NHIbernate OR Criteria Query

Question

I have the following mapped classes

Trade { ID, AccountFrom, AccountTo }
Account {ID, Company}
Company {ID}

Now I cannot figure out a way s

Answer 1

Try:

return session.CreateCriteria()
    .CreateAlias("AccountFrom", "af")
    .CreateAlias("AccountTo", "at")
    .Add(Restrictions.Or(
        Restrictions.Eq("af.Company.CompanyId", companyId), 
        Restrictions.Eq("at.Company.CompanyId", companyId)))
    .List();

I don't think you will need to alias Company.
