    st.executeUpdate("insert into survey (pk_column,name ) values (2,null)");
    st.executeUpdate("insert into survey (pk_column,name ) values (3,'Tom')");
    // Primary key pk_column must be specified
    // so that the result set is updatable

    rs.close();/*from   w w w .ja  va  2  s  .  c  o  m*/
