Force query execution without flush/commit

Question

Hi i am using the transaction-per-request (session-in-view) pattern for an asp.net web application. I have a couple of points in the application where i want to Save an NHiberna

Have you tried using NHibernate's direct SQL features? Instead of breaking out into SQLCommand which NHibernate knows nothing about you can use ISession.CreateSQLQuery("native SQL here"). If you then do this inside a transaction after your Save method NHibernate should execute all the statements in order when the Commit happens. Thus:

using(var tx = session.BeginTransaction())
{
    try
    {
        FooClass fc = new FooClass("value");
        nhsession.Save(fc);

        var nativeQuery = nhsession.CreateSQLQuery("some insert/update query that depends on fc's id");

        // Add parameters to nativeQuery using SetXXX methods
        nativeQuery.SetXXX(...);

        // Save nativeQuery
        nativeQuery.Save(); // I think...

        tx.Commit();
    }
    catch (...)
    {
        tx.Rollback();
    }
}
