將SQL查詢轉換為Nhibernate條件

Question

我的SQL查詢：

select [CompanyId] 
from dbo.Bussiness_Company
where [BussinessId] in (11,12,13)
group by [CompanyId]
having COUNT(distinct [BussinessId])=3

說明：我有一張Bussiness_Company表：

業務_公司

ID*

BussinessId

公司編號

我的資料：

ID ---------業務ID ------------公司ID

1 ---------- 10 --------------------- 100

2 ---------- 11 --------------------- 100

3 ---------- 12 --------------------- 100

重新查詢

公司編號

100

這是我的代碼：

DetachedCriteria detachedCriteria = DetachedCriteria.For<BussinessCompany>();
 detachedCriteria.SetProjection(Projections.Property("Company"));
 detachedCriteria.SetProjection(Projections.GroupProperty("Company"));
 Disjunction disjunction = Restrictions.Disjunction();
 foreach (Bussiness bussiness in list)
 {
   disjunction.Add(Restrictions.Eq("Bussiness", bussiness ));
 }                  detachedCriteria.Add(disjunction).Add(Restrictions.Eq(Projections.CountDistinct<BussinessCompany>(m => m.Bussiness), list.Count));

 IList<Sonomi.Core.BusinessObjects.Bussiness> bussiness =
                    bussinessUnitManager.CreateCriteria().Add(Subqueries.PropertyIn("Id", detachedCriteria)).List
 <Sonomi.Core.BusinessObjects.BussinessUnit>();

 dgrCer.DataSource = bussiness;
 dgrCer.DataBind();

您可以嘗試這樣的QueryOver代碼：

var bussinessIdCount = 3;
var bussinessIds = new[] { 11, 12, 13 };
Bussiness_Company bussinessCompany = null;
session.QueryOver(() => bussinessCompany)
  .WhereRestrictionOn(() => bussinessCompany.BussinessId).IsIn(bussinessIds)
  .Select(Projections.Group(Projections.Property(() => bussinessCompany.CompanyId)))
  .Where(Restrictions.Gt(Projections.CountDistinct(() => bussinessCompany.BussinessId), bussinessIdCount));
