-----1st one thing let me know vo is eo based .???.
If not here is the sample code to delete a row not from the data base.:
public void Deleterow(OAPageContext pageContext, OAWebBean webBean,String prjid)
int idtodelete;
int fetchedrowcount;
Number prjojectid;
RowSetIterator deleteIter;
prjidtodelete=Integer.parseInt(prjid);
OADBTransaction tr = getOADBTransaction();
ProjectsVORowImpl row=null;
ProjectsVOImpl vo= getProjectsVO1();
fetchedrowcount=vo.getRowCount();
deleteIter = vo.createRowSetIterator("deleteIter");
deleteIter.setRangeStart(0);
deleteIter.setRangeSize(fetchedrowcount);
for(int i=0;i<fetchedrowcount;i++)
row= (ProjectsVORowImpl)deleteIter.getRowAtRangeIndex(i);
prjojectid=(Number)row.getAttribute("ProjectId");
if (prjojectid.compareTo(prjidtodelete)==0)
row.remove();
break;
deleteIter.closeRowSetIterator();

ShashidharHi Frank,
Thanks for reply!!
My case is:
I have a Query based ViewObject.
One of the field is LOV and remaining fields are in ADF table. the LOV field is out side ADF table when i insert first record in ADF table and i choose LOV filed the value is selected.
when i create second row LOV value got refreshed because both are in same VO.
I need to get the LOV value of first row and set same value to second Row.

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
Example 134 here: http://blogs.oracle.com/smuenchadf/examples/#134 provides you with the code

How To Delete a Row From a TableView !!!!
Hi,
Does any know how to delete a row from a table view model.
I have a TableViewModel being displayed, when the user select the particular row and click delete i want that particular row to be deleted.
Any Suggestions How.
Thanks,
Emmanuel.If u want to delete single row, then set the property of TableView - selectionMode="SINGLESELECT". Select the radio button and click on delete button. In the main program, you can get the row value like...
public void onDeleteButtonClicked(Event event) throws PageException {
TableView table = (TableView) this.getComponentByName ("idTableView");
DefaultTableViewModel dmodel = myBean.beanModel;
String pid = "", row_selected;
// Get the first visible row
int firstVisibleRow = table.getVisibleFirstRow();
// Get the last visible row
int lastVisibleRow = table.getVisibleLastRow();
for (int i = firstVisibleRow; i <= lastVisibleRow; i++) {
if (table.isRowSelected(i)) {
row_selected = i;
pid = dmodel.getValueAt(i, 1).toString();
"i" will give you the row no, pid has the value of the row at first column.
Hope this helps.
Thanks,

Personally, I think I'd prefer that you have a delete checkbox next to every row and NOT remove them from the display if I was a user. You give your users a chance to change their mind about their choice, and when they're done they can see exactly which rows will be deleted before they commit.
You know your problem, of course, so you might have a good reason for designing it this way. But I'd prefer not removing them from the display. JMO - MOD -
How to delete certain rows from Table view
Hi Experts,
I need to display result on the basis of certain process type. So i have used code like below.
lv_iterator = me->typed_context->searchresult->collection_wrapper->get_iterator( ).
lv_entity = lv_iterator->get_first( ).
WHILE lv_entity IS BOUND.
CLEAR:lv_object.
lv_object = lv_entity->get_property_as_string( iv_attr_name = 'PROCESS_TYPE' ).
IF lv_object <> 'XXX'.
lr_entity ?= lv_entity.
me->typed_context->searchresult->collection_wrapper->remove( lv_entity ).
lr_entity->delete( ).
ENDIF.
lv_entity = lv_iterator->get_next( ).
ENDWHILE.
But only some of the entities from the collection are getting removed. Still some wrong entities exists which i cant even able to delete it by using ,
me->typed_context->searchresult->collection_wrapper->remove( lv_entity ).
lr_entity->delete( ).
Am i missing anything here?

SanthoshHi Santhosh,
Maybe that is happening because you're removing elements from an object (collection_wrapper) inside your loop.
Can you try to create an collection wrapper copy by using GET_COPY method, and then use and loop the iterator on your copied object, and remove the unwanted entities on your main object?
Kind regards,

How to delete a row from AbstractTableModel
my table is using an object to populate the data.
static Object[][] data = new Object[LineCount()][5];
So when I delete a row, I should delete from the model or the object?
RgdsWhen you populate your table with a two dimensional array, the table actually creates a DefaultTableModel (which extends AbstractTableModel). The DefaultTableModel has methods which allow you to add/remove row from the data model. Read the DefaultTableModel API for more information.

How to delete single row from multiple

2 |M992 | 74 |M6
2 |M995 | 74 |M6
2 |M998 | 74 |M6
Here output shows that CUSTMAST_REQUEST_SRNO M984 having two same rows. And now i want
to delete any one of row from that. So, how can i apply it for multiple rows ?
Can any body help-out me in that?
Thank You,

How to delete zero rows from a matrix?
Hi,
I have a 2D datamatrix and there are some zero rows. My original program should recognize all zero rows and delete them. How to do that?
I have tried with the Delete From Array function but no success. I also tried with the OpenG array functions but...no.
I attached a vi which simulates my problem. There is one zero row and I want to delete it and have a matrix without zero rows.
Kudos for any good help!
Solved!

The idea was to give a hint that people try using their brain....
Stilll, I think your code is fundamentally flawed and will thus lead the student into a deep swamp.
Have you actually tried it with multiple rows of zeroes?
Since "delete from array" rearranges the array indices with each deletion, the code will break if there is more than one row to be deleted. For example if a row is already deleted and it needs to also delete the last row, it would try to delete a row that no longer exists. If a later row still exists, it will delete the wrong row.
Also, since NaN gets coerced to a valid index (2147483647), it's probably not such a good idea. "-1" would be a better choice. (Well, it's an unlikely implossible possibility in LabVIEW 32 bit, but still....)
I also don't understand your logic with "search array". You need to test all elements for zero.

How to delete a row from a SQL Server CE Table with multiple JOINs?
I want to delete a record from a SQL Server CE table.
There are 3 tables scripts, options and results. I would like to remove a record from the results table. The where clause contains dynamic information which retrieved via other queries to different tables in the same database. These queries work fine and deliver
the desired data.
The Compact server is a clone of a remote table created using the sync framework. The same query to the remote table works fine.
The error I get is:
There was an error parsing the query. [ Token line number = 1,Token line offset = 10,Token in error = from ]
The code that throws the exception is as follows:
Dim connLoc As SqlCeConnection = New SqlCeConnection(My.Settings.ConnectionString)connLoc.Open() Dim strDel As String = "Delete r from ResultsTable r inner join OptionsTable o ON o.TestName=r.TestName inner join ScriptTable c ON r.TestName=c.TestName WHERE r.TestName = '" & ds1Loc.Tables(0).Rows(0)(1) & "' AND [Index] = '" & lstIndex & "'"Dim cmdDel As SqlCeCommand = New SqlCeCommandcmdDel.CommandText = strDelcmdDel.Connection = connLoccmdDel.ExecuteNonQuery()
The values held in ds1Loc.Tables(0).Rows(0)(1) and lstIndex are
correct so should not be the problem.
I also tried using parameterised queries
Dim strDel As String = "Delete r from [ResultsTable] r inner join [OptionsTable] o ON o.TestName=r.TestName inner join [ScriptTable] c ON r.TestName=c.TestName WHERE r.TestName = @TestName AND [Index] = @lstIndex"
Dim cmdDel As SqlCeCommand = New SqlCeCommand cmdDel.CommandText = strDel
With cmdDel.Parameters
.Add(New SqlCeParameter("@TestName", ds1Loc.Tables(0).Rows(0)(1)))
.Add(New SqlCeParameter("@lstIndex", lstIndex))
End With
cmdDel.Connection = connLoc cmdDel.ExecuteNonQuery()
I have tried replacing the "=" with "IN" in the the WHERE clause but this has not worked.
Is it the join that is causing the problem? I can do a select with the same search criteria and joins from the same database.
Also this query works with SQL Server. Is it perhaps that SQL CE does not support the Delete function the same as SQL Server 2008? I have been looking at this for a while now and cannot find the source of the error. Any help would be greatly appreciated.Hello,
In SQL Server Compact, we can use join in FROM clause. The DELETE statement fail may be caused by the FOREIGN KEY constraint.

DELETE (SQL Server Compact)
FROM Clause (SQL Server Compact)
