Delete multiple rows with BC4J

I can't find anything on multi-delete with ADF.
Is it supported?
ViewObjectImpl v = (ViewObjectImpl)am.findViewObject("X");
ViewCriteria vc = v.getViewCriteria("Y");
v.applyViewCriteria(vc);
v.executeQuery();
v.removeAllSelectedRows(); //Delete all rows selected by vc "Y"
getDBTransaction().commit();
Thanks

Thanks Timo, I had figured that one out, that's how we did it in the first place but its not acceptable for my Use Case.
The goal for me is to have something that can scale, I don't want to loop through my millions of records and remove them one by one, hence take a hit on performance.
I assume there is somehow a way to do mass update/deletes with ADF/BC4J?
Cheers

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

Updating and deleting multiple rows

Hi!
I have a form on a table with report page where I can filter data through columns.
1. Is it possible to create a button that will delete all the filtered data?
2. Also, I would like to be able to update any column of the filtered dataset to a certain value (that needs to be input somehow). Is that possible?
So far I can only update or delete one row at a time, which isn't useful as I sometimes need to change 100 rows at a time with the same value or delete them.
When I use tabular form, I can't filter rows, but I can delete multiple rows...
Also if there are similar examples, could you please send me a link; I can't seem to find any.
I'm using Apex 4.2.2.
Best Regards,
Ivan

Deleting multiple rows - [url https://forums.oracle.com/forums/thread.jspa?threadID=2159983]common question
Best answered with Martin's example

Depends how you filter your data. You could identify all your limiting variables, and reverse the where clause in a delete process.
As for point 2, you can define a button that redirects to the page, and you can defined all the item values you like using the Action link.
There is likely an example in the supplied package applications.

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.

Deleting multiple rows in a report ?

db11gxe , apex 4.0 , firefox 24 ,
how to delete multiple rows in a report at one time ?
thanks

Hi newbi_egy,
Here is a small demo with few steps that can be used in your scenario-
1) Below is the query of a report on emp table which has empno column with unique values-
SELECT APEX_ITEM.CHECKBOX(1,empno) " ", ename, job FROM emp ORDER by 1
2) A Delete button is created that submits the page.
3) An on-submit process is created with Process point On Submit - After Computation and Validations with condition that the below process runs when Delete button clicked.
BEGIN
FOR i in 1..APEX_APPLICATION.G_F01.count
LOOP
delete from emp where empno=APEX_APPLICATION.G_F01(i);
END LOOP;
END;
I hope this might help you.

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,

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

Web dynpro screen with multiple rows with columns that can be edited

Web dynpro screen with multiple rows with columns that can be edited individually:
Hi
I am busy creating a screen in web dynpro for ABAP which we would like to make available via Portal ESS (Portal 7).
I need to add 'n type of table (or almost something like Excel) or something in which someone can type a few paycode numbers (there should be lets say 10 blank rows in which info can be typed in and if I click on a button or so, more rows must be added if necessary. Then in the other colums stuff like amounts must be entered which one should also be able to edit then and there.
Can anyone assist in what I can use for this? There does not seem to be some existing element that I can use.
Help will be appreciated.
Regards
Debbie

Hi Debbie,
Whiel Creating table you need to be care full that use chose INPUT FIELD as the CELL EDITOR. Just guessing that if ur table is not editable u might have choosen TextView as default cell editor type.
check link for details on TABLE UI
[http://help.sap.com/saphelp_erp2005/helpdata/EN/b5/ac884118aa1709e10000000a155106/frameset.htm]
easy way is to first add UI ELEMENT TABLE to your VIEW, then right click over it & select create binding from context. After you have a pop up where you can select what columns you want what should be its cell editor etc.

Can we create JTable with multiple rows with varying number of columns ?

Hi All,
I came across a very typical problem related to JTable. My requirement is that cells should be added dynamically to the JTable. I create a JTable with initial size of 1,7 (row, columns) size. Once the 7 columns are filled with data, a new row should be created. But the requirement is, the new row i.e. second row should have only one cell in it initially. The number of cells should increase dynamically as the data is entered. The table is automatically taking the size of its previous row when new row is added. I tried by using setColumnCount() to change the number of columns to '1' for the second row but the same is getting applied to the first row also.
So can you please help me out in this regard ? Is it possible to create a JTable of uneven size i.e. multiple rows with varying number of columns in each row ?
Thanks in Advance.

Well a JTable is always going to paint the same number of columns for each row. Anything is possible if you want to rewrite the JTable UI to do this, but I wouldn't recommend it. (I certainly don't know how to do it).
A simpler solution might be to override the isCellEditable(...) method of JTable and prevent editing of column 2 until data in column 1 has been entered etc., etc. You may also want to provide a custom renderer that renderers the empty column differently, maybe with a grey color instead of a white color.

It works always :
DCBindingContainer binding=(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding iterator=binding.findIteratorBinding(iteratorName);
ViewObjectImpl vo=(ViewObjectImpl)iterator.getViewObject();
Vector vector=new Vector();
for(int i=0;i<vo.getRowCount();i++)
Row row=vo.getRowAtRangeIndex(i);
if(row.getAttribute("IsSelect")!=null)
if((Boolean)row.getAttribute("IsSelect")==true)
vector.add(row);
Row[] rows=new Row[vector.size()];
for(int i=0;i<vector.size();i++)
rows=(Row)vector.get(i);
if(rows.length>0)
for(int i=0;i<rows.length;i++)
rows[i].remove();

Select or deselect multiple rows with one single selection event

Does anyone know how to create a JTable which can select or deselect multiple rows with one single selection event in JTable. Fore example, if the table has
row1
row2
row3
row4
row5
row6
What I need is when user select row1 or row2, both row1 and row2 should be set to be selected. Then if user press CTRL and click one of row3 or row4, both of them should be selected including the previouse selected row1 and row2.
For deselection, if row1 and row2 are selected, when users deselect one of row1 or row2, both of them should be deselected.
Hopefully someone can give me a hint.

Here is a partial solution using a JList. Only one line gets highlighted when the user makes a selection in the list. But, two lines are returned. There is a blank line between every two lines.
     private void addLineToList() {
          String a = f_one.getText();
          String b = f_two.getText();
          if (a.length() == 0) {
               Utils.showInformationMessage("Item field is empty.");
               f_one.requestFocusInWindow();
               return;
          if (b.length() == 0) {
               Utils.showInformationMessage("Match field is empty.");
               f_two.requestFocusInWindow();
               return;
          model.addElement("item: " + a);
          model.addElement("match: " + b);
          model.addElement(" ");
          int size = model.getSize();
          pairList.setSelectedIndex(size - 3);
          f_one.setText("");
          f_two.setText("");
          f_one.requestFocusInWindow();
     private void editList() {
          if (pairList.getSelectedValue().toString().equalsIgnoreCase(" ")) {
               Toolkit.getDefaultToolkit().beep();
               f_one.requestFocusInWindow();
               return;
          if (!f_one.getText().equals("")) {
               int result = JOptionPane.showConfirmDialog(this,
               "The Item field contains text. Replace the text?",
               "Flash Card Activity", JOptionPane.YES_NO_OPTION,
               OptionPane.INFORMATION_MESSAGE);
               if (result == JOptionPane.NO_OPTION) return;
          if (!f_two.getText().equals("")) {
               int result = JOptionPane.showConfirmDialog(this,

          String item = "";
          String match = "";
          int index = pairList.getSelectedIndex();
          String choice = model.getElementAt(index).toString();
          if (choice.startsWith("item")) {
               item = choice;
               match = model.getElementAt(index + 1).toString();

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

It is a pity though that they desing it to work only if you select the header of the row/column. It should be enabled to work from within any cell in the table.

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]);
