Hi!
I've the following Entity:
====
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Document implements Serializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName = "datanucleus", key = "gae.encoded-pk", value
= "true")
private String encodedKey;
@Persistent
@Extension(vendorName = "datanucleus", key = "gae.pk-name", value =
"true")
private String id;
[...]
}
====
I would like to create a query filtered by "id", but it doesn't work.
How can I make this work? Thanks for your help!
My try was the following:
====
Query query = pm.newQuery(Document.class);
query.setFilter("id == param");
query.declareParameters("String param");
try {
List<Document> results = (List<Document>) query.execute(id);
if (results.iterator().hasNext()) {
for (Document d : results) {
// do something with the Document.
// throw new RuntimeException(d.getTitle());
}
} else {
// ... no results ...
}
} catch (Exception ex) {
ex.printStackTrace();
} finally {
query.closeAll();
}
====
I know I've could get the object by Key, but there's a hierarchy in
Documents, so I can't create the key by hand.
Thanks!
