I

问题 I have the following query working which gets the results I want: int associatedId = 123; MyObject alias = null; var subQuery = QueryOver.Of<DatabaseView>() .Where(view => view.AssociatedId == associatedId) .And(view => view.ObjectId == alias.ObjectId) .Select(view => view.ObjectId); var results = session.QueryOver<MyObject>(() => alias) .WithSubquery.WhereExists(subQuery) .List(); DatabaseView has been mapped as an actual NHibernate entity (so I can use it with QueryOver), but it is not

问题 Is it possible to extend QueryOver API by somehow? What I want to add is the fol var criteria = QueryOver.Of<InternalAssessor>() .WhereRestrictionOn(x => x.Sector).HasAtLeastOneFlagSet((int)sector) Where sector is bit flag enum. We had such criterion for ICriteria API and I can do .Where(BitwiseRestrictions.AtLeastOneFlagSet("Sector", (int)sector)) But want to have strongly typed way of doing it. Are there any examples of extending QueryOver? 回答1: There is, pretty straightforward way, how to

问题 I have to write a query where for each vendor I have to read vendor's contact numbers from VendorContact but instead in rows, one row for each unique vendor and one columns for each phone number as comma separated string in main result. This can be done easily in plain SQL but I have to do it in QueryOver . I cannot declare variables in QueryOver SQL . var vendorvar = Session.QueryOver<Vendor>(() => V) .Left.JoinQueryOver(() => v.ContactNumbers, () => VendorContact) .SelectList(list => lst

问题 I have a simple database with users table, it have simple admin user with UserName= "Admin" Password="admin" I am using NHibernate to query over this table to login form. Suppose the login form inserted UserName="ADMIN" and password="ADMIN" both in upper case. The system should not allow login. However when I use the query like this using (var session = NhibernateHelper.OpenSession()) { return new List<User> (session.QueryOver<User>() .Where(u => u.UserName == userName) .And(u => u.Password =

问题 This is my current nhibenate query MappedHSPItemDto itemDtoAlias = null; TItem itemAlias = default(TItem); return Session.QueryOver<TMapItem>() .JoinAlias(x => x.Item, () => itemAlias, JoinType.InnerJoin) .Where(x => x.HealthServiceProvider == hsp) .SelectList(list => list .Select(x => x.Id).WithAlias(() => itemDtoAlias.Id) .Select(x => x.Version).WithAlias(() => itemDtoAlias.Version) .Select(x => x.HSPItemCode).WithAlias(() => itemDtoAlias.HSPItemCode) .Select(x => x.HSPItemName).WithAlias((

问题 This thing is keeping me busy for days and I hope someone of the NHibernate gurus can help me out. I've got a query set up which is working in SQL Server and I want to get the same in NHibernate. But all my tries (did a lot of googeling and browsing in stackoverflow) failed so far. Here's the query: Select j.id, j.title, j.company, jt.name as category, loc.city, je.is_assigned, FROM job j LEFT JOIN location loc ON loc.id = j.location LEFT JOIN job_tag jt ON jt.job = j.id and jt.name in

问题 I'm struggling to convert the following (simplified) HQL to QueryOver: select subscription from Subscription as subscription where not exists ( from Shipment as shipment where shipment.Subscription = subscription and (shipment.DeliveryDate = :deliveryDate) ) I've come this far: Subscription subscription = null; Session.QueryOver(() => subscription) .Where(Subqueries.NotExists(QueryOver.Of<Shipment>() .Where(shipment => shipment.Subscription == subscription) .And(shipment=> shipment

问题 Suppose the following Query using a NH 3.4 and RepositoryPattern var list = _repository .QueryOver() .Where(x => (x.Age > 20)) // notice the parantheses .Future() .ToList(); Whith these parantheses added the NH is failing to work, and causes a SO exception. If replacing .Where(x => (x.Age > 20)) with .Where(x => x.Age > 20) it works as expected. Any clues on why it doesn't work with extra parantheses? Note This is a simplified scenario from the bigger picture. In production i'm passing that
