Problem in fetching rows

Hi
I have a table which contains one foreign key(say function_id) and I made a composite primary key in my table which is the combination of two fields (say function_id,groups)..so I dont use any automatic generated id in this table..I did not have any problem in inserting the details...But I got a problem in updating the details..i.e I want to fetch the details(group,function_id)...the problem is that I got 'no data found error' while fetching...can anyone say what condition have I to give to fetch the details....
Thanks in advance

Problem in fetching row code...

Hi there,
I have a bit of a problem setting up automatic row processing. The Apex processing is causing an error, but I'm not sure what PL/SQL code is being run (obviously, I don't have access to the Apex code) and all I get is the error following:
0.03: Processing point: AFTER_HEADER
0.03: ...Process "Fetch Row from VMS2_VU_VEHICLE_DETAILS": DML_FETCH_ROW (AFTER_HEADER) F|#OWNER#:VMS2_VU_VEHICLE_DETAILS:P21_ID:ID
0.05: Show ERROR page...
0.05: Performing rollback...
0.05: Processing point: AFTER_ERROR_HEADER
and then the following exception report on the page:
ORA-06550: line 1, column 17: PL/SQL: ORA-00936: missing expression ORA-06550: line 1, column 9: PL/SQL: SQL Statement ignored
Can anyone tell me how I can diagnose the problem?
please ,
Thanks in Advance
Ahmed ,

Go to apex.oracle.com, use the Request a Workspace link, submit a request, wait for approval, then import your app into your workspace.
Create a table in your workspace schema using the SQL Workshop so that you can get the same error message when you run that form page that's giving you trouble.
When you get to that point, just tell me your workspace name and application ID.

Unable to fetch row opening form on table

Hi all,
i have a page with 2 regions, a form on table for DML and a report region that lists the same table.
I am trying to create records in the form and then recall them by report row link for changes.
I cant test if all that stuff can work because i when i run the page after first time an Unable to fetch row error is raised.
After that i have to logout and login and run the page again.
I do my best to explain the problem but feel free to ask for more.
Any kind of help or suggestions are welcome.
Thanks, Alex

Hi,
yes this is the problem.
When i run the page the first time it seem to work fine but after editing, just edit page and run again , the error is raised and the only way out is to logout apex.
My expectation was that if i run the page setting the rowid item , that is the pk of the tabular form, the region appear with setting for insert.

Fetch Row process error in form called from report

I have an interactive report that calls a form (when user hits the edit link on a row). The form is using a fetch row process (Automatic Row Processing). The problem I have is if a user tries to hit the edit link on a row that was already deleted, I get the 'No Data Found' error. I got around it by adding a condition (exists) to the fetch row process, but that just retirns a blank recor din the form. I wanted to either make a nice error (with a validation) etc. Anybody run into this?

Bob,
The easiest thing to do would be to have the page with the interactive report submit the page and you could use a validation on that page to run the check before redirecting the user to the form with a branch. To do this, however, as the interactive report only has "link" options, you'll need to use a little javascript in the query...
Example:
SELECT id,
'<span onclick="doSubmit(''' || id || ''')">Edit</span>' AS edit
FROM TABLERegards,

Problems deleting current row

Hello,
I have got the following problem. I have got a table with data from my database. And a dataprovider to fetch the data from my rowset. I have got a button in each row of this table where i can get details or delete the corresponding row.
But when i click delete he wont delete the row correct. After a while i realised that the always fetch the same row. I dont understand why because i took the same code as it was used in the tutorial. For control i made a variable to remember the id of the fetched row but it wont change after the first "delete". Can somebody tell me why he wont change the value?
public String l�schen_action() {
try {
RowKey rowKey = tableRowGroup1.getRowKey();
int id = getSessionBean1().getMaxappid().parseInt(applikationDataProvider.getValue("APPID", rowKey).toString(), 10);
getSessionBean1().setTemp(id);
if(rowKey != null && applikationDataProvider.canRemoveRow(rowKey)){
applikationDataProvider.removeRow(rowKey);
applikationDataProvider.commitChanges();
applikationDataProvider.refresh();
} catch (Exception e) {
log("Fehler beim L\366schen des Eintrags", e);
error("Exception deleting row: " + e);
} // end try catch
return null;
Thanks in advance for help

Try this and see if that helps

OnError in form: Error Unable to fetch row

Hello,
I'm trying to create such functionality, that in report "edit" link leads to form on another table. Everything is ok with rows, that exist in that table (i can edit them in form). But I want, that if row does not exist - the form should open the "Create record" window.
Now i get an error:
ORA-01403: no data found
Error Unable to fetch row.
Maybe some computation needs to be done for primary key?
Thanks.

I requested for workspace in apex.oracle.com, but i solved the problem sooner. I created one more column ir report (using the unique column left join), which was the primary key of the other table and included it into EDIT link.

How to fetch rows from PL/SQL table(Collections)

Hi,
I retrived rows from the table and stored in to table type.
Now I want fetch these rows and display on the screen. Pls guide me.
following code is my code:
DECLARE
type t1 is table of emp%rowtype index by binary_integer;
var1 t1;
v_counter number:=0;
BEGIN
select * bulk collect into var1 from emp;
for vr in var1.first..var1.last
loop
dbms_output.put_line(var1(1)); --Got an Error Here. Acually I don't Know how to fetch.
update dept set deptno=var1.deptno --Here also Error occured.
end loop;
END;

Fetching rows to display them is a task for the client tool. You need to define a ref cursor therefore.
If you just want to play around, here we go
SQL> DECLARE
2    type t1 is table of emp%rowtype index by binary_integer;
3    var1 t1;
4    v_counter number:=0;
5 BEGIN
6    select * bulk collect into var1 from emp;
7    for vr in 1..var1.count loop
8      dbms_output.put_line(var1(vr).ename);
9      update dept set deptno=var1.deptno Here also Error occured.
10    end loop;
11 END;

Problem when fetching a VO

Hi,
I am facing a problem when fetching a VO. Actually i am having a field which is of type MessageTextInput. This field has a initial value set to 1 which is taken from the database. In the page i change the value to that field to 5(say). But when i am fetching the vo which this field is resided, I am getting value 1 only not 5 which i changed. I know it will take the value from database itself, but i want to fetch 5. How is this possible. Please any one help me out in this issue.
Thanks in Advance.

are you taking the instance of the OAMesaageTextInputBean in ur CO.
You need to take the instance and then get the entered value. Only then you will be able to see the updated value (5)
Let me know for any other help and if it doesn't resolve ur problem, Please provide some more information on it.
Thanks

netui-data:pager action to dynamically fetch rows

Hi,
How can I configure a data grid pager to dynamically fetch new rows when a user swap pages through the pager?
I know I can fetch all my rows to a collection / array before rendering the datagrid and set the pager to iterate over it like this:
[Controller]
private List<Ride> rides;
public List<Ride> getRides() {
     return rides;
[Action]
rides = rideDBControl.getAllRides(); // huge amount of data
return forward;
[JSP]
     <div style="border-width:2px;"><netui-data:dataGrid name="currentRidesGrid" dataSource="pageFlow.rides">
          <netui-data:configurePager pagerFormat="prevNext" pageSize="${pageSize}" />
          <netui-data:header>
               <netui-data:headerCell headerText="Name" />
               <netui-data:headerCell headerText="Description" />
          </netui-data:header>
          <netui-data:rows>
               <netui-data:spanCell value="${container.item.name}" style="background-color: #f0f0f0;font-size:14pt;">
               </netui-data:spanCell>
               <netui-data:spanCell value="${container.item.description}">
               </netui-data:spanCell>
          </netui-data:rows>
     </netui-data:dataGrid></div>
But how can I make the pager call a method to update the contents of the collection "rides" according to the current selected page and page size? And how can I obtain the current page and page size inside that method?
I want to paginate queries that may return a huge amount of data (1m + rows), so, fetching all rows at once is impracticable. What I want to do is propagate the current page and page size from the pager to a method that will update the current collection according to a query such as:
Select X, Y, Z
From Table
Where ...
And ROWNUM BETWEEN page * pageSize AND (page + 1) * pageSize
Can anyone help a noob?

For further reference I've found the answer by myself.
To dynamically fetch rows you need to modify the <netui-data:configurePager> tag and include both a pageAction and partialDataSet attributes, e.g.:
<netui-data:configurePager pagerFormat="prevNext" pageSize="${pageSize}" pageAction="pagination" partialDataSet="true" />
Within the pagination action you can obtain the current row and page size from a PagerModel object. You can then update the dataSource (just remember to call the setDataSetSize providing the length of the full dataset so that the pager displays the correct amount of pages), e.g.:
@Jpf.Action(forwards = { @Jpf.Forward(name = "success", navigateTo = Jpf.NavigateTo.currentPage) })
     public Forward pagination() {
          DataGridStateFactory dataGridStateFactory = DataGridStateFactory
                    .getInstance(getRequest());
// Gets the pagerModel object for the grid
          PagerModel pagerModel = dataGridStateFactory.getDataGridState(
                    "currentRidesGrid").getPagerModel();
// => Code to get the entire dataSource size <=
          pagerModel.setDataSetSize(dataSourceSize);
          // Obtain the first row and page size from the model
          int firstRow = pagerModel.getRow();
          int pageSize = pagerModel.getPageSize();
          // => Code to fetch the rows to be displayed <=
          rides = pageRides;
          Forward forward = new Forward("success");
          return forward;
I hope this helps.

How to fetch rows from a table like search engines do?

Is it possible to fetch rows from a table like Google does? I want to fetch row number 20-40 after the select has ordered the rows.
Pseudo code: select * from log where rownum > 20 and rownum < 40 order by date;
Rownum doesn't work with ordering so I tried:
select * from log where (select * from log order by date) and rownum <20;
But that still doesn't do what I want. I get the "top 20" rows but I can't get rows 20-40.
My real table has 70000 rows and I want to select 69000-70000 so I really need a SQL do fetch only the rows I need.
Any help would be very appreciated!
Best regards,

SELECT alias_for_rownum, column_names
        FROM   (SELECT ROWNUM AS alias_for_rownum, column_names
                FROM   (SELECT   column_names
                        FROM     table_name
                        ORDER BY columns_to_order_by)
                WHERE ROWNUM <= last_row_you_want)
        WHERE alias_for_rownum >= first_row_you_want
Example:
-- (This example uses the Oracle dept demo table.
SET AUTOTRACE ON EXPLAIN
SELECT rn, deptno, dname, loc
        FROM   (SELECT ROWNUM AS rn, deptno, dname, loc
                FROM   (SELECT   deptno, dname, loc
                        FROM     dept
                        ORDER BY deptno)
                WHERE ROWNUM <= 3)
        WHERE rn >= 2
                RN     DEPTNO DNAME          LOC
                 2         20 RESEARCH       DALLAS
