Re: [eclipselink-users] Potential bug in EclipseLink

Hello Michael,
Because you are using x.claim.id, this causes an inner join to be used.
You will need to specify an outer join in the from clause:
SELECT x FROM Depot x outer join x.claim claim WHERE x.scenario = :currentScenario and (claim is null or claim.id in(%s))
Best Regards,
Chris

Hello,
JPQL-Query:
SELECT x FROM Depot x WHERE x.scenario = :currentScenario and (x.claim is null or x.claim.id in

is transalted to the following SQL:
SELECT t1.depot_id, t1.bot_pump_rate, t1.available, t1.ext_id, t1.jdo_version, t1.name3,
t1.avg_wait, t1.top_pump_rate, t1.nme, t1.name2, t1.alt_ex_id, t1.depot_type_id, t1.claim_id,
t1.schedule_id, t1.corporate_id, t1.measure_id, t1.lcation_id, t1.scenario_id, t0.claim_id,
t0.description, t0.nme
FROM claim t0, depot t1
WHERE (((t1.scenario_id = ?)
AND ((t1.claim_id IS NULL) OR (t0.claim_id IN (?, ?, ?, ?, ?, ?))))
AND (t0.claim_id = t1.claim_id))
This is not correct because the natural join of the claim table suppresses the lines in t1 with
a claim_id of NULL, but these lines must also be selected.
Do I fail or did EL fail here?
Kind Regards,
Michael
