How can i call my function from a procedure?

My function is:
create or replace FUNCTION test(pAttributeName IN NUMBER)
RETURN VARCHAR2 IS
ret VARCHAR2(100) := NULL;
VAR n1 NUMBER
BEGIN
SELECT Klartext INTO ret FROM piclist WHERE ATTRIBUTNAME = 'voltage_level' and PICLIST_ID =pAttributeName;
RETURN ret;
Insert into BM_ATTRIB(ID_ERFASSUNG,ID_ATTRIBNAME,ATTRIB_CHA,BM_ATTRIB_ID) VALUES(1,1,ret,1);
exception
when no_data_found then
ret := 'AAA' ------- you can return any default value,if you like
--return ret;
return NULL;
when others then
dbms_output.put_line('Exception:'||sqlerrm);
End;
I want to call it from a procedure!
Please help!
Nicole

if the function is in the same package as the procedure then merely specify the function name and parameters:
retcode := functionname(param1..paramn);
If in another package then:
retcode := packagename.functionname(param1..paramn);
If the function is in another schema then you need to grant execute rights to the package/function to the schema trying to run the function:
grant execute on packagename/functionname to otherschema;
you need to be the package/function schema owner to do the above grant.

How can we call actionscript functions from js

hi
how can we call Action script function from js file . i
tried ExternalInterface. add Callback() .but it throws an error .is
there any other chance to call action script method .thnx in
advance

angadala,
some people have found it is good to include the full
qualification path, ie
if (flash.external.ExternalInterface.available)
flash.external.ExternalInterface.addCallback("ext_method_name",int_method_name);
} // if (flash.external.ExternalInterface.available)
There are also browser differences which affect how you find
the Flex application object which are documented at

Can I call a function from a dll in LabVIEW that returns:double*string and int.?

I have a function from a dll that return a double* string and an integer. How can I call this function from LabVIEW? There is a possibility to work in LabVIEW with a double* string?

Two difficulties I can see with this.
First the application seems to allocate the array of references
internally and return a pointer to that array. In that case there must
be another function which then deallocates that array again.
Then you would need to setup the function call to have a pointer to an
int32 number for the deviceList parameter and another pointer to int32
one for the plItems parameter.
Then create another function in your DLL similar to this:
HRESULT WRAPIEnumExtractDevice(WRAPI_NDIS_DEVICE *lpDeviceList, long i,
CHAR lpszDeviceName, LONG lenDeviceName,
CHAR lpszDeviceDesc, LONG lenDeviceDesc)
if (!lpDeviceList)
return ERROR_INV_PARAMETER;
if (lpDeviceList[i].pDeviceName)
WideCharToMultiByte(CP_ACP, 0,
pDeviceList[i].pDeviceName, -1,
lpszDeviceName, lenDeviceName,
NULL, NULL);
if (lpDeviceList[i].pDeviceName)
WideCharToMultiByte(CP_ACP, 0,
pDeviceList[i].pDeviceDescription, -1,
lpszDeviceDesc, lenDeviceDesc,
NULL, NULL);
return NO_ERROR;
Pass the int32 you got from the first parameter of the previous call as
a simple int32 passed by value to this function (and make sure you don't
call this function with a higher index than (plItems - 1) returned from
the first function.

How can i call a zreport from my bsp page.

Hi friends,
How can i call a zreport from my bsp page.
Moosa

Hi Friend,
These are the codings to be wirtten in BSP for transferring values to the REPORT
DATA:wf_date TYPE ztable-ID.
      data:seltab type standard table of rsparams,
       wa_seltab like line of seltab,
     event TYPE REF TO if_htmlb_data.
DATA:p_value TYPE REF TO CL_HTMLB_INPUTFIELD.
event = cl_htmlb_manager=>get_event( runtime->server->request ).
p_requ ?= CL_HTMLB_MANAGER=>GET_DATA(
                                        request = runtime->server->request
                                        name     = 'inputField'
                                        id       = 'i1'
if p_requ is not initial.
wf_date = p_requ->value.
endif.
clear wa_seltab.
if wf_date is not initial.
wa_seltab-selname = 'P_REQU'.
wa_seltab-kind = 'P'.
wa_seltab-option = 'EQ'.
wa_seltab-low = wf_date.
append wa_seltab to seltab.
endif.
submit *ZSAMPLEAP1* with selection-table seltab AND RETURN .(ZSAMPLEAP1 refers to the report name and AND RETURN for coming back to the BSP page after the completion of its operation in Report )
IMPORT int_name TO int_name FROM MEMORY ID '*zid*'.(For importing the obtained value from Report)
In Report
REPORT ZSAMPLEAP1.
SELECT-OPTIONS: p_requ FOR ztable-id NO INTERVALS.
SELECT SINGLE name from ztable into int_name WHERE id = p_requ-low.
WRITE:int_name.
    EXPORT int_name TO MEMORY ID 'zsharmila'.

Can LabVIEW call a function from a .sys file or is LabVIEW limited to dll access?

My vendor has sent me a .sys file with functions accessing their hardware. Can i call these function from labview directly or do I have to wrapper the .sys with a dll?

Well a sys file is a kernel device driver. LabVIEW does not have any direct way of accessing such a driver. The way kernel drivers are accessed is usually through a DLL which makes calls to WinAPI functions such as CreateFile(), ReadFile(), WriteFile(), CloseHandle() and DeviceIORequest(). Since these WinAPI calls are basically just DLL calls too, you could theoretically use the Call Library Node to call them and access the kernel device driver in such a way.
However for any kernel device driver with more than one or two device driver calls, it will certainly be easier in terms of development, debugging and maintenance of the code, to write actually a dedicated DLL in C/C++ for this device driver and access that DLL from LabVIEW, especially if you consider the LabVIEW datatype limitations when designing the DLL interface (Basically this same DLL can then be called from any other Windows development environment, be it Visual Basic (similar datatype limitation as LabVIEW), Delphi, (Visual) C, LabVIEW or also various scripting environments like Python and Lua.
Some of the necessary WindAPI calls are rather involved and pose quite a bit of trouble to get the parameter data right in LabVIEw.

How can I Call the MainVI from its SubVI, and this happen recursively?

Hi All,
How can I Call the MainVI from its SubVI, and this happen recursively?
Actually, LAbView 7.1 doesn't support recurssion?
Plz help me out!

Dear GerdW,
Thanks a lot 2 all of u guys,for all the brilliant responses.
Actually, my basic aim is to call the Main VI, containing a SubVI.....
Now, I want to call my main VI from this SubVI...recursively!!!!!..but whenever I tried to put the MainVI in this SubVI..an error message pops out saying recursive calling is not possible.
I also tried using "Call by reference" but tht also didn't worked...an d error is somewat like...VI is invalid..or type matching..or state matching error.
Here, Im attaching the snapshot of the MainVI... Im calling the SUBvi from it... It is running GOOD n FINE...
But prob arrives when I call the Main from the SUBvi, which looks like same as MainVI(with little differences).
I hope, Im clear in my words n not being ambigous.
Plz, correct me where ever im wrong.
Thank You.

How do I call a function from an Itemrenderer?

Hi, Im new in flex and I wonder if I can call a function from within an AdvancedDataGridRendererProvider
for example:
<mx:AdvancedDataGrid>
 <mx:columns>
 <mx:AdvancedDataGridColumn dataField="id" />
 </mx:columns>
 <mx:rendererProviders>
 <mx:AdvancedDataGridRendererProvider
 dataField="detail"
 renderer="components.myRendererProvider"
 columnIndex="2"
 depth="2"
 />
 </mx:rendererProviders>
</mx:AdvancedDataGrid>
<mx:Script>
 <![CDATA[
 public function outerFunction(){
 ]]>
</mx:Script>
myRendererProvider
<?xml version="1.0" encoding="utf-8"?>
<mx:HBox xmlns:mx="http://www.adobe.com/2006/mxml" paddingLeft="10" paddingRight="2" horizontalGap="2" paddingTop="0">
<mx:Script>
 <![CDATA[
 public function callOuterFunction( ){
 how do I call the outerFunction() from here?
 ]]>
</mx:Script>
 <mx:LinkButton fontSize="13" fontWeight="bold" click="callOuterFunction( )" label="label" />
</mx:HBox>
thank you in advance.

There are two ways to call a function from within an ItemRenderer. One way is to dispatch an event from your ItemRenderer and listen for the event in your main application. This approach has the advantage of creating loosely coupled code which is eaiser to maintain and extend if needed, but it takes a bit more work to set things up than using the second aproach lised below. You could also create a custom event to have greater control over what data is sent with the event.
private function callOuter():void {
 this.dispatchEvent(new MouseEvent());
The other approach is to call the main application by using parentDocument.
private function callOuter():void {
 parentDocument.handleItemRenderer();

How do I call a function from another file?

In MainView.m I have one function -(void)goTell;
I want to be able to call the function from SecondView.m. How do I do this?
I have declared the function in the MainView.h and added #include MainView.h to SecondView.m, but it still doesn't work.
This code crashes my program (for some reason this board takes away my brackets... assume the code is written correctly):
[[MainView alloc] init];
MainView *myMainView;
[myMainView goTell];
By the way... goTell has nothing in it. It's just a blank function for testing purposes.
Ethan

BTW - Wrap your code like this in posts tags so it stay readable.
put code here
Your code needs to be:
MainView *myMainView = [[MainView alloc] init];
[MyMainView goTell];

How can I call a variable from another class

hi
If I have two classes : one and two
In class two I have a variable called : action
In class one I want to check what is the value of action.
How can I call action?

Thank you scorbett
what you told me worked fine, but my problem is that MyClass2 is an application by itself that I don't want to be executed.
Creating myClass2 as in the following:
MyClass2 myClass2 = new MyClass2();
[/code]
executes myClass2.
Can I prevent the exectuion of MyClass2, or is there another way to call the variable (action)?

How can i call a servlet from a servlet ?

Hello,
Can i call a Servlet from within a Servlet ?
and is it "right thing" to Do ?
Thanks

JMO, but I wouldn't do it like this.
Don't have a remote object like a servlet doing database queries for your app. That will mean TWO network hops for every query if the database resides on another machine. The network is the biggest bottleneck you've got.
Write a JavaBean that does the database stuff for you and just have the first servlet instantiate it when it needs it. A Bean has a better chance of being reused, too. Write a TableGateway or DAO for your object.
Or write an EJB to do it.
The only time I've done a servlet-to-servlet connection like that was for one servlet running in a DMZ that would authenticate a user and then forward the request to another servlet running inside the second firewall.
I wouldn't encapsulate database query logic in a servlet like that. JMO - MOD

How do I call Vee functions from TestStand ?

I wish to call Vee functions from TestStand steps.
I am using Vee 6.01 and TestStand 2.0.

Hi Gerry,
Sorry about that. Below is a sequence file created in 2.0.1f1. Please copy the contents of the zip file (previous attachment) into the folder \Examples\VEE\Using ActiveX (VEE 6.0). Please create this directory if it does not exist. The next thing you will need to do, is register the TestStand VEE server located in \Examples\VEE\Using ActiveX (VEE 6.0)\VEE_StepType.dll. To do this:
1) Select Start>>Run.
2) Type regsvr32 "C:\TestStand\Examples\VEE\Using ActiveX (VEE 6.0)\VEE_StepType.dll"
You should get a message saying that the registration was successful. You should now be able to run the example. Please let me know if you encounter any further problems. Thanks!
