將my-sql查詢轉換爲nhibernate查詢

有人可以幫我或讓我開始將此查詢轉換爲nhibernate查詢轉換查詢嗎？將my-sql查詢轉換爲nhibernate查詢

SELECT 
    Campaign.Id, 
    Location.Name, 
    Location.PrimaryPostcode, 
    Inventory.Section, 
    Campaign.Sov, 
    IFNULL(Contracts.Spend, 0) AS Spend, 
    IFNULL(Contracts.Impressions, 0) AS Impressions, 
    IFNULL(Days, 0) Days, 
    RenewalDate, 
    LastContract.OptIn 
FROM 
    Contract AS Campaign 
    JOIN Inventory ON Campaign.InventoryId = Inventory.Id 
    JOIN Location ON Inventory.LocationId = Location.Id 
    LEFT OUTER JOIN (
     SELECT 
      CampaignId, 
      SUM(RackRate) AS Spend, 
      SUM(Impressions) AS Impressions, 
      1 + DATEDIFF(Now(), MIN(StartDate)) AS Days, 
      DATE_SUB(MAX(EndDate), INTERVAL 11 Day) AS RenewalDate, 
      MAX(StartDate) AS CurrentOrNextStartDate 
     FROM 
      Contract 
      LEFT OUTER JOIN Creative On Creative.ContractId = Contract.Id 
      LEFT OUTER JOIN CreativeLog On Creative.Id = CreativeLog.CreativeId    
     GROUP BY 
      CampaignId 
    ) AS Contracts ON Campaign.Id = Contracts.CampaignId 
    LEFT OUTER JOIN (
     SELECT 
      CampaignId, 
      Id, 
      Optin, 
      StartDate 
     FROM 
      Contract 
    ) AS LastContract ON Campaign.Id = LastContract.CampaignId AND Contracts.CurrentOrNextStartDate = LastContract.StartDate 
WHERE 
    Campaign.AgencyId = '04ba6b28-a7a0-4448-b21f-9f2b00a4621b' 
ORDER BY 
    RenewalDate, 
    Location.Name, 
    Inventory.Section

我沒有做它過去在這裏：

_session.QueryOver<Contract>() 
    .Left.JoinQueryOver<Contract>(campaign => campaign.Contracts).List()

即因爲NHibernate的是對條款有兩種表的別名標識==編號之間產生時，它應該是CAMPAIGNID ==標識。

FROM Contract this_ left outer join Contract contract1_ on this_.Id=contract1_.Id

合同的「合同」屬性是自引用關係。這不是1：1。

我已經非常認爲這不能在查詢中完成。至少不是以最佳方式。無法加入投影，然後從中選擇幾乎是一個表演塞。

你需要展示或解釋你的映射是如何完成的。如果你打算將Contract加入自己，那麼你需要告訴它要加入什麼，否則它會在主鍵上執行。如果你在最新的nhibernate，我相信你可以做一個.With，並告訴它加入到不同的列。如果它沒有那裏，但你可以做到這一點.UnderlyingCriteria
