分离的crteria nhibernate

问题描述

如何使用Detached crteria nhibernate进行以下查询

Hi,How to do below query using Detached crteria nhibernate

SELECT
(SELECT COUNT(id) FROM Employees WHERE YEAR(hire_date)=2011) as hirecnt,
(SELECT COUNT(id) FROM Employees WHERE YEAR(termination_date)=2011)as termcnt

我这样做但它不起作用...这里我用它来显示mvc图





string employmentstatus =终止;









DetachedCriteria criteria1 = DetachedCriteria.For< launchpad>（）



.Add（Restrictions.Eq（Projectio） ns.SqlFunction（year，NHibernateUtil.Date，Projections.Property（Hire_Date）），2013））

.Add（Restrictiontions.Eq（Projections.SqlFunction（year，NHibernateUtil。 Date，Projections.Property（Termination_Date）），2011）&

（Restrictions.Eq（Employment_Status，Employmentstatus）））



.SetProjection（Projections.ProjectionList（）



.Add（Projections.Alias（Projections.Count（Projections.Property（Hire_Date）），WnType ））

.Add（Projections.Alias（Projections.Count（Projections.Property（Termination_Date）），WnameType）））





.SetResultTransformer（new NHibernate.Transform.AliasToBeanResultTransformer（typeof（LaunchPad）））;

返回FindAll（criteria1）.ToList（）;

i am doing like this but its not working ...here i am using this for display mvc graph


string employmentstatus = "Terminated";




DetachedCriteria criteria1 = DetachedCriteria.For<launchpad>()

.Add(Restrictions.Eq(Projections.SqlFunction("year", NHibernateUtil.Date, Projections.Property("Hire_Date")), 2013))
.Add(Restrictions.Eq(Projections.SqlFunction("year", NHibernateUtil.Date, Projections.Property("Termination_Date")), 2011) &
(Restrictions.Eq("Employment_Status", employmentstatus)))

.SetProjection(Projections.ProjectionList()

.Add(Projections.Alias(Projections.Count(Projections.Property("Hire_Date")), "WnType"))
.Add(Projections.Alias(Projections.Count(Projections.Property("Termination_Date")), "WnameType")))


.SetResultTransformer(new NHibernate.Transform.AliasToBeanResultTransformer(typeof(LaunchPad)));
return FindAll(criteria1).ToList();
