NonUniqueDiscoveredSqlAliasException：ネイティブSQLクエリの自動検出中に重複したSQLエイリアス[ASC_ID]が発生しました

3つのテーブルがありますCREDENTIAL_USER、CREDENTIAL_EXPIRATIONおよびASC_DETAILS-次のようなもの：

CREDENTIAL_USER { ASC_ID, name, ITEM}、CREDENTIAL_USER { MONTH, YEAR, ASC_ID}およびASC_DETAILS {ASCID, NAME, ROLE}.

単純なネイティブSQL結合を実行して、CREDENTIAL_USER.ASC_IDおよびASC_DETAAILS.ASCIDのみを次のように選択しました。

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();

ローカルで問題なく実行されていますが、org.hibernate.loader.custom.NonUniqueDiscoveredSqlAliasException: Encountered a duplicated sql alias [ASC_ID] during auto-discovery of a native-sql query

CREDENTIAL_USER {ASC_ID、名前、ITEM}、CREDENTIAL_USER {MONTH、YEAR、ASC_ID}の両方にASC_IDが含まれているため、選択クエリでASC_IDがあいまいになります。データ列を賢明に選択し、各列に個別のエイリアスを指定します

初めて合体を使用するとき、私もこの問題に遭遇します。私は書いてそれを解決しました：

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

私のクエリで。 Coalesce（column_name、 'default_value'）を追加すると、coalesceという名前の値がいくつか作成され、このエラーが発生します。これが私のような人に役立つことを願っています。
