我正在尝试创建一个映射,以便从下面的查询中获取结果。 我很难得到设置的产品映射,以在3列上设置对Product_Line的引用,就像在哪里条件一样。我如何使用流利来实现这一点?流利的nhibernate映射
产品表:CID,PROJID,线路等,列 Product_Line表:CID,PROJID,线路等,列
,选择F *从乘积F 加入上f.cId Product_Line诉= v.CId和f.ProjID = v.ProjID and f.line = v.line
在此先感谢。 RajeshC
首先,非常感谢您寻找到它,并在这里与更多的信息: //所需物品:我想查询产品,例如,如果没有PRODUCTLINE,然后我想创建一个PRODUCTLINE,如果有一个,那么我会更新它。
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") //
}
我更新了代码示例。提前致谢。 – rajeshC 2010-09-02 15:45:24
如何使用HasOne这样? (m => m.Line).ForeignKey(“CustId”)。ForeignKey(“PROJId”)。ForeignKey(“LINENUMBER”); – rajeshC 2010-09-02 16:09:09
