Call function pipeline with entry as a record of cursor type parameter

Hello

I want result set of query curosr to function in pipeline and then proceed to Ref cusror for java application. I wrote the code below:

CREATE OR REPLACE PACKAGE emp_pkg IS
TYPE t_emp_rec IS RECORD(empid varchar2(5),last_name varchar2(25),email varchar2(25));
     
     type obj_t_emp_rec is table of t_emp_rec;

     CURSOR get_emp_data_cur(empid IN employee.employee_id%type)
     IS
          SELECT     EMPLOYEE_ID,LAST_NAME,EMAIL
          FROM     employee
          WHERE     employee_id=empid;

          --Rowtype for table
          TYPE t_emp IS TABLE OF get_emp_data_cur%ROWTYPE INDEX BY PLS_INTEGER;

          --Object for the table type created
          get_emp_rec t_emp;

     PROCEDURE Populate_emp_details(empid     IN     employee.employee_id%type,get_emp_rec     OUT     t_emp, result out sys_refcursor);
     
     function type_out(get_emp_rec in t_emp) return obj_t_emp_rec pipelined;

END emp_pkg;
/

CREATE OR REPLACE PACKAGE BODY emp_pkg AS

PROCEDURE Populate_emp_details(empid     IN     employee.employee_id%type,get_emp_rec     OUT     t_emp,result out sys_refcursor)
IS

BEGIN

     SELECT     EMPLOYEE_ID,LAST_NAME,EMAIL
     BULK COLLECT
     INTO     get_emp_rec
     FROM     employee
     WHERE     employee_id=empid;     

     open result for SELECT * FROM TABLE (type_out(get_emp_rec));     

EXCEPTION
     when no_data_found then
          dbms_output.put_line('Invalid booking number entered');

END Populate_emp_details;

function type_out(get_emp_rec in t_emp) return obj_t_emp_rec pipelined
as
currec     t_emp_rec;
begin
          for i in 1..get_emp_rec.count loop
                    pipe row(currec);
                    dbms_output.put_line('row count of rec -'|| get_emp_rec.count);
          end loop;
end;

END emp_pkg;
/

It gives me compilation error when you call the function pipeline (type_out (get_emp_rec)). Is it wrong to call pipelined function or please correct where I'm wrong.

Help, please.

Thank you

How to call a form with splashing around by clicking on a record with a time where
Hi all

How to call a form with splashing around by clicking on a record with a time where clause. I mean when I dip, click current record I want to call another form with the details of the
record with onetime where clause. Can someone help me in this regard.

Now, I'll call you a form with parameter with where Jadi but this should be avoided.

Thanks in advance

How to call a function plugin with command line parameters

I wrote a plugin that processes an open document. The treatment can be started by selecting a menu item in Acrobat. To start the processing of the command line, I also wrote a small Visual Basic executable file that currently a bit activates the menu command. However, I now have to pass some parameters to the plugin. I managed to call a function plugin with settings by loading the .api as a library file in the VB executable. But it seems that the entire Acrobat SDK functionality is not initialized in this way. So I can't work with the PDF file. How can I call my function plugin with settings in Acrobat? Thomas

You must establish a form of IAC (communication monitor) of your VB application with your plugin.

Whether COM, DDE, IPC, named pipes, shared memory files share, etc. is to you...

How to call a stored procedure with a REF CURSOR output parameter

I'm looking forward to example calling a function/stored procedure with a REF CURSOR output parameter and get the result.
In other words, I have a stored function/procedure that runs a SELECT statement using the OCI library and then he could get the values of each row and each column.

I put a code snippet, it have only the main thing to call a simple stored procedure and to print the name of each column of the cursor, but I couldn t to print out values in the table that calls the stored procedure.
I understand that the next step is to call an OCIStmtFetch.
How to associate the slider with the OCIStmtFetch?

If you need more information, just tell me.

I use ANSI C with HP - UX (HP - UX C) operating system and Oracle 10 g.

Kind regards.

Hi Antonio,.

I see this:

c_buf=(ub1 **)calloc(sizeof(ub1 *),3);

...

rc=OCIDefineByPos(pOciStatCursor,&pdef,(OCIError *)pOciError,pos,c_buf[pos-1],size+1,(ub2)type,(dvoid *)c_indp[pos-1],(ub2 *)0,(ub2 *)0,OCI_DEFAULT);

That I don't understand. You allocate space for 3 pointers ub1 but I don't see where these pointers are then initialized to point to where the data is to be stored.

I do not read correctly?

Sorry for posting code long, but here is an example of code that I have. It is much more 'code' for your code, but maybe that will be enough...

NOTE: This is just the code example and not rigorous. For example, I don't check the memory, allocations etc in this code!

Kind regards

Activation of calling function WhatsApp

So I was wondering if anyone of you guys have the calling function enabled on whatsapp and if could you please call me to activate it? Then PM me and I will reply with my number, I'm not posting here cos I don't want the world to see that it

So I finally managed to get calls on WhatsApp! I had to uninstall the version of WhatsApp page and install one of the playstore. If you do that and you receive a call (or if you have received a call) the feature must be activated

Unexpected behavior first LV call function called VI.

Hello

I call a VI that has the first call internal ventricular function. It works as expected when I run the sequence of the first time. However, when I run the sequence for the second time, First Call function returns 'false', when I run this VI for the first time. Expected value is 'true '.

Why?

I use the default options for loading and unloading. I played with the options of unloading in the property Options running, but futile.

What should I do to make it work because I expect?

Stuck to calling function c ++ QML

Hello

I am a newbie in QML. While playing with examples, I tried calling function c ++ QML.

hand. QML is-
```
import bb.cascades 1.0

Page {
    Container {
        layout: StackLayout {
        }
        Label {
            text:  _foo.sayHello();
        }
    }
}
```
c ++ is
```
//say Hello
QString foo::sayHello()
{
    QString hello = "Hello!";
    return hello;
}
```
But my program does not say hello. What's wrong?

Could you show the function declaration and the way in which the class is exported to QML?
The function must be declared as Q_INVOKABLE.

Check the logs of apparatus for run time errors may also give a clue.

Call function scene MC

Question: How can I call function of MC in the first image of the stadium?

Example:
First MC: ToggleButton have the function:
function setSelected (b)
{
selected = b;
If (selected)
_this.gotoAndStop ("DN");
on the other
_this.gotoAndStop ("up");
}
This code working fine inside MC...
This place of button on the stage with the instance name: btn_mc
When I write Action in the first image of the stage: this.btn_mc.setSelected (true) in the output window of the browser, I got an error message: setSelected is not a function.

You must declare the function to make it accessible. Try this inside the movieclip:

setSelected var = setSelected;

function setSelected (b)

{

selected = b;

If (selected)

_this.gotoAndStop ("DN");

on the other

_this.gotoAndStop ("up");

}

Then, it should work out the movieclip:

This. ToggleButton.setSelected (true);

MuseSJAssert: error calling function selector: TypeError: object does not support this property or method

I get this error message with IE, version 8 upwards. The message appears once you navigate to another page on the site and then return to the home page. Can anyone offer advice on how to solve it? As the cursor on the site doesn't seem to work with IE, we wonder if that's where the whole issue.

Thanks in advance.

Hi Martin,

Could you please try some steps here.

Cannot call function AS3 from JavaScript

Hello
I am trying to call a function in ActionScript 3 with JavaScript. The problem that I can't get one of the browsers to trigger this AS3 function. Debuggers to say that the function is not defined when I call on the flash object.
What is supposed to happen is - the javascript function calls the AS3 function and passes an integer value. This integer is then used to remove one of the 20 funds sovereigns and load that into the flash movie.
Please let me know if you can think of everything I can do to make it work! I've been blocked for hours and can't seem to get there.
Here are my actionScript:
import flash.net.URLRequest;
import flash.display.Loader;
to import flash.external.ExternalInterface;
var movies: Array = ["idle - ok.swf ',"idle - good .swf"];
First, it loads it "Hello swf»
var helloLoader:Loader = new Loader();
var helloURL:URLRequest = new URLRequest ("idleAvatar.swf");
helloLoader.load (helloURL);
addChild (helloLoader);
var setAvatar:Function = loadAvatar;
ExternalInterface.addCallback("IsStatic",IsStatic) ("callSetAvatar", setAvatar);
Then, this function must be called by JavaScript to load one of the other sovereign wealth funds.
function loadAvatar(indx:Number) {}
var url: URLRequest = new URLRequest(movies[0]);
var ldr:Loader = new Loader();
LDR. Load (URL);
addChild (ldr);
}
Here's my JavaScript:
"<script type="text/javascript"> ".
function callExternalInterface (val) {}
document.getElementById("loader").callSetValue (val);
}
< /script >
Here is my embed code:
<div >
"" " <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="250" height="350" id="charger" name="loader"> .
" <param name="movie" value="loader.swf"/ >
" <param name="allowscriptaccess" value="always"/ >

" <a href="http://www.adobe.com/go/getflashplayer_fr"> ".
" <img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash player"/ >
</a>

< /object >
</div>
"<a href="#" onClick="callExternalInterface (1)' >click ON < /a > ""

You don't appear to be calling any function in your actionscript code. Names between and inside are in disagreement.

document.getElementById("loader").callSetValue (val);

must call a function identified by the string "callSetValue" in your actionscript code, but you only have an identified with "callSetAvatar" and the function associated with the one on your side AS3 is specified as setAvatar...

ExternalInterface.addCallback("IsStatic",IsStatic) ("callSetAvatar", setAvatar);

but you do not have a function named setAvatar, you have a named loadAvatar

Here is a link to a tutorial that can help you see how the functions are specified between actionscript and javascript using the ExternalInterface class. He becomes confused, I suggest that you copy the code into a word processing file, so you can put clear where they have the same language between them.

procedure call function

Hi all
I have a bunch that I'm trying to call a function of my procedure and I get null in my results.
If I run the function only parameter passing works very well.
It is an example of code:

create or replace package demo as
  TYPE v_GetResultSet is REF CURSOR;
  TYPE CUSTOM_REF_CURSOR IS REF CURSOR;
  function get_region(my_id in Number)  return GetResultSet;
  procedure get_country(p_id in Number, v_cursor IN OUT CUSTOM_REF_CURSOR) ;
end;
/ 
 
create or replace package body demo as
 function get_region(my_id) return v_GetResultSet is
    v_cursor v_GetResultSet;
  begin
    open v_cursor for
    select region_id, region_name
    from countries
    where country_id = my_id;
     return v_cursor;
  EXCEPTION
   WHEN OTHERS THEN
     raise_application_error(-20001,'An error was encountered - '||SQLCODE||' -ERROR- '||SQLERRM);
  end;

  procedure get_country(p_id in Number, v_cursor IN OUT CUSTOM_REF_CURSOR) as
  begin
    open v_cursor for
    select country_name,
    case region_id when 3 then get_region(3) end;
    from countries
    where country_id = p_id;
  EXCEPTION
   WHEN OTHERS THEN
     raise_application_error(-20001,'An error was encountered - '||SQLCODE||' -ERROR- '||SQLERRM);
  end;
end;

get_region give me a line with multiple values.
Any ideas?
Thank you

}

Application.application appeal should work if the method you want to call is public.

There is also another way to do it: with a callback function.

In your pop-up:
```
private var _callbackFunction:Function;

public function set callbackFunction( value:Function ):void {
     _callbackFunction = value;
}

protected function buttonClickedInpopup():void {
     _callbackFunction(null);
}
```
And in your Main.mxml:
```
var titleWindowInstance:Popup = Popup(PopUpManager.createPopUp(this, Popup, true));
titleWindowInstance.rowData =  arr.getItemAt(event.rowIndex);
titleWindowInstance.callbackFunction = functInMain;
PopUpManager.centerPopUp(titleWindowInstance);
```

but I'm having a problem with a kind of SEO...?
Hello!
Try changing
```
