0.7 has support for window functions. I haven't tried it in a subquery.

I have the following statement :
SELECT name, id, division, value,

SELECT name, id, division,value, max(value) over
(partition by division) as max_val
FROM tab1
)
WHERE value = max_val
I try to turn this sql statement into a Query object
I tried this
sqlquery=session.query(sometab)
sqlquery.statement= SQL QUERY GIVEN ABOVE
but it does not work because statement cannot be set directly.
What is get-around for this?
Can this statement be written as a subquery? If yes, how? I saw
several example of subqueries on the internet but none of these seem
to be suitable for this statement.
Thanking in advance
