Calling a Function inside a procedure

Can you call a function inside a procedure?...if so....how?

Not all built-in functions can be used directly in an assignment.

Call a function inside a package from a stored procedure

Hello:
I am kind of new to the stored procedure. Does anyone know how to call a function inside a package from another stored procedure?
I have a existing function (func_b) inside a package (pack_a) and it returns a cursor. I want to call this function from a stored procedure (proc_c) so that I use the data inside the cursor.
can I do the following in proc_c:
my_cursor1 SYS_REFCURSOR;
begin
my_cursor1 := exec pack_a.func_b
end
It will be very helpful if anyone can point me to any reading or example. Thank you very much for your information.

guys:
Thank you for your information so far. I need some more help here. I was able to run the function in my stored procedure. However, I was not able to print the result on the screen to view the cursor result, although I am using dbms_output.put_line statement inside my stored procedure.
I use the following statement to execute my stored procedure on sql*plus. I can tell the stored procedure is executed successfully, but I did see anything printed:
DECLARE TEMP VARCHAR2(100);
BEGIN PROC_LAWS_CAD_NAME_SEARCH('LPD', 'TEST DEVICE ID', 'TEST LAST NAME', 'TEST FIRST NAME', 'F', '11112009', TEMP); END;
I tried to use 'set serveroutput on' and got the following error:
ERROR:
ORA-06502: PL/SQL: numeric or value error: host bind array too small
ORA-06512: at line 1
I am kind of confused now. thank you for your help.

Calling a function inside a symbol?

Hi there,
I'm one of those flash-devs that are trying to get Edge Animate to do what I usually do in Flash, so I might be doing this the wrong way, but I've got a symbol with a function "inside" on my stage, and I wanna call that function from the stage.
I've been trying to use sym.getComposition().getStage().getSymbol("symbolName").functionName(); but it doesn't work.
I don't have any problems manipulating the symbol itself by calling .play() or .hide() so I know the path works....can anyone show me the right syntax to call a function inside a symbol?
Thx in advance

Hi Abnesher,
An important principle to grasp is that symbols (and the stage is one of them) lies in parallel, despite the fact of instances of different symbols being nested one in another (and all in fine nested in the stage).
The consequence is that from inside your nested symbol you have no direct visibility of the function defined inside the stage symbol !
Inside the Stage symbol, in the document.compositionReady event handler :
sym.yourGlobalFunction = function( firstParameter)
// your stuff
Inside another symbol, in one of its events handlers :
sym.getComposition().getStage().yourGlobalFunction( 5);

Call library function inside a conditional disable bug

i'm trying to call a function in a dll using the call library function inside a conditional disable structure.
one of the parameters is a pointer to a C structure.
here is the prototype:
short in myfunction(short in DevNum, void *pMetrics);
outside of the conditional disable, LabVIEW allows me to wire the pMetrics parameter to a cluster.
if i put the function inside the conditional disable, LabVIEW doesn't allow me to wire it.
as a workaround, i put the cluster inside the conditional disable as well.
any ideas?

Simply create a constant of the cluster and and put it outside the disable structure. Wire this constant to all inputs (left side terminal) of the Call Library Node. A Call Library Node (CLN) set to Adapt to Type does need a valid datatype to adapt too. This works from the outside side (right side terminal) of the CLN only if the according indicator is inside the same data structure. In older LabVIEW versions you actually had to always define the left side by wiring a constant or a dummy control to it.
This has to do with the algorithme that evaluates datatypes along wires. Making that algorithme go backwards (against the natural dataflow) inside one subdiagram without causing circular references or similar is already a challange. Doing that across diagram boundaries (case, disable, loop, etc. structures) is basically impossible without causing the entire edit operation to get very slow.

Executing function inside a procedure

I have a function like fun_a(a varchar) which returns a number
I execute the function in sql prompt by select fun_a('hello') from dual;
Now i have to execute that function inside a procedure and return the output of the function to a variable like the following
create or replace procedure x is
a number;
vsql varchar2(255);
i varchar2(40):='hello';
begin
vsql :='select fun_a('||i||') from dual';
execute immediate VSQL INTO a;
dbms_output.put_line(a);
end;
I am not getting the output . Please help me in this

Or even:
CREATE OR REPLACE PROCEDURE x
IS
vsql VARCHAR2(255);
i     VARCHAR2(40) := 'EMP';
i1    VARCHAR2(40) := 'EMPNO';
a     NUMBER := primary_check_fun(i, i1);
BEGIN
dbms_output.put_line(a);
END;or just for fun,
CREATE OR REPLACE PROCEDURE x
IS
vsql VARCHAR2(255);
i     VARCHAR2(40) := 'EMP';
i1    VARCHAR2(40) := 'EMPNO';
BEGIN
dbms_output.put_line(primary_check_fun(i, i1));
END;
Well if we're going to extremes Will we could look at it and say that the parameters are pre-defined and just have...
exec dbms_output.put_line(primary_check_fun('EMP','EMPNO'));

Problem calling function inside a procedure

I have a procedure that simply calls a function, but I'm not sure how to declare it.
When I run my script oracle returns an error:
CREATE OR REPLACE PROCEDURE pr_entrada_close(
     var_id_entrada int)
AS
BEGIN
     fn_criaJobAnalise(var_id_entrada);
END;
ERROR at line 5: PL/SQL: Statement ignored3. AS
4. BEGIN
5.      fn_criaJobAnalise(var_id_entrada);
6. END;

As far as I know, that structure worked in at least 8.0 and possibly earlier. I actually saw something similar in production code on that version of Oracle. The actual function took several parameters, and using those paramters did a series of statements along the lines of:
BEGIN
   SELECT 1 INTO l_var
   FROM table1
   WHERE <predicates>
EXCEPTION
   WHEN NO_DATA_FOUND THEN
      RAISE APPLICATION_ERROR (-20001, 'Error');
   WHEN TOO_MANY_ROWS THEN
      RAISE APPLICATION_ERROR (-20002, 'Error');
END;
BEGIN
   SELECT 1 INTO l_var
   FROM table2
   WHERE <predicates>
EXCEPTION
   WHEN NO_DATA_FOUND THEN
      RAISE APPLICATION_ERROR (-20003, 'Error');
   WHEN TOO_MANY_ROWS THEN
      RAISE APPLICATION_ERROR (-20004, 'Error');
END;
-- About 4 or 5 more tables checked
RETURN 1;and the caller looked kind of like:
DECLARE
   NO_ROWS_TABLE1 EXCEPTION;
   DUP_ROWS_TABLE1 EXCEPTION;
   NO_ROWS_TABLE2 EXCEPTION;
   DUP_ROWS_TABLE2 EXCEPTION;
   PRAGMA EXCEPTION_INIT (NO_ROWS_TABLE1, -20001);
   PRAGMA EXCEPTION_INIT (DUP_ROWS_TABLE1, -20002);
   PRAGMA EXCEPTION_INIT (NO_ROWS_TABLE2, -20003);
   PRAGMA EXCEPTION_INIT (DUP_ROWS_TABLE2, -20004);
   l_v NUMBER;
BEGIN
   BEGIN
      l_v := test_tables(<parameters>);
   EXCEPTION
      WHEN NO_ROWS_TABLE1 THEN
         <do something about it>
      WHEN DUP_ROWS_TABLE1 THEN
         <do something about it>
      WHEN NO_ROWS_TABLE2 THEN
         <do something about it>
      WHEN DUP_ROWS_TABLE2 THEN
         <do something about it>
   END;
   <Continue normal processing>
END;and, yes, <Continue normal processing> occasionally failed for mysterious reasons when more than one of the checks would have failed had the function got to them, and l_v was never ever used.
This was one of the clevererbits of code in that app.

Calling a function inside an iFrame

I have a app I'm building that plays videos through an iFrame (src is our server). I want to have buttons in my client that when clicked can call functions inside the iFrame (e.g. play, pause). Obviously the problem is with doing this is browser security will not allow it. I understand AIR provides extra parameters for an iFrame to achieve this. I have been reading up on this and seen to get the impression that calling functions in the iFrame can only be done before the page loads?
Has anyone any basic examples of how I could achieve this?

How to call a function inside a class?

Hello, i am trying to fire a function onPress .. this
function is inside a class.
In this function i refer to another function inside the calss
to call a Tween. It never arrives in the second function.
I tried to make an example.
In the fla file i have:
var test:makeMovie = new makeMovie(this);
You will see a red squere and you can press on it. It should
run the tween class. Am i using the delegate class wrong?

I always have to use test movie and trace a couple of times
each time I start to use Delegate.
It wraps function.apply I think, which I tend to use more
often.
try using:
Container.onPress = Delegate.create(this,setAlpha);
and then just
setTween()
inside your setAlpha....
That's conceptually how I think I would try it above if I was
doing something similar.
I'm not sure it would have the desired effect even if the
delegate was executed as you have it coded. Unless you want
setTween's execution scope to be the Container clip in which case
you might need to do what kglad said and change the Container
reference to 'this'.
The way you have it at the moment inside setAlpha the
Delegate.create is simply creating a function...and not excuting
it.
its like : function something(){trace('what')}
and not like : something();
Below is some quick code that helps show how things work.
Notice that I assigned the delegate function to mainFunc....so that
along with the last example might provide a clue. Just paste it on
a frame and take a look at what's happening.

Dynamically call different functions inside a function

Hi there,
I was wondering if it is possible to dynamically define the function that you want to call. Almost like passing the function name that i want to call as a parameter.
I am calling a function, but do not want to hardcode the function I am calling. I have different functions that all return a boolean value, and i want to call all of them at different times through the same procedure/function.
Is this possible???
Thank you in advance!
Tanja

Or combine your functions to use function overloading, then you can use the same name...

package
     import flash.display.MovieClip;
     public class ThumbGridMain extends MovieClip
          private var grid:CreateGrid;
          public function ThumbGridMain():void
               grid = new CreateGrid();
          public function testFunc():void
               trace("testFunc was called");

     public class CreateGrid extends MovieClip
          public function CreateGrid():void
               parent.testFunc();

kglad,
Although I agree that utilizing events the way you attempted in your suggestion is better for at least a reason of eliminating dependency on parent, still you code doesn't not accomplish what Brian needs.
Merely adding event listener to grid instance does nothing - there is no mechanism in the code that invokes callTGMFunction - thus event will not be dispatched. So, either callTGMFunction should be called on the instance (why use events - not direct call - in this case?), or grid instance needs to dispatch this event based on some internal logic ofCreateGrid AFTER it is instantiated - perhaps when it is either added to stage or added to display list via Event.ADDED. Without such a mechanism, how is it a superior correct way OOP?
Also, in your code in ThumbGridMain class testFunc is missing parameter that it expects - Event.
Am I missing something?
I guess the code may be (it still looks more cumbersome and less elegant than direct function call):
package
     import flash.display.MovieClip;
     import flash.events.Event;
     public class ThumbGridMain extends MovieClip
         private var grid:CreateGrid;
         public function ThumbGridMain():void
             grid = new CreateGrid();
             grid.addEventListener("callTGMFunction", testFunc);
             addChild(grid);
        // to call a CreateGrid function named cgFunction()
         public function callCG(){
             grid.cgFunction();
         public function testFunc(e:Event):void
             trace("testFunc was called");
package
     import flash.display.MovieClip;
     import flash.events.Event;
     import flash.events.Event;
     public class CreateGrid extends MovieClip
         public function CreateGrid():void
             if (stage) init();
             else addEventListener(Event.ADDED, callTGMFunction);
         // to call a TGM function
         public function callTGMFunction(e:Event = null):void
           // I forgot this one
            removeEventListener(Event.ADDED, callTGMFunction);
            this.dispatchEvent(new Event("callTGMFunction"));
        public function cgFunction(){
             trace("cg function called");
I think this is a case of personal preference.
With that said, it is definitely better if instance doesn't rely on the object it is instnatiated by - so, in this case, either parent should listen to event or call a function directly.

1-number of argrments in function[b] TEST_DAY_NUMBER
?? and so ..!
