How call function with objects

How can i simply call a function ?
I have the structure :
A_OBJECT_TYPE with FUNCTION A_FUNC
B_OBJECT_TYPE with FUNCTION B_FUNC
C_OBJECT_TYPE with FUNCTION C_FUNC
An i need to call the B_FUNC from A_FUNC and call the C_FUNC from B_FUNC.
Actually i do a hard SELECT A.B_FUNC() INTO temp FROM A_TABLE A, B_TABLE B
WHERE A.PK = SELF.PK AND ... AND ...
Help me please

select find_id (p_id,VARR_VARCHAR('1','2','3'),e_varr_varchar('1','2','3')) from dual;

How to call procedure with Object types in java

Hi,
We have procedure declaration as follows
===============
TYPE TEST_TYPE AS OBJECT (NAME VARCHAR2(10));
TYPE TESTTYPE1 AS object (student1 TESTTYPE,student2 TESTTYPE,student3 TESTTYPE);
TYPE rect AS OBJECT
-- The type has 3 attributes.
length NUMBER,
width NUMBER,
area NUMBER,
-- Define a constructor that has only 2 parameters.
CONSTRUCTOR FUNCTION rect(length NUMBER, width NUMBER)
RETURN SELF AS RESULT
PROCEDURE G(obj1 in TESTTYPE1,obj2 out rect) as
n1 testtype;
n2 testtype;
n3 testtype;
n4 testtype;
begin
obj2 := NEW rect(10,20,200);
n1 := obj1.student1;
n2 := obj1.student2;
n3 := obj1.student3;
obj2.length :=20;
end;
=====================================================
I am not able to call the procedure in java code as I cannot figure out which out parameter type will it be registered using registeroutparameter. using cursor or struct type fails.
please let me know how I can pass values from stored procedure with objects to java.

I'm not sure what you're trying to accomplish with your procedure, but in general, this is an example of how you could use oracle.sql.STRUCT.
First, prepare your java.sql.CallableStatement using java.sql.CallableStatement cStmt = java.sql.Connection.prepareCall({ call G(?, ?) });
Note that you don't have to use the OracleCallableStatement. The java.sql.CallableStatement will work just fine.
For the IN parameter, you need to create three TEST_TYPE objects. Then you need to create one TESTTYPE1 object.
These will all be instances of oracle.sql.STRUCT.
To create a oracle.sql.STRUCT object you need a descriptor and a set of attributes. For example, to create a TEST_TYPE object you would do the following
1. StructDescriptor sd = StructDescriptor.createDescriptor("TEST_TYPE", java.sql.Connection).
2. Add a VARCHAR2 attribute to an array of attributes (e.g. Object[] attributes = new Object[]{"Student Name"})
3. oracle.sql.STRUCT struct = new oracle.sql.STRUCT(sd, java.sql.Connection, attributes)
Then do something similar to create the TESTTYPE1 object, except that the attribute array will contain three instances of TEST_TYPE struct objects.
To bind the IN parameter you need to use the java.sql.CallableStatement.setObject(1, <Instance of TESTTYPE1 object>).
To register the OUT parameter, you need to call java.sql.CallableStatement.registerOutParameter(2, oracle.jdbc.OracleTypes.STRUCT, "RECT").
Then, execute your procedure using cStmt.execute();
Retrieve your OUT parameter using oracle.sql.STRUCT struct = (oracle.sql.STRUCT)cStmt.getObject(2).
Once you've done that, to get the values of the attributes of all of your STRUCT objects, you need their descriptors and their metadata.

Call function with arguments in AS3

Hello!
I`m a new in Flex developing, and cannot understand same code
convention, im Java programmer.
How I can write correct function call in ActionScript, my
call: var goodsWnd:CreateGoodsWindow =
PopUpManager.createPopUp(this,
CreateGoodsWindow, true) as CreateGoodsWindow;
I wish call function above with argument, how I do that?
Where my class: public class CreateGoodsWindow extends
extends TitleWindow
public CreateGoodsWindow(data:Object)
}

Use PopUpManager.addPopUp() instead of createPopUp().
addPopUp takes an object that has already been instantiated:
var createGoodsWindow:CreateGoodsWindow = new
CreateGoodsWindow(data);
PopUpManager.addPopUp(createGoodsWindow);

Error while transforming XSLT by calling function with Reflection API

Hi,
I'm new to Reflection API. I want to call function from the jar file which is not in my application context. So I have loaded that jar ( say XXX.jar) file at runtime with URLClassLoader and call the function say [ *myTransform(Document document)* ]. Problem is that when I want to transform any XSLT file in that function it throws exception 'Could not compile stylesheet'. All required classes are in XXX.jar.
If I call 'myTransform' function directly without reflection API then it transformation successfully completed.
Following is code of reflection to invoke function

        Object instance = constructor.newInstance(constructorParams);
        Method method = c.getDeclaredMethod("myTransform", methodParamsClasses);
        Object object = method.invoke(instance, methodParams);Following is function to be called with reflection API.

ExternalInterface.call problem with object-orientation

Hi
I am using an swf inside a PDF. In a PDF-context the ExternalInterface-class works much the same as it does within a website. So far calling a function in the document-script works.
The thing now is, that I really try to use an object-oriented approach as often as I can. In this case I have a function I could call using
var jsCaller:Object = ExternalInterface.call("myFunction",parameters);
This works as expected.
However, I have now made that function a method in an object, so I can access it within JS using dot-notation: myCoolObject.myFunction(); This works as well, so the problem is not the function itself. However, the call
var jsCaller:Object = ExternalInterface.call("myCoolObject.myFunction",parameters);
does not work.
This means there's either something I'm missing, or it's a limitation of ExternalInterface, or it's a limitation of externalInterface in a pdf-context.
Anyone to enlighten me?

If EI calls eval it should be able to resolve the object-path. However, this doesn't seem to be the case. Also note that my parameter is an array, so this probably wouldn't work, even if the syntax did.
Anyway, I tested your syntax in my PDF, and it showed the same behaviour as before (i.e. the function in which the EI-call was placed could not be executed, and acrobat claimed there was no such function). It didn't work with my normal function, and not even with a simple console.println-statement that way. So in PDFs it definitely doesn't work like that.
But thanks for the suggestion!

Cannot call functions with this[]

Hello,
I'm in trouble because I need to call functions from MCs with
a variable
name.
I tried to use this[] that should do the trick, but it
doesn't.
Here's what I did in code to try to debug :
- trace what's inside the this[]
- the actual this[]
- a cut and paste of the above trace() with the function call
Of course, both "hardcoded" calls work..; what am I doing
wrong ?
Here's the code :
trace(_parent + "." + buttonName);
trace("_parent." + buttonName);
this[_parent + "." + buttonName].setBtnState("test1");
this["_parent." + buttonName].setBtnState("test2");
_parent.mcBtn1.setBtnState("test3");
_level0.mcInt.mcBtn1.setBtnState("test4");
What am I supposed to feed this[] with ? Path as a string ?
Thanks in advance.
PJ

What you need to feed the array operator is a string or a
variable that can be resolved to a string. And that string needs to
be the sole name of an instance or property of something that can
be found in that object.
So the reason the ones with the "_parent.mcMe" didn't work is
because there is no object with the name "_parent.mcMe" inside of
this. There is a _parent object and inside the parent object there
is an mcMe, but that isn't the same thing.So you need to pick out
the path one item at a time.
this["_parent"]["mcMe"]["testMe"]();
Should also work. And any of those string litterals could be
replaced by a variable which held a string as well. Also notice
that the function at the end can also be referenced since you are
looking inside the mcMe object for some object with a name of
testMe. But the parens which call the function need to be outside
the array access because they aren't part of the name of the
object.

Call function with select arguments

Hi Gurus,
I have problem to call function inside select statements as follow:
select a.ID_ELE2, a.ID_ELE3, a.DT_FIS_YR, c.NU_FIS_PER, c.dt,
(case
when c.ld is null then
GET_LD_CHECK (a.DT_FIS_YR,c.NU_FIS_PER, a.ID_ELE3, a.ID_ELE2) -- 1
-- GET_LD_CHECK ('2009',7, '8010', '7493') --- 2
else
c.ld
end ) description
from ACCOUNT a, TRANSACTION c
where a.DT_FIS_YR ='2009'
and a.ID_ELE3 <> '0000'
and c.TY_SRC not in ('CL', 'CN')
and a.DT_FIS_YR = c.nu_fis_yr
and a.AK = c.AK_FGCHAR
and trim(a.ID_ELE3) ='8010'
and c.NU_FIS_PER <> 14
order by 1,4,5,6
the 1 doesn't output result but the 2 it does! How can pass the select result to the function?
Thanks in advance for your help.
Ben

The statement / function call seems to be ok. So there are not much chances left for your call to return different (=non) values.
1) It could be that you have different values in the column then during your test call.
2) Maybe your function raises an error and that error is supressed in some ugly WHEN OTHERS EXCEPTION => Solution: Get rid of the error handler.
3) datatype conversion. For example if a.dt_fis_yr is a number value, then you should test with number values and not with strings. GET_LD_CHECK (2009,7, '8010', '7493'). Same logic goes for the other paramters, make sure the datatype is correct and matches the function parameter.

if sy-subrc ne 0.
   It means it is RFC call.
endif.

Call function with DML

I have a function that performs DML. I am calling the function from toplink with the following. I get an error
ORA-14551: cannot perform a DML operation inside a query when I try to execute this function. Is there another way to call functions without using select From dual?
String queryFunc = "SELECT " +
"CCU.adjPaymentTrans(#caseID, #obligorPIN, #ccuPIN, #transCd, #payorTp) " +
"FROM dual";
SQLCall sqlCallFunc = new SQLCall(queryFunc);
ValueReadQuery valueReadFunc = new ValueReadQuery(sqlCallFunc);
valueReadFunc.addArgument("caseID");
valueReadFunc.addArgument("obligorPIN");
valueReadFunc.addArgument("ccuPIN");
valueReadFunc.addArgument("transCd");
valueReadFunc.addArgument("payorTp");
valueReadFunc.bindAllParameters();
Vector theArgumentValuesFunc = new Vector(6);
theArgumentValuesFunc.add(caseID);
theArgumentValuesFunc.add(obligorPIN);
theArgumentValuesFunc.add(ccuPIN);
theArgumentValuesFunc.add(transCd);
theArgumentValuesFunc.add(payorTp);
Number amountReversed = (Number)uow.executeQuery(valueReadFunc, theArgumentValuesFunc);

Normally DML is only done from stored procedures, not stored functions, you may want to consider changing the function to a procedure.
To call a function that does DML, you must call the function through a PLSQL call. If you did not require the return value, the code would be:
>>
String queryFunc = "begin " +
"CCU.adjPaymentTrans(#caseID, #obligorPIN, #ccuPIN, #transCd, #payorTp);" +
"end;";
SQLCall sqlCallFunc = new SQLCall(queryFunc);
DataModifyQuery modifyFunc = new DataModifyQuery(sqlCallFunc);
>>
If you require the return value, then the SQL would be:
>>
String queryFunc = "begin ? = " +
"CCU.adjPaymentTrans(?, ?, ?, ?, ?);" +
"end;";
>>
However this would have to be executed through a CallableStatement in JDBC. TopLink currently only supports executing stored procedures as callable statements, so you would need to execute this directly through JDBC. You could also convert the function to a procedure, or wrap the function with a procedure. I believe TopLink 10.1.3 will have support for a StoredFunctionCall that can call DML stored functions.
To get a JDBC connection from a TopLink session uses,
UnitOfWork uow = session.acquireUnitOfWork();
uow.beginEarlyTransaction()
uow.getAccessor().getConnection();
uow.commit();

(JavaScript, CS3) calling functions with arguments on click?

Hi all,
this is getting tricky:
I want to call a function when the user clicks on a button in my scripted application (a javascript window dialog).
Unfortunately, I need to pass several arguments to the function.
According to the scripting documentation, ".onClick" functions won't take arguments.
I would (somewhat reluctantly) work with (global) variables but the function itself is limited to variables within its own scope - blocking all variables set in main()
How should I approach this?
The basic idea is to have people set some settings in the UI and then do some things after they click ok.
The actual work is pretty complicated (replacing colors etc) and needs to be done to a lot of objects so it would make sense to do it in a function.
I'm pretty confused right now and don't know how to proceed.
Any hints are appreciated.
Many thanks,
Mike

It took some tinkering but I got it to work.
But I still don't see how I can access the whole DOM from within the onClick functions:
I can get to the dialog properties (this.parent.parent) but nevertheless don't have any way to access app.documents and such.
I was able to manage my way around by making the whole window a dialog instead of a window - thereby getting a return value from the OK button and being able to run the code from within main().
Still strange, though...
Cheers,
Mike

Call Function with RFC dynamic table

Hi all
I create a function compare TABLE_ENTRIES_GET_VIA_RFC and CTVB_COMPARE_TABLES, everything is.dynamic
it works well but, how could i create a dynamic output parameter for table.
the system show me that RFC and dynamic table don't work.
i don't want line by line i would like to have the real structure inside of the Function i have everything but i can't move the data to the output parameter table .
could somebody help ?

Thx RE (and Mani) for the feedback.
I think that this URL is sufficient to understand how to pass dynamic internal table via RFC function module, whatever it is input or output. This URL says to use a STRING to store the table content in XML format, via CALL TRANSFORMATION ID, and pass this string as parameter. In the calling program, we have to "decode" the XML back into abap data, Just notice that we don't need to create an XSLT, ID is sufficient.
For any other information, open a new thread, or ask a precise question.

Timeline - call function with interpolated values?

Hi there,
I'm currently discovering JavaFX and have the following question.
I would like to make a sequence of calls to a java bean with interpolated values after a button click.
The execution should be handled in a additional Thread and not in the Action handler.
I could do that manually of course, but I'm intrested if JavaFx offers an easy way.
I read something about the commands do and do later, but in Version 1.0 I couldn't find it. Were these Statements removed?
What about Timeline. Can I call the function there? Or can I only assign values to variables?
The part function of a KeyFrame is only called on the Keyframe itself right?
I hope someone can help me on that problem.
Best regards
