[nhibernate-issues] [NHJIRA] Commented: (NH-2317) Select after Take does not work properly

[Fabio M. (JIRA) <nh...@gm...>]

    [ http://216.121.112.228/browse/NH-2317?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=21156#action_21156 ] 

Fabio Maulo commented on NH-2317:
---------------------------------

As said above:
"The matter here is that even in RAM the Take before the Select and the Take after the Select has two completely different meaning and overall behavior."

The HQL equivalent of :
session.Query<Artist>().Take(3).Select(a => a.Id)

is:
select a.id from Artist a where a.id in (from Artist take 3)

and not
select a.id from Artist a take 3

> Select after Take does not work properly

> artists.Take(10).Select(a => a.Id) throws exception on 
> NHibernate.Hql.Ast.ANTLR.PolymorphicQuerySourceDetector.GetClassName(IASTNode querySource) en PolymorphicQuerySourceDetector.cs: line 62
> artists.Select(a => a.Id).Take(10) works properly
> These two queries work with the old provider.
