here's a little bit of help. since you cannot determine whether a cityname has 1,2, or more words, i can't see of any way to not do at least a portion of this manually.

i would hope that something like this might get you 90% of the way done automatically.

as i see it, you need to pull bot cityname and state out as separate columns.

create table #tmp(addr1 varchar(80))

insert into #tmp (addr1) values('20 Kenvil Ave Succasunna NJ')

insert into #tmp (addr1) values('327 Aspen Ct stanhope NJ')

insert into #tmp (addr1) values('22 Woodland Dr Long Valley NJ')

insert into #tmp (addr1) values('4 Brittin St Madison NJ')

insert into #tmp (addr1) values('18 North 1 Ave Kenvil NJ')

insert into #tmp (addr1) values('C/o Abe Mishkin 22 Swamp Fox Dr Carolinea Shore NC')

insert into #tmp (addr1) values('Paragon Village 425 Rte 46 E.#314 Hackettstown NJ')

insert into #tmp (addr1) values('1 Chestnut St. Netcong NJ')

alter table #tmp add cityname varchar(80),state varchar(2)

--find the space that is second from the end of the string

--extract the state:

select REVERSE(SUBSTRING(REVERSE(addr1),1,charindex( ' ',reverse(addr1))-1)) from #tmp

update #tmp set state = REVERSE(SUBSTRING(REVERSE(addr1),1,charindex( ' ',reverse(addr1))-1))

--single word citys/towns:

select REVERSE(SUBSTRING(REVERSE(addr1),3,charindex( ' ',reverse(substring(addr1, 1, len(addr1) -3)))+0)) from #tmp --where count of spaces =4?

update #tmp set cityname = REVERSE(SUBSTRING(REVERSE(addr1),3,charindex( ' ',reverse(substring(addr1, 1, len(addr1) -3)))+0))

--doubleword city's towns?

--triple word cities like New York City?

select * from #tmp

Actually, looking at the sample data provided, you do have a couple of identifiers.

Identifier 1) ST, DR, CR, etc...

There are a finite amount of street identifiers, even if you have E.#314.

Identifier 2) Reversing the identifier to the END of the string, being the 2 letter state, plus one space.

Personally depending on the amount of records involved, it may just be as easy to export this to excel, and work with find, and mid functions.

If you want to explore this option, reply to me.

here's a couple of other ideas that might help:

if we can assume that single-word city/towns have all address elements, so there is always 4 spaces in the document,something like this might help:

select len(addr1) - Len(replace(addr1,' ','')) as NumSpaceOccurances, #tmp.* from #tmp

select REVERSE(SUBSTRING(REVERSE(addr1),3,charindex( ' ',reverse(substring(addr1, 1, len(addr1) -3)))+0)) from #tmp where len(addr1) - Len(replace(addr1,' ','')) =4

--using this instead of the previous example leaves the cityname null for later updates:

update #tmp set cityname = REVERSE(SUBSTRING(REVERSE(addr1),3,charindex( ' ',reverse(substring(addr1, 1, len(addr1) -3)))+0)) where len(addr1) - Len(replace(addr1,' ','')) =4

select len(addr1) - Len(replace(addr1,' ','')) as NumSpaceOccurances, #tmp.* from #tmp

NumSpaceOccurances	addr1	cityname	state
4	20 Kenvil Ave Succasunna NJ	Succasunna	NJ
4	327 Aspen Ct stanhope NJ	stanhope	NJ
5	22 Woodland Dr Long Valley NJ	NULL	NJ
4	4 Brittin St Madison NJ	Madison	NJ
5	18 North 1 Ave Kenvil NJ	NULL	NJ
10	C/o Abe Mishkin 22 Swamp Fox Dr Carolinea Shore NC	NULL	NC
7	Paragon Village 425 Rte 46 E.#314 Hackettstown NJ	NULL	NJ
4	1 Chestnut St. Netcong NJ	Netcong	NJ

yet another thought: if you have the zipcode you could just look up the city and state from a separate table and ignore parsing the addr field ...plenty of free resources of zipcodes with around 42K of zipcodes in em; bigger data sources cost real money. that might be a possibility too.
