How to pass out multiple rows from EJB method?

I need a sample for passing multiple rows from a EJB query method
(using SQLJ). All I found in existing sample code is query on a
single row and pass out as a bean class e.g Emp class with some
getXX() method.
What I'm currently doing is to convert the Iterator to a Vector
and pass the Vector out, which means I've to code a bean class,
use a Vector and later use a Enumeration to read the result. Is
there a simpler way to receive multiple rows from EJB?
In EJB:
while ( empIter.next() ) {
EmpVect.addElement( new Emp( emps.empNo(), emps.eName(),
emps.job(), emps.deptNo()) );
return EmpVect;
In client:
Vector empVect = empEJB.getEmployees(123);
Enumeration employees = empVect.elements();
while ( employees.hasMoreElements() ) {
emp = ( Emp ) employees.nextElement();
System.out.println(" " + emp.getEName());

Hi Ankit,
There is a workarround that requires some excel work.
Here you need to follow the above mentioned steps along with this you need an additional combo box (wont be displayed at runtime, it will fetch the entire data if we select blank for the first combo box).
Now suppose we are using 2 combobox C1 and C2 and our data is from B3 to F6.
Now for C1 (one we are using for selection)
1. select the labels as Sheet1!$B$2:$B$6 (a blank cell is added for all selection)
2. Insertion type as filtered Rows
3. Take source data as Sheet1!$B$2:$F$6 (includeing one blank row)
4. selected Items as none
5. for C2 labels as Sheet1!$A$3:$A$6 source data as Sheet1!$B$3:$F$6 destination as Sheet1!$B$14:$F$17.
6. Selected Item : Sheet1!$B$9 (blank Type dynamic). So it will select the entire table, if nothing is selected.
7. take a Grid component and map it to Sheet1!$H$9:$L$12. use formula as =IF(IF($B$9="",B14,B9)=0,"",IF($B$9="",B14,B9)) on cell H9. Where we take H6 to L12 as final data set. Tis will become the data for next set fo Combo box for further selection.
8. follow the same steps for other combobox selections.
9. control the dynamic visibility of grids on the basis of Destination cell (like B9).
Revert if you need further clarification.

Let's say for example user have to the use the form to enter all 10 items or few like 5 on their stock form into 4 different textbox field each lines of your form, however these items go into a "Stock_table" under Single insert transaction query when submit button is pressed.
Please anyone help me out, on how to get this concept started.

Hello,
I have a way to do this, but it would take some hand coding on your part. If you feel comfortable hand writing php code and doing manual database calls, specificaly database INSERT calls you should be fine.
Create a custom form using the ADDT Custom Form Wizard that has all the rows and fields you need. This may take a bit if you are adding the ability for up to 20 rows, as per your diagram of the form area. The nice thing about using ADDT to create the form is that you can setup the form validation at the same time. Leave the last step in the Custom Form Wizard blank. You can add a custom database call here, but I would leave it blank.
Next, under ADDT's Forms Server Behaviors, select Custom Trigger. At the Basic tab, you enter your custom php code that will be executed. Here you are going to want to put your code that will check if a value has been entered in the form and then do a database INSERT operation on the Stock_table with that row. The advanced tab lets you set the order of operations and the name of the Custom Trigger. By default, it is set to AFTER. This means that the Custom Trigger will get executed AFTER the form data is processed by the Custom Form Transaction.
I usually just enter TEST into the "Basic" tab of the Custom Trigger. Then set my order of operations in the "Advanced" tab and close the Custom Trigger. Then I go to the code view for that page in Dreamweaver and find the Custom Trigger function and edit the code manually. It's much easier this way because the Custom Trigger wizard does not show you formatting on the code, and you don't have to keep opening the Wizard to edit and test your code.
Your going to have to have the Custom Trigger fuction do a test on the submitted form data. If data is present, then INSERT into database. Here's a basic example of what you need to do:
In your code view, the Custom Trigger will look something like this:
function Trigger_Custom(&$tNG) {
if($tNG->getColumnValue("Item_1")) {
$item1 = $tNG->getColumnValue("Item_1");
$textbox1_1 = $tNG->getColumnValue("Textbox_1");
$textbox1_2 = $tNG->getColumnValue("Textbox_2");
$textbox1_3 = $tNG->getColumnValue("Textbox_3");
$date1 = $tNG->getColumnValue("Textbox_3");
$queryAdd = "INSERT INTO Stock_table
(item, Qty_In, Qty_Out, Balance, Date) VALUES($item1, $textbox1_1, $textbox1_2, $textbox1_3, $date1)"
$result = mysql_query($queryAdd) or die(mysql_error());
This code checks to see if the form input field named Item_1 is set. If so, then get the rest of the values for the first item and insert them into the database. You would need to do this for each row in your form. So the if you let the customer add 20 rows, you would need to check 20 times to see if the data is there or write the code so that it stops once it encounters an empty Item field. To exit a Custom Trigger, you can return NULL; and it will jump out of the function. You can also throw custom error message out of triggers, but this post is already way to long to get into that.
$tNG->getColumnValue("Item_1") is used to retrieve the value that was set by the form input field named Item_1. This field is named by the Custom Form Wizard when you create your form. You can see what all the input filed names are by looking in the code view for something like:
// Add columns
$customTransaction->addColumn("Item_1", "STRING_TYPE", "POST", "Item_1");
There will be one for each field you created with the Custom Form Wizard.
Unfortunately, I don't have an easy way to do what you need. Maybe there is a way, but since none of the experts have responded, I thought I would point you in a direction. You should read all you can about Custom Triggers in the ADDT documentation/help pdf to give you more detailed information about how Custom Triggers work.
Hope this helps.

How to pass the NEW row from a trigger to a procedure

I want to pass all NEW values from a trigger to a procedure.
I wish to use a %ROWTYPE or similar,
and I want neither to assigne them nor pass them one by one.
Any suggestion?
Thanks in advance

hi vittorio
i have a solution but im very sure it is not exact answer to your question . it will definitely help you .
create table temp_type as select * from emp where 1 = 2;
create or replace procedure emp_ins(emp_row emp%rowtype) as
pragma autonomous_transaction;
begin
insert into temp_type(empno,ename) values(emp_row.empno,emp_row.ename);
commit;
end;
create or replace trigger emp_ins_trig before insert on emp for each row
declare
/* empr emp_types.emprowtype%type;*/
empr emp%rowtype;
begin
empr.empno := :new.empno;
empr.ename := :new.ename;
emp_ins(empr);
end;
/unfortunately , in oracle we dont have a facility to access the members of a record or recordset by their position
Such facility is very much there in Visual Basic , similar programming tools.
we can access the members of a recordset by the index position ( here index means the position of the field)

How to filter out multiple rows , using multiple selection criteria ?

Dear Expert's,
I am stuck with a problem while designing my dasboard.
I have data in the following format.
Year - Quarter - Customer - Division - KF1 - KF2
2005 - Q1 - SAP - Consulting - 10 - 20
2005 - Q2 - IDE - Food - 20 - 10
2005 - Q2 - SAP - Jets - 12 - 11
2006 - Q2 - RAM - Jets - 11 - 11
What i wish to do, is to create radio box(for selection) to choose any Year, Quarter , Customer & Division
eg if the user chooses 2005 , i want to display 3 line entries
2005 - Q1 - SAP - Consulting - 10 - 20
2005 - Q2 - IDE - Food - 20 - 10
2005 - Q2 - SAP - Jets - 12 - 11
if the user further selects quarter - Q2 (without disturbing the selection on for year ) the result should be
2005 - Q2 - IDE - Food - 20 - 10
2005 - Q2 - SAP - Jets - 12 - 11
If the selection from year is removed (still maintaining the selection on quarter Q2 ) the result should show
2005 - Q2 - IDE - Food - 20 - 10
2005 - Q2 - SAP - Jets - 12 - 11
2006 - Q2 - RAM - Jets - 11 - 11
Simply i need to create a filer for all the fields.
The issue that i am facing with filer component is that - 1 - it returns only one desitnation row , 2 - you can only get Key values in result set

Selecting multiple rows from List-component

Hi
Could someone give me an example how to programmatically select multiple rows from List-component?
I know that this selects one row: lst_example.selectedIndex = 1;
But how about selectin indexes 1,2 and 4 for example?

selectedIndices
A Vector of ints representing the indices of the currently selected item or
items...
var si:Vector.<int> = new Vector.<int>;
si.push(1);
si.push(2);
si.push(4);
list.selectedIndices = si;

Pass multiple rows from sp to calling prog

I have a stored procedure using cursor to get multiple rows from the db, how can I pass these rows to the calling prog? Is the out variable returns the last row only?
This is what I did:
Create or replace procedure mysp (
var1 in number,
var2 OUT number,
) as
Cursor mycor is
select * from emp;
begin
for cors in mycor loop
var2 :=cors.ename;
end;

I think you need to do in similar way as follows:
CREATE OR REPLACE PACKAGE sp_dev_sel_all_devicesPKG AS
TYPE RT1 IS RECORD (
sp_dev_id tbl_device.dev_id%TYPE,
sp_dev_name tbl_device.dev_name%TYPE,
sp_err_code tbl_error_messages.erm_id%TYPE,
sp_err_msg tbl_error_messages.erm_msg%TYPE
TYPE RCT1 IS REF CURSOR RETURN RT1;
END;
sho err
CREATE OR REPLACE PROCEDURE sp_dev_sel_all_devices (
in_usr_id IN tbl_user.usr_id%TYPE,
in_session_id IN tbl_user.usr_curr_session_id%TYPE,
RC1 IN OUT sp_dev_sel_all_devicesPKG.RCT1
) AS
ls_err_hint tbl_error_log.erl_err_hint%TYPE := 'BEGINING';
ls_err_code tbl_error_messages.erm_id%TYPE;
ls_err_msg tbl_error_messages.erm_msg%TYPE;
BEGIN
ls_err_hint := 'Check the timeout status of the user';
sp_utr_chk_timeout(UPPER(in_usr_id), in_session_id, 'sp_dev_sel_all_devices', ls_err_code, ls_err_msg);
ls_err_hint := 'Getting all Devices from tbl_device';
OPEN RC1 FOR
SELECT dev_id,
dev_name,
ls_err_code err_code,
ls_err_msg err_msg
FROM tbl_device
ORDER BY dev_name;
RETURN;
END;
sho err
Hope this works

George:
You can use CURSOR VARIABLE to pass this

create or replace package pkg_a
as
TYPE c_emp REF CURSOR;
PROCEDURE mysp (var1 IN NUMBER,
c_var2 OUT c_emp);
END package pkg_a;
CREATE OR REPLACE PACKAGE BODY pka_a
AS
PROCEDURE mysp (var1 IN NUMBER,
c_var2 OUT c_emp)
IS
BEGIN
OPEN c_var2
FOR
SELECT * FROM emp;
END mysp;

How to delete multiple rows from ADF table

How to delete multiple rows from ADF table

Hi,
best practices when deleting multiple rows is to do this on the business service, not the view layer for performance reasons. When you selected the rows to delete and press submit, then in a managed bean you access thetable instance (put a reference to a managed bean from the table "binding" property") and call getSeletedRowKeys. In JDeveloper 11g, ADF Faces returns the RowKeySet as a Set of List, where each list conatins the server side row key (e.g. oracle.jbo.Key) if you use ADF BC. Then you create a List (ArrayList) with this keys in it and call a method exposed on the business service (through a method activity in ADF) and pass the list as an argument. On the server side you then access the View Object that holds the data and find the row to delte by the keys in the list

Passing Multiple rows from one external webpart list to another

Hi Folks,
I have almost spent 1 week looking into this without any success. I have an external list "List A" (in a webpart) with one of the columns as "State".
Another external list "List B" (in a webpart ) has state and user as columns. In some case I want to pass 1 state and in another I want to pass multiple state. Passing one state from List A to List B works fine. But Multiple state does
not work because the webpart list has the property "Send First row to connected web parts when page loads". If I disable this option then the web part does not pass anything. Is there a way to pass multiple rows from one Webpart
external list to other?

No Lookups
Unfortunatly the only thing that you can do a look up on in an external list is on the ID column, anything else and you are out of luck.

How to select multiple rows from List Of Values

Hello,
I use ADF 11g to create my list of values (LOV). I want to select multiple rows from it. but i can't.
so how i can select many rows to set them in my adf table.
Thank in advance

Hi,
LOV is map to an attribute in the viewObject so it will return only one value or more values from selected row. You can't select multiple rows from LOV.
But you can do this by using popup which you can select multiple rows and insert the selected rows to another table.
This blog post explain how to achieve this :

Retruring Multiple rows from a Stored Procedure

The Oracle JDBC documentation shows how to return a cursor pointer through the parameter list of a stored procedure allowing a Java program to use the cursor like a normal result set. I've tried it (using the thin driver) and it works fine - however, I'm having trouble getting this to work running the program under a Weblogic server (using their own JDBC implementation). So, I have two questions:
1) Has anyone had this problem before and solved it ??
2) Are there any other techniques for getting multiple rows back from the database without having to fire "raw" sql at it ?

Hi
You could return not resultset but array, for example:
PACKAGE TEST:
type string_table is table of varchar2(80)
index by binary_integer;
function get_something (
something1 out string_table,
arraylength in number
) return number;
PACKAGE'S BODY:
function get_something (
something1 out string_table,
