Thanks Luke and Brian.
I know that the SQL below works with MySQL v4 so I'd like to be able to
issue it directly. Is it possible to somehow pass the raw SQL and get a
DBIx result set returned?

I'm trying to figure out how to perform subqueries with DBIx::Class. For
example, I want to find all the roles that user 2 hasn't been assigned.
The standard SQL is
select role_id, display_name
from app_role a
where not exists
from user_role u
where u.user_id = 2
and u.role_id = a.role_id);
What would the DBIx::Class equivalent be?
Sadly subselects like this aren't possible with DBIC at the moment.
It's definitely on the TODO list, I guess Matt will be able to tell you
roughly when it'll be ready. Until then you'll have to find a way of doing
it that doesn't require the subselect.
