  • Parameter index is out of range

    - by czuroski
    Hello, I am getting the following error when trying to update an object using nhibernate. I am attempting to update a field which is a foreign key. Any thoughts why I might be getting this error? I can't figure it out from that error and my log4net log doesn't give any hints either. Thanks System.IndexOutOfRangeException was unhandled by user code Message="Parameter index is out of range."

  • NHibernate Proxy Creation

    - by Chris Meek
    I have a class structure like the following class Container { public virtual int Id { get; set; } public IList<Base> Bases { get; set; } } class Base { public virtual int Id { get; set; } public virtual string Name { get; set; } } class EnemyBase : Base { public virtual int EstimatedSize { get; set; } } class FriendlyBase : Base { public virtual int ActualSize { get; set; } } Now when I ask the session for a particular Container it normally gives me the concrete EnemyBase and FriendlyBase objects in the Bases collection. I can then (if I so choose) cast them to their concrete types and do something specific with them. However, sometime I get a proxy of the "Base" class which is not castable to the concrete types. The same method is used both times with the only exception being that in the case that I get proxies I have added some related entities to the session (think the friendly base having a collection of people or something like that). Is there any way I can prevent it from doing the proxy creating and why would it choose to do this in some scenarios? UPDATE The mappings are generated with the automap feature of fluentnhibernate but look something like this when exported <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-access="property" auto-import="true" default-cascade="none" default-lazy="true"> <class xmlns="urn:nhibernate-mapping-2.2" mutable="true" name="Base" table="`Base`"> <id name="Id" type="System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Id" /> <generator class="MyIdGenerator" /> </id> <property name="Name" type="String"> <column name="Name" /> </property> <joined-subclass name="EnemyBase"> <key> <column name="Id" /> </key> <property name="EstimatedSize" type="Int"> <column name="EstimatedSize" /> </property> </joined-subclass> <joined-subclass name="FriendlyBase"> <key> <column name="Id" /> </key> <property name="ActualSize" type="Int"> <column name="ActualSize" /> </property> </joined-subclass> </class> </hibernate-mapping> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-access="property" auto-import="true" default-cascade="none" default-lazy="true"> <class xmlns="urn:nhibernate-mapping-2.2" mutable="true" name="Container" table="`Container`"> <id name="Id" type="System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Id" /> <generator class="MyIdGenerator" /> </id> <bag cascade="all-delete-orphan" inverse="true" lazy="false" name="Bases" mutable="true"> <key> <column name="ContainerId" /> </key> <one-to-many class="Base" /> </bag> </class> </hibernate-mapping>

  • In NHibernate, how do I combine two DetachedCriteria instances

    - by Trevor
    My scenario is this: I have a base NHibernate query to run of the form (I've coded it using DetachedCriteria , but describe it here using SQL syntax): SELECT * FROM Items I INNER JOIN SubItems S on S.FK = I.Key The user interface to show the results of this join allows the user to specify additional criteria: Say: I.SomeField = 'UserValue'. Now, I need the final load command to be: SELECT * FROM Items I INNER JOIN SubItems S on S.FK = I.Key WHERE I.SomeField = 'UserValue' My problem is: I've created a DetachedCriteria with the 'static' aspect of the query (the top join) and the UI creates a DetachedCriteria with the 'dynamic' component of the query. I need to combine the two into a final query that I can execute on the NHibernate session. DefaultCriteria.Add() takes an ICriterion (which are created using the Expression class, and maybe other classes I don't know of which could be the solution to my problem). Does anyone know how I might do what I want?

  • How to implement paging in NHibernate with a left join query

    - by Gabe Moothart
    I have an NHibernate query that looks like this: var query = Session.CreateQuery(@" select o from Order o left join o.Products p where (o.CompanyId = :companyId) AND (p.Status = :processing) order by o.UpdatedOn desc") .SetParameter("companyId", companyId) .SetParameter("processing", Status.Processing) .SetResultTransformer(Transformers.DistinctRootEntity); var data = query.List<Order>(); I want to implement paging for this query, so I only return x rows instead of the entire result set. I know about SetMaxResults() and SetFirstResult(), but because of the left join and DistinctRootEntity, that could return less than x Orders. I tried "select distinct o" as well, but the sql that is generated for that (using the sqlserver 2008 dialect) seems to ignore the distinct for pages after the first one (I think this is the problem). What is the best way to accomplish this?

  • NHibernate's ISQLQuery returns instances that are of an unexpected type.

    - by Frederik Gheysels
    Hi all, I'm using NHibernate 2.1.2.400, and I'm having an issue with a an ISQLQuery query. The reason why I use an ISQLQuery here, is that this query uses a table for which I have no entity mapped in NHibernate. The query looks like this: ISQLQuery query = session.CreateSQLQuery ( "select p.*, price.* " + "from prestation p left outer join prestationprice price on p.PrestationId = price.PrestationId " + "where p.Id IN ( select id from prestationregistry where ..."); 'Prestationregistry' is the table that is not known by NHibernate (unmapped, so therefore the native SQL Query). my code continues like this: query.AddEntity ("p", typeof(Prestation)); query.AddJoin ("price", typeof(PrestationPrice)); query.SetResultTransformer (Transformers.DistinctRootEntity); var result = query.List(); So far so good. I expect that I'm given a list of 'Prestation' instances as a result of this query, since I declared 'Prestation' as being the root-object that has to be returned by the AddEntity method. I also expect that the PrestationPrices for each Prestation are eagerly loaded by this query (hence the AddJoin method). To my surprise, the List() method returns a collection of PrestationPrice instances instead of Prestation instances. How come ? Am I doing something wrong ? And if so, could you be so kind to tell me what I'm doing wrong ? Edit: Additional Info: When I debug, and put a watch on the 'query' instance, I can see that the queryReturns member of the query contains 2 items: - one NativeSqlQueryRootReturn instance who'se ReturnEntityName is 'Prestation' - one NativeSqlQueryJoinReturn When I do not specify the 'DistinctRootEntity' result transformer, the query returns instances of 'Prestation' instead of PrestationPrice. However, it contains multiple copies of the same instance.

  • NHibernate mapping with optimistic-lock="version" and dynamic-update="true" is generating invalid up

    - by SteveBering
    I have an entity "Group" with an assigned ID which is added to an aggregate in order to persist it. This causes an issue because NHibernate can't tell if it is new or existing. To remedy this issue, I changed the mapping to make the Group entity use optimistic locking on a sql timestamp version column. This caused a new issue. Group has a bag of sub objects. So when NHibernate flushes a new group to the database, it first creates the Group record in the Groups table, then inserts each of the sub objects, then does an update of the Group records to update the timestamp value. However, the sql that is generated to complete the update is invalid when the mapping is both dynamic-update="true" and optimistic-lock="version". Here is the mapping: <class xmlns="urn:nhibernate-mapping-2.2" dynamic-update="true" mutable="true" optimistic-lock="version" name="Group" table="Groups"> <id name="GroupNumber" type="System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="GroupNumber" length="5" /> <generator class="assigned" /> </id> <version generated="always" name="Timestamp" type="BinaryBlob" unsaved-value="null"> <column name="TS" not-null="false" sql-type="timestamp" /> </version> <property name="UID" update="false" type="System.Guid, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="GroupUID" unique="true" /> </property> <property name="Description" type="AnsiString"> <column name="GroupDescription" length="25" not-null="true" /> </property> <bag access="field.camelcase-underscore" cascade="all" inverse="true" lazy="true" name="Assignments" mutable="true" order-by="GroupAssignAssignment"> <key foreign-key="fk_Group_Assignments"> <column name="GroupNumber" /> </key> <one-to-many class="Assignment" /> </bag> <many-to-one class="Aggregate" name="Aggregate"> <column name="GroupParentID" not-null="true" /> </many-to-one> </class> </hibernate-mapping> When the mapping includes both the dynamic update and the optimistic lock, the sql generated is: UPDATE groups SET WHERE GroupNumber = 11111 AND TS=0x00000007877 This is obviously invalid as there are no SET statements. If I remove the dynamic update part, everything gets updated during this update statement instead. This makes the statement valid, but rather unnecessary. Has anyone seen this issue before? Am I missing something? Thanks, Steve

  • Nhibernate Criteria Query with Join

    - by John Peters
    I am looking to do the following using an NHibernate Criteria Query I have "Product"s which has 0 to Many "Media"s A product can be associated with 1 to Many ProductCategories These use a table in the middled to create the join ProductCategories Id Title ProductsProductCategories ProductCategoryId ProductId Products Id Title ProductMedias ProductId MediaId Medias Id MediaType I need to implement a criteria query to return All Products in a ProductCategory and the top 1 associated Media or no media if none exists. So although for example a "T Shirt" may have 10 Medias associated, my result should be something similar to this Product.Id Product.Title MediaId 1 T Shirt 21 2 Shoes Null 3 Hat 43 I have tried the following solutions using JoinType.LeftOuterJoin 1) productCriteria.SetResultTransformer(Transformers.DistinctRootEntity); This hasnt worked as the transform is done code side and as I have .SetFirstResult() and .SetMaxResults() for paging purposes it wont work. 2) .SetProjection( Projections.Distinct( Projections.ProjectionList() .Add(Projections.Alias(Projections.Property("Id"), "Id")) ... .SetResultTransformer(Transformers.AliasToBean()); This hasn't worked as I cannot seem to populate a value for Medias.Id in the projections. (Similar to http://stackoverflow.com/questions/1036116/nhibernate-criteria-api-projections) Any help would be greatly appreciated

  • How to debug nHibernate/RhinoMocks TypeInitializer exception

  • Translate query to NHibernate

    - by Rob Walker
    I am trying to learn NHibernate, and am having difficulty translating a SQL query into one using the criteria API. The data model has tables: Part (Id, Name, ...), Order (Id, PartId, Qty), Shipment (Id, PartId, Qty) For all the parts I want to find the total quantity ordered and the total quantity shipped. In SQL I have: select shipment.part_id, sum(shipment.quantity), sum(order.quantity) from shipment cross join order on order.part_id = shipment.part_id group by shipment.part_id Alternatively: select id, (select sum(quantity) from shipment where part_id = part.id), (select sum(quantity) from order where part_id = part.id) from part But the latter query takes over twice as long to execute. Any suggestions on how to create these queries in (fluent) NHibernate? I have all the tables mapped and loading/saving/etc the entities works fine.

  • Nhibernate equivalent of LinqToEntitiesDomainService in RIA

    - by VexXtreme
    Hi, When using Entity Framework with RIA domain services, domain services are inherited from LinqToEntitiesDomainService, which, I suppose, allows you to make linq queries on a low level (client-side) which propagate into ORM; meaning that all queries are performed on the database and only relevant results are retrieved to the server and thus the client. Example: var query = context.GetCustomersQuery().Where(x => x.Age > 50); Right now we have a domain service which inherits from DomainService, and retrieves data through NHibernate session as in: virtual public IQueryable<Customer> GetCustomers() { return sessionManager.Session.Linq<Customer>(); } The problem with this approach is that it's impossible to make specific queries without retrieving entire tables to the server (or client) and filtering them there. Is there a way to make linq querying work with NHibernate over RIA like it works with EF? If not, we're willing to switch to EF because of this, because performance impact would be just too severe. Thanks

  • NHibernate: Subqueries.Exists not working

    - by cbp
    I am trying to get sql like the following using NHibernate's criteria api: SELECT * FROM Foo WHERE EXISTS (SELECT 1 FROM Bar WHERE Bar.FooId = Foo.Id AND EXISTS (SELECT 1 FROM Baz WHERE Baz.BarId = Bar.Id) So basically, Foos have many Bars and Bars have many Bazes. I want to get all Foos that have Bars with Bazes. To do this, a detached criteria seems best, like this: var subquery = DetachedCriteria.For<Bar>("bar") .SetProjection(Projections.Property("bar.Id")) .Add(Restrictions.Eq("bar.FooId","foo.Id")) // I have also tried replacing "bar.FooId" with "bar.Foo.Id" .Add(Restrictions.IsNotEmpty("bar.Bazes")); return Session.CreateCriteria<Foo>("foo") .Add(Subqueries.Exists(subquery)) .List<Foo>(); However this throws the exception: System.ArgumentException: Could not find a matching criteria info provider to: bar.FooId = foo.Id and bar.Bazes is not empty Is this a bug with NHibernate? Is there a better way to do this?

  • NHibernate 2.1.2 in medium trust.

    - by John
    I'm trying to configure nhibernate 2.1.2 to run in medium trust, without any luck. I have tried follwing the suggestions to run in medium trust and pre-generating the proxies. I then tried to remove all references to lazy loading setting the default-lazy="false" on all classes and bags. However this threw an exception asking me to configure the proxyfactory.factory_class None of these methds worked as they kept throwing generic security exceptions or throwing easying that libraries do not allow AllowPartiallyTrustedCallers. Am I using the wrong version of NHibernate if I want to run in medium trust? Is there a specific set of binaries, or source, which I should be using.

  • Nhibernate one-to-many with table per subclass

    I am customizing N2CMS's database structure, and met with an issue. The two classes are listed below. public class Customer : ContentItem { public IList<License> Licenses { get; set; } } public class License : ContentItem { public Customer Customer { get; set; } } The nhibernate mapping are as follows. <class name="N2.ContentItem,N2" table="n2item"> <cache usage="read-write" /> <id name="ID" column="ID" type="Int32" unsaved-value="0" access="property"> <generator class="native" /> </id> <discriminator column="Type" type="String" /> </class> <subclass name="My.Customer,My" extends="N2.ContentItem,N2" discriminator-value="Customer"> <join table="Customer"> <key column="ItemID" /> <bag name="Licenses" generic="true" inverse="true"> <key column="CustomerID" /> <one-to-many class="My.License,My"/> </bag> </join> </subclass> <subclass name="My.License,My" extends="N2.ContentItem,N2" discriminator-value="License"> <join table="License" fetch="select"> <key column="ItemID" /> <many-to-one name="Customer" column="CustomerID" class="My.Customer,My" not-null="false" /> </join> </subclass> Then, when get an instance of Customer, the customer.Licenses is always empty, but actually there are licenses in the database for the customer. When I check the nhibernate log file, I find that the SQL query is like: SELECT licenses0_.CustomerID as CustomerID1_, licenses0_.ID as ID1_, licenses0_.ID as ID2_0_, licenses0_1_.CustomerID as CustomerID7_0_, FROM n2item licenses0_ inner join License licenses0_1_ on licenses0_.ID = licenses0_1_.ItemID WHERE licenses0_.CustomerID = 12 /* @p0 */ It seems that nhibernate believes that the CustomerID is in the 'n2item' table. I don't know why, but to make it work, I think the SQL should be something like this. SELECT licenses0_.ID as ID1_, licenses0_.ID as ID2_0_, licenses0_1_.CustomerID as CustomerID7_0_, FROM n2item licenses0_ inner join License licenses0_1_ on licenses0_.ID = licenses0_1_.ItemID WHERE licenses0_1_.CustomerID = 12 /* @p0 */ Could any one point out what's wrong with my mappings? And how can I get the correct licenses of one customer? Thanks in advance.

  • Add objects to association in OnPreInsert, OnPreUpdate

    - by Dmitriy Nagirnyak
    Hi, I have an event listener (for Audit Logs) which needs to append audit log entries to the association of the object: public Company : IAuditable { // Other stuff removed for bravety IAuditLog IAuditable.CreateEntry() { var entry = new CompanyAudit(); this.auditLogs.Add(entry); return entry; } public virtual IEnumerable<CompanyAudit> AuditLogs { get { return this.auditLogs } } } The AuditLogs collection is mapped with cascading: public class CompanyMap : ClassMap<Company> { public CompanyMap() { // Id and others removed fro bravety HasMany(x => x.AuditLogs).AsSet() .LazyLoad() .Access.ReadOnlyPropertyThroughCamelCaseField() .Cascade.All(); } } And the listener just asks the auditable object to create log entries so it can update them: internal class AuditEventListener : IPreInsertEventListener, IPreUpdateEventListener { public bool OnPreUpdate(PreUpdateEvent ev) { var audit = ev.Entity as IAuditable; if (audit == null) return false; Log(audit); return false; } public bool OnPreInsert(PreInsertEvent ev) { var audit = ev.Entity as IAuditable; if (audit == null) return false; Log(audit); return false; } private static void LogProperty(IAuditable auditable) { var entry = auditable.CreateAuditEntry(); entry.CreatedAt = DateTime.Now; entry.Who = GetCurrentUser(); // Might potentially execute a query. // Also other information is set for entry here } } The problem with it though is that it throws TransientObjectException when commiting the transaction: NHibernate.TransientObjectException : object references an unsaved transient instance - save the transient instance before flushing. Type: CompanyAudit, Entity: CompanyAudit at NHibernate.Engine.ForeignKeys.GetEntityIdentifierIfNotUnsaved(String entityName, Object entity, ISessionImplementor session) at NHibernate.Type.EntityType.GetIdentifier(Object value, ISessionImplementor session) at NHibernate.Type.ManyToOneType.NullSafeSet(IDbCommand st, Object value, Int32 index, Boolean[] settable, ISessionImplementor session) at NHibernate.Persister.Collection.AbstractCollectionPersister.WriteElement(IDbCommand st, Object elt, Int32 i, ISessionImplementor session) at NHibernate.Persister.Collection.AbstractCollectionPersister.PerformInsert(Object ownerId, IPersistentCollection collection, IExpectation expectation, Object entry, Int32 index, Boolean useBatch, Boolean callable, ISessionImplementor session) at NHibernate.Persister.Collection.AbstractCollectionPersister.Recreate(IPersistentCollection collection, Object id, ISessionImplementor session) at NHibernate.Action.CollectionRecreateAction.Execute() at NHibernate.Engine.ActionQueue.Execute(IExecutable executable) at NHibernate.Engine.ActionQueue.ExecuteActions(IList list) at NHibernate.Engine.ActionQueue.ExecuteActions() at NHibernate.Event.Default.AbstractFlushingEventListener.PerformExecutions(IEventSource session) at NHibernate.Event.Default.DefaultFlushEventListener.OnFlush(FlushEvent event) at NHibernate.Impl.SessionImpl.Flush() at NHibernate.Transaction.AdoTransaction.Commit() As the cascading is set to All I expected NH to handle this. I also tried to modify the collection using state but pretty much the same happens. So the question is what is the last chance to modify object's associations before it gets saved? Thanks, Dmitriy.

  • NHibernate CreateSQLQuery data conversion from bit to boolean error

    - by RemotecUk
    Hi, Im being a bit lazy in NHibernate and using Session.CreateSqlQuery(...) instead of doing the whole thing with Lambda's. Anyway what struct me is that there seems to be a problem converting some of the types returned from (in this case the MySQL) DB into native .Net tyes. The query in question looks like this.... IList<Client> allocatableClients = Session.CreateSQLQuery( "select clients.id as Id, clients.name as Name, clients.customercode as CustomerCode, clients.superclient as SuperClient, clients.clienttypeid as ClientType " + ... ... .SetResultTransformer(new NHibernate.Transform.AliasToBeanResultTransformer(typeof(Client))).List<Client>(); The type in the database of SuperClient is a bit(1) and in the Client object the type is a bool. The error received is: System.ArgumentException: Object of type 'System.UInt64' cannot be converted to type 'System.Boolean'. It seems strange that this conversion cannot be completed. Would be greatful for any ideas. Thanks.

  • NHibernate IPreUpdateEventListener weird behaviour

    - by mcaaltuntas
    I am using NHibernate 2.0.1 and IPreUpdateEventListener,IPreInsertEventListener events for audit logging purposes. I have a basic entity that has a one to many relation like this. User-------Books From an ASP.NET MVC controller method i am adding a book to a user like this. Book book =new Book("LOTR"); var userBook=user.AddBook(book); After session flushing OnPreInsert event called once for newly created Book object than OnPreUpdate called for all books objects in user's books collection even they have not changed.So I am updating LastMofiedDate property of all books objects and I dont want to do this. Is this supposed behaviour of NHibernate or am I missing something?

  • Scalar-Valued Function in NHibernate

    - by Byron Sommardahl
    I have the following scalar function in MS SQL 2005: CREATE FUNCTION [dbo].[Distance] ( @lat1 float, @long1 float,@lat2 float, @long2 float ) RETURNS float AS BEGIN RETURN (3958*3.1415926*sqrt((@lat2-@lat1)*(@lat2-@lat1) + cos(@lat2/57.29578)*cos(@lat1/57.29578)*(@long2-@long1)*(@long2-@long1))/180); END I need to be able to call this function from my NHibernate queries. I read over this article, but I got bogged down in some details that I didn't understand right away. If you've used scalar functions with NHibernate, could you possibly give me an example of how your HBM file would look for a function like this?

  • please explain NHibernate HiLo

    - by Ben
    I'm struggling to get my head round how the HiLo generator works in NHibernate. I've read the explanation here which made things a little clearer. My understanding is that each SessionFactory retrieves the high value from the database. This improves performance because we have access to IDs without hitting the database. The explanation from the above link also states: For instance, supposing you have a "high" sequence with a current value of 35, and the "low" number is in the range 0-1023. Then the client can increment the sequence to 36 (for other clients to be able to generate keys while it's using 35) and know that keys 35/0, 35/1, 35/2, 35/3... 35/1023 are all available. How does this work in a web application as don't I only have one SessionFactory and therefore one hi value. Does this mean that in a disconnected application you can end up with duplicate (low) ids in your entity table? In my tests I used these settings: <id name="Id" unsaved-value="0"> <generator class="hilo"/> </id> I ran a test to save 100 objects. The IDs in my table went from 32768 - 32868. The next hi value was incremented to 2. Then I ran my test again and the Ids were in the range 65536 - 65636. First off, why start at 32768 and not 1, and secondly why the jump from 32868 to 65536? Now I know that my surrogate keys shouldn't have any meaning but we do use them in our application. Why can't I just have them increment nicely like a SQL Server identity field would. Finally can someone give me an explanation of how the max_lo parameter works? Is this the maximum number of low values (entity ids in my head) that can be created against the high value? This is one topic in NHibernate that I have struggled to find documentation for. I read the entire NHibernate in action book and it still doesn't go into how this works in any detail. Thanks Ben

  • Relying on nhibernate's second level cache vs pushing objects into the session

    - by AhmetC
    I have some big entities which are frequently accessed in the same session. For example, in my application there is a reporting page which consist of dynamically generated chart images. For each chart image on this page, the client makes requests to corresponding controller and the controller generates images using some entities. I can either use asp.net's session dictionary for "caching" those entities or rely on nhibernate's second level cache support with using cached queries for example. What is your opinion? By the way I will use shared hosting, is nhibernate's second level cache hosting friendly? Thanks.
