Hi,

I need a little help with creating an ICriteria query from a SQL
statement. I've got the following SQL statement correctly implemented
as an ICriteria.

SQL:
    select * from Index i inner join Order o on i.id = o.id where
o.Status = 4

NHibernate:
    IList<Index> papers = session
    .CreateCriteria(typeof(Index))
    .CreateAlias("Order", "Order")
    .Add(NHibernate.Criterion.Expression.Eq("Order.Status", 4))
    .List<Index>();


But how is it possible to add a subquery like this?

SQL:
select * from Index i inner join Order o on i.id = o.id where o.Status
= 4
AND (select count(*) from PPC where ppc.id = i.paperid) = 0

Thank you for taking the time to read my question :-)

Best regards
