Problem in deleting a row

hi,
I have a table with set of values. added three buttons below that in table. add row, delete row, save.
if I delete the row and save and if i come again to that application still that deleted row remains. what might be the problem?

you can use flag in your internal table,
when you press delete button after selecting the particular row, set the flag for this entry in itab.
now in save event loop through the table checking flag, and delete enteries. now bind the table again by the itab.
you can do the same thing in delete button event also,
if not solved, please explain more

Problem of deletion of rows in jtable, table refreshing too

Hi,
I have a table with empty rows in the beginning with some custom properties( columns have fixed width...), later user would be adding to the rows to this table and can delete, I've a problem while deleting the rows from table,
When a selected row is deleted the model is also deleting the data but the table(view) is not refreshed.
Actually i'm selecting a cell of a row, then hitting the delete button.
So the model is deleting the information, but i'm not able to c the fresh data in table( especially when the last cell of last row is selectd and hit the delete button, i am getting lots of exception)
Kindly copy the below code and execute it, and let me know,

Hi,
I've got the solution for it. As when the cursor is in cell of
a row and hit the delete button, the data in that cell is not saved,
So i'm trying to save the data first into the model then firing the action event by doing this ..
jButton2.addActionListener( new ActionListener(){
public void actionPerformed(ActionEvent actionEvent){
// If a button press is the trigger to leave a JTable cell and save the data in model
if(jTable1.isEditing() ){
String text=((javax.swing.text.JTextComponent)jTable1.getEditorComponent()).getText();
jTable1.setValueAt(text,jTable1.getSelectedRow(),jTable1.getSelectedColumn()) ;
jTable1.getCellEditor().cancelCellEditing();
// HERE DO THE DELETE ROW OPERATION

JTable problem when deleting all rows and reinserting data,

Hi,
I have a JTable with an AbstractModelTable.
Some cells in the JTable have a custom cell editor. I am using
the cell editor that accepts only numeric values as explained in
the JTable tutorial (WholeNumberField).
- The JTable gets filled by choosing a value from a JList
for example:
1- choose a customer name from the customer JList
2- gets the customer order (database)
3- fills the Jtable with the customer data.
- When a customer is chosen from the Jlist I call a function
inside my table model. (This function removes all rows, clears the vector holding the data and calls fireTableRowsDeleted (firstRow, lastRow));
- Then I fill up the new data for this customer.
All of this works fine, except if I have entered a new value inside
one of the cell that has a customed cellEditor (ex: the Ordered column).
for example : user enters number 20 in the "ordered" column for customer A. Then changes his mind and chooses customer B from the JList. So the JTable gets cleared and refilled with the data of Customer B but the column "ordered" still has the value '20'
I would really appreciate any help...
Thanks

Don't know is this will work, but try the following before updating the table:
if (table.isEditing())
table.removeEditor();Also, why do two TableModelEvent's..one for all getting deleted, one for the new filling. You could do one fireTableDataChanged after the new data is in.

Problem in deleting the rows in a table

I am trying to delete 1213 records from a table.
When I am selecting the rows are selected within seconds.
When I am trying to delete the same rows, the script hangs, can anybody, help in finding the issue here!

Or that there are some foreign keys defined without indexes that are forcing Oracle to do 1213 full table scans on some large child table to ensure that the data you're deleting isn't referenced by some other row.

How to delete a row in the table in servlets

I have met a problem in deleting a row in table using servlets.
My table looks like this:
ID Name Type
12 Milienium S
15 USIA O
My code looks like this:
String query = "SELECT * FROM tb_Funds";
rs = statement.executeQuery(query);
while(rs.next()) {
StdID=rs.getString("FundID");
StdName=rs.getString("Name");
StdType=rs.getString("Type");
out.print("<td><INPUT TYPE=TEXT NAME=
myName VALUE=" + StdID + "></td>");
out.print("<td>" + StdName + "</td>");
out.print("<td>" + StdType + "</td>");
buf.append("<td>" + "<INPUT TYPE=SUBMIT
NAME=Delete VALUE=DELETE>" + "</td></tr>");
There is a delete button in every row. May I know how to delete the row that I want by getting the ID from the table and delete it from the database.

Deleting from a table is simple -> delete from tb_funds where id = <value>. Obviously replace <value> with the appropriate ID or use a bind variable (a ?) and prepared statements.
Are you asking how to pass the id associated with the table row from the browser when the button is pressed?

Problem with delete operation

Hi all,
Jdev version(11.1.1.3.0)
I have a <af:table> with a check box.I can select the rows
by checking check box and delete those rows.
Sometimes am facing a problem in deleteing the rows.
The viewobject that binded to the table,is based on two
Entity Objects A&B.The table B has no primary key field.But
it has a dynamic row_id as key fileld.
The problem is am not able to filter
the query results,when I select dynamic "Row_Id" in the select
query,I can't filter the records.(In the VO if I unselect the ROW_Id,
got an error like"Row_id missing in the view oject")Because of
this issue am not able to delete the records.Due to
this problem,delete works only in random.
Please share the ideas..
Thanks
Swapna

Try selecting a different attribute for EntityB as a key field

Problems deleting current row

Hello,
I have got the following problem. I have got a table with data from my database. And a dataprovider to fetch the data from my rowset. I have got a button in each row of this table where i can get details or delete the corresponding row.
But when i click delete he wont delete the row correct. After a while i realised that the always fetch the same row. I dont understand why because i took the same code as it was used in the tutorial. For control i made a variable to remember the id of the fetched row but it wont change after the first "delete". Can somebody tell me why he wont change the value?
public String l�schen_action() {
try {
RowKey rowKey = tableRowGroup1.getRowKey();
int id = getSessionBean1().getMaxappid().parseInt(applikationDataProvider.getValue("APPID", rowKey).toString(), 10);
getSessionBean1().setTemp(id);
if(rowKey != null && applikationDataProvider.canRemoveRow(rowKey)){
applikationDataProvider.removeRow(rowKey);
applikationDataProvider.commitChanges();
applikationDataProvider.refresh();
} catch (Exception e) {
log("Fehler beim L\366schen des Eintrags", e);
error("Exception deleting row: " + e);
} // end try catch
return null;
Thanks in advance for help

Problems to delete Rows

Hi,
i want to delete all rows in a table which will be automaticlly updatet in a thread. the problem is that i get somtimes the message 9>=9 or 8>=3. did somebody know what that means ?!?

it means the row index that you are trying to remove doesnt exist.
9>=9 means that you are trying to remove row index 9 in a table that has only 9 itmes (remember its zero based)
there's probably something dodgy with you remove code.
off the top of my head try looping through with (rowcount - 1)

Problem in Delete Row

Hai To All,
         Iam using PL 05 i have enable DeleteRow option. If i click the deleterow the row is deleted but after saving the entry there is null value in database. for example if i have 2 row in the matrix if i delete last row the content is deleted after that iam saving the matrix. In the database i have 2 rows one with content and other with null value..
Whts the soultion of this....
Does anyone have idea reply me....
Regards,
Anitha

Hi Anitha,
For the delete option, you need to right a small function if its going to be ur own form.
Try using the following code...
Private Sub DeleteRow()
        Dim oDBDSource As SAPbouiCOM.DBDataSource
        Dim Count As Integer
        Dim oMatrix As SAPbouiCOM.Matrix
        Try
            oDBDSource = objForm.DataSources.DBDataSources.Item("@TableName")
            oMatrix = objForm.Items.Item("3").Specific
            oMatrix.FlushToDataSource()
            oMatrix.DeleteRow(strRow)
            objForm.Update()
            'objForm.DataSources.DBDataSources.Item("@TableName").RemoveRecord(strRow - 1)
            oDBDSource.Clear()
            oMatrix.FlushToDataSource()
            oMatrix.LoadFromDataSource()
            For Count = 1 To oDBDSource.Size - 1
                oDBDSource.SetValue("Code", Count - 1, Count)
            Next
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
    End Sub
Hope this helps.

Problem in deleting row from database in table component

Hi,
I have a table component that its content change by diffrent links.
in this table i have a hyperlink in each row to deleting that row from dataBase.
so i must get the current row .
i do it like this:
define a rowset in the page that have a delete query :
delete from response where responseID=?
in action of delete hyperlink ,i have:
Integer responseId=(Integer)responseDataProvider.
getValue("#{currentRow.value['responseID']}") ;
getSessionBean1().getResponseRowSet().setObject(1,responseId);
getSessionBean1().getResponseRowSet().execute();
but in first line occure a exception:
illigalArgument #{currentRow.value['responseID']}
thanks.

by using data table
first you should get current record (row that recived action)
then delete it by using data provider.
I do not think that you could execute delete statement using rowSets because they just can provide Select statements.
btw , following code will retrive clicked row from data table and
delete that row
try {
RowKey rk = getTableRowGroup1().getRowKey();
if (rk != null) {
testDataProvider.removeRow(rk);
testDataProvider.commitChanges();
} catch (Exception ex) {
log("ErrorDescription", ex);
error(ex.getMessage());

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.

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
