queryover

could someone help me to translate LINQ expression to Nhibernate QueryOver from m in messages where !m.Recipients.Any(rcpt => rcpt.IsDeleted && rcpt.User = user) I tried this var qry = Session.QueryOver<UserMessage>(); qry.Where(m => m.Recipients.Any(r => !r.IsDeleted && r.User == user)); but got System.Exception : Unrecognised method call: System.Linq.Enumerable:Boolean Any[TSource](System.Collections.Generic.IEnumerable 1[TSource], System.Func 2[TSource,System.Boolean] !m.Recipients.Any(...) translates to a "not exists" sub-query. You will need a couple of aliases to correlate the sub-query

How can I perform the following LINQ to NHibernate query using the QueryOver API. This gets a list of all records of Item from the DB and places Items with the status "Returned" to the end of the list. The status is an Enum which is mapped to a nvarchar in the database. var workList = session.Query<Item>() .OrderBy(i=> i.Status == Status.Returned ? 1 : 0) .ToList(); The SQL equivalent is SELECT * FROM Item ORDER BY case when Status='Returned' then 1 else 0 end I've of course tried var workList = session.QueryOver<Item>() .OrderBy(i => i.Status == Status.Returned ? 1 : 0).Asc .ToList(); But I

I'm trying to write this specific sql query in nHibernate QueryOver language, which I am not very familiar with: SELECT MessageThreadId FROM MessageThreadAccesses WHERE ProfileId IN (arr) GROUP BY MessageThreadId HAVING COUNT(MessageThreadId) = arr.Count where arr is a array of integers(user Ids) I'm passing as argument and MessageThreadAccess entity looks like this: public virtual MessageThread MessageThread { get; set; } public virtual Profile Profile { get; set; } .... After reading multiple stack overflow threads and experimenting I got this far with my query (trying to get MessageThread

I'm trying to get a count from a query with a group by and just can't figure out how to translate the SQL I want into NHibernate's QueryOver syntax. This is the SQL: select count(*) from (select Email from Entry where (conditions...) group by Email) as tmp Seems simple right? This is how I'm trying to do it, but the RowCount() call seems to optimize the group by away completely: var query = _unitOfWork.CurrentSession.QueryOver<ContestEntry>() .Select(Projections.Property<ContestEntry>(x => x.Email), Projections.Group<ContestEntry>(x => x.Email)); return query.RowCount(); I wouldn't mind using

I´m trying to use QueryOver in that scenario : public class Class1 { public virtual string Name { get; set; } public virtual string Descripton { get; set; } public virtual Class2 { get; set; } public virtual IList<Class3> ListClass3{ get; set; } ... //SEVERAL OTHERS LISTS, PROPERTIES } public class Class2 { public virtual string Name { get; set; } ... //SEVERAL OTHERS LISTS, PROPERTIES } public class Class3 { public virtual string Name { get; set; } public virtual Class4 { get; set; } ... //SEVERAL OTHERS LISTS, PROPERTIES } public class Class4 { public virtual string Prop1 { get; set; }

I am trying some code out from a NH 3.0 Cookbook, and wondering why I can't get the code below to compile. I think the QueryProjectionBuilder that should make this work is in "NHibernate.Criterion.Lambda" but the using directive for it doesn't help. The problems are the SelectGroup and SelectAvg parts. Assuming the syntax from the book is correct, can anyone see a missing reference here? namespace Queries.Implementations { using System; using System.Collections.Generic; using System.Linq; using Eg.Core; using NHibernate; using NHibernate.Criterion; using NHibernate.Criterion.Lambda; public
