Hi,
I need to serialise a data tree however the performance of this is
understandable poor as all children must be fetched prior to
serialisation. I was looking for a better performing way of doing
this.
Currently before serialising a child collection I check wether the
collection is empty by:
if(NHibernate.NHibernateUtil.IsInitialized(Children)) { return
Children.Count() > 0; }
NHibernate.IQuery q = GetSession().CreateFilter(Children, "Select
count(*)");
return Convert.ToInt32(q.UniqueResult()) > 0;
This greatly improves performance over a straight call to
Children.Count() but I still think there must be a better way of doing
this.
If an Entity has 2+ children collections can I get their count in one
database call?
Any other suggestions?
Thanks
Guido Tapia
