Hallo!
Ist es möglich mit Hibernate Views zu behandeln? Ich versuche nämlich gerade eine View wie eine Tabelle zu behandeln, jedoch klappt irgendetwas nicht..
Hier mal der code:
Model:
Mapping dazu:
query:
1. Wie soll man den primärschlüssel versorgen wenn die View keinen besitzt?
2. im mapping file: table=view_name?
WEnn ich die Query von oben ausführe bekomme ich die ausfürhliche meldung:
sehr aussagekräftig..
