how we detect the existing EntityB instances they must be converted to the new Entity. With the same ID , because it's possible that many other entities have just a ID based reference with a simple 'int' field to this element. And we thought that also the real references are based on the ID . This step

How write a query in JPA2 with LEFT JOIN on INNER JOIN? select a.description, a. id , p1.description, p2.description,p3.description from action a left join action_profile ap1 on ap1. id _action=a. id inner join profile p1 on ap1. id _profile=p1. id and p1.name='?' left join action_profile ap2 on ap2. id

understand that making a query just on entity. id .field1 is efficient. Of course, making a query ... is: what about making a query just on entity. id .field2? I suppose it will not be an efficient query, because all database entries have to be checked. My assumption is based on the fact that entity. id
