Vivek,

one question - are the rows idententical in all columns - which means is it a multiset table?

You might try the following - I can't verfiy currently on my own:

     delete from big_table
     where (field list,row_id) in
            (select field list,row_id
             from big_table
             group by field list
            qualify csum(1,field list) > 1
            )
     ;

I am not sure if it is row_id or rowid..
