"Getting a particular Result Set"

[Ragh Kumar Singh]

I have a database in access.One of its table has 5 columns.Out of that only one column is unique(not by design).But during some manual updation of that table some of the rows got duplicated.I want to get those rows in my result set for which that particular column(and hence the whole row got duplicated) by quering the database.
Could u plz suggest a suitable querry for the same.
