I need a help with OQL query. I modified my old application from University and I have problem with OQL. There is some error and I can not repair this. FROM BeekeeperDiaryapplicationKarolChwalek.Apiaries AS MedRec INNER JOIN MedRec/BeekeeperDiaryapplicationKarolChwalek.ApiariesRecordBeekeeperUser/BeekeeperDiaryapplicationKarolChwalek.BeekeeperUser AS Puser GROUP By Puser/Name SELECT COUNT (MedRec/Apiaries_name) as MedRecCount, Puser/Name AS PuserName Error show me that the path does not resolve to a column and cannot resolve attribute.
