Pass a function as a parameter

Hi all,
I have a standard HTTPService call, but the following doesn't
work: <mx:HTTPService ...
request="MyClass.something.function();"></mx:HTTPService>
(says .function(); is not a variable, but I'm trying to get it to
access a public function!). MyClass.something.function() returns an
XML Object, so how can I get this to work properly? Any help would
be appreciated! Thanks!

Do that in an AS function so you can debug it.
This is probably a timing issue where MyClass is not
instantiated when the assignment happens.
Another reason to do it in a function, you can call that
fucntion on creationComplete, and be mostly assured that your
object exists.

Pass table name as a parameter to function

Is there a way to pass table name as a parameter to functions? Then update the table in the function.
Thanks a lot.

Hi, Harm,
Thank you very much for your suggestion and example. But to get my program work, i need to realise code like follows:
CREATE OR REPLACE FUNCTION delstu_func(stuno char) RETURN NUMBER AS
BEGIN
EXECUTE IMMEDIATE 'DELETE FROM student s' ||
'WHERE' || 's.student_number' || '=' || stuno;
LOOP
DBMS_OUTPUT.PUT_LINE('record deleted');
END LOOP;
END;
SELECT delstu_func('s11') FROM STUDENT;
The intention is to check if such a function can perform operations such as update, delete and insert on occurence of certain values. When executing the above statement, the system returns an error message:
ERROR at line 1:
ORA-00933: SQL command not properly ended
ORA-06512: at "SCMJD1.DELSTU_FUNC", line 3
Could you tell me where is wrong?

Passing multiple values to a parameter in report

Can anyone help me how to pass multiple parameters to a parameter in my report.
As user is able to select multiple values from list of values , can I pass the selected values to calling function.
Suppose if User selects Value1,Value2,Value3 from list of values of a parameter P_Org,
I need to pass all these values to parameter P_Org in my Before Trigger Function in Discoverer reproting tool.
Thanks in advance

I have a Before trigger Function to which the parameters will be passed.
Suppose if User selects multiple values for a parameter then how to pass these multiple Values to that parameter?
eg:In first Workbook Before Trigger is fired and the paramters for the trigger are
'par1','par2','par3' etc.
If User selects multiple values for a parameter 'par1' from the list of values displayed then how to pass all these values to 'par1' in Function?
After firing the trigger rows are inserted in a temp_table .My second Workbook will
fetch the rows inserted in this Temp Table.
I hope u understood what my requirement is...
Thanks in advance

How to pass a Class as a parameter of a method?

I have a method like below. Inside this method I need to create a variable that his type is the type of the class I have passed as a method's parameter.
For example, if I call the method like this "Meth1(ClassPerson);" insed the method I need to declare a variable of class "ClassPerson", but if I call like "Meth1(ClassCity);" I need the same variable to be declared as a ClassCity.
public function Meth1( /*I dont know what to put here*/   ):void{
     /*I dont know what to put here to declare my variable*/
     /*here
     comes
     more
     code
     using
     the
     variable*/
I tried as below but dont worked:
public function Meth1( classtype:Class):void{
     var var1:classtype = new classtype();
Can someone help me?

evyatarBH, after declare the variable like you said an error occurs when I try to access some property of the variable. I receive a mesage telling that this property dont exists.
public function Meth1( classtype:Class ):void{
     var var1:* = new ClassFactory(classe);
     //when I try to do something like the line below the error appear
     inputtext1.text = var1.fieldname;
rashare, I can't do this because I can't declare the object before the method is called. I must inform to the method only which class I will use, but the object must be created only inside the method.

Hi,
Am passing values to selection-screen fields in report RV13A004 ( used in VK11, VK12 and VK13). using below statement but material number is select-option in this report. am able to pass MATERIAL FROM using SET PARAMETER ID, can i know how to pass values MATERIAL TO range in select-options fields using SET PARAMETER Command ??

Change condition price.
call transaction 'VK12' and skip first screen.
Thanks in advance.
Regards,
Balamurugan.

Hi,
instead of using set parameters and dden call transaction use this..........
submit RV13A004 WITH SELECTION-TABLE rspar
Effect
If you specify this addition, parameters and selection criteria on the selection screen are supplied from an internal table rspar. You must specify an internal table with the row type RSPARAMS for rspar. The structured data type RSPARAMS is defined in the ABAP Dictionary and has the following components, all of which are data type CHAR:
SELNAME (length 8),
KIND (length 1),
SIGN (length 1),
OPTION (length 2),
LOW (length 45),
HIGH (length 45).
To supply parameters and selection criteria for the selection screen with specific values, the lines in the internal table rspar must contain the following values:
SELNAME must contain the name of a parameter or selection criterion for the selection screen in block capitals
KIND must contain the type of selection screen component (P for parameters, S for selection criteria)
SIGN, OPTION, LOW, and HIGH must contain the values specified for the selection table columns that have the same names as the selection criteria; in the case of parameters, the value must be specified in LOW and all other components are ignored.
If the name of a selection criterion is repeated in rspar, this defines a selection table containing several lines and passes it on to the selection criterion. If parameter names occur several times, the last value is passed on to the parameter.
The contents of the parameters or selection tables for the current program can be entered in the table by the function module RS_REFRESH_FROM_SELECTOPTIONS.
Notes
In contrast to selection tables, the data types of the components LOW and HIGH in table rspar are always of type CHAR and are converted to the type of the parameter or selection criterion during transfer, if necessary.
When entering values, you must ensure that these are entered in the internal format of the ABAP values, and not in the output format of the screen display.
Cheers
Will.

Error in passing internal table as returning parameter

Hi
Im new to ABAP OO.
I declared a parameter ret_kna1 Returning Type KNA1.
Inside the method, I am retrieving data from table KNA1 into internal table and then I want return the interal table value.
But Im not able to assing the internal table for eg : code
method READ_CUSTOMER_LIST.
data: lt_kna1 type TABLE OF kna1,
      wa_kna1 LIKE LINE OF lt_kna1.
data: lv_kunnr type kna1-kunnr,
      lv_land1 type kna1-LAND1.
SELECT * FROM kna1
INTO TABLE lt_kna1
WHERE land1 eq lv_land1.
insert LINES OF lt_kna1 INTO TABLE ret_kna1.
endmethod.
when I try to activate the error says 'ret_kna1 is not an internal table "OCCURS n" specification is missing.
but I can not declare the internal table 'ret_kna1' once again in the code, as it already defined in the parameter as type KNA1.
please help me how to assign internal table values to the returing structur.

Are you passing it as an EXPORT parameter?
use and define it in the TABLES section of your function module as so:
*" IMPORTING
*"     VALUE(INCLUDE_X_LEVELS) TYPE CHAR1 OPTIONAL
*" TABLES
*"      I_SELECTED_OU STRUCTURE HRROOTOB
*"      I_SELECTED_EE STRUCTURE OBJEC
*"      E_VIP_EPM_DISTR STRUCTURE ZHR_VIP_EPM_DISTR
*"      E_RETURN STRUCTURE BAPIRET1
That way you can pass value in the table (if needed) and then pass the table with your values based on your own logic

Passing databse functions with parameters as custom parameters from comand

Hi,
I have a database function get_id(ichar varchar2) which will return a number which I am trying to pass to a mapping as custom inout parameter using the following command:
@SQLplus_exec_template.sql RTUSER RTLOC PLSQL mapname "," "INPUT_ID=sample_pkg.get_id('I')"
and I get the following error
------ start----------
Session altered.
Role set.
override_custom_input_params(l_audit_execution_id, 'IN_FROM_DATE=1999/01/0108:00,IN_TO_DATE=2003/12/3108:00,BL_LOAD_ID=bl_job_control.get_bl_load_id('I')');

The symbol ". was inserted before "I" to continue.
------ end ----------
However, the command line with NO parameter to the function like the following command works perfect:
@SQLplus_exec_template.sql RTUSER RTLOC PLSQL mapname "," "INPUT_ID=sample_pkg.get_id"
Will OWB commandline not accept function call with parameters? Please treat this as urgent and advice ASAP.
Thanks.

Thanks, Mark. It works.However facing another issue. I try to pass to_char(sysdate\,''yyyy/mm/ddhh:mi:ss'') as one of the custom parameters to the mapping as
@SQLplus_exec_template.sql RTUSER RTLOC PLSQL mapname "," "INPUT_STDT=2002/10/2010:10:03,INPUT_enddt=to_char(sysdate\,''yyyy/mm/ddhh:mi:ss'')"
and it erros out as
------ start ------
ORA-01841: (full) year must be between -4713 and +9999, and not be 0 ORA-06512: at line 1
------ end ------
Questions:
1. Why does a simple to_char(sysdate\,'yyyy/mm/ddhh:mi:ss') as an input parameter fail?
2.what is the date format that OWB expects when we pass date as an input parameter.Can the format be modified?
OWB seems to accept the format yyyy/dd/mm only. If I pass as different format, it errors with ORA 1861 Text: literal does not match format string.
3. Where can I change the format in OWB if it can be changed.
NOTE: OWB complains only about INPUT_ENDDT and not INPUT_STDT because, if I hardcode INPUT_ENDDT like 2003/11/178:00 it works.
example:
@SQLplus_exec_template.sql RTUSER RTLOC PLSQL mapname "," INPUT_STDT=2002/10/2008:00,INPUT_ENDDT=2003/11/1706:45:59"
works fine.
Am I missing something here?
Thanks again.

Passing procedures/functions as arguments ?

I doubt this is possible but just to make sure: can a procedure or function be passed as an argument to another (or even the same) procedure or function, like in functional programming ? This would help a lot cleaning up a convoluted if-then-else spaggeti piece of code I'm dealing with.
Thanks,
George

It depends on what exactly you want to do. You can pass a function as an argument to a procedure, or another function. The called function gets the result of the parameter function as the argument. You cannot pass a procedure as an argument because a procedure cannot be resolved to a scalar value or collection.

Hello everyone
I'm using Visual Basic 6.0 and Crystal Report 9.0
I built a report using Crystal Report and named it Player_Statement.rpt. I then included it to my VB project and named it Player_Statement.Dsr
In this report I have a Parameter Field called P_Player_ID which I'm using in Record Selection Formula.
I'm using the following code to pass a value to the parameter:
Dim Report As CRAXDRT.ReportSet Report = New Player_StatementReport.ParameterFields.GetItemByName("P_Player_ID").AddCurrentValue CLng(cmbPlayerNB.BoundText)
When I execute the application I get the error message "The value or range you are adding has already existed" at the last line of code (Where I'm assigning the parameter a value)

How to passing multiple values for a parameter of discoverer(url parameters

Thanks and Regards
Venkat

Hello Venkat,
I know there are some problems with 10.1.2.0.2, maybe if you haven't done yet you can try with 10.1.2.2, assuming this version should be working for multiple parameter values :
OracleAS Discoverer 10.1.2.2 is installed with the following patch :
Patch 4960210 PLACEHOLDER BUG FOR AS/DS 10G R2 PATCH SET 2 10.1.2.2
So, once installed you can try adding your parameter as param_<parameter_name>='sfophiee,angela'
Hope this helps, otherwise feel free to log a Service Request to Support.

Passing Inner class name as parameter

Hi,
How i can pass inner class name as parameter which is used to create object of inner class in the receiving method (class.formane(className))
Hope somebody can help me.
Thanks in advance.
Prem

No, because an inner class can never have a constructor that doesn't take any arguments.
Without going through reflection, you always need an instance of the outer class to instantiate the inner class. Internally this instance is passed as a parameter to the inner class's constructor. So to create an instance of an inner class through reflection you need to get the appropriate constructor and call its newInstance method. Here's a complete example:import java.lang.reflect.Constructor;
class Outer {
    class Inner {
    public static void main(String[] args) throws Exception{
        Class c = Class.forName("Outer$Inner");
        Constructor cnstrctr = c.getDeclaredConstructor(new Class[] {Outer.class});
        Outer o = new Outer();
        Inner i = (Inner) cnstrctr.newInstance(new Object[]{o});
        System.out.println(i);
}

Passing Item Number as a Parameter takes long time,need to make it optional

Hi,
I am trying to pass Inventory Item as a parameter in the discoverer report and it is taking long time to query the results. I am not sure how to make a parameter optional (Not Required)
Please advice
Thanks,
user12048986
Edited by: user12048986 on Apr 19, 2010 2:54 PM

Hi
In order to use the value ALL in a list of values you have to do two things. These are:
1. Create the LOV like you did with a SELECT 'ALL' FROM DUAL unioned to the real LOV
2. Create a condition that looks for the word ALL
Here's the condition:
COLUMN_VALUE = :Parameter_Value OR :Parameter_Value = 'ALL'
You could also make sure the value is in uppercase using this:
COLUMN_VALUE = :Parameter_Value OR UPPER(:Parameter_Value) = 'ALL'
This way if a user keyed 'all' it would still work.
Best wishes
