  What is better to return, what is correct, if not null?
  
  

  public User getEmailByName(String name) {
  
          try {
              String sql = "SELECT email FROM user WHERE name=?";
              return jdbcTemplate.queryForObject(sql, new EmailByNameMapper(), name);
  
          } catch (EmptyResultDataAccessException e) {
              return null;
          }
      }

  
  
  

  public class EmailByNameMapper implements RowMapper<User> {
  
      public User mapRow(ResultSet resultSet, int i) throws SQLException {
  
          User user = new User();
          user.setEmail(resultSet.getString("email"));
          return user;
      }
  
  }
