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,
Berryl
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>();
La solution
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: -)
HTH,
