Reference variables inside a remote FM

Hi,
Can anyone explain me why I can't use reference variables inside a remote Function Module.
How can then create a dynamic table.
And how can I return back a dynamic table?
Thanks.

Thanks Thomas.
Ok, in general we can't use a reference variable because both application or systems are on separate adress-spaces, therefore it's not possible.
If the kernel was designed for that it could be possible, am I right?

Should i set null those reference variable object created inside of funtion

hi,
I create object inside of a member function . after finish execute that method those variable should set null to be garbage collection or no need ?
   public void sampleFun(){
       Object obj = new Object();
        // some work
     obj = null ; //// ----------- > this need or not ?
}after finished that method execution should i set
   obj = null;explicitly or no need ?? plz

No, there's no need.
When the reference variable passes out of scope, it ceases to exist, so it doesn't reference the object any more. As soon as an object has no references pointing to it, it is available for garbage collection.
Your rule of thumb should be: don't do anything about garbage collection unless you know why you're doing it. And even then don't do it unless you can prove you need to.

Not able to Pass Reference Variables to Deferred task

Hi All,
I am not able to Pass the reference variables to Deferred task, With the following code, I am getting null values (for the passed refs) in Deferred Task.
Code is as:
<Action id='1' name='Set Deferred Task Action' application='com.waveset.session.WorkflowServices'>
<Argument name='op' value='addDeferredTask'/>
<Argument name='type' value='User'/>
<Argument name='name' value='$(empId)'/>
<Argument name='authorized' value='true'/>
<Argument name='task' value='WF_User Deferred Task'/> // Task defination
<Argument name='date'>
<Date>2008-11-19T14:50:18.840Z</Date>
</Argument>
<Argument name='taskDefinition'>
<block trace='true'>
<defvar name='usrObject'> // This is the variable I am passing to 'WF_User Deferred Task'
<new class='com.waveset.object.GenericObject'/>
</defvar>
<invoke name='setAttributes'>
<ref>usrObject</ref>
<map>
<s>accId</s>
<ref>empId</ref>
<s>updStatus</s>
<ref>newStatus</ref>
</map>
</invoke>
</block>
</Argument>
</Action>
<Transition to='End'/>
Please suggest me.
Thanks,
Ravi.

yeah, you don't have your usrObject available in the deffered task however all variables that you put inside the usrObject are avialble. Like <ref>accId<ref> and <ref>updStatus</ref>. If you still need them organized hierarchically, you might try to add one more level to the object before passing it to addDefferedTask
            <block>
              <defvar name='objWrapper'>
                <new class='com.waveset.object.GenericObject'/>
              </defvar>
              <defvar name='usrObject'>
                <new class='com.waveset.object.GenericObject'/>
              </defvar>
              <invoke name='setAttributes'>
                <ref>usrObject</ref>
                <map>
                  <s>accId</s>
                  <s>yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy</s>
                  <s>updStatus</s>
                  <s>xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx</s>
                </map>
              </invoke>
              <invoke name='setAttributes'>
                <ref>objWrapper</ref>
                <map>
                  <s>usrObject</s>
                  <ref>usrObject</ref>
                </map>
              </invoke>

Bind variable inside a package

Can we declare a bind variable inside a package specification?
CREATE OR REPLACE PACKAGE GET_EMPLOYEEDETAILS
IS
PROCEDURE GET_FIRSTNAME(E_ID IN EMPLOYEES.EMPLOYEE_ID%TYPE, F_NAME OUT EMPLOYEES.FIRST_NAME%TYPE);
VARIABLE O VARCHAR2(20);
END GET_EMPLOYEEDETAILS ;
CREATE OR REPLACE PACKAGE BODY GET_EMPLOYEEDETAILS
IS
PROCEDURE GET_FIRSTNAME(E_ID IN EMPLOYEES.EMPLOYEE_ID%TYPE, F_NAME OUT EMPLOYEES.FIRST_NAME%TYPE)
IS
BEGIN
SELECT FIRST_NAME INTO F_NAME FROM EMPLOYEES WHERE EMPLOYEE_ID = E_ID;
DBMS_OUTPUT.PUT_LINE(F_NAME);
END;
END GET_EMPLOYEEDETAILS;
Output:
ERROR at line 4: PLS-00103: Encountered the symbol "VARCHAR2" when expecting one of the following:
:= . ( @ % ; not null range default character
The symbol ":=" was substituted for "VARCHAR2" to continue.
2. IS
3. PROCEDURE GET_FIRSTNAME(E_ID IN EMPLOYEES.EMPLOYEE_ID%TYPE, F_NAME OUT EMPLOYEES.FIRST_NAME%TYPE);
4. VARIABLE O VARCHAR2(20);
5. END GET_EMPLOYEEDETAILS ;
6. /
or is there any alternative for bind variables inside an package
Thanks in advance

The "VARIABLE O VARCHAR2(20);" syntax is the way SQLPlus declared bind variables - it is specific to the client. Because PL/SQL packages and procedures are server code that continue past sessions, its only access to the client environment is what the client gives it - it can't go and create a bind variable in the client.
PL/SQL procedures, functions and packages run from lots of environments, so they cannot access bind variables inside their body - you have to pass any external variables as parameters.
Anonymous PL/SQL blocks can access bind variables.
You can declare package public global variables - just leave out that "VARIABLE". E.g.
CREATE OR REPLACE PACKAGE GET_EMPLOYEEDETAILS
IS
PROCEDURE GET_FIRSTNAME(E_ID IN EMP.EMPNO%TYPE, F_NAME OUT EMP.ENAME%TYPE);
O VARCHAR2(20);
END GET_EMPLOYEEDETAILS ;
For local variables in your procedure, just put them between the IS and BEGIN. Using them in SQL inside the PL/SQL automatically uses them as a bind variable.
create or replace PROCEDURE GET_FIRSTNAME(E_ID IN EMP.EMPNO%TYPE, F_NAME OUT EMP.ENAME%TYPE)
IS
O VARCHAR2(20);
O2 VARCHAR2(21);
BEGIN
O := 'FR%';
SELECT ENAME INTO F_NAME FROM EMP WHERE EMPNO = E_ID and ENAME like O;
O2 := F_NAME || '2';
DBMS_OUTPUT.PUT_LINE(F_NAME);
END;
O is bound in the query.
To access bind variables from anonymous PL/SQL, first declare them in the calling environment. In SQL Plus that's
VARIABLE O VARCHAR2(20);
In Pro*C it's
EXEC SQL BEGIN DECLARE SECTION;
char[21] O
EXEC SQL END DECLARE SECTION;
Then reference it in anonymous PL/SQL with a colon as prefix:
BEGIN
SELECT FIRST_NAME INTO :O FROM EMPLOYEES WHERE EMPLOYEE_ID = E_ID;
END;
This only works for anonymous blocks (starting with BEGIN or DECLARE). As I said, PL/SQL procedures, functions and packages cannot see bind variables from the calling environment

How to Print the Value of a variable inside a PL/SQL package

Hi Friends,
Here is my Scenario
I have a PL/SQL Package. Let us call it Baseline Package.
This Package includes a dynamically built merge Statement.
Execute Immediate v_merge_query.
I have a procedure which replaces which few Keywords from the Package Text and Creates a new one depending on Inputs I provide. (This is something like a Code generator)
Now while Creating the new package, I need to print the Value of v_merge_query.... I Need s Static Query to be Printed inside the new package and not a dynamic query.
My Question is "Is there a way to print the value of the variable inside a different PL/SQL package?
Thanks in Advance,
Mohit

Print where?
That PL/SQL code is server-side code. It runs in an Oracle server process.
That server process does not have a keyboard. Or a screen/monitor. Or display canvas. Or an attached printer.
That server process is incapable of "printing" as that is not its job or responsibility and not part of its environment.
What is can do is record data for the client to look at afterwards. This can be done using static PL/SQL session variables. Or a SQL table.
The former is done by DBMS_OUTPUT - a very primitive interface for writing text into a static PL/SQL string array. That btw resides in expensive private process server memory. The client can query the array after a database call and render the contents.
PS. Also keep in mind that bind variables are critical for performance and server robustness - especially when (ab)using dynamic SQL.

Error Setting Environment Variable inside Listner.ora

Hi,
I am trying to set an environment variable inside listner.ora as follows

but every time I try to start the listner it gives me the following error:

I think that the parenthses, (4444), in the MQSERVER value is causing this. Any ideas on how I can configure it?

Using a variable inside another variable

I'm trying to use one two variable in a package with one variable feeding its value to another variable as follows:
Variable 1 = Count
Variable 2 = File_Name
Variable 1 counts up from 1;I would like to use this value as an input to Variable 2 as follows:
SELECT LOAD_FILENAME FROM DIMSTATS_FILENAME WHERE (SELECT ROW_NUMBER() OVER (Order by FILE_ID) AS RN FROM DIMSTATS_FILENAME) = #DIMSTATS_TEST.count.
How ever I am getting the following Error :
+ODI-1228: Task File_Name (Variable) fails on the target connection DDBSTAGE.
Caused By: java.sql.SQLException: [FMWGEN][SQLServer JDBC Driver][SQLServer]The multi-part identifier "#DIMSTATS_TEST.count" could not be bound.+
I have also noticed that the value of Variable 1 is not being passed to the Select statement above through SQLServer Profiler. If I hard-code the value of #DIMSTATS_TEST.count (Variable1) the query is successful.
How can I get the value of Variable 1 to be passed to Variable 2?
Could someone please help
Thanks

You did not mentioned how you are using those variable .
You need to have these variable inside a package .
It will be like
Variable 1 (Refresh) -------OK-------->Variable 2(Refresh) ------------OK-----> Some other operation .

Passing a reference / variable to a Custom Component

Hi, I was wondering if someone could help me.
It seems like a very simple problem but I cant for the life
of me seem to work out a solution.
I have created a Custom Component that extends from the
UIComponent that consists of a “rev counter” style
clock face etc….
I want to use this component multiple times within my
application – however feed it different data so for example
each “rev counter” on the page will be displaying
different data etc…..
I want to be able to reuse my component and not have to
create a new component every time I add a “rev counter”
to my application, therefore I need some way of passing a reference
/ variable to the component (maybe from the <mx /> tag where
I declare it in the MXML code ??? )
<mx:Application ….
xmlns:comps="components.*" …..>
<comps:RevCounterComp id=”” (add something
here to reference???) />
</ mx:Application>
Doing this will allow me to reuse my ONE custom component
MANY times feeding it different data (different data provaiders for
each instance of the single component)
Hope this makes sense???
Any help / advice is much appreciated,
Thanks,
Jon.

Jon,
jmryan's suggestion is the preferred way to go. This way you
can use the simple MXML syntax that you described in your post.
If your custom component is defined in ActionScript, you can
use setters or the creationComplete event to update the component
when the values are passed in from the tag (they are set *after*
your constructor runs).
Even easier, if your component is defined in MXML, you can
add [Bindable] to your public field and then bind directly to it in
the custom component's MXML code.

Indicating the reference document inside the main document.

Hi,
We have a requirement that indicating the reference document inside the main document. for.e.g: Indicating the sub manuals inside the main manual. Is this possible in SAP DMS. Please suggest me.
Thanks & Regards,
Prasad
Edited by: RPrasad on Jan 4, 2011 5:59 PM

Hi Prasad,
For this you have two options :
1. Use the field Superior document , here you can assign a superior document to sub-document. Configure in DC10 to document
type.
2. Or use Environmrnt -> Document Structure -> Create , here you can create a docuemnt structure means if user is displaying a docuement or using a document for various business activities then user has to refer a document which is assigned in document structure. When someone uses a document if it has a document structure means must refer the assigned document.
Hope this will help.

Is down casting possible in Java objects(reference variables)?

I hope, Java up casting and down casting is possible in Java primitive variables like int float and so on.
My doubt is,Does in object of Java(reference variables) support down casting?

Can i use a environment variable inside a *.sql file?

Hello,
I want to create a external table.
So i am using the command
create or replace directory abc as 'C:\folder'.... inside a sql file.
Now i want the path "C:\folder" to be dynamic as i am using this path in many other places also inside the sql file.So i thought to create a environment variable and put this value there.I tried using as %PATH% but it gives error..... where %PATH%=C:\folder.
Can i use a environment variable inside a *.sql file?
But how to do that or is there any other way.
Thanks

Actually what i want is the path "C:\folder" is not fixed it can be anything which i may not know the user may decide it later. Not supported. A directory object refers to a specific physical location (directory/folder) on a file system. Not a path.
You can work around it by (creating and) using a function (running under a super user schema with authid definer privs). The caller (e.g. schema scott ) calls it with a physical path. E.g. GetDirectoryObject( 'C:\folder\2010\feb\week4' ).
This function determines if there is an existing directory object for the path. If not, it uses a wildcard search to determine if there are any directory objects for parents in the path (e.g. for C:\folder\2010\feb or C:\folder\2010 or C:\folder ).
If it finds a directory object, it interrogates the data dictionary to determine if the caller, schema scott for example, has read/write access on that directory object. If it has, it creates a new directory object and grants the caller read/write access to it. The function then returns the name of the directory object to the caller.
The caller thus do not deal directly with directory objects. The function returns the object name given a physical path as input. Also, only a single base directory needs to be created (e.g. for C:\folder ) and access granted to the schema on it. Any sub-directory in that base directory can now be dynamically accessed by the schema.

I want to access that BEA instance variable inside of a external java class

Hi,
This is N.pradeep. I am a java programmer, and I am new to BEA AquaLogic BPM studio5.7. I have a question regarding how to retrieve an instance variable of BEA Aqua Logic to an external Java Program. i.e. I want to access that BEA instance variable inside of a external java class, and vice versa.

You can use PAPI or PAPI-WS for accessing BPM instance variable from a Java code, thougt I am not sure how the reverse will be done. Assuming that you are aware aof PAPI-WS and have created the necessary stubs out of the PAPI-WS WSDL using Axis, you can access instance variables using the API's or operations defined therein.

Using PHP variable inside MySQL recordset

Can someone let me know if this is possible? I'm trying to
use a variable inside a recordset. The code below is what I have at
present but it white screens me when I try open it the page in the

Any chance you can help me with phase 2.
I'm trying to get determine $qualificationchoice by the

Here's what I have right now:
