Re: [nhusers] Re: Subquery in From Clause

Moving this over to the development list...

>From my perspective, we have two too many ways to translate a query into SQL
already - HQL, Criteria, and NHish SQL. Each have their own codebase to
translate a query into SQL, which is bad. Imagine if LINQ translated
directly to SQL rather than via Criteria. Every new query feature would
require 4 different, divergent implementations. I've said it before, but
NHibernate really needs an AST that HQL, Criteria, and LINQ can be
translated to. I personally am not familiar enough with compiler theory to
make this happen at the moment. I know Fabio spent a lot of time on it, as
have Aaron and Oren, and it's a tough problem. I hate to re-open the AST
can-of-worms, but I think this issue must be seriously addressed in the NH
2.1 timeframe. (Then again, I've got no voting rights as I'm not a
committer. So feel free to ignore my rantings.)
