My application creates a dynamically generated query at runtime based on user input by creating Criterion objects e.g: ICriterion criterion = Restrictions.Eq("Name", "John"); ...... detachedCriteriaSomewhereElse.Add(criterion); How do I do this in NHLambdaExtensions? what I really need to do is ICriterion criterion = Restrictions.Eq<Person>(p=> p.Name == "John"); but this isn't valid. Is there any way to do this? With the NHLambdaExtensions you have the SQLExpression class that lets you do the following: ICriterion criterion = SqlExpression.CriterionFor<Person>(p => p.Name == "John"); 来源：

I've got a Criteria Query for a social networking site. A Person object has a collection of Friends (also person objects). The query grabs the first N friends, but I also want to eager load an associated object MainProfileImage and then a subsequent associated object MediumThumbnail. I can do this in HQL easily: select friends from Person person inner join person.Friends friends inner join fetch friends.MainProfileImage image inner join fetch image.MediumThumbnail where person = :person1 order by friends.LatestLogin desc Here's My Criteria effort. For some reason this doesn't return anything!
