使用带有下面参考和日期列示例的单个表,如何生成下面的输出以拆分行号。同一天的同一引用应显示为相同的行号。
以下示例;
MAINFRAJOB SyncDate Row Number
7861 02/10/2019 1
7861 02/10/2019 1
7861 03/10/2019 2
1045679 25/09/2019 1
10233649 03/10/2019 1
10233652 04/10/2019 1
10233652 04/10/2019 1
10233652 06/10/2019 2
123456789 02/10/2019 1
123456789 02/10/2019 1
123456789 03/10/2019 2
123456789 04/10/2019 3
我已经尝试过了,但是没有产生正确的结果;
ROW_NUMBER()over(partition by cast(ard.SyncDate as date), ard.actionref order by cast(ard.SyncDate as date) desc) AS 'RowNo'
感谢您的指导。

请改为尝试DENSE_RANK,您还需要从分区中删除日期,否则每次更改日期时该分区都会重置为1:
DENSE_RANK()over(partition by cast(ard.SyncDate as date), ard.actionref order by cast(ard.SyncDate as date) desc) AS 'RowNo'
