I have a table that has addresses
I need to delete the duplicates. I know there is a duplicate if the 'street' is exactly the same. I need to keep ONE of the rows that are duplicate, if there are no duplicates leave the record as is.

table = addresses
field = street

I tried this but did not work out:

DELETE FROM [Addresses] WHERE [Street] IN (
    SELECT id FROM [Addresses] GROUP BY id HAVING ( COUNT([Street]) > 1 )
)
