Joining to Derived Tables

How can I join to a derived table?
My derived table would look like...
(SELECT file_id,
MAX(DATETIME) AS MAXDATE
FROM DataTrac.dbo.NOTES
WHERE group_id = 'SRV'
GROUP BY file_id) MAXDTTM
and I would need to LEFT OUTER JOIN from a table called GEN matching by
file_id. A LEFT OUTER JOIN because I may not have SRV Notes for a GEN row.
Let me know...
Thanks!Try,
select ...
from gen as a left join (select ... from DataTrac.dbo.NOTES) as b on
a.file_id = b.file_id

select ...
from
gen as a
left join
(select ... from DataTrac.dbo.NOTES ...) as b -- here goes the derived
table
on a.file_id = b.file_id
