问题 I'd like to have NHibernate call a stored procedure when ISession.Get is called to fetch an entity by its key instead of using dynamic SQL. We have been using NHibernate and allowing it to generate our SQL for queries and inserts/updates/deletes, but now may have to deploy our application to an environment that requires us to use stored procedures for all database access. We can use sql-insert, sql-update, and sql-delete in our .hbm.xml mapping files for inserts/updates/deletes. Our hql and

问题 Here's my NHibernate mapping. <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="HelloNHibernate" namespace="HelloNHibernate"> <class name="Showing" table="showing"> <id name="Id" column="showing_id"> <generator class="identity"/> </id> <many-to-one class="Theater" name="Theater" column="theater_id" foreign-key="fk_showing_theater_theater_id" cascade="delete" lazy="false" fetch="join"/> <many-to-one class="Movie" name="Movie" column="movie

问题 How can I get fluent nhibernate to create a varbinary field in a sql server 2005 table that uses a field size of varbinary(max)? At the moment I always get a default of varbinary(8000), which isn't big enough as i'm going to be storing image files. I've tried using CAstle.ActiveRecord but havent had any success yet. [ActiveRecord] public class MyFile : Entity { public virtual string FileName { get; set; } public virtual string FileType { get; set; } public virtual int FileVersion { get; set;

问题 In our NHibernate setup, we have a Listing entity. For DB performance reasons, we want to split the storage of it into multiple tables, by country (the way the site is set up, no-one can ever search in more than one country at a time). So, Listing_US, Listing_FR, etc. Two questions, the first far more important than the second: Is there any way NHibernate can do this mapping for me? Presumably it would be based around an internal field that gets generated on the Get() (where I'd pass in the

问题 I have 3 Entity USER, APPLICATION, and ROLE . I want there IDs to be joined in a table named USER_APP_ROLE(user_ID, application_ID, role_ID) with many to many relationship between them. Reason I want this structure is- I have requirement of allowing the user to work on multiple application with multiple roles. I have done the following codes: User.java @ManyToMany (targetEntity=Role.class) @JoinTable(name="USER_APPLICATION_ROLE", joinColumns=@JoinColumn(name="USER_ID"), inverseJoinColumns=

问题 I have problems with NHibernate updating some of my entities when this is not supposed to happen (dirty checking). As I use NHibernate.Mapping.Attributes to map my classes, I have found that there is a parameter "Check" to the element "Class" of NHMA. I would like to know if I can turn off dirty checking by setting this parameter to false or something (the required type for this parameter is string, so it may not be that). Any help would be appreciated ! 回答1: Firstly, this is not something
