总在order = (COrder)session.Load(typeof(COrder),1)这行，提示
NHibernate.ADOException: could not initialize collection: [EnPrint.DB.COrder.Items#1] ---> System.Data.OleDb.OleDbException: 至少一个参数没有被指定值。
的错误信息。检查其Sql语句，明显不是我所期待的
NHibernate :SELECT corder0_.ID as ID0_, corder0_.Customer_ID as Customer2_0_, corder0_.BuildDate as BuildDate0_ FROM [Order] corder0_ WHERE corder0_.ID=?
NHibernate :SELECT items0_.ID as ID__, items0_.OrderItem_ID as OrderIte1___, items0_.OrderItem_ID as OrderIte1_1_, items0_.Price as Price1_, items0_.Quantity as Quantity1_, items0_.Product_ID as Product_ID1_, items0_.Order_ID as Order_ID1_, corder1_.ID as ID0_, corder1_.Customer_ID as Customer2_0_, corder1_.BuildDate as BuildDate0_ FROM OrderItem items0_ left outer join [Order] corder1_ on items0_.Order_ID=corder1_.ID WHERE items0_.ID=?
第二行语句的Where语句总应是“where item0_.Order_ID=?”吧?NHibernate :SELECT items0_.ID as ID__, items0_.OrderItem_ID as OrderIte1___, items0_.OrderItem_ID as OrderIte1_1_, items0_.Price as Price1_, items0_.Quantity as Quantity1_, items0_.Product_ID as Product_ID1_, items0_.Order_ID as Order_ID1_, corder1_.ID as ID0_, corder1_.Customer_ID as Customer2_0_, corder1_.BuildDate as BuildDate0_ FROM OrderItem items0_ left outer join [Order] corder1_ on items0_.Order_ID=corder1_.ID WHERE items0_.ID=?
我使用过1.0和1.0.1的版本都是如此。纳闷中....
