Amazon redshift 错误消息为[Amazon]（500310）无效操作：由于内部错误，不支持此类型的相关子查询模式

这就是问题所在

请建议任何替代方法来替换此查询。

错误是因为

子句中的查询不存在

子句引用了该子句外部的表。将

notexists

子句转换为带有谓词的

LEFT JOIN

，以排除任何匹配项。这种模式通常被称为“反连接”

当前：

FROM (…) a
WHERE NOT EXISTS (SELECT 1
                   FROM dw_prestage.check_fact_insert aa
                   WHERE aa.transaction_id = a.transaction_id
                     AND  aa.transaction_line_id = a.transaction_line_id)

重写：

FROM (…) a
LEFT JOIN dw_prestage.check_fact_insert aa
       ON a.transaction_id = aa.transaction_id
      AND a.transaction_line_id = aa.transaction_line_id
WHERE aa.transaction_id IS NULL

请整理以使其可读。顺便说一句，此查询在mysql中不起作用，因为mysql不支持MINUSMySQL没有

减号
运算符。
