;with data as (
select p.NUMBER_, p.PARENTPROJNUMBER, p.NAME, p.Value1
from yourtable p
where p.PARENTPROJNUMBER IS NULL --- presuming this are the "root parents", or the one you are looking for ...
UNION ALL -- here is the recursive stuff
select p.NUMBER_, p.PARENTPROJNUMBER, p.NAME, p.Value1
from DATA d
JOIN yourtable p
ON p.PARENTPROJNUMBER = d.NUMBER_
AND d.PARENTPROJNUMBER <> d.NUMBER_
)
select * from data
Hi Guy
Works nice, but is it possible to sort the output like in the attached file.
Like this :
942800 -
942930 - 942800
942840 - 942800
942842 - 942840
and, output the niveua of the hierachy ?

the output is normally sorted like that.
to add the level, change like this
