Olivier,

How can I force the index on a delete ?
I try to find the right syntax but it's not working...
I tried, the "FORCE" or the IGNORE INDEX(PRIMARY) but it fails..

This one is working :
DELETE t1 FROM cid_operation t1 FORCE INDEX (FK_CID_OPERATION_ENV_CASE)
JOIN cid_operation t2 USING (id_env_case)
WHERE (t2.id_env_case = 4448) AND (t2.id BETWEEN 15006449 AND 15007342)

But I'm really not sure of the impacts
