DELETE FROM <table> a
WHERE a.rowid > (SELECT MIN(b.rowid)

                                      FROM table b
                                      WHERE b.key_field1 = a.keyfield1
                                      AND b.key_field2 = a.keyfield2
                                      AND b.key_fieldN = a.keyfieldN);

Be certain to include all fields in WHERE clause that make up a unique record.
