如何通过以下示例构建逻辑以查找红色和琥珀色记录的历史记录

以下结果显示在屏幕截图中

当我运行查询时，被圈出的“绿色”不应该出现，因为我想获取红色和琥珀色的历史记录。我可以将绿色记录作为历史的一部分，但不是在开始时或最近几个月内

以下是我想要实现的目标

Answer 1

这是一个可能的查询的大纲：

使用窗口函数发出子查询，按年月分区，按年、月、pk_key升序排序选择最低的pk_key，并为每个分区选择第一个结果。 然后将结果与where 子句和第二个约束结合使用：

... where not(pk_key in (first_query.pk_key) and metric_results_status = 'GREEN')

抱歉，我无法提供更具体的信息，因为您提供的详细信息并不清楚您的数据库结构实际上是什么样的。

愿上帝怜悯你的灵魂！
