HQL - hql에서 여러 동적 결합 매개 변수를 사용할 수 있습니까?

Question

는 내가이

LEFT OUTER JOIN T1.country CTRY 

WITH (CTRY.Frequency = T2.FreqId) 

처럼 내 HQL 쿼리에 조인 조건을 가지고 있지만 나는 그것이 보여주는 서버를 시작하려고 할 때마다 명명 된 쿼리에 오류가 있습니다.

나는 또한 시도했지만 결과는 동일합니다.

그래서 여러 동적 결합 조건에서 2 개의 테이블을 조인하는 올바른 구문은 무엇입니까?

자세한 쿼리처럼 보인다 ..

Answer 1

당신은 세부 쿼리를 공유 할 필요가있다. COUNTRY, FREQUENCY, TI 및 T2와 그 관계를 보여주는 매핑을 포함하는 쿼리의 일부분.

어쨌든 다음 쿼리는 나를 위해 일한 :

select 
(select c1.a from c1 where c1.a=c2.a and c1.b=c2.b and c1.c=c2.c) as some_col, 
(select c1.b from c1 where c1.a=c2.a and c1.b=c2.b and c1.c=c2.c) as some_other_col 
from 
c2 

그러나,이 방법으로, 당신은 C1에서 하나의 열을 선택할 수 있습니다.

c1에서 하나 이상의 열 값이 필요한 경우 위와 같이 유사한 조건의 조인을 한 번 더 수행해야합니다.

하위 쿼리가 둘 이상의 행을 반환 할 수있는 경우 (위 조건에서 c2에서 여러 행이 반환되는 경우), "Sub Query가 두 개 이상의 행을 반환합니다."라는 오류가 발생합니다.
