Question

I am using the following generic code to save entities.

using (ITransaction tx = session.BeginTransaction()) {     try     {        entity.DateModified = DateTime.Now;        session.SaveOrUpdate(entity);        session.Flush();        tx.Commit();        return entity;     }     catch (Exception)     {        tx.Rollback();        throw;     } } 

However, when I watch SQL Profiler I don’t see any BEGIN TRANSACTION being sent to SQL Server. Is this normal, expected?

Answer 1

I’ll suggest the obvious: make sure Profiler is set to display transaction information.

In the Trace Properties dialog -> Events selection tab, there’s an expando for Transactions. Open it up and check the appropriate boxes (or just check ’em all on).

Also, FYI: I checked our application that uses NHibernate, and yes I do see BEGIN TRANSACTION and COMMIT TRANSACTION calls while tracing in Profiler.
