NonUnique DiscoveredSqlAlias예외:중복된 sql 별칭 [ASC_]이(가) 발견되었습니다.ID] native-sql 쿼리 자동 검색 중

테이블이 3개 있습니다.CREDENTIAL_USER,CREDENTIAL_EXPIRATION그리고.ASC_DETAILS- 다음과 같이 보입니다.

CREDENTIAL_USER { ASC_ID, name, ITEM},CREDENTIAL_USER { MONTH, YEAR, ASC_ID}그리고.ASC_DETAILS {ASCID, NAME, ROLE}.

간단한 네이티브 SQL join을 실행하여 CREEDENTIAL_USER만 선택하였습니다.ASC_ID 및 ASC_DETAAILS.ASCID:

Query query = entityManager.createNativeQuery("SELECT ad.ASCID,ad.NAME,ad.CRED_EMPLOYEE_FNAME,ad.CRED_EMPLOYEE_LNAME,ad.CRED_EMPLOYEE_EMAIL,ad.CRED_EMPLOYEE_REMINDER,"+
                              " cu.*, ce.*, cl.* FROM ASC_DETAILS ad,CREDENTIAL_USER cu, CREDENTIAL_EXPIRATION ce, CREDENTIAL_LICENSE cl WHERE"+ 
                              " cu.IS_CRD_EMPLOYEE = true AND cl.IS_EMPLOYEE = true AND  ce.LICENSE_ID = cl.LICENSE_ID  AND cu.ASC_ID=ad.ASCID"+ 
                              " AND ce.LICENSE_EXP_YR >= "+year+" AND (ce.IS_LICENSE_YES=1 OR ce.IS_LICENSE_YES=3) AND cu.ASC_ID=ce.ASC_ID AND"+
                              " cu.ID=ce.EMPLOYEE_ID");
             List<Object[]> list = query.getResultList();

현지에서는 잘 작동하지만, 지금은org.hibernate.loader.custom.NonUniqueDiscoveredSqlAliasException: Encountered a duplicated sql alias [ASC_ID] during auto-discovery of a native-sql query

Credential_USER {ASC_ID, 이름, 항목}, Credential_USER {MONTH, YEAR, ASC_ID}이(가) 둘 다 ASC_를 포함합니다.그래서 ASC_.선택 쿼리에서 ID가 모호해집니다.데이터 열을 기준으로 선택하고 각 열에 대해 별도의 별칭을 지정합니다.

저도 연합체를 처음 사용할 때 이 문제에 부딪힙니다.다음과 같은 글로 해결했습니다.

...
coalesce(column_name, 'default_value') as key_word,
...

제 질문으로는

병합만 추가하면(column_name, 'default_value') 별칭이 있는 여러 값이 생성됩니다.coalesce그리고 이 오류가 발생합니다.

JpaRepository에 쿼리를 작성하는 경우 쿼리와 메서드를 저장소로 이동해야 합니다. 그러면 이 개체가 일반 개체로 반환됩니다.
