我正在开发一种同步机制，将数据从 aws redshift 移动到 aurora。为了降低网络 I/O 的负载，我正在转换 redshift 上的查询并向它们添加校验和查询，这样我将仅导出已更改的记录。我用另一个 Select * 查询包装基本查询并添加校验和函数。
我尝试删除一些内部子查询，之后新查询开始工作，但我无法更改查询，因为它是由其他一些平台提供的。
基本查询：

期望获取基本查询上的所有记录和列以及校验和的另一列。
相反，我收到一个错误：
Amazon 无效操作：无法识别的节点类型：407； [SQL 状态=XX000，数据库错误代码=500310]
省略 ORDER BY 子句。这减轻了我的错误。
但是如果我想使用 order by 子句怎么办
