just wonder, how can I get the newly inserted record back, the primary key (ID) is generated by a sequence. e.g like this

<id name="id" type="long" column="order_id" unsaved-value="null" access="field">
<generator class="sequence">
<param name="sequence">order_id_seq</param>
</generator>
</id>

Thanks.

how do I know the ID for the newly inserted record?

you should still have a reference to the object.

you call saveOrUpdate(object)
then you can call object.getId();
