Hi..
Is it possible to map multiple objects to one
table?
I tried it and it gave me wrong objects!
:-/
I have 1 table, which is modelled by 2 different
objects.
Reason for this is that the 2nd object hold large
BLOB data, so I'd like to keep them separate
for performance reasons.
My XML is something like this
<hibernate-mapping>
<class name="com.nic.interx.model.Broadcast" table="BROADCASTS"> <id name="id" column="ID" type="integer"> <generator class="sequence"> <param name="sequence">GEN_BROADCAST</param> </generator> </id> <property name="name" column="NAME" type="string"/> <property name="totalCount" column="TOTAL_COUNT" type="integer"/> <property name="description" column="DESCRIPTION" type="string"/> </class> <class
name="com.nic.interx.model.BroadcastTemplate"
table="BROADCASTS">
<id name="id" column="ID" type="integer"> <generator class="assigned"/> </id> <property name="data" column="BROADCAST_TEMPLATE" type="com.nic.hibernate.types.BinaryType"/> </class> </hibernate-mapping> As for my query..
Broadcast bc = (Broadcast)session.load( Broadcast.class,
broadcastId);
BroadcastTemplate bct = (BroadcastTemplate)session.load(
BroadcastTemplate.class, broadcastId);
Since Broadcast and BroadcastTemplate shares the same primary key ID, and
table,
Hibernate seems to be confused and actually returned me a Broadcast object
in the 2nd query.
(It should be returning BroadcastTemplate object instead)
