hibernate, mysql

i have the following hql query:

UPDATE Ta开发者_如何学GoskAssessment taskAssessment 
SET taskAssessment.activeFlag = false 
WHERE taskAssessment IN 
(
SELECT taskAssessment2 
FROM TaskAssessment taskAssessment2 
Where taskAssessment2.activeFlag = true 
AND taskAssessment2.patient.id 
AND taskAssessment2.needsLevel.careNeed = :careNeed
)

but its giving me errors:

You can't specify target table 'TASK_ASSESSMENT' for update in FROM clause

could anyone help me to correct the query for mysql and hibernate. thanks in advance.

To resolve You can't specify target table 'TASK_ASSESSMENT' for update in FROM clause, rewrite the query to use JOIN instead of IN (in mysql you need to write something like this):

UPDATE TaskAssessment a
INNER JOIN TaskAssessment a2 ON (a2.id = a.id)
SET a.activeFlag = 0  
WHERE a2.active_flag = 1 AND 
a2.patient_id = :patient_id AND a2.needsLevel_careNeed = :careNeed
