Hi,
iirc the deleteByQuery(...) method, just produces SQL that is forwarded to the database directly without any check on auto-delete settings. This method does not
even remove deleted objects from cache.

Hi,
no, I don't get an error.
When using "PersistenceBroker.deleteByQuery(QueryByCriteria q)" the
"parent" object is deleted, not the referenced objects.
I didn't check the OJB code, but I guess this is normal behaviour for
"deleteByQuery".
When I read the object first with
"PersistenceBroker.getObjectByQuery(QueryByCriteria q)" and delete the
received object everything is fine.
Best regards.............Frank

Hi,
right, and if it is not deleted you could get run time error due to the
FK .
Anyway it is better you set the auto-delete to "object", that is the
same, but "true" and "false" are deprecated .

Hi Alessandro,
thank you for the quick response.
auto-delete is set to "true".
Otherwise "PersistenceBroker.delete(obj)" wouldn't delete the
referenced collections either.
Best regards.............Frank

Hi,
it depends on the auto-delete settings:

Hi community,
I'm using PersistenceBroker of OJB1.0.3.
Is it correct that "PersistenceBroker.deleteByQuery(QueryByCriteria
q)"
does not delete objects referenced by a collection-descriptor?
Whene I use
(1) Object obj = PersistenceBroker.getObjectByQuery(QueryByCriteria
q)
(2) PersistenceBroker.delete(obj)
it works.
Thanks
Frank
