id timestamp status 1 2019-10-20 12:34:56.000 approved 1 2019-10-22 12:34:56.000 approved 2 2019-10-20 17:34:56.000 approved 2 2019-10-21 12:34:56.000 approved 3 2019-10-23 18:10:10.000 mod_in_ip 3 2019-10-24 11:10:10.000 approved 3 2019-10-24 12:10:10.000 approved 4 2019-10-25 12:10:10.000 approved 4 2019-10-25 18:10:10.000 approved
我想将id标记为 new 或 edited 。问题是从5pm到5pm的记录中被认为是工作时间段， 即从 ‘2019-10-25 17:00:00’到‘2019-10-26 17:00:00’被认为是工作时间段 或昨天的下午5点到今天下午5点是一个工作时间。
例如：如果您查看表格并获得预期结果，则带有昨天6:00 PM记录和今天11AM记录的id记录应标记为new。
预期结果/结果应为
1 edited 2 new 3 new 4 edited
最初我尝试过此方法，但它无法解决上述问题
select id, case when count(id)<=1 then 'New' else 'Edited' End AS prefix from(select id,status ,trunc(timestamp) from table where status='approved' and id in (1,2,3,4) group by id,status,trunc(timestamp)) group by id
结果是
1 Edited 2 Edited 3 new 4 new
但预期结果是
我正在寻找解决方案，例如 从5pm到5pm 的 innerquery组记录， 以便外部查询可以正常工作，或者完全不同的解决方案也是可行的

如果要将5pm到5pm视为“同一”天，可以很容易地将Oracle日期向前或向后移动一天的时间（例如，可以将5pm向前移动7小时以成为“下一个”的开始）天）
