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 上的查询并为它们添加一个校验和查询，这样我将只导出已更改的记录。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，之后新查询开始运行，但我无法更改查询，因为它是由其他平台提供的。
基本查询:
select x.player_id as playerid,
p.player_nickname,
r.region_code,
s.title as season_name,
x.rating as ranking_score,
x.rank_no as rank_no,

预期获取基本查询中的所有记录和列以及校验和的另一列。
相反，我得到一个错误:
亚马逊无效操作:无法识别的节点类型:407； [SQL 状态=XX000，数据库错误代码=500310]
最佳答案
省略 ORDER BY 子句。这减轻了我的错误。
关于sql - redshift 无法识别的节点类型 407，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/57856121/
