SQL Statement based on JCombobox selection

[imabutcher]

Here is the actionMouseClic ked. It should be able to update the selected row with new data from a form.
The updating works for the most part I.e It updates all data in one column to the same data (which is fine as long as I can get the SQL to work)

I need it so the SQL statement recognizes the ComboBox selection and updates the database accordingly.

   
private void addBtnMouseClicked(java.awt.event.MouseEvent evt) {                                    
                   
        String CBox2 =(String)comboBoxCS.getSelectedItem();        
        
        String sql = "update carstock set CarStock = ? where DriverID = ('CBox2')";
        
        try{
            pst = conn.prepareStatement(sql);
            pst.setString(1, addRemove.getText());
            
            
            pst.executeUpdate();
            JOptionPane.showMessageDialog(null, "Updated");        
            UpdateJTable();
        }
        catch (Exception e){
            JOptionPane.showMessageDialog(null, e);
        }
    
    }

Add an ActionListener to your combobox then in the actionPerformed method do

if(e.getSource() instanceof JComboBox) {
 JComboBox cb = (JComboBox)e.getSource();
 String selectedValue= (String)cb.getSelectedItem();
//do something with the selected value
}
