I’m trying to get a form to write information to a MySQL DB. The servlet is connecting to the confirmation jsp but the database is not recording the information. I’m getting the following error message:

Based on query

String query = 
            "INSERT INTO User (fName, lName, email_address, password, dataOfBirth, phone,"
            + " address, city,  state,  country,  zipcode, accountType)"
            + "VALUES (?,?,?,?,?,?,?,?,?,?,?)";

You should use following query instead, whereby the parameters are actually 12, not 11.

     String query = 
            "INSERT INTO User (fName, lName, email_address, password, dataOfBirth, phone,"
            + " address, city,  state,  country,  zipcode, accountType)"
            + "VALUES (?,?,?,?,?,?,?,?,?,?,?,?)";

While for the set parameter,

         ps = connection.prepareStatement(query);
         ps.setString(1, user.getfName());
         ps.setString(2, user.getlName());
         ps.setString(3, user.getEmailAddress());
         ps.setString(4, user.getPassword());
         // ps.setString(5, user.getDateOfBirth());
         // ps.setString(5, user.getPhone());
         ps.setString(5, user.getDateOfBirth());
         ps.setString(6, user.getPhone());
         ps.setString(7, user.getAddress());
         ps.setString(8, user.getCity());
         ps.setString(9, user.getState());
         ps.setString(10, user.getCountry());
         ps.setString(11, user.getZipcode());
         ps.setString(12, user.getAccountType());

For the update query

    String query = "UPDATE User SET" 
                    + "fName = ?"
                    + "lName = ?"
                    + "password = ?"
                    + "dateOfBirth = ?"
                    + "phone = ?"
                    + "address = ?"
                    + "city = ?"
                    + "state_or_Region = ?"
                    + "country = ?"
                    + "zip = ?"
                    + ""
                    + "WHERE email_address= ?";

You missing a parameter as well

         ps.setString(1, user.getfName());
         ps.setString(2, user.getlName());
         ps.setString(3, user.getPassword());
         ps.setString(4, user.getDateOfBirth());
         ps.setString(5, user.getPhone());
         ps.setString(6, user.getAddress());
         ps.setString(7, user.getCity());
         ps.setString(8, user.getState());
         ps.setString(9, user.getCountry());
         ps.setString(10, user.getZipcode());
         ps.setString(11, user.getEmailAddress());
