Fluent NHibernate - how to create table-per-subclass mapping using a discriminator?

问题 I've looked at a lot of questions on SO and google regarding sub-class mappings in nhibernate / fluent-nhibernate and not managed to find anyone with the same problem as me. I've followed the basic instructions from the fluent-nhibernate wiki (http://wiki.fluentnhibernate.org/Fluent_mapping#Subclasses) but this hasn't helped. I have a base entity called Operation - which has a base table associated with it, I then have sub-tables UnpaidCheque, Refund etc - the primary key for each of these

问题 I've been trying to map a clob field using Fluent NHibernate 1.2.0.712 against Oracle 10g. I'm using System.Data provider as it's available by default and was trying to avoid adding reference to ODP.Net due to previous client issues. However, when I try to insert entities with mapped clob properties, I get the error: ORA-01461: can bind a LONG value only for insert into a LONG column I've tried to fix this by using the below convention, and decorating the appropriate property with

问题 I have a class public class Account { public DateTime? StartDate {get;set;} public DateTime? EndDate {get;set;} public bool IsActive {get;set;} } the IsActive property is defined as a formula as .Formula(" StartDate < GETDATE() and (EndDate is NULL or EndDate > GetDate())") However when use QueryOver to query all Accounts where the IsActive == true I get an error that NHibernate cannot execute a SQL. The SQL that NHibernate generates has ...other criterias... and this_.StartDate < GETDATE()

NHibernate Save Is Trying to Clear Child KeyColumn Id On Update

问题 I am trying to create a parent object that has multiple children in a 1 to many relationship. I am not referencing the Parent object on the child object, instead I am mapping its keycolumn as a field. When I try to save this object for the first time, it works as expected without any issues (cascading all the Id's and children). When I try to get the object from the database, update some properties on it and re-save it again, it fails. The actual error message I am getting is "Could not

A role can be assigned to multiple users so I made my entity guts looks like: public class User { [Required] public virtual string FirstName { get; set; } public virtual Role Role { get; set; } } and role public class Role { [Required] public virtual string Name { get;

问题 Are there any good examples of how to use this (NHibernate.Criterion.IdentifierEqExpression) online? I couldn't find any. I'm a little confused about what you are supposed to pass into the constructor. I pass in an int32 of 1 and I keep thinking my test should basically do a "where id = 1" type of query and instead it blows up with "where id = ?" and something about positional parameters. If that's not what is supposed to be passed into the constructor ... what is? Real Issue When I look at
