Long Story short. I have data that I'm trying to identify duplicate records by address. The address can be matched on the [Address] or [Remit_Address] fields.
I use a JOIN and UNION to get the records, but I need the matched records to appear with each other in the results.
I can't sort by any of the existing fields, so a typical 'ORDER BY' won't work. I looked into RANK as suggested by someone and it looks like it might work, but I don't know how to do the Partition, and I think the Order gives me the same issue with ORDER BY.
If RANK is not the best option I'm open to other ideas. The goal ultimately is to group the matched records someway.
Here is the setup:

order by c1.grp
removed the Union , and combine two join Conditions by OR instead.
so a record with both conditions may be found.
The rank() is used to calculate a rank for each row within a partition of a result set.
partition by Supplier_No used to To identify duplicate records.
finally, use the where rnk = 1 to see the group of records without repetition.
