需要按ReleaseTime ASC排序，然后按该ID的所有PurchaseTime ASC排序。结果应如下所示：

有什么建议吗？提前谢谢

如果我理解正确，您希望按每个
id
的最短发布时间排序，然后按购买时间排序

您可以按顺序使用窗口功能：

order by min(releasetime) over (partition by id),
         id,
         purchasetime asc

谢谢戈登！很高兴您能从这个非格式化的表中理解它（对不起！），这让我更好地理解了“partitionby”子句，并且我能够将它应用到两个类似的问题上Hanks Gordon！很高兴您能从这个非格式化的表中理解它（对不起！），这使我更好地理解了“partitionby”子句，并且我能够将它应用于两个类似的问题：您使用的是哪个数据库？您使用的是哪个数据库？
