Wie wähle ich mit MySQL den Abfrageergebnisrang einer bestimmten Zeile aus?

von artfulsoftware :

SELECT p1.id, p1.name, COUNT( p2.name ) AS Rank
    FROM people p1
    JOIN people p2 
    ON p1.name < p2.name
    OR (
         p1.name = p2.name
         AND p1.id = p2.id
    )
GROUP BY p1.id, p1.name
ORDER BY p1.name DESC , p1.id DESC
LIMIT 4,1
