Castle/ Active Records: How do you count objects?
I'm trying to do a simple "Select Count(*) from PRODUCTS where date > xxx" with Castle on NHibernate.
If I was directly using NHibernate, I could reuse this question answers but unfortunately I see no easy way to access the Current NHibernate session from Castle Records.
I obviously don't want to retrieve all my objects and do a Count on the C# side ;). I only need to know how many objects there are.
There are many ways to do this, the simplest is:
or your could use CountQuery, HQL, etc, there are many alternatives.
UPDATE: for NHibernate 2.0+ it's Restrictions instead of Expression.
I'll copy common questions like these to the ActiveRecord wiki.
