On SQL 2005 you can use:

SELECT a.appartmentid,
substring(x.CodeList, 1, len(CodeList) - 1)
FROM appartment a
CROSS APPLY (select l.code + ',' AS [text()]
from appartmentlistvalue alv ond
join listvalue l on alv.listvalueid = l.listvalueid
WHERE alv.appartmentid = a.appartmenti
ORDER BY a.appartmentid
FOR XML PATH ('')) AS x(CodeList)

The syntax is a bit obscure, but it works.

On SQL 2000, you cannot do this in a single SQL statement, but you need to
run a cursor to build the lists. You may be better off to compose the
lists in the client layer.
