Can we pass the HashMap object to Stored procedure using toplink

Can we send the java.util.Map object as input to the stored procedures.
Can any one please tell how we can do this using toplink.
I tried to do that by doing following steps
1. Crated the
-- Column Name - Value Pair
CREATE TYPE col_data_pair IS OBJECT (column_name varchar2(50), data VARCHAR2(32767))
2. create or replace PROCEDURE XL_MAP_TEST (poData In COL_DATA_PAIR) as
v_timestamp TIMESTAMP;
BEGIN
INSERT INTO RECON_ATTR_UD_TFCHILD(RECON_TABLE_KEY, RE_KEY, RECON_UD_TESTFORM_KEY,RECON_UD_TFCHILD_GROUP)
values (RECON_TABLE_KEY_SEQ.NEXTVAL,15, 25 ,'Persistentss23');
END XL_MAP_TEST;
3. .

Hi
Thanks for your inputs. Can you please send me the code stuff how we can use ObjectRelationalDescriptor. I tried to do that by doing following steps
1. Crated one class
oracle.InputOfTypeMap poData =
                    new oracle.InputOfTypeMap();
poData.setKay("ddd");
poData.setValue("ddd");
2. oracle.toplink.objectrelational.ObjectRelationalDescriptor descriptor =
     new oracle.toplink.objectrelational.ObjectRelationalDescriptor();          descriptor.setJavaClass(oracle.iam.reconciliation.vo.InputOfTypeMap.class);
          descriptor.setStructureName("COL_DATA_PAIR");
          descriptor.addFieldOrdering("column_name");
          descriptor.addFieldOrdering("data");
          descriptor.addDirectMapping("key", "column_name");
          descriptor.addDirectMapping("value", "data");
3. I was not sure how to use this further StoredProcedureCall
Can you plese help me, how we can do that?

Calling an Oracle stored procedure using Toplink API - Please help

Hi,
We are evaluating Toplink as a possible data access layer in large service-oriented application. The ability to call db stored procedures from within business object layer is crucial for our architechture.
I am trying to follow toplink application developer's guide examples on how to call stored procedures using toplink.
I have the folling java code:
call.setProcedureName("PR_ROMAN_TEST");
call.addNamedArgument("IN_PARAM");
call.addNamedOutputArgument("OUT_PARAM");
ValueReadQuery query = new ValueReadQuery();
query.setCall(call);
query.addArgument("IN_PARAM");
Vector params = new Vector();
params.addElement(new Integer(5));
Number result = (Number) session.executeQuery(query, params);
This generates the following SQL statement:
BEGIN PR_ROMAN_TEST(IN_PARAM=>5, OUT_PARAM=>?); END;
An attempt to execute it causes a
java.sql.SQLException: Invalid column index.
As I understand it, this exception is thrown because of the "?" in place of the out-parameter value holder.
The SQL statement that I would want toplink to generate and execute should look like:
DECLARE result number; BEGIN PR_ROMAN_TEST(IN_PARAM=>5, OUT_PARAM=>result); END;
, but how do I achieve it and how do I capture the return value, all using toplink api?
Please help
Thank you in advance,
Roman

How can I get the printed message of stored procedure in JPA

Hi, I'm using JPA to invoke stored procedure in database, a segment of the sproc is like below:
if @create_type != 'a1' and @create_type != 'a'
     begin
     print 'create type must be either ''a1'' if you pass in A1 ID, or ''a'' if you pass in User ID'
     select 0 as "Result"
     endI can get the 0 as the result, it means business operation failed currently, but how could I get the message of 'create type must be either ''a1'' if you pass in A1 ID, or ''a'' if you pass in User ID'?
That information is important as it indicates why the operation failed.
Thanks

how can i get rows count returned by stored procedure in oracle sql developer?
Procedures do NOT return a value - functions return a value.
A procedure executes whatever code it contains. That code could contain many queries that produce many row counts.
Does your procedure take one or more IN, OUT or IN OUT parameters?
See example 8-1 for an example of executing a procedure that has an OUT parameter.

Passing DATE parameters to Oracle Stored Procedures using ADO

Does anyone know how can I pass a date parameter to an Oracle
Stored Procedure? The IN parameter of the procedure is of type
DATE and the ADO parameter is of type DBDate (I've tried Date
and DBTimeStamp,too). The execution freezes at "Cmd.Execute".
Can anyone suggest a solution?
Thanx for any tips

As far as I know the documentation on CR & stored procedures says that the REF CURSOR has to be a strongly bound one.
Could you go into a little more detail? Do you mean I should put a multi-valued parameter into a REF CURSOR? Can you post some code snippets here?

How to pass the parameter of a stored procedure to iReport

Hi... i don't know how to pass the parameter of the stored procedure to the iReport.
In the Report Query, i tried
1. sp_storedprocedure ' value'
2. sp_storedprocedure +''''+$P{parameter}+''''+
3. sp_storedprocedure +$V+$P{parameter}++$F($F is a variable having a value of ' (a single quote))may you enlighten us please? thank you

For M$ SQL server I find that it only works when U use the fully qualified name...
e.g. catalod.dbo.my_procedure_name 'variable'
My full query in the Report Query window is something like this:
EXEC arc.dbo.jasper_Invoice 1000
Note that you may find that selecting from VIEWS / TABLES fails for no apparent reason and iReport will prompt you with the usual very unhelpful (we have what we "pay" for) prompt, stating that "The document is empty".
To work around this issue, where a statement like "SELECT * FROM arc.dbo.acc_invoices WHERE Invoice_id=1000" does not work, simply create a PROC, something like:
CREATE PROC jasper_MyProc (@my_rec_id integer) AS
SELECT * FROM arc.dbo.acc_invoices WHERE Invoice_id= @my_rec_id integer
...to wrap your SELECT statement, then call the PROC

Passing XMLType Data into oracle stored procedure using JDBC

Hi Friends,
I have requirement where my oracle stored procedure accepts XML file as an input. This XML File is generated in runtime using java, I need to pass that xml file using JDBC to oracle stored procedure. Please let me know the fesibile solution for this problem.
Following are the environment details
JDK Version: 1.6
Oracle: 10g
Server: Tomcat 6.x
Thanks in Advance

A 'file' is a file system entity. There is no way to pass a 'file' anywhere. Not PL/SQL. Not java.
Now you can pass a file path (a string) in java and to PL/SQL.
Or you can pass xml data (a string) in java and to PL/SQL. For PL/SQL you could use eithe a varchar2, if the xml is rather small, or a blob/clob.

How to pass the java object into the spring controller

Hi Friends
When I hit the url at the first time my call goes to the spring controller and sets the userDetails objects in the modelAndView.addObject("userDetails", userDetails.getUserDetails()) and returns the userDetails.html page. if I click any link in the same page i want to pass same (userDetails) object thru javascript or jquery and calls the another(controller) method and returns the same (userDetails.html) page.
It means how can i pass the java object thru javascript or jquery and calls the controller. if i get the same object in my controller i can avoid calling the db again. please help me out to resolve this issue. i am tired of fixing this issue.
Regards
Sherin Pooja

If you want to avoid calling the database again then cache the data.
However before you do that make sure that calling the database, in the context of YOUR system, is going to be an actual problem.
For example there is absolutely no point in caching a User object when only one user an hour is actually using the system.

How can I get the Doc object from any other object?

Dear colleagues,
in FrameScript it is dead-simple to get to the document part of any object, just add .Doc to the variable.
How can I achieve the same with ExtendScript? I amtired of passing the document object next to AFrames or Pgfs along into subroutines, because those objects already contain the information about their document. But how do I access this?
Thanks for pointers,
- Michael
PS: Almost the same is true for the page an object lives on. With FrameScript we use .Page, with ExtendScript you have to move up the object tree until you reach the UnanchoredFrame.PageFramePage…
PPS: It would be great to see some convenience properties like .Doc and .Page implemented natively.

I'll preface this response by admitting this far from an elegant solution, but I did write a function addressing this question, mostly as an exercise.
If passed an object with an InTextFrame property (Pgf, AFrame, Cell, Fn) that resides in an open document, the function will return the Doc object. Otherwise, it returns undefined.
function getParentDoc(testObj) {
    //Get object for current page
    try { var curPage = testObj.InTextFrame.FrameParent.PageFramePage; }
    catch(er) {return;}
    //Step backwards to first page in document
    var prevPage = curPage.PagePrev;
    while (prevPage.ObjectValid())
        curPage = prevPage;
        prevPage = prevPage.PagePrev;
    //Compare with first pages of open documents
    var testDoc = app.FirstOpenDoc;
    while (testDoc.ObjectValid())
        if (curPage.id==testDoc.FirstBodyPageInDoc.id) return testDoc;
        testDoc = testDoc.NextOpenDocInSession;
    return;
To your PPS: Rather than seeing the native framework grow bloated to address additional features, I would love to see Adobe and other developers publish libraries of useful functions and class extensions.

How can I pass the value to another frame?

Hi all,
The following is part of my coding of a frame. Once i click on the jButton2, the selected value will be stored into a variable named NAME and the value will be displayed by a label in same frame. At the same time, a new frame named TESTING3 will be set to visible.
private void jButton2ActionPerformed(java.awt.event.ActionEvent evt)
// TODO add your handling code here:
    String name = (String)jList1.getSelectedValue();
    jLabel1.setText(name);       //display the value in a label in same frame
    new testing3().setVisible(true);     //a new frame set to visible
}      Question: How can I pass the value to TESTING3 frame and display it on that frame?
Thanks,
ning.

just make an archive that save that variable and them get them from de clase were you save it
public class sav {
String n;
public sav {
n="";
public void addn(String x){
n=x;
public String shown(){
return n;
and them save it from the frame
sav sun = new sav();
sav.addn(f);
them call it from the other frame
sav sin = new sav();
String s = sin.shown();
label.setText(s);
and i think thats you want to do if its not please explain me better

Can we cache the remote object?

hi,
can we cache the remote object?
is this right way of doing?
please suggest me
regards
crr

Yes, caching EJBHome, EJBObject, and Remote business references is fine. They can also
be portably stored in an HttpSession. However, when caching in the web tier you must still
be careful to prevent concurrent access to the same stateful session bean. The fact that
remote references to stateful session beans can be cached does not guarantee they can
be accessed by more than one client at a time.

How to verify the user information pass by the form with a stored procedure?

Hi,
I would like to know how to verify user information pass by the form with a stored procedure.
I want make a portal which accepts to new user registration, but I want verify the new user's informations (like the name don't contain a number etc).
Thanks for your help
regards
jla

Hi Samson,
You can use the UI API to do this. You can catch the form_ADD event and then validate the input from the users. You can even block the event from completing (and stop the document from being added) if your code finds some incorrect data using the bubbleEvent functionality.
I don't have one specific example to show you, but if you look at some of the SDK samples (for example C:\Program Files\SAP\SAP Business One SDK\Samples\COM UI\VB.NET\02.CatchingEvents) to see how to work with events, you can then create your own validation to ensure the users data is valid.

Niall

Is it possible to pass TABLE as the output parameter in stored procedure

Hey Experts,
Is it possible to pass TABLE as the output parameter in stored procedure.
eg
create procedure spGetData
@tableName as TABLE(intValue INT NOT NUL)
as

You can use OPENQUERY or OPENROWSET, as mentioned above, to make stored procedure results table like. There are
some limitations with these methods:
http://technet.microsoft.com/en-us/library/ms188427.aspx
In OPENQUERY this-sql-server-instance can be used instead of a linked server name. It requires setting data accces server option:
exec sp_serveroption @server = 'PRODSVR\SQL2012'
,@optname = 'DATA ACCESS'
,@optvalue = 'TRUE'

How can i pass the Input value to the sql file in the korn shell ??

Hi,
How can i pass the Input value to the sql file in the korn shell ??
I have to pass the 4 different values to the sql file and each time i pass the value it has to generate the txt file for that value like wise it has to generate the 4 files at each run.
can any one help me out.
Raja

Can you please more elaberate., perhaps you should more elaberate.
sqlplus is a program. you start it from the korn shell. when it's finished, processing control returns to the korn shell. the korn shell and sqlplus do not communicate back and forth.
so "spool the output from .sql file to some txt file from k shell, while passing the input parameters to the sql file from korn shell" makes no sense.
