NonUniqueDiscoveredSqlAliasException: обнаружен дублированный псевдоним sql [ASC_ID] при автоматическом обнаружении запроса native-sql

У меня есть три таблицы CREDENTIAL_USER, CREDENTIAL_EXPIRATION и ASC_DETAILS - которые выглядят так:

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

Я выполнил простое собственное SQL-соединение, чтобы выбрать только CREDENTIAL_USER.ASC_ID и ASC_DETAAILS.ASCID как:

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();

Работает нормально на локальном, но получая org.hibernate.loader.custom.NonUniqueDiscoveredSqlAliasException: Encountered a duplicated sql alias [ASC_ID] during auto-discovery of a native-sql query

ОТВЕТЫ

Ответ 1

CREDENTIAL_USER {ASC_ID, имя, элемент управления}, CREDENTIAL_USER {МЕСЯЦ, ГОД, ASC_ID} оба содержат ASC_ID, поэтому ASC_ID становится неоднозначным в выборе запроса. Выберите свой столбец данных и укажите отдельный псевдоним для каждого столбца.

Ответ 2

При использовании coalesce в первый раз, я также сталкиваюсь с этой проблемой. Я решил это, написав:

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

в моем запросе. Добавление только coalesce (column_name, 'default_value') создает несколько значений с именем coalesce, и эта ошибка возникает. надеюсь, что это поможет кому-то вроде меня.
