NonUniqueDiscoveredSqlAliasException: Un alias SQL dupliqué [ASC_ID] a été rencontré lors de la découverte automatique d'une requête SQL native.

J'ai trois tables CREDENTIAL_USER, CREDENTIAL_EXPIRATION et ASC_DETAILS - dont l'apparence est la suivante:

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

J'ai exécuté une jointure SQL native simple pour sélectionner uniquement CREDENTIAL_USER.ASC_ID et ASC_DETAAILS.ASCID en tant que:

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();

CREDENTIAL_USER {ASC_ID, nom, ITEM}, CREDENTIAL_USER {MOIS, ANNÉE, ASC_ID} Contiennent tous les deux ASC_ID de sorte que ASC_ID devient ambigu dans la requête de sélection . Sélectionnez votre colonne de données et attribuez un alias distinct pour chaque colonne.

Lors de la première utilisation de coalesce, je rencontre également ce problème. Je l'ai résolu en écrivant:

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

dans ma requête. L'ajout de just coalesce (nom_colonne, 'valeur_faut') crée plusieurs valeurs portant le nom coalesce et cette erreur se produit. espérons que cela aide pour quelqu'un comme moi.
