NHibernate - Is there a way to map a formula that uses sql function and returns Table?!

I have a sql function that returns table and I need to map it to a collection i'm trying with formula but as far as i can tell formula is good only to single returned value (right?!?)

is there a way to use formula and map it to a DataTable or some other collection

<propery name="Prop" type="DataTable" for开发者_StackOverflow社区mula="select function(...)"/>

if not what are my other options?!

thanks!

For return value you can use DTO or Persistence class
