nhibernate

hi all. I have the following query which I would like to write using the criteria api of NH.

select status, count(1) from (select distinct Status, post_id from post_statistics) tbl group by status

each post_id can exist multiple times in post_statistics

e.g.

id post_id status 1 1 open 1 1 edit 1 1 open 1 2 open

so the query should return the following results:

status count open 2 edit 1

thx in advance.
