oh, sorry it's my bad. I did a typing mistake I wanted to type :
query.setParameter("SKDID", UserSchedule.SCHEDULE_ID_PROPERTY);Robert, you right, I'm trying to use paramters to specify Columns and so use available constants coming from Cayenne. This way, even if columns name change, nothing to change into the query. But, parameters sounds work only for values :( No working solution please ?
