"because you don't control the table alias" Sorry. are there any way to get the name of the object on sql? Nhibernates generates something like this: "From Object1 this_ inner join Object2 this_1 on this_.Id=this1.Id inner join......" If i get, for example, "this_1" from this SQL and put on my SQL String it can work i think.
