NHibernate插入表

我如何使用CreateQuery()将数据插入表？

c#class

namespace NHibernateTutorial
{
    public class Customer
    {
        public virtual int CustomerId { get; set; }
        public virtual string FirstName { get; set; }
        public virtual string LastName { get; set; }           
    }
}

    var configuartion = new Configuration();
                configuartion.DataBaseIntegration(x =>
                    {
                        x.ConnectionString = @"Data Source=NH;Initial Catalog=NHibernate;Integrated Security=False;Connect Timeout=15;Encrypt=False;TrustServerCertificate=False";
                        x.Driver();
                        x.Dialect();
                        x.LogFormattedSql = true;
                        x.LogSqlInConsole = true;
                        x.AutoCommentSql = true;
                    });

                configuartion.AddAssembly(Assembly.GetExecutingAssembly());

                var sessionFactory = configuartion.BuildSessionFactory();
                using (var session = sessionFactory.OpenSession())
                { 
                 var query = session.CreateQuery("INSERT INTO Customer (FirstName, LastName) select i.FirstName, i.LastName from CustomerOld i"); 
                 query.ExecuteUpdate();
                }

在这个例子中我从另一个表复制行,但我需要创建新行,我该怎么做？
