RE: Delete Duplicate Rows

That solution looks appealing but I think it'll generate duplicate rrns in
some cases and possibly cause problems for the delete.
Try this alteration:

DELETE FROM myLib/myFile d 
WHERE  RRN(d) IN                         
  (SELECT RRN(b) 
   FROM   myLib/myFile b, 
          (SELECT a.f1, MIN(RRN(a)) minrrn 
           FROM myLib/myFile a 
           GROUP BY a.LastName) AS c

   WHERE  b.LastName = c.LastName AND RRN(b) > c.minrrn)

That's interesting...the first SQL statement (the SELECT) shows a bunch
of dup rows, the second SQL statement (the DELETE) says no rows found.
