的EclipseLink骨料和構造問題

Question

我使用的EclipseLink 2.2.1.v20110722-r9776

我有以下查詢：

TypedQuery<FundMasterDTO> secQuery = em.createQuery("SELECT new com.dto.FundMasterDTO("+" sum(appAmount), sum(redemptionPrice) from security", FundMasterDTO.class); 

我得到以下錯誤：

Exception Description: Syntax error parsing the query [SELECT new com.dto.FundMasterDTO(sum(app_amount), sum(redemption_price) from security], line 1, column 80: syntax error at [from]. 

Internal Exception: MissingTokenException(inserted [@-1,0:0='<missing RIGHT_ROUND_BRACKET>',<84>,1:80] at from); nested exception is java.lang.IllegalArgumentException: An exception occurred while creating a query in EntityManager: 

如果我不使用聚合函數，SUM，然後一切正常。如果我刪除構造函數，那麼我會返回一個列表。

由於有消息稱，你缺少一個右輪支架：

SELECT new com.dto.FundMasterDTO(sum(app_amount), sum(redemption_price)) ...
