I have a self-referencing table, something like:

id integer
name varchar(98)
parentid integer (references another row in the same table)

say I have these rows:
ID ParentID Name
1 <null> World
2 1 Europe
3 2 Sweden
4 2 Germany
5 3 Stockholm
6 3 Gothenburg
7 4 Berlin


Now is there a smart SQL query that for one or more id's, will return
the actual rows, including their ancestors? That is, if I do a select
"where ID=5", I would like rows 5,3,2 and 1 returned ("Stockholm",
"Sweden","Europe","World").
