Fabio Maulo commented on NH-2736:
---------------------------------

Ok Andrei thanks for the issue.
The skip/take with parameter are already suffering some bugs due to the no-meaning Parameter way NH manage parameters all around the code.
Patrick are working in another big refactoring to cut the problem at its root.
I'll find a workaround just for this release.

> Hello,
> When I create a HQL query using parameters the parameters are inverted.
> Here is an example (I'll attach a test as soon as I have the issue number):
> 				var query = session.CreateQuery("select o.Id, i.Id from SalesOrder o left join o.Items i with i.Quantity = :p0 take :p1");
> 				query.SetParameter("p0", 1);
> 				query.SetParameter("p1", 2);
> 				var result = query.List();
> 				Assert.That(result.Count, Is.EqualTo(2));
> The SQL Statement is:
> exec sp_executesql N'select TOP (@p0)  salesorder0_.Id as col_0_0_, items1_.Id as col_1_0_ from SalesOrder salesorder0_ left outer join Item items1_ on salesorder0_.Id=items1_.SalesOrder and (items1_.Quantity=@p1)',N'@p0 int,@p1 int',@p0=1,@p1=2
> So the query selects the top 1 rows and the quantity column is filtered with 2.
> Probably this bug is related with the implementation that allows to specify the take rows using parameters.
> Thanks,
> Andrei
