NHibernate NamedQuery de criteriaQuery -> aide nécessaire

Question

Je suis en train de convertir une requête de critères de travail dans une requête nommée, et ne pas obtenir le droit de syntaxe. La version hql veut apparemment à la fois le params type et id spécifié.

La requête est sur une classe mappée avec ANY (ci-dessous aussi)

Quelqu'un peut-il me donner un coup de main obtenir le droit de syntaxe?

Cheers,

Critères de recherche TRAVAIL

    result = _session
        .CreateCriteria<Allocation>()
        .Add(Restrictions.Eq(propName_Resource, resource))
        .Add(Restrictions.Between(propName_StartTime, (DateTime)searchRange.Start, (DateTime)searchRange.End))
        .AddOrder(Order.Asc(propName_StartTime))
        .List<Allocation>();

                produces
SELECT this_.AllocationId as Allocati1_2_0_, this_.ResourceType as Resource2_2_0_, this_.ResourceId as ResourceId2_0_, this_.ActivityType as Activity4_2_0_, 
        this_.ActivityId as ActivityId2_0_, this_.StartTime as StartTime2_0_, this_.EndTime as EndTime2_0_, this_.PostingTime as PostingT8_2_0_ 
FROM Allocations this_ 
WHERE this_.ResourceType = @p0 and this_.ResourceId = @p1 and this_.StartTime between @p2 and @p3 ORDER BY this_.StartTime asc;@p0 = 'EMPLOYEE' [Type: String (0)], @p1 = 98304 [Type: Int32 (0)], @p2 = 3/14/2011 12:00:00 AM [Type: DateTime (0)], @p3 = 3/20/2011 11:59:59 PM [Type: DateTime (0)] 2011-03-14 Mon - 2011-03-20 Sun

ANY Mapping (qui fonctionne!)

<any name="Resource" cascade="all" id-type="System.Int32" meta-type="System.String"
     >
  <meta-value value="EMPLOYEE" class="Employee, ..." />
  <meta-value value="Facility" class="Facility, ..." />

  <column name="ResourceType"/>
  <column name="ResourceId"/>
</any>

NAMED QUERY SO FAR (ne fonctionne pas)

pense c'est la syntaxe hql mais le message d'erreur indique un manque param

....
          select a 
          from Allocation a 
          where a.Resource = :resource 
            and a.TimeRange.StartTime between :periodStart and :periodEnd
          order by a.TimeRange.StartTime
....

        return _session.GetNamedQuery("FetchByResourceForDateRange")
            .SetEntity("resource", resource)
            .SetDateTime("periodStart", searchRange.Start)
            .SetDateTime("periodEnd", searchRange.End)
            .List<Allocation>();

UPDATE

exécute combinaison mais donne la mauvaise réponse. ne peut pas dire si elle est plus proche ou plus éloigné de ce que je dois encore

          select a 
          from Allocation a 
          where a.Resource.class = :class and a.Resource.id = :id 
            and a.TimeRange.StartTime between :periodStart and :periodEnd
          order by a.TimeRange.StartTime

        return _session.GetNamedQuery("FetchByResourceForDateRange")
            .SetString("class", typeof(Resource).FullName)
            .SetInt32("id", resource.Id)
            .SetDateTime("periodStart", searchRange.Start)
            .SetDateTime("periodEnd", searchRange.End)
            .List<Allocation>();

Ok, par Fabio Maulo, dev plomb sur NHib:

"Vous devez utiliser vos valeurs méta-données pas typeof (entité) .FullName"

Donc dans mon cas ce qui suit fait la dernière hql j'avais du travail:

return _session.GetNamedQuery("FetchByResourceForDateRange")
        .SetString("class", "EMPLOYEE")
        .SetInt32("id", resource.Id)
        .SetDateTime("periodStart", searchRange.Start)
        .SetDateTime("periodEnd", searchRange.End)
        .List<Allocation>();

A plus laid bit que je l'aurais espéré, mais je vais le prendre: -)
