I have simple HQL query:
var list = OpenSession()
.CreateQuery("SELECT MAX(p.price) as max_price,
COUNT(p.id) as count_all
FROM Order o left join o.Products p")
.List();
I would like to output "max_price" and "count_all" columns/projections as easy as possible.
Something like:
Console.WriteLine(list[0]["max_price"]);
Console.WriteLine(list[0]["count_all]);
Any idea?
您可以将其转换为Hashtable
.SetResultTransformer(Transformers.AliasToEntityMap).List<HashTable>()[0]["max_price"];
Not sure about this but I think that you will need to create a class and project into that. This is how I would start by approaching it
class UserStatistics{
MaxPrice {get; set;}
CountAll {get; set;}
}
var list = OpenSession()
.CreateQuery("SELECT MAX(p.price) as max_price,
COUNT(p.id) as count_all
FROM Order o left join o.Products p")
.SetResultTransformer(NHibernate.Transform.Transformers.AliasToBean(typeof(UserStatistics)))
.List<UserStatistics>();
then it should be a matter of
Console.WriteLine(list[0].MaxPrice);
Console.WriteLine(list[0].CountAll);
