Deleting a row from a Row Repeater

Hi All,
How could i delete a row from a row repeater??????
I am using REMOVE_ELEMENT method from IF_WD_CONTEXT_NODE interface... Is this the correct way!!!!!!.
Is there anyother way to do the same?????
Best Regards.
Shafiq Ahmed Khan.

Hi
first u get the index from the context element. with the help of the index u can get that particular element using get element.
then u remove the element .
check this code.
CALL METHOD context_element->get_index
receiving
    my_index = lv_index.
CALL METHOD lo_nd_rcf_edu_det->get_element
EXPORTING
    index        = lv_index
receiving
    node_element = lo_el_rcf_edu_det .
CALL METHOD lo_nd_rcf_edu_det->remove_element
EXPORTING
    element          = lo_el_rcf_edu_det
receiving
   has_been_removed =
Declare a parameter context_element in the method of type if_wd_context_element

Delete overlapping requests from cube not working in processchain.

In a process chain, 'deletion of overlapping requests from the cube ' step is used.
Before this step a DTP step runs with a full update to load the cube. This process chain is scheduled every day.
Issue is, the process chain failed at the DTP step and after correcting and repeating, the step got executed.
However, the next step after the DTP,'delete overlapping requests from the cube'
gets executed but without deleting the previous day's request.
In the step details a message that 'No request for deletion were found' can be seen.
Then next day when the DTPstep is executed without any problem the 'delete overlapping requests from cube' step is successful
and the previous requests from cube are deleted.
the deletion selections in the step ' delete overlapping request from infocube' is
Delete existing requests
Conditions:
only delete requests from same DTP
Selections
Same or more comprehensive
Because of this issue on a particular day because of the presence of 2 days requests the data is getting aggregated and shown as double in the reports.
Please help.

Hi Archana,
When you delete the bad request from target and before repeating your DTP in PC, make sure the bad request deleted from table RSBKREQUEST also.
If you find the same request in table, first delete the request from table and repeat the DTP in PC.
Now Delete overlapping step should work.
As this is not the permanent solution, please raise an OSS for SAP

Error while deleting a row from the Entity Object

Hi OAF Guys,
i am unable to delete the newly created row from the entity object.
let me explain my scenario.
1. i have a table of which some of the columns are mandatory.
2. I am writing the code in the validateEntity to check wether the user really enter anything into the fields.
3. My problem is, when the user creates row and wanted to delete the row without entering any details, the validate entity of the EO gets fired which will not allows to delete the row.
Is there any workaround for this problem.
Regards,
Nagesh Manda.

Hi Tapash,
I am very sorry for not providing you the complete details of my scenario. Here i am explaining
1. what code you have placed while creating the row and in validation method on EOImpl.
while creating a new row i am initializing the primary key of the EO with the sequence value.
2.When you say, you are unable to delete the row, are you getting a error message ? if yes, custom message or fwk error ?
its not the fwk error, its the custom message which wrote in my validateEntity method of EO to check whether the user had entered all the necesary columns or not.
3.How are you trying to delete the row ?
while the user clicks on the delete switcher i am getting the primary key of the row and searching for the row in the vo and finally deleting it.
The problem arises when the user creates a row, and later doesnt want to enter the details and delete it. Here while deleting the row the validateEntity method of the EO gets fired and doesnt allow me to do so :(.
Any way appreciate your help tapash.
Regards,
Nagesh Manda.

Deleting 1 row from a table takes too long...why?

We are running the following query...
delete gemdev.lu_messagecode where mess_code ='SSY'
and it takes way too long as there is only 1 record in this table with SSY as the mess_code.

Now, since the table only has 150 rows, and I am only try to delete 1 row, why is there so much disk read and why does it take 5 minutes to delete? This just weird. Does this have something to do with the Child tables?

Any triggers on the table?
If you trace the session, what statement(s) seem to
be taking all that time?
JustinWell I traced my session and I noticed that my query does take a while, but I also noticed several other queries that I was not running. Not too sure where it came from. Have a look below. It is a sample from my TKPROF utility report.

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.
Please refer to:
DELETE (SQL Server Compact)
FROM Clause (SQL Server Compact)

You mean when you click on the hyperlink you want that row to disappear from the page, but not delete the row from the database until a commit/submit button is pressed?
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 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

Deleting the Row from the table is not refreshing the contents in the form

Hi,
We developed a table and form in the same UI based on the following suggestion.
Display and edit currently selected row of ADF Table in ADF Form
1. Created one view object based on the employees table.
2. dragged the view object to the UI as table.
3. dragged the view object as form.
4. set partial triggers on the form's container (panelformlayout) as tableId.
Tested the application with the edit options and everything is working fine. But the problem comes when we delete the record from table. it is not refreshing the form based on the newly selected row after deleting the record. If we commit the data the form contents are updated to the selected row (which is not desired).
Can you please suggest how to fix the issue, refreshing the form with the selected row after deleting the records.
Thanks and Regards,
S R Prasad

The Code snippet looks fine. I think, the issue is in the partial trigger setting
4. set partial triggers on the form's container (panelformlayout) as tableId.In order to the table to get refreshed, the table's partialTriggers property should be set to id of the delete Button.
Go to table, select partialTriggers in the Property Inspector, Click on Expression Builder at the right and select the delete Button.
Can you set this and check?
Sample Code:
<af:panelHeader text="panelHeader 1" id="ph1">
<f:facet name="context"/>
<f:facet name="menuBar"/>
<f:facet name="toolbar">
<af:commandButton text="Delete" id="cb1"/>
</f:facet>
<f:facet name="legend"/>
<f:facet name="info">
<af:table var="row" rowBandingInterval="0" id="t1"
partialTriggers="::cb1">

Ok... but I am a little confused (sorry to be a nuisance ),
my delete function within my webService requires an ID to be
passed from the Flex application, thus when a row is selected, the
ID of the selected row is taken, so when the Delete button is
pressed it sends this ID to the webService where it is taken and
used - and therefore deleting the row etc.....
Do you mean to define the result handler for the deleteOPG
operation in the main webService tag, i.e. :
<mx:WebService id="wsData" wsdl=http://...?wsdl>
<mx:operation name="getRes" result="handleWSR(event)"/>
<mx:operation name="deleteOPG"
result="handleWSR_deleteOPG(event)"/>
</mx:WebService>
and then call it in my delete function, passing the ID from
my delete function to my new result handler function ??? :
Thanks,
Jon.

Deleting a row from a Procedure

Hi All
Can one of you tell me how to delete a row from a Procedure
It is created with
CREATE OR REPLACE PROCEDURE report.NAMEOFTABLE
(nPutId IN Report.ID%TYPE,
cArea IN Report.Area%TYPE,
cSubject IN Report.Subject%TYPE,
nUserId IN Report.EngineerID%TYPE,
cDesc IN Report.Description%TYPE,
cSide IN Report.SideEffects%TYPE,
cImpact IN Report.Impact%TYPE,
cNotes IN Report.Notes%TYPE,
nValid IN Report.Valid%TYPE) AS
-- Add or update Report
-- If nId < 1 then a record is added, otherwise updated.
BEGIN
IF nId < 1 THEN
INSERT INTO Report
(Area, Subject, EngineerID,
Description, SideEffects, Impact,
ReportNotes, Valid)
VALUES
(cArea, cSubject, nUserId, cDesc, cSide, cImpact, cNotes, nValid);
ELSE
UPDATE Report
SET ReportArea = cArea,
ReportSubject = cSubject,
ReportDescription = cDesc,
ReportSideEffects = cSide,
ReportImpact = cImpact,
ReportNotes = cNotes,
ReportValid = nValid
WHERE ReportID = nPutId;
END IF;
COMMIT;
END;
CREATE SYNONYM Admin.NAMEOFTABLE
Report.NAMEOFTABLE;
But I need to make 1 field of the impact and the sideEffect called the ImpactEffect
So how do i delete the field of Side effect and change the name of the Impact field.
Sould I make a new Procedure?

If you want to delete a row, you'd need a DELETE statement. It is not obvious to me, though, that you really want to delete a row. It sounds like you're trying to update a row, and there is an UPDATE statement in the procedure. Unfortunately, I'm very unsure exactly what you're trying to accomplish and how this procedure relates to that goal. Perhaps if you could post the starting state of the row, the procedure call you're trying to make, and the end state of that row, things might be much clearer.
As an aside, do you really have a schema and a table named REPORT? That seems rather confusing.

Deleting a row from a table control through right-click menu

I have a table control. I want to delete a row from it when a user right clicks on a particular row and selects "Delete row" menu item. I have managed the creation of menu item but have not been able to delete the row which is right clicked and the menu item "Delete row" is selected. Guidance required! Thanks!

It's irrelevant whether the table is a control or indicator. See attached VI.
Hi smercurio,
please see the attached picture. In my previous post i mean the different in the menu. The red marked function is not available, if the table is an indicator. LV8.5!

Deleting a row from matrix by context menu

Hi all
does anyone know how can i cause right click on mouse button. on a certain row within a matrix to show a context menu with the option to delete the row. and when pressing the menu item handling the event of deleting the row from the matrix?
appreciate the help
Yoav

Hi Yoav,
Simply, 'context menu' have to be handled with 'menu event' object.
It can be done by 'flushToDataSource' method and some tricks.
Basically, method delete the row without any clause of addon code.
But it's only can be done in display side.
If you're using DBDataSource, you have to flush to the datasource.
I mean, you have to update datasource with the data displayed in the matrix.
and then, delete the last row of the datasource.
FlushToDataSource doesn't affect to the number of rows in the datasource.
You have to delete a row with a method of DBDatasource.. I can't remember the name.
If, the matrix uses userdatasource, you don't need to delete a row in datasource.
Because userdatasource doesn't have a concept of 'row', actually.
Hope this helpful for you.
Regards,
Hyunil Choi

Deleting a row from JTable

I am trying to delete a row from a JTable whenever the button on the last column is pressed. I know to do this, I can use the removeRow(int) method of the tableModel. But the odd thing is when I try to get a handle to the TableModel from the JTable to use that function, i.e. table.getModel().removeRow(int) it doesn't work. But if I explicitly pass in the tableModel into my class it does work. Here's the code below:

                   text = ((value == null) ? "": value.toString());
                   editButton.setText(text);
                   selectedRow = row;
                   return editButton;
              return defaultEditor.getTableCellEditorComponent(
                        table, value, isSelected, row, column);
        public Object getCellEditorValue()
            return text;
        public void actionPerformed(ActionEvent e)
            fireEditingStopped();
            // This works
            tableModel.removeRow(selectedRow);
           // This does not work
          // table.getModel().removeRow(selectedRow);
}Take a look at the actionPerfformed method. One way of doing it works, one doesn't. Just trying to understand why me getting a handle to the tableModel through the table doesn't work.

It gives me a run-time error Well then your question should be "why do I get this run-time error" and then you would quote the error. Be more descriptive. "It doesn't work" is not descriptive.
table.getModel().removeRow(selectedRow);I don't use JDK1.5 either. But if you are saying that the above line compiles cleanly with JDK1.5 (because of the auto-boxing feature, or whatever its called), then I see no reason why the code wouldn't work since it recognizes the class as a DefaultTableModel.
Presumably you commented out the other line so you don't try to delete the row twice. Otherwise you might be getting a indexing error.

Deleting a row from a database...

Here is the method I am calling to delete a row from a database. I keep getting this error, but I am not sure why.
Error: "Too few parameters. Expected 1."
//To delete a row
public void removeRow(String x, String y) {
   try {
   Statement stmt = con.createStatement();
   //delete row with same x and y
//first is a string and second is a number
   String query = "DELETE * FROM table WHERE first = '" +x+ "' AND " +
   "second = " +Integer.parseInt(y);
   int result = stmt.executeUpdate(query); //runs delete query, ERROR HERE *************
   System.out.println("Test"); //debug statement, never gets here
   //deletion confirmation message
   JOptionPane.showMessageDialog(null, "Row deleted",
   "Delete Reservation", JOptionPane.INFORMATION_MESSAGE);
      catch (Exception e) { System.out.println(e); }

Additionally, in the future you might want to use:
catch(SQLException sqlx) {
System.out.println( sqlx.getSQLState()
                                   +"\t"+sqlx.getMessage()
                                   +"\t"+sqlx.getErrorCode() );... It'll help with diagnostics.
