Hello everyone,

I am taking an interesting error message. I couldn't find a solution. I want to update some fields in database via textbox.

private void btnUpdateActionPerformed(java.awt.event.ActionEvent evt) {                                          
        try {
            //1.Kısım Baglantı Saglıyoruz
            this.host = "jdbc:derby://localhost:1527/EMRE";
            this.Name = "emre";
            this.Pass = "2561";
            Connection con = DriverManager.getConnection(host,Name,Pass);
             
            //2.Kısım Statement Olusturuyorum
            
            Statement cumle = con.createStatement();
            String query = "SELECT * FROM P_LOGIN";
            ResultSet rs = cumle.executeQuery(query);
            
            while(rs.next())
            {
            rs.updateString("SIFRE", txtAddUserPassWord.getText());
            rs.updateString("KULLANICI_ADI",txtAddUserName.getText());
            rs.updateString("ROLE",cmbAddUserRole.getSelectedItem().toString());
            JOptionPane.showMessageDialog(null,txtAddUserName.getText()+ "has been updated" );
            
            
            }

Everything is ok but at runtime I am taking an error which is;

"Update String Not Allowed because Result Set is not an Updatable Result Set"

Do you have any solution?
