create a clone of your table but make your "key" duplicated column as a unique 
key setting the index to "ignore duplicate keys". then do a SELECT/INSERT

INSERT clonedTable...
SELECT ...
FROM tableWithDuplicates

the db server will toss out all the duplicated rows leaving the first inserted 
one intact.

btw this is for sql server.
