the code above will give me the exception that the company dosen't
exist because it doesen't have been save yet, do I use two
transactions like the code under it will work because the the company
exists in db but not if Im only use one. What im out for is a solution
when I can have both savings in the same transaction and let
NHibernate figureout that the company will be saved when the
transaction is commited.
using(var transaction = session.BeginTransaction())
{
session.Save(company);
transaction.Commit();
}
using(var transaction = session.BeginTransaction())
{
session.Save(employe);
transaction.Commit();
}
