range of gateway or I power off of the entry door? I experienced his seraches led for about 1 min then sleeps for 1 min at the start and then sleep time increases. I did this for 3-4 hours but after that 7-8 hours I couldn't see any LED flash for the search of the entry door. I needed to push button on the node, and then I start seraching.

    Kindly help me on these issues. More will come once I have will probe deeper into the system.

    Hello Orwell,

    Thanks for posting your query in Microsoft Community.

    You have a Windows 7 installation disc?

    As you cannot start your computer at all, I suggest to run a Startup Repair to repair the damaged boot system files and try to boot into normal mode. See the section: How to use Startup Repair in the following link.

    Startup Repair: frequently asked questions

    If this does not help, try to boot from a disc to install Windows 7 on the Windows recovery environment mode and then try to run the Startup Repair tool and check if you are able to start normally with mouse and keyboard.

    Hope this information is useful. Let us know if you need more help, we will be happy to help you.
