Calling value from function

is there a way to call or print the value returned by a function/dbExecute?
<database:dbSetParam name="n" value='<%=request.getParameter("n")%>' scope="page" />
<database:dbSetParam name="final" value="dann" scope="page" />
<database:dbExecute connId="conn" scope="page" output="yes" bindParams="final n">
begin ? := trunc(crbcis.p_session.open_session_from_nonce(?)/100000); end;
</database:dbExecute>

No, this does not appear to be possible. Probably becuase the setParams is expecting an
in parameter, but the function return is an out. The only alternative I have is for your function to insert the result into a table, then use the dbQuery tag to retrive the result. Please let us know if you think this is worth creating an enhancement request to support this.

Error getting return value from function

Hello
I'm getting a error calling a function with ODP.NET from C#
Code:
OracleCommand oraCom = new OracleCommand("NORMALIZACION.nif",oraCon);
oraCom.CommandType = CommandType.StoredProcedure;
OracleParameter param1 = new OracleParameter("numnif",OracleDbType.Varchar2);
param1.Value= "73667866A";
param1.Direction = ParameterDirection.Input;
OracleParameter param2 = new OracleParameter("nif",OracleDbType.Varchar2);
param2.Size = 10; //FIXME line
param2.Direction = ParameterDirection.ReturnValue;
oraCom.Parameters.Add(param1);
oraCom.Parameters.Add(param2);
oraCom.ExecuteNonQuery();
nif_norm = oraCom.Parameters["nif"].Value.ToString();
if i write the FIXME line i get a error (ORA-06502) complaining about the size, no matter the value i wrote.
If i don't write the FIXME line, it works but nif_norm is always empty, although the function i call is a single return 'Hello';
Where am I wrong??
Any help, examples with varchar2 as return value???
BTW: the same code with the MS provider for Oracle works fine.

Good point -- i shall do so.
What I think I'm missing, in my quest for ODP.NET competence, is a solid set of example code. I've searched around and found various fragements here and there, but when it comes to data access from .NET there must surely be some finitie set of possibilities (if we can discount bad practices like building dynamic SQL statements without bind variables).
For example, possibly in increasing order of complexity ...
* Read a single value from a SQL statement ... "select emp_name from emp where rownum < 2"
* Read a single value by passing in a parameter ... "select emp_name from emp where user_id = :?"
* read multiple values ... "select emp_name from emp where user_id in (:?,:?)"
* execute a stored procedure with no in or out parameters
* retreive a value from a function with no parameters
* pass a parameter to a stored procedure
* read an out parameter from a stored procedure
Then work with in and out ref cursors, blobs, whatever.
Thoughts?

How to get the returned value from Functions with Callable statement?

I was glad to find that stored procedures can be invoke with Java class code by the object of Callable statement like :
String stmt = "BEGIN departments_pkg.do_select(?,?,?); END;";
and getting the output variables by
populateAttribute(DEPARTMENTNAME,st.getString(2),true,false);
But i would like to get values returned from FUNCTION other than stored procedure, how can i achieve it? Thanks a lot!

Here is my code
PROCESS BEFORE OUTPUT.
MODULE STATUS_1202.
MODULE subscreen_find.
CALL SUBSCREEN SUBSEARCH INCLUDING sy-cprog dynnr.
PROCESS AFTER INPUT.
MODULE USER_COMMAND_1202.
CALL SUBSCREEN SUBSEARCH.
MODULE subscreen_find.

          dynnr = 0110.
        when '02'.
          dynnr = 0111.

Adding Additional Columns in LOV,That column capturing values from function

My requirement:
Adding Additional Columns in LOV,That column values capturing values returned by function.....
Give me the ides to achieve this...

Hi Subramaniam,
If your requirement is to call a Database function then please make use of the below code ,
import java.sql.CallableStatement;
import java.sql.SQLException;
import oracle.apps.fnd.framework.server.OADBTransactionImpl;
OAApplicationModule oaapplicationmodule = oapagecontext.getApplicationModule(oawebbean);
OADBTransactionImpl txn = (OADBTransactionImpl)oaapplicationmodule.getOADBTransaction();
CallableStatement cs = txn.createCallableStatement ("begin :1 := xxpackageName.xxfunctionname(:2,:3); end;",-1);//Replace your function Name
try
cs.registerOutParameter(1, Types.VARCHAR);
cs.setString(2,InputParam1); // InputParam1 is the name of variable captured from the OAF page and passed into function as input parameter
cs.setString(3,InputParam2); //InputParam2 is the name of variable captured from the OAF page and passed into function as input parameter
String outParamValue = null; // outParamValue will capture the value returned by function .
cs.execute();
outParamValue = cs.getString(1);
catch(SQLException sqle)
throw new RuntimeException(sqle);
finally
cs.close();
Let me know if its not clear .

Call BEx from function modules.

Hi,
I'm trying to run BEx (Excel) from an abap Exit. Using the debugger I have observed that it is necessary to call the rsah_launch_excel function module passing some parameter (i.e. workbook id) but don't know if it is necessary to copy and modify the called program ( RRMX_START_EXCEL).
Any suggestion about the coding will be well appreciated.
Thanks in advance.
Giovanni

Use SUBMIT Program statement ... i.e,

Call layout from function

Hi ,
i have a function that call to a layout.
my problem is that when i ran the function, the layout not get the parameters that i pass to her.
how can i pass a parameters from function?
thanks,
dana.

Hi Sanjiv!
of course... but I don't remember now exactly the final code, but the problem was in the code lines:
i_program_name = sy-cprog
i_inclname = sy-cprog
I had to 'play' with this parameters to get the correct results because I had my report like an include... and then the parameters were different (I hope to explain it well!)

Return value from function within package

Hi,
There is a function within a pl/sql package that I am trying to get data from. The problem is that the data returned can be up to 32,767 chars (varchar2 limit).
It accepts 3 input parameters and returns on varchar2.
The only way I can get it to work is using this syntax:
==================================
variable hold varchar2(4000);
call TrigCodeGenerator.GenerateCode(VALUE1', 'VALUE2','VALUE3') into :hold;
print hold;
=====================================
However, if the data returned is greater than 4000 then I get this error:
ERROR at line 1:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at line 1
I can't increase the size of the variable (hold) as there seems to be a limitation on this type of variable.
Also, I am running this in sql plus worksheet. Will it limit the display of the data (assuming, that someone can get the whole 32,767 chars displayed back) ?
Thanks in advance,
Ned

Never mind,
I declared the variable hold as clob and set the long and longchunksize parameters to 100,000 and it seems to work.

Getting value from Function stored in a schema and Watching the value of objects

hi
i'd like to display a labelA which is from a query -> (SELECT NAME FROM TABLE1 WHERE NAME = GetA). GetA is a function which I created in SchemaA. GetA returns a varchar2. In this case.. how can i do that ?
should i write the PL/SQL in the format trigger of this labelA ? if yes, then what should i write in the PL/SQL format trigger ? or should i create another query in Data Model ?
And how do get hold of this labelA's value(or the result returned by the query) in the parameter form?
And lastly is there a way to trace the value of some report objects ?
should i use SRW.MESSAGE ? to print out the 'watched' value ? or any other alternatives ?
what is the url that takes me to learn all these ?
I got this error "REP-1401: 'beforepform': Fatal PL/SQL error occurred." when i initialize the bind variable to a function (GetA)stored in Schema A ---> :P_A := GetA in the before_parameter_form of report trigger;
anything wrong with the above assignment ?
are there any difference between stored procedure like function, package in the database and those in in PL/SQL Library of report builder ???

Passing values from function to unbound field on report

i've created a function to calculate certain values. i would like those values to be assigned to fields i've put on the report (these fields have no source) at runtime. how is this done. i've tried the ':' used for binding variables (parameters)...but in this case, it's not a 'parameter' in that sense.

How about using placeholders? Take a look at the online help for placeholders as it sounds like it should fit your needs. You can have a formula column that calls the function and sets the values of the placeholders. However, please note that if the function sets the placeholders directly, the placeholders will have a indirect dependency on the formula column and this could cause problems at run time. You will need to use srw.reference to establish a direct dependency in that case. srw.reference is also in the online help. If you run into problems, Support should be able to assist you with this.
Hope that helps, Toby

Call value from jsp

%>

<table width=50% height=50 border=0>
<form name="matchForm" action="second.jsp" method="post">
<input type="hidden" name="action" value="MATCH">
<tr>
<td width=150>Product Description</td>
</tr>
<tr>
<td class="formlabel"><input type="text" name="productDesc" maxlength="100" size="50" value="<%=productDesc%>"/>�</td>
</tr>
<tr>
<td><input type="submit" class="formbutton" value="Find Product" />�</td>
<tr>
<td width=150>Product List:</td>
</tr>
<tr>
<td>
<input type="hidden" name="productlist" value="<%=request.getParameter("productlist")%>"><%=request.getParameter("productlist")%></td>
</tr>
</form>
</table>
<table cellspacing="0" cellpadding="0" height=50 border="0" width="70%">
<form name="confirm" action="third.jsp" method="post">
<input type="hidden" name="action" value="CONFIRM">
<tr>
<td class="formlabel"><input type="submit" value="Submit" name="Submit"/></td>
</tr>
</form>
</table>
second.jsp:
<%
String productlist = (String)session.getAttribute("productlist");
String prod = (String)request.getParameter("productlist");
%>
<%String temp =somevalue+prod;%>
<td width=250><a href="AssignProducts.jsp?productlist=<%=temp%>">whatever<a></td>
My problem is, how do I call productlist in my third jsp?
</a>

I assume they click on the href, then you would use request.getParameter("productlist");
Request.getParameter always returns strings, no need change the type like you are doing in the second JSP.

Getting values from a function module called in a WDA method

Friends,
I am trying to execute a function module from WDA.
I have created a service call for the function module. The function module takes values from the user, looks up the corresponding values of another field and returns the values in an internal table.
I am using the "Method Call in Used Controller" of WD Code wizard to call the function module.
When the event handler method containing the call to the function module is executed, nothing happens.
I am not sure how to pass values to the function module and to get the return values from the function module.
I am new to using function modules from WDA. Please help me out.
Thanks and Regards.

Rashmi,
Is the function module intended to collect input data from the UI and process it? - Yes
If yes, then the input (importing parameter) to the Function Module is a table of values (which should be ideally from the context mapped to the Table UI Element). - The importing parameter is a single value NOT a table and is mapped to the view context.
Now this table UI Element is bound to the view controller context , which in turn is mapped to the component controller context. And you are indeed being able to read the value of this internal table in the component controller method where the function module is being called by means of get_static_attributes_table (Is this right? - Yes, I am able to read the table of values that is passed from the component controller view to form view context by using get_static_attributes_table.
Or are you being able to read it in the event handler method of the view controller and not being able to read it in the component controller method) -
The function module takes a single value as import parameter and returns a table of values as return value.
It works fine when no importing parameter is being used and returns the table of values that is getting passed from component controller context to form view context when i am able to read it using get_static_attributes_table.
Now the question is: how to pass the import parameter value to the function module. I assumed since the importing parameter is a context node (like the return values are), i should set the value ( captured when the user enters the value in the form) to the importing parameter context attribute using set_attribute method. Since it is mapped to the component controller context, i assumed it will get passed and the method will take it as input parameter.
Let me know if my assumptions are correct regarding passing the import parameters and what is missing here.
Thanks and Regards.

Getting Return values from RFC function call with visual basic

Hi,
I am creating a sample app to connect to a SAP system which call its RFC functions created with ABAP. It was known that the function will return more than 1 return values.
   SAP Function name ==> "ZFMTP_RFC_GET_RESULT"
        Export parameters (to SAP):
                - Student Name [char 10]         ==> "STUNAME"
                - Student ID         [char 20]        ==> "STUID"
       Return values (From SAP):
                - Results [char 10]        ==> "RESULT"
                - Remarks [char 200]        ==> "REMARKS"
i have managed to get sample codes for connecting and call a RFC function with vb but they only get a return value. How do i retrieve multiple return values like the above function "RESULT" and "REMARKS"?
Here's my vb code to accessing the function
        Dim R3 As Object
        Dim FBFunc As Object
        Dim returnFunc As Boolean
        Dim connected As Boolean
        R3 = CreateObject("SAP.Functions")
        R3.Connection.Client = "000"
        R3.Connection.User = "BCUSER"
        R3.Connection.Password = "minisap"
        R3.Connection.Language = "DE"
        R3.Connection.System = "dtsystem"
        R3.Connection.Applicationserver = "xxx.xxx.xxx.xxx"
        connected = R3.Connection.Logon(0, True)
        If connected <> True Then
            MsgBox("Unable to connect to SAP")
        End If
        FBFunc = R3.add("ZFMTP_RFC_GET_RESULT")
        FBFunc.exports("STUNAME") = "Jonny"
        FBFunc.exports("STUID") = "12345"
        returnFunc = FBFunc.Call() <<== How do i get the return value? or RESULT and REMARKS of the RFC Function?
thanks alot.

expFillRet.Value = "1"
''' Call change password function
