   1:publicstatic String ToSql(this IQueryable queryable)

   2: {

   3:     var sessionProperty = typeof(DefaultQueryProvider).GetProperty("Session", BindingFlags.NonPublic | BindingFlags.Instance);

   4:     var session = sessionProperty.GetValue(queryable.Provider, null) as ISession;

   5:     var sessionImpl = session.GetSessionImplementation();

   6:     var factory = sessionImpl.Factory;

   7:     var nhLinqExpression = new NhLinqExpression(queryable.Expression, factory);

   8:     var translatorFactory = new ASTQueryTranslatorFactory();

   9:     var translator = translatorFactory.CreateQueryTranslators(nhLinqExpression, null, false, sessionImpl.EnabledFilters, factory).First();

  10://in case you want the parameters as well

  11://var parameters = nhLinqExpression.ParameterValuesByName.ToDictionary(x => x.Key, x => x.Value.Item1);

  12:  

  13:return translator.SQLString;

  14: }

   1: var query = session.Query<Product>().Where(p => p.Price > 100);

   2: var sql = query.ToSql();
