长话短说。我有数据试图通过地址识别重复记录。地址可以在[Address]上匹配或 [Remit_Address]领域。
我使用 JOIN 和 UNION 来获取记录，但我需要匹配的记录在结果中相互显示。
我无法按任何现有字段排序，因此典型的“ORDER BY”不起作用。我查看了 RANK正如某人所建议的那样，它看起来可能有效，但我不知道如何进行分区，而且我认为 Order 给了我与 ORDER BY 相同的问题。 .
如果 RANK 不是最佳选择，我愿意接受其他想法。最终的目标是以某种方式对匹配的记录进行分组。
这是设置:

最佳答案
此查询创建所需的结果。
with cte as (
select s2.NewAdd grp, s1.*
, rank() over(partition by Supplier_No order by s2.NewAdd) rnk
from sample_data s1
inner join dupe_addresses s2 on
(s1.cleanAddress=s2.newAdd) or (s1.cleanRemit_Address=s2.newAdd)
)
select c1.*
from cte c1
where rnk = 1
order by c1.grp
OR 组合了两个连接条件反而。因此可以找到同时具有这两个条件的记录。
rank()用于计算结果集分区内每一行的排名。partition by Supplier_No用于识别重复记录。最后，使用
where rnk = 1不重复地查看记录组。
