        PreparedStatement ps = null;
        con = ConnectionFactory.getConnection();
        String sql = "insert into sd0703_account(id, no, pwd,owner, balance, cdate)";
        sql += " values(?,?,?,?,?,?)";
        
        account.setId(IdGenerator.nextId());
        ps = con.prepareStatement(sql);
        
        int index = 1;
        ps.setInt(index++, account.getId());
