hello, everybody!

is it possible to create a criteria for the statement below???

SELECT p.statecode AS Vater, s.statecode AS Nachfolger
FROM processstate p, processstate s
WHERE s.lft BETWEEN p.lft AND p.rgt
AND s.statecode = 'D225'
ORDER BY p.lft;

i have problems to assign one table two aliases and to select the same
column twice with two different aliases!!!
