[google-appengine] JDO Query - Find error
Hello,
I get following error:
Problem with query SELECT FROM de.hsowl.google.evaluation.model.Appointment
WHERE userPara == createdBy PARAMETERS String userPara: Unexpected expression
type while parsing query: org.datanucleus.query.expression.ParameterExpression
the Method:
public ListAppointment getAppointments(User user)
{
PersistenceManager pm = PMF.get().getPersistenceManager();
Query q = pm.newQuery(Appointment.class);
q.setFilter(userPara == createdBy);
q.declareParameters(String userPara);
ListAppointment queryResult = (ListAppointment) q.execute(user.
getUserId());
return queryResult;
}
The important part of the object
@PersistenceCapable(detachable = true)
public class Appointment implements javax.jdo.listener.StoreCallback
{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Long id;
@Persistent
private String createdBy; //contains the userid
...
}
How can I declare the Parameter correct?
Have a nice day
Benjamin

I will try. At the moment it works... Am Donnerstag, 6.

What could it be? The verylongstring URL is fine, since that's the way the blobstore handles uploads. However, you should be getting the redirect. Can you use your browser's developer tools (under Chrome, it's under the Tools Developer Tools menu) to see what redirects the client is getting? - -Vinny P Technology Media Advisor Chicago, IL App Engine Code Samples: http://www.learntogoogleit.com -- You received this message because you are subscribed to the Google Groups Google App Engine group.
