Hi all
I try to get part of a collection over hql. In the Hibernate tutorial it is sugested to use the criterias to get the data from a collection. As we are using JBoss Seam framework we rely on EJB.
| @Entity
| // ...
| class SoftwareInventoryObject {
| // other code
| String name;
|
| @OneToMany
| List<SoftwareInventoryObjectPart> parts;
|
| // Getter & Setter
| }
|
| @Entity
| class SoftwareInventoryObjectPart {
| // other code
| String name;
| // other code
| }
|
My first try was to get the SoftwareInventoryObject over this query:
"from SoftwareInventoryObject sio where sio.name = 'foo' and sio.parts.name = 'bar'". Unfortunately this doesn't work. How do I get this running?
Thank you very much for your help,
Thierry
