Drew,

I'm not sure how to write the ISNULL version.. This syntactically incorrect version I came up with is:

SELECT a.Address_pk, a.[Address],

STUFF(a.[Address], ss.search_idx, LEN(ss.search_val), ss.PostalServiceStandardSuffixAbbreviation) AS AddressAbbreviated

FROM [Address] a

OUTER APPLY (

SELECT TOP (1) *, LEN(a.[Address]) - LEN(txt.search_val) - NULLIF(CHARINDEX(REVERSE(txt.search_val), REVERSE(a.[Address])), 0) + 2 AS search_idx

FROM (

SELECT (ISNULL((SELECT ss.PrimaryStreetSuffixName, ss.CommonlyUsedStreetSuffixOrAbbreviation, ss.PostalServiceStandardSuffixAbbreviation

FROM StreetSuffix ss),

SELECT a.[Address], a.[Address], a.[Address]))

) ss

CROSS APPLY ( VALUES (ss.PrimaryStreetSuffixName), (ss.CommonlyUsedStreetSuffixOrAbbreviation) ) txt(search_val)

ORDER BY search_idx DESC, LEN(txt.search_val) DESC

) ss

ORDER BY a.Address_pk;

doesn't compile.

The Union ALL option scales well with 200,000+ addresses to parse, and with almost everything looking great a few addresses seem to cause troubles. I had to add some street suffixes to illistrate along with additional addresses. But the end result is Boulevard comes out BoulevaRD and Avenue East shows up as Avenue EaST (West has the same issue)

The issue I haven't been able to reproduce has the output with DRIVe instead of DR, but all the examples I provided that didn't work in a bigger sample of suffixes and addresses work in the smaller sample.

Before I drop in the next samples, I wanted to say thanks and I'll mark this the solution, since it will address 99% of the duplication issues and the rest we can deal with. It would be nice to see a solution that will work for everything thought, or 99.9%!
