How do you do an NHibernate inner join query? Should I use a subquery(DetachedCriteria), CreateCriteria or CreateAlias? Too many unhelpful examples when Googled. Here's the SQL:

select *
from contractdetails cd
inner join
contractheaders ch
on cd.contract_num = ch.contract_num
and cd.vendor_no = ch.vendor_no
and ch.chain_code = 'TA'
where
cd.item_no = '054064'
and cd.effective_price_date < '6/3/2010'
and cd.item_end_date > '6/3/2010'

I'm not going to get any StackOverflow points for answering this here Jimmy...

Fine, choose points over your buddies...

Got it:

#region Contracts
public ContractDetail ActiveContractDetail()
{
ContractDetail contractDetail = SessionManager.GetSession().CreateCriteria(typeof(ContractDetail))
.CreateAlias("ContractHeader", "h")
.Add(Expression.Eq("Item", this))
.Add(Expression.Eq("h.chain_code", "TA"))
.Add(Expression.Le("effective_price_date", DateTime.Today))
.Add(Expression.Ge("item_end_date", DateTime.Today))
.UniqueResult<ContractDetail>();

return contractDetail;
}
#endregion

I agree a good TA always has good food.
You're a very clever man Jimmy.

I as going to say CreateCriteria.
Really.
I swear.

But I dont know SQL

It's not really SQL, but you have to be able to write the query using T-SQL before transforming into an NHibernate query. The other part was creating a bag in the detail mapping file and a many-to-one relationship in the header mapping file or else the CreateAlias would not work.

ORMs are wonderful, they save writing a hundred lines of ADO code.

What is it? Delphi with SQL commands?

Where did you learn of this alien teaching

What is it? Delphi with SQL commands?

NHibernate is a port of Hibernate for the .Net platform. It's a popular Object Relational Mapping (ORM) technology. It allows you to refer to relational database tables as objects.

Funny you mention Delphi, I used Delphi in the 90's. It was better than Visual Basic until .Net came out.

Nice algorithm Phil except for the GoTo at the end. That's a no no.

Now, Jimmy, just save yourself some additional trouble and start using FluentNHibernate for configuration...

I don't know what all this means, so it must be for the devil, and evil.

now where did I put that damned pitchfork again?
