Bonjour,

J'aurais peut-etre plus de chance dans cette section francaise... :-)

Merci.
Ced.

But if my criteria search returns 100 results, then hibernate will execute 100 queries to populate each entity relationship... why not using a single query with a "IN" subquery which contains the IDs from the query search?

La solution doit être dans le fetching mode, mais je n'ai pas encore effectué beaucoup de test des différents paramétrages.

Dynamic association fetching doc v3
Fetching strategies doc v3

javadoc :
Criteria.setFetchMode 2.1
Criteria.setFetchMode 3.0

merci.

On dirait que j'ai besoin d'un FetchMode a "subselect" pour ma collection retourne du criteria search, mais ca c'est implemente pour Hibernate 3.
