queryover

Is there a way to specify additional conditions on outer joins in NHibernate when querying using QueryOver or ICriteria? I need some extra conditions on the outer join-ed table, but NHibernate always adds them to the WHERE clause at the end - which does not get the correct behaviour (see http://weblogs.sqlteam.com/jeffs/archive/2007/05/14/criteria-on-outer-joined-tables.aspx ). I can't seem to find any way to do this using Criteria or the QueryOver syntax... Thanks You probably figure out this long time ago. Solution is to add ICriteria parameter in JoinAlias method, like this: Party

I'm in the process of learning QueryOver, but I can't for my life figure out how to do simple many to many queries. I've written the following: var result = Session.CreateCriteria(typeof (Product)) .CreateAlias("Categories", "categories") .Add(Property.ForName("categories.Id").Eq(categoryId)) .List<Product>(); This achieves the desired result. Basically I have Product > ProductCategory < Category ProductCategory just has ProductId / CategoryId, and I'm trying to select all the products in a specific category. I have no idea where to start with trying to do this with queryover. I ended up

I am using Nhibernate. I am writing query through queryover method. I am able to write and clause as in code below. Its working fine. db.QueryOver(Of Users)() .Where(Function(x) x.Role = "Guest") .And(Function(x) x.Block = 0) .And(Function(x) x.APPID = appId) .List(); But I want to use Or clause instead of And , or combination of both. How can I implement this. Thanks Radim Köhler Here is description how we can build OR with NHiberante NHibernate QueryOver with WhereRestriction as OR The syntax (in C# as the tag says) is: Restrictions.Or(restriction1, restriction1) Restrictions.Disjunction()

I have been searching for several hours now how to do this, but can't seem to find anything to help me. Here is the database model: This is the SQL query I am trying to run: SELECT b.*, a.Assignments FROM Branch b LEFT JOIN ( SELECT b.BranchID , COUNT(ab.BranchID) AS Assignments FROM Branch b LEFT JOIN AssignmentBranch ab ON b.BranchID = ab.BranchID GROUP BY b.BranchID ) a ON b.BranchID = a.BranchID So, basically, I want to return a list of branches and a new column that represents the number of assignments for that branch. Branch model public class Branch : IEntity<int> { public virtual int

I have an object model that looks like this (pseudo code): class Product { public ISet<Product> Recommendations {get; set;} public ISet<Product> Recommenders {get; set;} public ISet<Image> Images {get; set; } } When I load a given product and want to display the images of its recommendations, I run into an N+1 problem. (The recommendations are lazy-loaded, then a loop calls the .Images property of each one.) Product -> Recommendations -> Images What I want to do is eagerly load this particular part of the graph, but I can't figure out how to do it. I can load the recommendations eagerly, but

I want to use query over to give me back an object public class TaskMap : ClassMap<Task> { public TaskMap() { Table("Tasks"); Id(x => x.TaskId); Map(x => x.TaskName).NvarcharWithMaxSize().Not.Nullable(); Map(x => x.Description).NvarcharWithMaxSize(); Map(x => x.DueDate).Not.Nullable(); HasMany(x => x.PersonalTaskReminders).Inverse(); HasMany(x => x.TaskReminders).Inverse(); References(x => x.Course).Not.Nullable(); HasMany(x => x.CompletedTasks); } } [Serializable()] public class Task { public virtual int TaskId { get; private set; } public virtual string TaskName { get; set; } public virtual

I have a small problem with multiple instances of the same object after a join to an other table. For testing I create one Store with two Products (ManyToMany-Relation). The following snippet hopefully describes my problem. var preResult = _session.QueryOver<Store>().List(); // One store Product productAlias = null; var result = _session.QueryOver<Store>() .JoinAlias(s => s.Products, () => productAlias) .List(); // Two instances of the same store I even think this behavior is correct but how can I prevent the multiple instances? Is it possible within the query? Just for information why I need

I am using Asp net 5, NHibernate 3.3 and Kendo UI MVC wrapper for grid to render the table of client orders. There are lots of orders in database already and the number is constantly growing. So I decided to use server side paging to avoid fetching all orders from database. As far as I know you can't do paging manually and delegate filtering, sorting and grouping to ToDataSourceResult method. It's either all or nothing. Therefore I made an attempt to implement so called 'custom binding' . No problem until I get to grouping. I need to group first, then sort inside of a group, then extract data
