Update mysql when cell value is edited in JTable

Well I have a JTable in my app that fetches records from a MySql database adn displays them in a sorted order.
Till now I have been using a separate JTextArea and a JComboBox to allow the users to edit the table, something like
so whenever someone clicks on a row in the table the ID of the record is automatically updated below in a JLabel that lies before the JComboBox.
The question is how can I allow users to simply double click and edit values in the cells which would automatically fire a SQL Update query and update the same in the database. I want to allow this on certain Columns only not every Column.
A response with a code example would be highly appreciated.

You can use a TableModelListener to be notified of changes to the TableModel.
I want to allow this on certain Columns only not every Column.
The row/column is found in the TableModelEvent so you check the column that changed before invoking the SQL update.
One potential problem with this is that a TableModelEvent is generated even if the data isn't changed. That is if you place the cell in edit mode and, for instance, tab to the next cell without change the data and event will still be generated.
To get around this problem you may want to consider using the Table Cell Listener. When using this class the event is only generated if the data has actually been changed.

How to auto-refresh a JTable bound to Mysql database after insert using NetBeans

I'm working on a project in NetBeans.
I have a Jtable which i bound to my database and there is a form that I use to insert data.
I want the records in the table to be refreshed with each insert.
How can I do that?

I want the records in the table to be refreshed with each insert.
Then your "insert" logic need to do two things:
insert the data into the database
insert the data into the JTable. This is done by using the addRow(...) method of the DefaultTableModel. You get the data from the form, create a Vector to contain the data for each column then you add the Vector to the model.

I should simply select the table and go to the navigator window. Under "Other Components" there is the list that was created after the binding and contains the table records (you should know its name). Right click on the list > Properties > check "observable".

Please try the following code:
if you want update the table on button click or on event of any component
you have to put the code in the event
the list generated should be Observable checked
code
udetailsList.clear();
udetailsList.addAll(udetailsQuery.getResultList());

How to Extract Data from a JTable filled by user in Java

I have created a JTable using GUI Builder in NetBeans. It is Currently Having no data. The table is editable, and is Displayed in on a Panel. This Table is called passengerDetailsTable. Now I want users to Write data in its cells and after entering data, when they press submit, data should be extracted from table and available for processing. But I am unable to do it.
I have written sample code to do above:
TableModel tm = passengerDetailsTable.getModel();
Object o = tm.getValueAt(1,1);
System.out.println(o.toString());
This code is triggered when I press submit button.
According to me It should print the value at cell(1,1). But it gives Null pointer exception. Please help me to resolve it.

Now I want users to Write data in its cells and after entering data,
Did the data get saved to the model?
See Table Stop Editing for a way to make sure the data is save when you click a button.
If this doesn't help then post a proper SSCCE that demonstrates the problem because we don't have enough information to keep guessing what you might be doing.

Creating front-end user interactive table using MySQL as back-end

Creating front-end (Java) user interactive table using MySQL as back-end
Now im trying to create user interactive form.
Untill now, I have created a form view, using swing components, JLable, JTextfield where user enters data. JButtons, 'new' 'save' 'delete' 'edit', which listens user action through ActionListner.
A table that 'extends' AbstractTableModel. Table values are the ResultSet values. i have used MySQL connectivity.
Table is displayed. User can now add new row to it, using 'New' and 'Save' button.
My problem is, i need the corresponding TextFields to display the corresponding row user selects in the displayed table, so that 'edit' and 'delete' would be user interactive. users are allowed to select table's row. Need Help.
Im sorry if any mistake in my question format and language. Thank you!
i need code for creating table ...
ple help me on tis....

i need code for creating table
How much will you pay? :)
..i need the corresponding TextFields to display the corresponding row user selects in the displayed table..
For that you can use,
Give a button, like EDIT and in the event handler for EDIT use something like,
jTextField.setText( jTable.getValueAt(
jTable.getSelectedRow(),
jTable.getSelectedColumn())
.toString()
);
2.As an alternative you can also utilize the event in jtable like mouseClicked with the above code
Now regarding the edit and delete , you may utilize the focusLost event of the textfield or use a EDIT or DELETE button, and carryout the updation, which will be much reasonable option.

Provide two links for view and edit
of table values
In view keep the values simply in td element of table.
In edit , use input elements of type text inside td element.
If you want to do everything in same page, Ajax can be used for both view and edit.
