流利的nhibernate映射

Question

我正在嘗試創建一個映射，以便從下面的查詢中獲取結果。 我很難得到設置的產品映射，以在3列上設置對Product_Line的引用，就像在哪裏條件一樣。我如何使用流利來實現這一點？

產品表：CID，PROJID，線路等，列 Product_Line表：CID，PROJID，線路等，列

，選擇F *從乘積F 加入上f.cId Product_Line訴= v.CId和f.ProjID = v.ProjID and f.line = v.line

在此先感謝。 RajeshC

首先，非常感謝您尋找到它，並在這裏與更多的信息： //所需物品：我想查詢產品，例如，如果沒有PRODUCTLINE，然後我想創建一個PRODUCTLINE，如果有一個，那麼我會更新它。

public class ProductMap : ClassMap<Product> 
{ 
    Id(x => x.Id); 
    Map(x => x.CustomerId, "CustId"); 
    Map(x => x.ProjId, "PROJId"); 
    Map(x => x.LineNumber, "LineNumber"); 
    Map(x => x.ReportType, "ReportType"); 
// Reference to Product_Line? - this reference should be based on three columns (custId, ProjId, LineNumber) 
    References(x => x.Line); 
} 

public class ProductLineMap : ClassMap<ProductLine> 
{ 
    Table("Product_Line"); 
    Map(x => x.CustomerId, "CustId"); //same column as Product.CustId 
    Map(x => x.ProjId, "PROJId"); //Same as Product.ProjId 
    Map(x => x.LineNumber, "LINENUMBER"); //Same as Product.LineNumber 
    //etc., 
    //for me, this reference is not needed as I need from Product to ProductLine - one way. 
    //References(x => x.Product).Column("ProjId") // 
}

我們可以給你一個更好的答案，如果你向我們展示你的C＃代碼，幷包裹在SQL中< code>標記......這是我的猜測是我認爲你想：

public class ProductMap : ClassMap<Product> 
{ 
    Id(x => x.Id); 
    References(x => x.Line); // Reference to Product_Line? 
    // etc. 
} 

public class ProductLineMap : ClassMap<ProductLine> 
{ 
    Table("Product_Line"); 
    Id(x => x.Id).Column("cId"); 
    References(x => x.Product).Column("ProjId") 
}
