You can do queries like this in MySQL:

    SELECT id, parent_id, name
    FROM   Tree t1, Tree t2, Tree t3
    WHERE  t3.name = 'Carp'
    AND    t2.id = t3.parent_id
    AND    t1.id = t2.parent_id

    6  0  Animal
    9  6  Fish
    14 9  Carp

Is that what you're calling recursive subqueries? or something else?
