在SQL查询中获取意外的令牌错误

Question

String query3 = "SELECT TOP " + importStockList.getOrderQuantity() +" IServe.ID FROM IServe WHERE "
            + " ExpireDate >= '" + sqlDate + "' " + " AND TelcoID = '" + importStockList.getTelcoId()
            + "' AND ProductID = '" + importStockList.getProductId() + "' AND " + "RechargeAmt = '"
            + importStockList.getRechargeAmt() + "' AND Available = 1 ORDER BY ExpireDate, SN" ;

    Session hbsessionSQL = HibernateUtilSQL.getSessionFactory().openSession();
    List<Iserve> iserve = hbsessionSQL.createQuery(query3).list();

您能帮我解决这个错误吗？我被困在这里

try {
    Session session = HibernateUtilSQL.getSessionFactory().openSession();
    Connection conn = session.connection();
    String sql = "SELECT ID FROM IServe WHERE ExpireDate >= ? AND TelcoID = ? AND ProductID = ? AND RechargeAmt = ? AND Available = 1 ORDER BY ExpireDate, SN LIMIT ?";
    PreparedStatement ps = conn.prepareStatement(sql);
    ps.setDate(1, sqlDate);
    ps.setInt(2, importStockList.getTelcoId());
    ps.setInt(3, importStockList.getProductId());
    ps.setInt(4, importStockList.getRechargeAmt());
    ps.setInt(5, importStockList.getOrderQuantity());
    ResultSet rs = ps.executeQuery();

    while(rs.next()) {
        // process result set here
    }
}
catch(HibernateException e) {
    e.printStackTrace();
}
