Just solve the thing with a cursor
like
declare del_dups cursor
for
select * from <table_name>
group by column_name
having count(*) > 1
(column_name where the duplicates are)
open del_dups
fetch next from del_dups into ......
while @@fetch_status <> 0
begin
delete from table_name where current of cursor
fetch next from del_dups into ....
end
close del_dups
deallocate del_dups
For the update you should change te delete statement to
update table_name set ... = .... where current of cursor
