Weird behavior when deleting too many rows from a table

Hello ADFr's
I have the following code in my managed bean which removes data from an adf table. I am getting an id set from a calling process in my app.
DCIteratorBinding tableIterato = getIterator(); // returns iterator of the table being modified
RowSetIterator rsi = tableIterator.getRowSetIterator();
for(Integer id : idSet) {
Key key = new Key(new Object[]{id.toString()});
Row foundRow = rsi.findByKey(key, 1)[0];
foundRow.remove();
My issue ..
This seems to work when the idSet is small 30 or so. But when the idSet is like 50(maybe a littel less) or more, none of the rows seem to be getting deleted. Any clue?
I added this test in there to see if any rows were being deleted after the loop above, and all the records were still being printed out.
for(Row row : tableIterator.getAllRowsInRange()) {
System.out.println("row with name " row.getAtribute("name") " swtill exists");
This seems to work under 30 fine.
Why doesn't this work for any size idSet?

That was it.. thanks Puthanampatti.
I thought about this right after I sent this//
Well maybe this post will help someone else (-;

Can you have too many rows in a table?

How many rows would you consider to be too many for a single table and how would you re-arrange the data if
asked?
any answers?

I have some tables with over 100 million rows that still perform well, and I'm sure much larger tables are possible. The exact number of rows would vary significantly depending on a number of factors including:
Power of the underlying hardware
Use of the table – frequency of queries and updates
Number of columns and data types of the columns
Number of indexes
Ultimately the answer probably comes down to performance – if queries, updates, inserts, index rebuilds, backups, etc. all perform well, then you do not yet have too many rows.
The best way to rearrange the data would be horizontal partitioning. It distributes the rows into multiple files; which provides a number of advantages including the potential to perform well with larger number of rows.

Easy Question:Select many rows from a table and execute BAPI for these rows

Hi Experts,
I have created one WD project. The WD project fetches some records of backend using BAPI and displays in a table. I have to select some rows from the table and then execute BAPI for selected rows.
How I can select multiple records from the table and then execute another BAPI for selected rows.
Regards,
Gary

Hi,
In the Node which you binded to the table create one more attribute of type boolean.
For example your node is as below:
//Table Node
TableNode
> Att1
> Att2
> isSelected(boolean) - Newly created attribute for this requirement.
//Result Node contains the elements selected in TableNode
ResultNode
>Att1
>Att2
Now in the table create one more Column with Checkbox as tablecell editor. Now bind this boolean attribute to that check box.
Now in the code you can get the selected rows by user as below:
for(int i=0;i<TableNode().size();i++)
if(wdContext.nodeTableNode().getTableNodeElementAt(i).getIsSelected()==true)
    IPrivateTestView.IResultNode element=wdContext.createResultNodeElement();
    element.setAtt1(wdContext.nodeTableNode().getTableNodeElementAt(i).getAtt1());
    element.setAtt2(wdContext.nodeTableNode().getTableNodeElementAt(i).getAtt2());
   wdContext.nodeResultNode().addElement(element);

My goal is to delete employee records for those employee which contains multiple values for JOB_NO
equal to 8181, (JOB_NO= 8181) with new start_dateS.
We need to keep only one record for JOB_NO 8181 which contains oldest start_date.
Here is the delete statement for the single record.
delete from emp
where empno = 7777 and job_no = 8181 and start_date in ('03/01/2002','06/24/1996);
So how could I delete thousands records from the table with this logic?
After deleting multiple records table should be as below:
select * from emp;
EMPNO--------DIVISION--------JOB_NO---------START_DATE

Here's one way to do it. I think this fits your business rules. At least it matches the output for your first example. It uses an analytic. I just like using them.

Cannot delete newly inserted row from a table

Dear all,
There is a table where I have just inserted a new record. I can do a select query on that record and even update it. However when I try to delete the record, my session hangs and the record does not gets deleted. I also do not get a error message.
Does anyone knows what the problem could be ?
Thanks in advance

How to delete the committed row from a table from its VOImpl class ??

I am new to ADF and I have problem to solve. To perform roll back I am using fetching key before roll back and setting it after undo operation, so that I can stay back in the currently selected row. But in my case I am using application model commit for one LOV attribute selection in the row. So when ever I am performing roll back operation after inserting a row, the values other than this committed LOV attribute gets roll backed, but I need remove the entire row from table. Does there any option to remove a row based on the attribute values of a row from VO's row implementation or from bean class in a performance optimized way ?
Thanks in advance..........

Why did you mark it answered but gave no dukes to finalight? That's not how it works.
You should mark his answer as correct and give him at least one duke, for the effort!

Copying many rows from one table to another

Could anyone tell me the best way to copy many rows (~1,000,000) from one table to another?
I have supplied a snipit of code that is currently being used in our application. I know that this is probably the slowest method to copy the data, but I am not sure what the best way is to proceed. I was thinking that using BULK COLLECT would be better, but I do not know what would happen to the ROLLBACK segment if I did this. Also, should I look at disabling the indexes while the copy is taking place, and then re-enable them after it is complete?
Sample of code currently being used:
PROCEDURE Save_Data
IS
CURSOR SCursor IS
SELECT     ROWID Row_ID
FROM     TMP_SALES_SUMR tmp
WHERE NOT EXISTS
(SELECT 1
     FROM SALES_SUMR
     WHERE sales_ord_no = tmp.sales_ord_no
     AND cat_no = tmp.cat_no
     AND cost_method_cd = tmp.cost_method_cd);
BEGIN
FOR SaveRec IN SCursor LOOP
INSERT INTO SALES_ORD_COST_SUMR
SELECT *
FROM TMP_SALES_ORD_COST_SUMR
WHERE ROWID = SaveRec.Row_ID;
RowCountCommit(); -- Performs a Commit for every xxxx rows
END LOOP;
COMMIT;
EXCEPTION
END Save_Data;
This type of logic is used to copy data for about 8 different tables, each containing approximately 1,000,000 rows of data.

Your best bet is
Insert into SALES_ORD_COST_SUMR
select * from TMP_SALES_ORD_COST_SUMR;
commit;

How to delete a selected row from adf table

Hi
I am using a ADF Table to get data from the database, i need to select a specific row and then delete it how to get
this done.
Thanks in Advance.

Or try this code:
In your backing bean:
    public void deleteRows(ActionEvent actionEvent) {
        ((AppModuleImpl)getApplicationModuleForDataControl()).deleteRowEmp();
    public static Object resolveExpression(String expression)
            try
                FacesContext facesContext = FacesContext.getCurrentInstance();
                Application app = facesContext.getApplication();
                ExpressionFactory elFactory = app.getExpressionFactory();
                ELContext elContext = facesContext.getELContext();
                ValueExpression valueExp =
                    elFactory.createValueExpression(elContext, expression, Object.class);
                return valueExp.getValue(elContext);
            catch (Exception e)
               ;// log you message here
            return null;
         * Get application module for an application module data control by name.
         * @param name application module data control name
         * @return ApplicationModule
        public static ApplicationModule getApplicationModuleForDataControl()
            return (ApplicationModule) resolveExpression("#{data.AppModuleDataControl.dataProvider}");
        }In your AppmoduleImpl:
    public void deleteRowEmp(){
        this.getEmpView1().removeCurrentRow();
        this.getDBTransaction().commit();
    }And another option is to expose the appmodule method as a client and bind to the jspx as a button.

How to delete the duplicate rows from the table

Hi,
I have 2 tbales namely component, component_audit
For each record in component table there are multiple entries in component_audit table.
I need to keep the first record and delete the others from the component_audit table
say for example
select a.component_id,a.dt_ti_stamp,a.component_name,a.column_before,b.comments from component_audit a,component b where a.component_id=b.component_id
( on the above result set only I shold apply the actual delete query )
PLease help me in this regards.
Thanks.

delete from component_audit a where dt_ti_stamp not in (select
                                        min(b.dt_ti_stamp)
                                   from
                                        component_audit b
                                   where
                                        a.component_id = b.component_id)

Delete 50 Million records from a table with 60 Million records

Hi,
I'm using oracle9.2.0.7 on win2k3 32bit.
I need to delete 50M rows from a table that contains 60M records. This db was just passed on to me. I tried to use the delete statement but it takes too long. After reading the articles and forums, the best way to delete that many records from a table is to create a temp table, transfer the data needed to the temp table, drop the big table then rename temp table to big table. But the key here is in creating an exact replica of the big table.I have gotten the create table, indexes and constraints script in the export file from my production DB. But in the forums I read, I noticed that I haven't gotten the create grant script, is there a view I could use to get this? Can dbms.metadata get this?
When I need to create an exact replica of my big table, I only need:
create table, indexes, constraints, and grants script right? Did I miss anything?
I just want to make sure that I haven't left anything out. Kindly help.
Thanks and Best Regards

Can dbms.metadata get this?
Yes, dbms_metadata can get the grants.
YAS@10GR2 > select dbms_metadata.GET_DEPENDENT_DDL('OBJECT_GRANT','TEST') from dual;
DBMS_METADATA.GET_DEPENDENT_DDL('OBJECT_GRANT','TEST')
GRANT SELECT ON "YAS"."TEST" TO "SYS"
When I need to create an exact replica of my big table, I only need:
create table, indexes, constraints, and grants script right? Did I miss anything?
There are triggers, foreign keys referencing this table (which will not permit you to drop the table if you do not take care of them), snapshot logs on the table, snapshots based on the table, etc...

WUT-113 Too many rows when using Webutil to upload a doc or pdf

Hi All,
I am using Webutil to upload and view files and am receiving the error msg 'WUT-113 Too many rows matched the supplied where clause'
The process works fine for uploading photos but not when I try and upload documents and pdf files.
I am on v 10.1.2.0.2 and using XP.
The code example (for documents) is outlined below but think that the issue must be to do with some sort of incorrect Webutil configuration
on my machine.
declare
     vfilename varchar2(3000);
     vboolean boolean;
begin
     vfilename := client_get_file_name('c:\',file_filter => 'Document files (*.doc)|*.doc|');
     vboolean := webutil_file_transfer.Client_To_DB_With_Progress
( vfilename,
'lobs_table',
'word_blob',
'blob_id = '||:blob_id,
'Progress',
'Uploading File '||vfilename,
true,
'CHECK_LOB_PROGRESS');
end;
Any assistance in this matter would be appreciated.
kind regards,
Tom

Hi Sarah,
Many thanks for the reply.
All I'm trying to do is to click on the Browse Document button in a form to upload
a document (in this example) from my machine and save it to the db table called lobs_table
using the webutil_file_transfer.Client_To_DB_With_Progress program.
When I first access the form the field :blob_id is populated (by a When-create-Record trigger)
with a value made up of sysdate in NUMBER format as DDMMHHMISS e.g. 0106101025
When I press 'Browse Document' - a button in the form) and the dialog box is opened and
I select a document and click ok then I see the error message 'WUT-113 Too many rows matched the supplied where clause' and yet the where clause element of the call to webutil_file_transfer.Client_To_DB_With_Progress program
should be the :blob_id value ('blob_id = '||:blob_id) i.e. should be a single value populated in the field when I first access the form - so why am I seeing the when too many rows error?
I may be missing something obvious as I've only just started using Webutil.
Kind regards,
Tom

List of Value: Best practice when there are too many rows.

Hi,
I am working in JDev12c. Imagine the following scenario. We have an employee table and the organization_id as one of its attributes. I want to set up a LOV for this attribute. For what I understand, if the Organization table contains too many rows, this will create an extreme overhead (like 3000 rows), also, would be impossible to scroll down in a simple LOV. So, I have decided the obvious option; to use the LOV as a Combo Box with List of Values. Great so far.
That LOV will be use for each user, but it doesn't really depend of the user and the list of organization will rarely change. I have a sharedApplicationModule that I am using to retrieve lookup values from DB. Do you think would be OK to put my ORGANIZATION VO in there and create the View Accessor for my LOV in the Employees View?
What considerations should I take in term of TUNING the Organization VO?
Regards

Hi Raghava,
as I said, "Preparation Failed" may be (if I recall correctly) as early as the HTTP request to even get the document for indexing. If this is not possible for TREX, then of course the indexing fails.
What I suggested was a manual reproduction. So log on to the TREX host (preferrably with the user that TREX uses to access the documents) and then simply try to open one of the docs with the "failed" status by pasting its address in the browser. If this does not work, you have a pretty good idea what's happening.
Unfortunately, if that were the case, this would the be some issue in network communications or ticketing and authorizatuions, which I can not tell you from here how to solve.
In any case, I would advise to open a support message to SAP - probably rather under the portal component than under TREX, as I do not assume that this stage of a queue error has anything to do with the actual engine.
Best,
Karsten

TOO MANY ROWS error experienced during DBMS_DATA_MINING.APPLY

On a test database that is running 10.1.0.2 when I execute APPLY specifying a data_table_name from another schema [data_schema_name], I get an ORA-1422, too many rows fetched.
However, when I exercise this same option [data table in another schema] on version 10.1.0.3, I get no error and the APPLY works.
Could someone tell me if this is an error that was fixed between the two versions and point me to the documentation that supports this?
Thanks,
Dianna

Dianna,
The behavior you observed could be as a result of some of the security bug fixes that our group have back ported to 10.1.0.3 patchset release. ST releases security bundle patches periodically and some of them were back ported to earlier releases.
There are no specific documentation regarding security bundle patch contents for security reasons.

Delete operation is not working to delete selected row from ADF table

Hi All,
We are working on jdev 11.1.1.5.3. We have one ADF table as shown below. My requirement is to delete a selected row from table, but it is deleting the first row only.
<af:table value="#{bindings.EventCalendarVO.collectionModel}" var="row"
rows="#{bindings.EventCalendarVO.rangeSize}"
emptyText="#{bindings.EventCalendarVO.viewable ? applcoreBundle.TABLE_EMPTY_TEXT_NO_ROWS_YET : applcoreBundle.TABLE_EMPTY_TEXT_ACCESS_DENIED}"
fetchSize="#{bindings.EventCalendarVO.rangeSize}"
rowBandingInterval="0"
selectedRowKeys="#{bindings.EventCalendarVO.collectionModel.selectedRow}"
selectionListener="#{bindings.EventCalendarVO.collectionModel.makeCurrent}"
rowSelection="single" id="t2" partialTriggers="::ctb1 ::ctb3"
>
To perform delete operation i have one delete button.
<af:commandToolbarButton
text="Delete"
disabled="#{!bindings.Delete.enabled}"
id="ctb3" accessKey="d"
actionListener="#{AddNewEventBean. *deleteCurrentRow* }"/>
As normal delete operation is not working i am using programatic approach from bean method. This approach works with jdev 11.1.1.5.0 but fails on ver 11.1.1.5.3
public void deleteCurrentRow (ActionEvent actionEvent) *{* DCBindingContainer bindings =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding dcItteratorBindings =
bindings.findIteratorBinding("EventCalendarVOIterator");
// Get an object representing the table and what may be selected within it
ViewObject eventCalVO = dcItteratorBindings.getViewObject();
// Remove selected row
eventCalVO.removeCurrentRow();
it is removing first row from table still. Main problem is not giving the selected row as current row. Any one point out where is the mistake?
We have tried the below code as well in deleteCurrentRow() method
RowKeySet rowKeySet = (RowKeySet)this.getT1().getSelectedRowKeys();
CollectionModel cm = (CollectionModel)this.getT1().ggetValue();
for (Object facesTreeRowKey : rowKeySet) {
cm.setRowKey(facesTreeRowKey);
JUCtrlHierNodeBinding rowData = (JUCtrlHierNodeBinding)cm.getRowData();
rowData.getRow().remove();
The same behavior still.
Thanks in advance.

JDev 11.1.1.5.3 sounds like you are using oracle apps as this not a normal jdev version.
as it works in 11.1.1.5.0 you probably hit a bug which you should file with support.oracle.com...
Somehow you get the first row instead of the current row (i guess). You should debug your code and make sure you get the current selected row in your bean code and not the first row.
This might be a problem with the bean scope too. Do you have the button (or table) inside a region? Wich scope does the bean have?
Anyway you can try to remove the iterator row you get
public void deleteCurrentRow (ActionEvent actionEvent) { DCBindingContainer bindings =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding dcItteratorBindings =
bindings.findIteratorBinding("EventCalendarVOIterator");
dcItteratorBindings.removeCurrentRow();Timo

Exception too many rows...

Hi
I am getting two different outputs with following code depending upon i declare the variable in first or second way...
when i declare the variable v_empno as number(10) and too many rows exception is raised....and after that i dbms this variable..it is null...
but when i declare the same variable as table.column%type....and the similar scenario happens and i dbms the value of variable...it is not null...rather the first value from output of the query...
declare
--v_empno number(10);
v_empno emp.empno%type;
begin
dbms_output.put_line('before '||v_empno );
select empno into v_empno from emp;
dbms_output.put_line('first '||v_empno);
exception when too_many_rows then
dbms_output.put_line('second '||v_empno);
dbms_output.put_line('exception'||sqlerrm);
end;
is there any specific reason for this....
ur comments plz
Thanks
Sidhu

and keeps it when the excaprion is raised.
