Aliases expected length is 0; actual length is 1 on hibernate query cache

Question

String q1Str = \"SELECT parent_id FROM meta WHERE st_id = \"+childIds+\";\";
Query q1 = em.createNativeQuery(q1Str);
//q1.setHint(\"org.hibernate.cacheable\", true);         


        

Answer 1

I think this happens when the queried table does not have a primary key.
