在NHibernate中插入数据但对标识符不感兴趣

Question

I'm getting data from a webserver and insert them in my PostgreSQL database. My table has an id as serial , which is an auto-increment value handled by a sequence in PostgreSQL.

I'm just inserting data and don't do anything with the data after that point. So I'm not interested in the value of the ID. I see that NHibernate is calling select nextval for every insert. How to tell NHibernate it is not necessary? It just needs to send an insert-statement and move on.

In my xml I have:

<id name="Id" column="id">
  <generator class="native">
    <param name="sequence">id_seq</param>
  </generator>
</id>

I'm using this xml/class in other parts as well and then I get the data and then I do need the value of id.

Have you tried with a stateless session? http://nhibernate.info/doc/nhibernate-reference/batch.html#batch-statelesssession
