How to show multiple records in JDeveloper automatically

Hi, you guys,
May I ask you how to show multiple records, say consecutive three records, of a View object in JDeveloper?
I know that we can just drag and drop a view object as a child (Table) of a scrollPane.
Are there any other approaches?
Thanks a lot for your time.

Thanks for your reply.
You are right.
Table binding is the best solution for that.
But in my mind, a record in a table is always shown in one row (or one line), am I right?
If so, it is not convient to show records with multitple columns.
Let's say, there are 20 columns to show for each record. Then we should display a record in, say 3 lines.
How can we do that?
Are there any suggestions?
I am thinking that maybe I can use secondary row set iterators for that since we can create two or more row set iterators for the same view object.
Assume I want to show three consecutive records. I can use attribute binding to show the current record in three lines by dragging attributes one by one from Data Control Palette to Design Window as Child | TextField;
But I do not know how to use a secondary row set iterator for the next record. Where shall I create a secondary row set ietrator such that I can use it to create and synchronize the bindings.
Thanks a lot

How to show multipe records on a single record

Hi all,
I have a query which can contain 1 or Many records for each S.WAS_NO or APPL_NO even. A new record is created when the APPL_STATUS changes and a timestamp is created in APPL_STATUS_CHANGE_DATE.
select distinct
       S.APPL_ID,
       S.WAS_NO,
       S.AS_STATUS,
       S.STATUS_CHANGE_DATE,
       dense_rank() over (partition by S.WAS_NO order by S.STATUS_CHANGE_DATE) rank
from table_a S, table b S2
where S.APPL_ID = S2.APPL_ID
order by S.WAS_NO, rank asc;
Current Results:
APPL_ID---WAS_NO---------------AS_STATUS----STATUS_CHANGE_DATE-----RANK
6628-------E4G0YL9B08V0V6---ASSIGNED-------25/10/2011----------------------1
6628-------E4G0YL9B08V0V6---USED--------------30/12/2011----------------------2
Desired Results:
APPL_ID--WAS_NO------------------AS_STATUS1----STATUS_CHANGE_DATE1----AS_STATUS2----STATUS_CHANGE_DATE2
6628-------E4G0YL9B08V0V6----ASSIGNED---------25/10/2011------------------------USED--------------30/12/2011The rank is based on the WAS_Number and ordered by the STATUS_CHANGE_DATE so i know which order they should go in.
I want to show 1 record per WAS_NO and show each status change with its date. There can only be a maximum of three status changes.
I have not been able to workout how to get Multiple records onto a singe record and in different columns.
Many thanks

This should do what you want:
WITH t AS
(SELECT 6628 appl_id, 'E4G0YL9B08V0V6' was_no, 'ASSIGNED' as_status, TO_DATE('25/10/2011', 'DD/MM/YYYY') status_change_date FROM dual UNION ALL
SELECT 6628 appl_id, 'E4G0YL9B08V0V6' was_no, 'USED' as_status, TO_DATE('30/12/2011', 'DD/MM/YYYY') status_change_date FROM dual UNION ALL
SELECT 6628 appl_id, 'E4G0YL9B08V0V6' was_no, 'COMPLETE' as_status, TO_DATE('15/01/2012', 'DD/MM/YYYY') status_change_date FROM dual UNION ALL
SELECT 6629 appl_id, 'A5AAFG1C07L0P2' was_no, 'ASSIGNED' as_status, TO_DATE('19/01/2012', 'DD/MM/YYYY') status_change_date FROM dual)
SELECT   appl_id,
         was_no,
         MAX(CASE rank
         WHEN 1 THEN as_status
         ELSE NULL
         END) as_status1,
         MAX(CASE rank
         WHEN 1 THEN status_change_date
         ELSE NULL
         END) status_change_date1,
         MAX(CASE rank
         WHEN 2 THEN as_status
         ELSE NULL
         END) as_status2,
         MAX(CASE rank
         WHEN 2 THEN status_change_date
         ELSE NULL
         END) status_change_date2,
         MAX(CASE rank
         WHEN 3 THEN as_status
         ELSE NULL
         END) as_status3,
         MAX(CASE rank
         WHEN 3 THEN status_change_date
         ELSE NULL
         END) status_change_date3
FROM    (SELECT appl_id,
                was_no,
                as_status,
                status_change_date,
                DENSE_RANK() OVER (PARTITION BY was_no ORDER BY status_change_date) rank

How to Save Multiple Records In Data Block

Hi All,
I Have Two Blocks --> Control Block,Database Block
Please Any Idea How to Save Multiple Records In Data Block when User changed Data in Control Block.
Thanks For Your Help
Sa

Now i have to use each record of control block(ctl_blk) as where condition in data base block(dat_blk)and display 10 records from database table.>
Do you want this coordination to be automatic/synchronized or only when the user clicks a button or something else to signal the coordination? Your answer here will dicate which trigger to put your code in.
As to the coordination part, as the user selects a record in the Control Block (CB), you will need to take the Key information and modify the Data Block's (DB) "DEFAULT_WHER E" block property. The logical place to put this code is the CB When-New-Record-Instance (WNRI) trigger. You code will look something like the following:
/* Sample WNRI trigger */
/* This sample assumes you do not have a default value in the BLOCK WHER E property */
DECLARE
   v_tmp_dw    VARCHAR2(250);
BEGIN
   v_tmp_dw := ' DB_Key_Column1 = '||:CONTROL.Key_Column1||' AND DB_Key_Column2 = '||:CONTROL.Key_Column_2;
   Set_Block_Property('DATA_BLOCK', DEFAULT_WHER E, v_tmp_df);
   /* If you want auto coordination to occur, do the following */
   Go_Block('DATA_BLOCK');
   Execute_Query;
   /* Now, return to the Control Block */
   Go_Block('CONTROL_BLOCK');
END;
The Control block items are assigned with values in Form level (Key_exeqry).If your CD is populated from a single table, it would be better to create a Master - Detail relationship (as Abdetu) describes.
Hope this helps,

How to pass multiple records to target side using xquery

Hi Everybody,
I am using xquery transformation.
Input: Source payload contains 5 variables.
Target payload contains 5 variables.
I have input with payload with multiple instance like:
<Input>
<payload1>
<a>1<a>
<b>2<b>
<c>3<c>
<d>4<d>
<e>5<e>
</payload1>
<payload1>
<a>6<a>

But while testing with multiple line items,i am getting an error as follows.
*Error executing the XQuery transformation: line 14, column 17: {err}FORG0005: expected exactly one item, got 2+ items*
So please provide me the steps how to pass multiple records to target side using xquery.
Regards,
Jyoti Nayak

Hi Jyoti Nayak,
You have to do something like the example bellow, you can not just repeat the inner element, you will need an outer "container" tag. So you will have to change the target element of your xq transformation.
declare function xf:setToList($set1 as element(ns0:set))
as element(ns0:list) {
<ns0:list>
for $pair in $set1/ns0:pair
return
<ns0:entry>
<ns0:key>{ data($pair/ns0:key) }</ns0:key>
<ns0:value>{ data($pair/ns0:value) }</ns0:value>
</ns0:entry>
</ns0:list>
Cheers,
Vlad

Hi,
Am facing the same issue stated above that I couldnt get all the records in the table that am querying in the Proxyservice.
For example:
fn-bea:execute-sql('EsbDataSource', 'student', 'select Name from StudentList' ) is the query that am using to fetch the records from the table called StudentList which contains more than one records like
Id Name
01 XXX
02 YYY

I tried to assign the result of the above query in a variable and while trying to log the variable, I can see the below
<student>
<Name>XXX</Name>
</student>
I want to have all the records from my table in xml format but it's not coming up. I get the value only from the first row of my table.
Please suggest.

-Sandip

Rashmi/Kukku,
First of all, Thanks for your help!
Is there any other way in which we can access tables other than using BAPIs or RFCs?
In my case, there is a table structure which has to be updated with values after validating a key. i don't think there is any RFC available now. do i need to create bapi/rfc for that?

How to select multiple records in the ALV POP UP by using oops

Hi All,
We have a requirement of ALV POP UP by using the OOPS. How to select the multiple records in the POP UP and After selecting that i want do Inteactive ALV means again one more POP UP in ALV.
Thanks for help....
Regards,
Bharani

Hello Bharani
Displaying an ALV list in a popup is by no means different from a list displayed on a main screen. The only thing you need to consider is that you set the right screen level when creating the parent container for the ALV.
For more details refer to thread in CL_GUI_SPLITTER_CONTAINER ALV list is not show in called screen
" step 1:
CREATE OBJECT gr_spliter
    EXPORTING
      parent = cl_gui_container=>screen0 " For first popup use: =>screen1
      rows = 1
      columns = 2.

How to show all records by default on search result page?

Hi
I am trying to make a search page that would execute the search in the database based on one or more field constraints.
(Using MySQL,PHP)
I have 2 columns in the database "vm_ip" (primary key) <IP address>, "Operating_System" <Any, Windows, Solaris, AIX>
need to search vm_ip based on other two fields.
PROBLEM: Need to show all the record when I select "Any" in the Operating_System drop down menu.
<p>Operating System:
    <select name="os_select" id="os_select">
    <?php
$os_count=1;
foreach($os_type as $value) //(os_type is array with possible values of OS)
echo "<option value=".$os_count.">".$value."</option>";
    $os_count++;
?>
      <option value=" " selected="selected">Any</option>
    </select>
</p>
this code POSts NULL value to the search page.
Below code is of recordset on search page
$varOS_virtual = "Operating_System"; // recordset variable set to same as column name (default value)
if (isset($_POST['os_select'])) //this should not be true
$varOS_virtual = $_POST['os_select'];
mysql_select_db($database_xyz_db, $xyz_db);
$query_virtual = sprintf("SELECT table.VM_IP FROM table
WHERE table.Operating_System=%s", GetSQLValueString($varOS_virtual, "int"));
$virtual = mysql_query($query_virtual, $xyz_db) or die(mysql_error());
$row_virtual = mysql_fetch_assoc($virtual);
$totalRows_virtual = mysql_num_rows($virtual);
I expected the 'os_select' field to be null and default value of Operating_System to be "Operating_System" so that the Query shows all records.
But instead the value being passed in the Query is "0". and no records are shown.
What can I do to show all records?
As probably obvious I am new to php/MySQL so all the help is most welcomed .
Thanks

Hi
Thanks for the prompt reply but this does not solve my problem.
First thing I appologise for giving you incorrect info. Actually I have many more constraints on the search apart from OS.
Didn't think I would get single constraint specific ans.
Here is what all i tried and problems I faced:
1. I cannot use seperate queries cause I have around 7-8 other constraints on the search.
2. I cannot play around with the Record set code. For some reason even if I mess with it a little bit Dreamweaver stops recognising the recordset. for eg i tried the below code:
$query_virtual = sprintf("SELECT table.VM_IP FROM table WHERE
table.Operating_System=%s ,($_POST['os_select']=="")? TRUE:GetSQLValueString($varOS_virtual, "int"));
this ran well for the first time, and then the record set was screwed up. kept on asking me to "Discover" the links, which it couldn't do.
3. take a look at this code:
$varOS_virtual = "Operating_System";
if (isset($_POST['os_select'])) {
$varOS_virtual = $_POST['os_select'];
$varState_virtual = "State";               //second constraint
if (isset($_POST['state_select'])) {
$varState_virtual = $_POST['state_select'];
mysql_select_db($database_xyz, $xyz);
$query_virtual = sprintf("SELECT table.VM_IP FROM table AND table.Operating_System=%s AND State=%s",
GetSQLValueString($varOS_virtual, "int"),GetSQLValueString($varState_virtual, "int"));
$virtual = mysql_query($query_virtual, $xyz) or die(mysql_error());
$row_virtual = mysql_fetch_assoc($virtual);
$totalRows_virtual = mysql_num_rows($virtual);
here on passing NULL value for "Any" GetSQLValueString($varOS_virtual, "int") functions returns NULL and though the Default value of
varOS is set to 'Operating_System" query takes NULL value only which when executed shows no records.
My problem majorly revolves around how to put something like "WHERE Operating_System= Operating_System" OR "WHERE Operating_System= TRUE" in the query, when passed through variable they are sent as Strings or NULL.
Thats why WHERE 1=1 also doesnt work, because it has "WHERE Operating_System= NULL" in AND.
Logically when NULL is passed default value of variable should comeinto picture, but tha isnt happening.
Thanks again for answering. hope I was able to explain my problem.

How to handle multiple records in BPMN process

Hi All,
We are using Oracle BPM 11g.In my requirement,I am using the database adapter to get the data from table and I need to validate the each record and update the status of that record from the BPM Process.But I dont know how to handle if multiple records come at a time.Can anybody please helpout from this problem.
Thanks in advanced.
Narasimha Rao.

Can you have a look at this post: http://redstack.wordpress.com/2010/09/30/iteratingtraversing-arrays-in-bpm/
It's solving a different problem, but the key is that it's using a multi-instance subprocess to iterate over an array of "things" that need to be acted in. In your case it's the set of results from the db query rather than the set of tests in the example. But the principle is the same. You'd take collection of rows from the DB and process them in a multi-instance subprocess. The text that begins with the following would be good place to start:
"Now let’s implement the body of our process. We will use the Subprocess object to handle the traversal of the array of tests. Drag a Subprocess from the component palette on the right into the process and drop it on the line between the Start and End nodes."
In the loop characteristics you'd define whether you want to execute serially or in parallel.

How to show multiple messages for a single exception

hi
Please consider this example application created using JDeveloper 11.1.1.3.0
at http://www.consideringred.com/files/oracle/2010/MultipleMessagesExceptionApp-v0.01.zip
It has a class extending DCErrorHandlerImpl configured as ErrorHandlerClass in DataBindings.cpx .
Running the page and entering a value starting with "err" will result in an exception being thrown and multiple messages shown.
See the screencast at http://screencast.com/t/zOmEOzP4jmQ
To get multiple messages for a single exception the MyDCErrorHandler class is implemented like
public class MyDCErrorHandler
extends DCErrorHandlerImpl
public MyDCErrorHandler()
    super(true);
@Override
public void reportException(DCBindingContainer pDCBindingContainer,
    Exception pException)
    if (pException instanceof JboException)
      Throwable vCause = pException.getCause();
      if (vCause instanceof MyMultiMessageException)
        reportMyMultiMessageException(pDCBindingContainer,
          (MyMultiMessageException)vCause);
        return;
    super.reportException(pDCBindingContainer, pException);
public void reportMyMultiMessageException(DCBindingContainer pDCBindingContainer,
    MyMultiMessageException pException)
    String vMessage = pException.getMessage();
    reportException(pDCBindingContainer, new Exception(vMessage));
    List<String> vMessages = pException.getMessages();
    for (String vOneMessage : vMessages)
      reportException(pDCBindingContainer, new Exception(vOneMessage));
}I wonder if calling reportException() multiple times is really the way to go here?
question:
- (q1) What would be the preferred use of the DCErrorHandlerImpl API to show multiple messages for a single exception?
many thanks
Jan Vervecken

fyi
Looks like using MultipleMessagesExceptionApp-v0.01.zip in JDeveloper 11.1.1.2.0 (11.1.1.2.36.55.36) results in a different behaviour compared to when used in JDeveloper 11.1.1.3.0 (11.1.1.3.37.56.60)
see http://www.consideringred.com/files/oracle/img/2010/MultipleMessages-111130versus111120.png
When using JDeveloper 11.1.1.2.0 each exception seems to result in two messages where there is only one message (as intended/expected) per exception when using JDeveloper 11.1.1.3.0 .
(Could be somehow related to the question in forum thread "multiple callbacks to DCErrorHandlerImpl".)
But, question (q1) remains and is still about JDeveloper 11.1.1.3.0 .

Jan

I want to show an output to combine all medication records of one person into one, and I created a function.
CREATE OR REPLACE FUNCTION COMMEDICATION(p_subjectid IN immunodata.medication.subjectid%TYPE ) RETURN VARCHAR2 IS
v_medication VARCHAR2(1000);
BEGIN
FOR c IN (SELECT THEDATE, MED_PAGENOTCOMPLETED, MEDICATION_NAME, MEDICATION_CLASSIFICATION, MEDICATION_DOSENUM, MEDICATION_DOSEMEASURE,MEDICATION_ROUTE,MEDICATION_FREQ,MEDICATION_BEGIN,MEDICATION_END,DATASOURCE,NOCHANGE FROM immunodata.medication WHERE subjectid = p_subjectid)
LOOP
IF v_medication IS NULL THEN
v_medication := c.THEDATE||' '||c.MED_PAGENOTCOMPLETED||' '||c.MEDICATION_NAME||' '||c.MEDICATION_CLASSIFICATION||' '||c.MEDICATION_DOSENUM||' '||c.MEDICATION_DOSEMEASURE||' '||c.MEDICATION_ROUTE||' '||c.MEDICATION_FREQ||' '||c.MEDICATION_BEGIN||' '||c.MEDICATION_END||' '||c.DATASOURCE||' '||c.NOCHANGE;
ELSE
v_medication := v_medication||','||c.THEDATE||' '||c.MED_PAGENOTCOMPLETED||' '||c.MEDICATION_NAME||' '||c.MEDICATION_CLASSIFICATION||' '||c.MEDICATION_DOSENUM||' '||c.MEDICATION_DOSEMEASURE||' '||c.MEDICATION_ROUTE||' '||c.MEDICATION_FREQ||' '||c.MEDICATION_BEGIN||' '||c.MEDICATION_END||' '||c.DATASOURCE||' '||c.NOCHANGE;
END IF;
END LOOP;
RETURN v_medication;
END;
and I performed this selection statement:
SQL> select subjectid, barcode, COMmedication(subjectid) from immunodata.demographics where barcode=500135;
SUBJECTID BARCODE
COMMEDICATION(SUBJECTID)
33 500135
15-SEP-00 Cyclophosphamide Immunosuppresant .7 MG IV MONTLY FORM1 ,15-SEP-00 Hydroxychloroquine (Plaquenil) Immunosuppresant 400 MG DAILY FORM1
It is exactly what I need， so I want to show all records in the tables.
SQL> select subjectid, barcode, COMmedication(subjectid) from immunodata.demographics;
ERROR:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at "SYS.COMMEDICATION", line 9
no rows selected
It seems that one record could be shown, but multiple could not.
Is there anything wrong with my code or other things?
Thanks!

It seems that one record could be shown, but multiple could not.
Is there anything wrong with my code or other things?
It means that there is at least one subjectid in your table for which the value of v_medication in the function exceeds 1000 characters.
You may want to increase the size of v_medication to 4000, which would be the upper limit for the function's return value.
