java - Hibernate query, QueryException exception -

i have query:

final query query2 = session.createquery("from calldetailhistoriesentity unique_id = :id or unique_id in (select linked_id calldetailhistoriesentity unique_id = :id)"); 

but have exception. why?

your entity doesn't have property named linked_id. has 1 named linkedid, though. that's should use in jpql query.

i advise stick java naming conventions: variables , methods never have underscore in java, , use camelcase. renamed unique_id uniqueid, source_caller_id sourcecallerid, etc. of course, getters , query should changed accordingly.

the next step realize whole point of jpa/hibernate have graph of entities, interconnected using associations. should probaby not have linkedid attribute of type string in entity, rather manytoone or onetoone association entity. that's allwos navigating graph of entities in code, , using joins in queries.
