Nhibernate Queryover Case Insensitive IsIn

Question

I've got this example code...

Result = session.QueryOver<Lfee_Exc>().WhereRestrictionOn(x => x.FirstName)
.IsIn(ListOfFirstNames).List();

Is there any way to make this case insenstive or upper case x.ArNumber for my case sensitive Oracle server?

Answer 1

Convert ListOfFirstNames to upercase and then:

session.QueryOver<Lfee_Exc>()
    .Where(Restrictions.In(Projections.SqlFunction(
                              "upper", NHibernateUtil.String,
                               Projections.Property<Lfee_Exc>(x => x.FirstName)),
                           ListOfFirstNames))
