Need help with Hibernate? Read this first:

Hibernate version:3.13

Mapping documents:

cascade="save-update">
<key column="ITEM_ID"/>
<one-to-many class="Bid"/>
</set>

Code between sessionFactory.openSession() and
session.save(Item);
session.close():

Full stack trace of any exception that occurs:

Name and version of the database you are using:

The generated SQL (show_sql=true):
insert into ITEM (NAME, ID) values (?, null);
update BID set NAME=? where ID=?
Debug level Hibernate log excerpt:

I want to insert "items" and it's "bids"
cascade="save-update" is also added. but hibernate generate "update BID" instead of "insert BID"
some body know why?

Thanks

If bid is getting updated it could be because you have set the id for bid already. Hibernate would then consider that it is already in the database and would therefore update instead of insert. If you are using generator class="assigned" for Bid, then you would need to use version or timestamp.
