from KPI kpilist0_ 
left outer join KPI_COUNTER kpilist0_2_ on kpilist0_.ID=kpilist0_2_.ID 
left outer join KPI_TEMPORARY kpilist0_3_ on kpilist0_.ID=kpilist0_3_.ID 
inner join KPI_CATEGORY kpicategor1_ on kpilist0_.ID_CATEGORY=kpicategor1_.ID

inner join STAGE stage11_ on kpilist0_2_.ID_STAGE=stage11_.ID 

where kpilist0_.ID_PROCESS_VERSION=?; 

질문입니다.

누구나 내가 무엇에 관해 말해 줄 수 있습니까?. 적용 할 추가 구성이 있습니까? 카운터 및 임시 모두에

문제와 JPA 2.1 사양을 사용하고하면 3 매핑을 가지고있다. 거짓은 매핑이 1..M -> 1임을 의미하고, true는 매핑이 0..M -> 1임을 의미하며, 후자를 원한다고 생각합니다. 이들을 사실로 변경하고 원하는 SQL을 가져 왔는지 확인하십시오.
