Re: [eclipselink-users] Fetchgroup usage / unfetched basic attributes
|
Hi Andrei,
thanks a lot. But then i dont understand why we have so many use cases where we define a Fetchgroup without basic attributes on a query, and despite of not included in the Fetchgroup they are loaded in the entities. What could cause this behaviour?
And is there a convenient way to build a Fetchgroup including all the basic attributes?
Best regards, Markus

Hi Markus,
If you don't use a fetch group with a query the only basic attributes
that are NOT fetched are those defined as "fetch=LAZY".
Alternatively, if you use a fetch group with a query the only basic
attributes fetched are those included in the fetch group.
Thanks,
Andrei
