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

Deleting Multiple Rows From Multiple Tables As an APEX Process

Hi There,
I'm interesting in hearing best practice approaches for deleting multiple rows from multiple tables from a single button click in an APEX application. I'm using 3.0.1.008
On my APEX page I have a Select list displaying all the Payments made and a user can view individual payments by selecting a Payment from the Select List (individual items are displayed below using Text Field (Disabled, saves state) items with a source of Database Column).
A Payment is to be deleted by selecting a custom image (Delete Payments Button) displayed in a Vertical Images List on the same page. The Target is set as the same page and I gave the Request a name of DELETEPAY.
What I tried to implement was creating a Conditional Process On Submit - After Computations and Validations that has a source of a PL/SQL anonymous block as follows:
BEGIN
UPDATE tblDebitNotes d
SET d.Paid = 0
WHERE 1=1
AND d.DebitNoteID = :P7_DEBITNOTEID;
INSERT INTO tblDeletedPayments
( PaymentID,
DebitNoteID,
Amount,
Date_A,
SupplierRef,
Description
VALUES
( :P7_PAYMENTID,
:P7_DEBITNOTEID,
:P7_PAID,
SYSDATE,
:P7_SUPPLIERREF,
:P7_DESCRIPTION
DELETE FROM tblPayments
WHERE 1=1
AND PaymentID = :P7_PAYMENTID;
END;
The Condition Type used was Request = Expression 1 where Expression 1 had a value of DELETEPAY
However this process is not doing anything!! Any insights greatly appreciated.
Many thanks,
Gary.

...the "button" is using a page level Target,...
I'm not sure what that means. If the target is specified in the definition of a list item, then clicking on the image will simply redirect to that URL. You must cause the page to be submitted instead, perhaps by making the URL a reference to the javaScript doSubmit function that is part of the standard library shipped with Application Express. Take a look at a Standard Tab on a sample application and see how it submits the page using doSubmit() and emulate that.

Delete multiple rows in a JTable ADF Swing.

hi guys,
Would anyone know tell me how do I delete multiple rows in a JTable ADF Swing?
JDeveloper.

Hi,
I would configure the table for multi row selection. Then get the selected row index, access the iterator in the PageDef file (through the panelBinding reference you have in ADF Swing) and then iterate over the selected row indexes, make an index to become the current row and call remove() on it

Deleting multiple rows from SUD dialog table

Hi,
I have some SUD dialog tables that I would like to delete some rows from. I can select and delete all or one row (using a SUD button that finds out which one row was selected or if all, and then deleting them with the table.rows.remove command), but I seem to have troubles if I want to select multiple rows (either in a range, ex: rows 3-10, or non-sequential, ex: 1, 4, 6 and 23). I just started working on this but thought maybe someone has already done this and can save me the trouble!
Thanks!
Julia Moeller

Hi Julia,
Just a quick guess-- try looping backwards and deleting the last rows first:
FOR i = 10 TO 3 Step -1
table.rows.remove i
NEXT
Haven't tested it, so no guarantees,

DELETE MULTIPLE ROWS FROM MATRIX

Hi all,
I´M DESPERATED.
I am able to delete row by row in my matrix, but ¿Could anyone post a sample to delete multiple rows?
I´ve been trying several ways but it doesn´t work.
My code is:
========================
Dim i As Long = oMatrix.GetNextSelectedRow
                If i > -1 Then
                    If oMatrix.IsRowSelected(i) = True Then
                        oMatrix.DeleteRow(i)
                    End If
========================
Thank you in advanced,
lorenzo

Don´t worry, It was a problem with my loop.
Thanks anyway

Deleting a row from a JTable using a custom TableModel

Before I waste any of your time I would like to go ahead and just say that I have searched through the forum using "delete row from Jtable" as the search keywords and while I have found very closely related issues, they have not solved my problem. I have found code postings by carmickr and his arguments as to why we should use DefaultTableModel instead of having created our own custom TableModel, and while I do agree, I just am not quite confident enough in applying it to my scenario. See I am reading from a file a bunch of Contractor objects and I am stuffing it into an arraylist which I am using in the following code posting to populate my TableModel which the JTable object in the gui then uses.
My problem is that everything works except when I delete and when I delete I understand that the index is changing because I just removed a row from the arraylist object. Suppose I have 33 rows displaying in the GUI. Now after I delete say row #23, the delete function works and dutifuly the row disappears from the table, but if I try to delete a row say...the last row, it does not work and throws me an IndexOutOfBoundsException which totally makes sense. My question is how do I go about fixing it? Do I have to do something with the setRowCount method?
Any help is appreciated.
Cheers,
Surya

Wow that was a very quick response. Thanks camickr. I am only trying to delete a single row. I do not know how to go about posting a test program for the code I have posted above because honestly the gui itself is 800 lines of code, and then the file reading class is quite funky in itself. I can maybe email you the entire Netbeans project including code so if you are using Netbeans 5 RC2 you can run the code and see for yourself, but that would not be considerate of me.
See I am trying to delete any row at any time...but only one at a time not multiple rows...so if a user decides to delete row 23 and then tries to delete the last row which happens to be row 33 in my case, my setup should be smart enough to still allow to delete the row.

Deleting a row from my Jtable

I have MyTableModel class:
class MyTableModel extends AbstractTableModel{
         private Object columnNames[];
         private Object[][] data;
         public MyTableModel(Vector colonne, Vector corpoTabella){
              columnNames= new Object[colonne.size()];
              int nRighe=corpoTabella.size()/colonne.size();
              data=new Object[nRighe][colonne.size()];
              //inizializzo l'intestazione della tabella:
              columnNames= colonne.toArray();
              //inizializzo il corpo della tabella
              for(int i=0, k=0;i<nRighe;i++){
                   for(int j=0;j<colonne.size();j++){
                        data[i][j]=corpoTabella.get(k);
                        k++;
        public int getColumnCount() {
            return columnNames.length;

            return data[row][col];
        public boolean isCellEditable(int row, int col) {
                return false;
    }And I use it to create a JTable:
table=new JTable(new MyTableModel(colonne,corpo));I read on the tutorial to delete a row I have to use the DefaultTableModel in order to activate the removeRow method, but now how could I implementate it to delete rows?

ok now I have:
modelloTab=new MyTableModel(colonne,corpo);
table=new JTable(modelloTab);
class MyTableModel extends DefaultTableModel{
so I can write without errors:modelloTab.removeRow(0)but despite I wrote a lot of rows in the table when I run it I have a java.lang.ArrayIndexOutOfBoundsException ...what can I do?

Delete multiple rows from table/list control

Hi,
I want to have a table control in which a user can enter different entries, like this:
My program would read each entry at a time and do something.
However, I would like to give the user ability to delete multiple entries at once, like in an Excel spreadsheet - that is, the user selects multiple rows and presses "Delete" key and those entries get deleted. The Labview table does not allow this it seems - I can only delete one entry at a time - or I have to right-click and select Data Operations->Cut Data, which is awkward.
Is there a control better suited to what I want to do? I tried a Llist control, but it behaves in the same manner.
Thanks in advance!
Solved!
Go to Solution.

You could write your own routine. Use an Event Structure with a Key Down event. If the delete key was pressed and the table has focus delete the elements that are selected.

Delete multiple rows from text file

HI,
i have a text file and i want to remove first few rows from that text file not last rows.
how can i do that ?
thanks

because i suspect this is a homework assignment i'm not going to give you the fish, but i will teach you how to fish! =P
go investigate the Java Standard class called: BufferedReader. Look specifically at the method readLine()
combine that with a for loop, and an IF-THEN statement to weed out the lines you don't want (or just govern that with the FOR loop's index), and you should be able to figure it out....
good luck! give it a whirl...

How do i delete multiple rows in JTable

hello
how i delete multiple rows in JTable
when i selected multiple rows from the jtable and delete its give the error ArrayIndexOutOfBoundException
e.g.
int rows[]=jtable.getSelectedRows();
for(int i=0;i<rows.length;i++)
DefaultTableModel model=(DefaultTableModel)jtable.getModel();
model.removeRow(rows);
like this
please help me
meraj

You are trying to remove the rows an equal times to the amount of rows selected.
You should remove one row at a time:
model.removeRow(rows);
Change your code into this.
for(int i=0;i<rows.length;i++)
DefaultTableModel model=(DefaultTableModel)jtable.getModel();
model.removeRow(rows[i]);

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.

                   boolean isSelected, int row, int column){
              if (column == buttonColumn){
                   text = ((value == null) ? "": value.toString());
                   editButton.setText(text);
                   selectedRow = row;

        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.
