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

Return only four rows beginning at second row:
>
> SELECT count(*) AS count, name, year FROM a
> GROUP BY name, year
> ORDER BY count DESC, name ASC
> LIMIT 4 OFFSET 1;
>
> count name year

> 2 bob 2003 w,e

> 2 sue 2004 s,w

> Select only places visited included in LIMITed query:

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...
