Hi,
I am trying to select something from DB using NHibernate, but it throws this error: Exception of type 'Antlr.Runtime.NoViableAltException' was thrown. near line 1, column 5

Error At:

IQuery query = session.CreateQuery("FROM [Player] WHERE (([Pohlavi] = 'Muž') AND ([Aktivita] = 1)) ORDER BY [Tour_Points] DESC");

Select method:

public List<Player> Get_Player_Ranking_Men()
        {
            // ---------------------------------------------------------------------------------

            // setup nhibernate configuration
            NHibernate.Cfg.Configuration config = new NHibernate.Cfg.Configuration();

            config.SetProperty(NHibernate.Cfg.Environment.Dialect, "NHibernate.Dialect.MsSql2008Dialect");
            config.SetProperty(NHibernate.Cfg.Environment.ConnectionProvider, "NHibernate.Connection.DriverConnectionProvider");
            config.SetProperty(NHibernate.Cfg.Environment.ConnectionString, "Data Source=PETA3NEC_NTBK;Initial Catalog=Beach_Volleyball;Integrated Security=True");

            // add our assembly
            config.AddAssembly("Entities");

            // setup nhibernate session
            NHibernate.ISessionFactory factory = config.BuildSessionFactory();
            NHibernate.ISession session = factory.OpenSession();

            // start nhibernate transaction
            NHibernate.ITransaction transaction = session.BeginTransaction();

            List<Player> ListPlayer = query.List<Player>().ToList();
            return ListPlayer;
        }

Class Player:
