I don't think so?! I could be wrong though.
Futures in a way that you can write couple of seperate queries, mark
them as future and have the engine execute them all with something
like multiplecriteria in one batch when you call the result of the
first one?

you are using an old version of NH or you have disabled the autoimport of

You can inherit from the dialect and add the keyword TOP.

For sure what you are defining 'bug' is not the order you are seeing

The new parser may have some problem when the alias has the same name of a

I think you are right.IQueryable (LINQ) is about single query yet to be
executed, while Future is about multiple (probably independent) queries.
In NH 3.0, there are two new query APIs, the LINQ one, and the IQueryOver
one, which is sort of similar to criteria (I think), but is strongly

I think the trend is not to extend IQueryable much (unlike the older LINQ
provider that had the Expand() function), and to invest in IQueryOver
instead.
I cannot confirm whether this is really the case though as all I do is I
read the public APIs after building NH from newer revision.Personally,

Probably we will include some persistence-oriented extensions to our

btw have a look to QueryOver if you want find Linq-like syntax and all

A disadvantage of the queryover api is that it does not support all
functions in the linq api. That makes it useful to extend the linq api.

The use of the new keyword is usually an indicator of bad design (you have
two elements in the same hierarchy, with the same name but different
meanings). Plus, you are trying to add additional constraints on

Ups if so a generic class would be better
BaseClassT
public virtual IColllectionT Collection { get;set; }
ChildClass: BaseClassChildClassCollection
then you can map the collection to internal field and use Linq OfTypeT to
return the expected strongly-typed enumerable.

explain what you do with the criteria. If I'm right with HQL I can do
