Hello,

I was looking for the ability to use inner join instead left outer join on the collections fetched using an EntityGraph?

Indeed, when collections specified in my graph are fetched, Hibernate always generates left outer join...

Is this even possible or should I always write my queries without graph?

I read litterature on the Internet and always saw that left outer are used...

I don't think it's possible because the entity graph fetches additional data.
This is the same with FetchType.EAGER which either uses a LEFT OUTER JOIN or a sub-select.
EAGER fetching cannot work with INNER JOIN because it might filter out the root entity as well.
