SQL查詢在休眠中發生異常

Question

我有一個DAO方法。

public ScrollableResults getPRecords(StatelessSession statelessSession) throws UnsupportedEncodingException{ 
    Criteria crit = statelessSession.createCriteria(APRecord.class, "apr"); 
    crit.createAlias("mAsset", "aId", Criteria.INNER_JOIN); 
    SQLQuery q=statelessSession.createSQLQuery("select distinct aId1_.aId, this_.pNAME, " + 
      "this_.kNum," + 
      "from " + 
      "AP_CPView " + 
      "this_ inner join A_MAView aId1_ " + 
      "on this_.agentG= aId1_.AgentG "); 
    return q.scroll(ScrollMode.FORWARD_ONLY); 
} 

查詢在SQL中運行正常，但試圖在Hibernate中寫入它給我錯誤。

我嘗試了不同的東西，但最終成爲一個錯誤。有人可以告訴我爲什麼這個人給我一個錯誤？

你有額外的昏迷。

改變這一行：

"this_.kNum," + 

到

"this_.kNum" +
