NHibernate Identity fields

Question

Getting started with NHibernate

How can I generate identity fields in nHibernate using Hilo algorithm?

Answer 1

use class="hilo":

<generator class="hilo">

example:

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" namespace="NHibernate__MyClass" assembly="NHibernate__MyClass">
  <class name="MyClass" table="MyClass">
    <id name="Id" type="int" column="ID">
      <generator class="hilo">
    </id>
    <property name="Name">
      <column name="Name" not-null="true" />
    </property>
    <property name="Value">
      <column name="Value" not-null="true" />
    </property>
  </class>
</hibernate-mapping>

I simplified:

<id name="Id">
  <column name="ID" sql-type="int" not-null="true"/>
  <generator class="hilo" />
</id>

to:

<id name="Id" type="int" column="ID">
    <generator class="hilo">
</id>

You could have a syntax error of some sort that is confusing NHibernate.
If you could provide more detail about the code that is executing before the failure or anything else you might think is important, that could speed the rate at which your problem is resolved.

I haven't watched the screencasts yet. But Summer of nHibernate should help you.

I am sorry - I am not answering your original question.
