Fetch rows automatically

Hi,
got a select list containing the columns of emp and element all_columns, a textfield for the search string , a go button
and a sql report which will filter the report through selected column and search string.
How can the report be displayed (select list with all_columns) by entering the page, without pressing the go button ?

Thanks - I had read the documentation before, but interpreted it differently.
What I had read was in:
http://download-east.oracle.com/docs/cd/B19306_01/appdev.102/b14261/sqloperations.htm#i45288
The extract of interest was:
Opening a Cursor
Opening the cursor executes the query and identifies the result set, which consists of all rows that meet the query search criteria. For cursors declared using the FOR UPDATE clause, the OPEN statement also locks those rows. An example of the OPEN statement follows:
DECLARE
CURSOR c1 IS SELECT employee_id, last_name, job_id, salary FROM employees
WHERE salary > 2000;
BEGIN
OPEN C1;
Rows in the result set are retrieved by the FETCH statement, not when the OPEN statement is executed.
My interpretation was that the result of the query was put into the temporary tablespace and then retrieved into the program during the FETCH.
Assuming I was wrong, what I'm wondering now is how I can possibly be running out of temporary space during this OPEN cursor process.

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.

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,

Playing videos in a row automatically?

I guess you can't do this in fornt row, but I was wondering if it is possible to play quick time movies in a row automatically, without having to go and click play on the next movie everytime one ends.
By the way, if anyone knows how to do this in front row, you are a godsend!
THANKS!

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.

VO CONTAINS ALL THE DB ROWS AUTOMATICALLY WITHOUT ANY QUERY EXECUTION

HI ALL,
I am getting a strange issue. I have two VO say UserVO and PasswordVO.
When i run the application i am not using any BC component in HomePg. I click on login and through another read only VO i am authenticating.
After authentication i am doing getUserVO() and in WATCH i can see fetched row count and row count showing all the rows from DB. This View Object has not been executed before and still it shows all the rows.
Now when i apply a view criteria into it and execute the query still it contains all the rows. Its not filtering it.
Also, i have overridden executeQuery and executeQueryForCollection methods and i have put debug points there.
It comes there only when i am explicitly executing the query after applying view criteria.
Please let me know if i am doing something wrong.
Thanks,
Deepak

Thanks Timo for a quick reply.
a) I am using JDEV 11G Release 1 (11.1.1.6.0)
b) Also i am specify the following two parameters in java options and still logs are not coming up in console:
-Djbo.debugoutput=console -Djps.app.credential.overwrite.allowed=true
c) "The framework executes vo in the background using the default query."
Does that mean framework doesn`t internally call executeQuery to get rows from DB and executes the query some other way.
As i have break point and its not coming there at all.
Please advise.
Thanks,
Deepak

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;

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.
Cheers

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,
Christer Nordvik

Set Item after Fetch Row

Hi,
i have an item in a form region with 'Display As': 'Text
Field (Disabled, saves state)'. This item is populated by the 'Fetch
row' process. After the fetch row process i want to set the item by
the process 'Set Data' (Process Point: On Load - After Footer) to
another value - but it doesn't work.
In Debug Mode i get the following messages:
0.05: Processing point: AFTER_FOOTER
0.05: ...Process "Set Data": PLSQL (AFTER_FOOTER) BEGIN :P50_MARKE := #OWNER#.wav_api.getData ......
0.05: ...Session State "P50_MARKE" - saving same value: "Walther_____"
The value from the fetch was: 'Walther' and after setting it should be 'Walther_____'
As you can see my function wav_api.getData works fine.
Has somebody an idea what's wrong?
Best regards,
Marti

Martin,
Your stated requirement is: "After the fetch row process i want to set the item..."
Your process does this and your computation does this. They both set the item's value in session state as your debug output showed. But doing either of these at the After Footer point makes no sense. That's after the item has been rendered on the page as a form input item. And that's the value that will be POSTed in the form and which will then override the value in session state that your process or computation established.
Andy's suggestion was to use a Post Calculation Computation. This is a property of the item (see the Source section). You would not need a computation or process on the page if you do it this way.
Another method would be to use an After-Header process or computation. For this to work, you would also need to change the item's Source Used setting to "Only, ..." from "Always, ...". If you do it that way and the process or computation always sets the value correctly then that should be all you need to do. If the process or computation runs conditionally or cannot be relied upon to set the correct value then you may need to add other logic to the page.

Unable to fetch row...No data found

Hello,
After table being truncated, and new data set being inserted in that table, I'm getting the following error message 'no data found...unable to fetch row' . Data was getting fetched in the form by the primary key with the original data set in the table, but after truncate/insert, it is no longer working.
Any idea why?

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.

'Fetched Rows' refresh issue

When freezing views for several tables, the 'Fetched Rows' value is always the last updated value, not the correct one in the current context.
In the case of finding the total number of rows there is a workaround - to select from the popup menu Table > Count rows, but then, why display an incorrect value ?
And on the same 'count rows' topic, why do I need to further press the 'Apply' button in order to get the rows numbered ?
Tudor

You are right - the last fetch performed by Raptor/SQL Developer updates the fetch count on the status bar (this includes things like querying the columns when displaying a table tab).
I have suggested previously that we have the fetch count displayed next to the query execution time on the SQL Worksheet, but haven't had any positive response.
There doesn't appear to be enough room on the data tab for this to be displayed in the same place when querying table/view data from the table/view tab.
As for the 'Count Rows' needing Apply - even if you don't want to, you are given the option of copying the query that is being used for the Count Rows (not that I think this means we should have the two step process for counting rows).
