Re: "How do I ..." SQL question

  Return only four rows beginning at second row:

Is this :
SELECT DISTINCT place FROM a,(
SELECT count(*) AS count, name, year FROM a   GROUP BY name, year   ORDER BY count DESC, name ASC   LIMIT 4 OFFSET 1
) as foo WHERE name=foo.name AND year=foo.year
Problem with this approach is that you'll have to run the query twice,  
one to get the hitlist by user, one for the places...
