How could I replace the HQL query below using QueryOver API?
var sql = "from Role r, Action a where r.Active = :active and a.Active = :active";
var result = manager.Session.GetISession().CreateQuery(sql)
.SetBoolean("active", true).List();
I don't believe there's a way to do this in QueryOver, since both JoinAlias
and JoinQueryOver
require an expression describing a path to the related entity.
However, this is easy to accomplish in LINQ-to-NHibernate:
var result =
(from role in manager.Session.GetISession().Query<Role>()
from action in manager.Session.GetISession().Query<Action>()
where role.Active == true && action.Active == true).ToList();
With NH 3.2, here's the SQL I get:
select role0_.Id as col_0_0_,
action1_.Id as col_1_0_
from [Role] role0_,
[Action] action1_
where role0_.IsActive = 1 /* @p0 */
and action1_.IsActive = 1 /* @p1 */
