The Problem: All tables in our database have CreatedDate, CreatedBy, ChangedDate, ChangedBy fields which I want to be set automatically when Saving / Updating an ActiveRecord entity. My first try was to override the Save() and Update() methods. But these methods only get called when I do a direct Save() or Update() on the entity. They are not being called in a Master - Detail scenario where I call Save() only on the master. Next try were the OnSave() and OnUpdate() methods, but here changes in the fields were not persisted in the database. Finally I tried the BeforeSave() method. But this

I have implemented a search function using Castel Active Record. I thought the code is simple enough but I kept getting NHibernate.QueryParameterException : could not locate named parameter [searchKeyWords] errors. Can someone tell me what went wrong? Thanks a million. public List<Seller> GetSellersWithEmail(string searchKeyWords) { if (string.IsNullOrEmpty(searchKeyWords)) { return new List<Seller>(); } string hql = @"select distinct s from Seller s where s.Deleted = false and ( s.Email like '%:searchKeyWords%')"; SimpleQuery<Seller> q = new SimpleQuery<Seller>(hql); q.SetParameter(

I have integrated NHibernate.Search into my web app by following tutorials from the following sources: NHibernate.Search using Lucene.NET Full Text Index (Part 1) Using NHibernate.Search with ActiveRecord I have also successfully batch-indexed my database, and when testing against Luke, I can search for terms that reside in whatever entities I marked as indexable. However , when I attempt to update many-to-many entities via my web app, my parent index does not seem to update. For example: public class Books { HasAndBelongsToMany(typeof(Author), Table = "BookAuthor", ColumnKey = "BookId",

I'm having a difficult time finding information on how to elegantly serialize ActiveRecord objects. We would like to use XML as the format because we need to output our objects in such a way that another program will be able to feasibly parse them. XML-Serialization is usually very easy and straightforward to implement, but the problem comes when trying to serialize an object returned from the ActiveRecord database. The database returns a proxy class of the object, the type of which cannot be explicitly anticipated via the [XmlInclude] attribute. For example: public class Foo :

How do you pass a list of things for the 'in' clause in Nhibernate HQL? e.g. // data input from the user interface, not known at compile time object[] productIds = {1, 17, 36, ... }; string hqlQuery = @" from Product as prod where prod.Id in ( ? )"; HqlBasedQuery query = new HqlBasedQuery(typeof(Product), hqlQuery, productIds) ActiveRecordMediator.ExecuteQuery(query); Now, this isn't going to work, as much as I wish it would! Am I really stuck doing something like this: // data input from the user interface, not known at compile time object[] productIds = {1, 17, 36, ... }; string hqlQuery = @

I am using NHibernate to connect to a legacy rdbms system. Under high production load the rdbms service fails. To maintain the availability we have a failover rdbms service. Is there a way to configure NHibernate to use the FailOver Connection String when the primary connection is down? Additional Info: I am using Castle over NHibernate. If Castle provides handling of failover connections then that will also do it for me. You can build your own NHibernate.Connection.IConnectionProvider which provides failover support. This should be a subclass of ConnectionProvider which overrides

Has anybody tried mapping database views in oracle using ActiveRecord? Please can I get some sample code for that? No code necessary: just use the view name instead of the table in your [ActiveRecord] attribute: [ActiveRecord("MyView")] public class Document {...} Be aware that SchemaExport will treat your view as a table, here's how to fix that. 来源： https://stackoverflow.com/questions/2048483/how-to-map-a-database-view-using-activerecord
