thread-safe. This session factory is created in a static constructor C, and this constructor is executed the first time this helper class is accessed. The ISessionFactory is built from a Configuration D; this is the same process we ve demonstrated throughout the book. You catch and log exceptions E, but of course you should use your own logging mechanism rather than Console.Error. The utility class has one public method: a factory method for new ISessions F. It s a convenient method to shorten the code required for the most common usage of this class: opening new sessions. This (trivial) implementation stores the ISessionFactory in a static variable. Note that this design is completely cluster-safe. The ISessionFactory implementation is essentially stateless (it keeps no state relative to running transactions), except for the second-level cache. It s the responsibility of the cache provider to maintain cache consistency across a cluster. Thus you can safely have as many ISessionFactory instances as you like. Despite this freedom, in practice you want as few as possible, because the ISessionFactory consumes significant resources and is expensive to initialize. Now that we ve solved the problem of where to put the ISessionFactory instance (a common question that arises with NHibernate newcomers), we ll continue with the use-case implementation.

In this section, you ll write the code that implements the place bid use case in a single PlaceBidForItem() method, shown in listing 10.2. This code can live in an ASP.NET code-behind or a function in a console application. It doesn t matter; let s assume that wherever it is, the containing program will get some user input and pass it to this method. It s worth noting that this code sample isn t considered a good implementation, but we ll get to that shortly. It does give us a nice starting point for demonstrating the varying degrees of separation you can introduce into your applications.

public void PlaceBidForItem(long itemId, long userId, double bidAmount) { try { using(ISession session = NHibernateHelper.OpenSession()) using(session.BeginTransaction()) { Item item = session.Load<Item>(itemId, LockMode.Upgrade);

in the list of available values. Using Microsoft Visual Basic collection syntax, you can refer to a report parameter in any expression.

Change conditional formatting with a report parameter 1. Click the Layout tab, and then Click the Margin % cell, which is the cell in the sixth column of the detail row. 2. In the Properties window, click Expression in the Color property for the Margin % cell. 3. Position the cursor after the greater than symbol (<), and then delete 0.15 from the expression. 4. Click the Parameters collection to view its members. Each time you add a report parameter to the report, a new member is added to the Parameters collection for you to use in an expression. 5. Click MarginPercent, and then click Paste. The Edit Expression dialog box looks like this:

if ( item.EndDate < DateTime.Now ) { throw new BusinessException("Auction already ended."); IQuery q = session.CreateQuery(@"select max(b.Amount) from Bid b where b.Item = :item"); q.SetEntity("item", item); double maxBidAmount = (double) q.UniqueResult(); if (maxBidAmount > bidAmount) { throw new BusinessException("Bid too low."); User bidder = session.Load<User>(userId); Bid newBid = new Bid(bidAmount, item, bidder); item.AddBid(newBid);

session.Transaction.Commit(); } } catch (HibernateException ex) { throw new InfrastructureException( "Error while accessing the database", ex ); }

You first get a new ISession using your utility class B You then start a database transaction The session and transaction will be closed automatically due to the using() statement If you don t commit the transaction, or if this commit fails for some reason, the transaction will be automatically rolled back You load the Item from the database using its identifier value C and also ask for a pessimistic lock so the database won t allow another transaction to modify the record while you re working on it This prevents two simultaneous bids for the same item If the end date of the auction is earlier than the current date D, you throw an exception so that the persistence layer displays an error message Usually, you ll want more sophisticated error handling for this exception, with a qualified error message.
