The simplest way to eliminate the duplicate records is to
SELECT DISTINCT into a temporary table, truncate the
original table and SELECT the records back into the original
table. That query looks like this:
select distinct *
into #holding
from dup_authors
truncate table dup_authors
insert dup_authors
select *
from #holding
drop table #holding
