Hi,
I have a problem. I have a filled database, and I want to delete some entities
from that.
The JPA query ist the following:
"DELETE FROM ConnectionEntity conn WHERE conn.stopOrPass.id IN
" +
"(SELECT sop.id FROM StopOrPassEntity sop WHERE
sop.partialTrip.id IN " +
"(SELECT prtTrip.id FROM PartialTripEntity prtTrip WHERE
prtTrip.trip.id IN : Ids))"
After executing this command derby will hang and produce 100% load on one core.
In the stacktrace below the "DRDAConnThread_11" thread is running constantly.
The database has all foreign key constants generated automatically by
EclipseLink. Could You advice where to look further?!
Thanks,
Regards,
Sandor
