 Post subject: outer join fetching for one-to-many association

Hello,

I have a one-to-many association in one of my entities, which is marked as lazy-"false" and outer-join="true". If I do a session.load() on the entity, I see an outer join SQL statement being executed in the log.

However, if I do a query like "select e from Entity e", there is no outer join. Instead, a separate SQL statement is exectuted for the association of every loaded object (N+1 problem). Am I doing something wrong?

thanks,
christian

HQL ignores fetch settings in the mapping. Use a fetch join in the query.

thanks for the quick reply! Did as you advised, and it works. However, I did not see any mention of this in the docs.

regards,
christian
