javax.persistence.TypedQuery.getSingleResult（）NoResultException，即使记录存在

javax.persistence.TypedQuery.getSingleResult（）NoResultException，即使记录存在。下面的代码很好，记录率为99%，但结果为1%。DB是SQLServer2016。当我使用javax.persistence.Query createNativeQuery和Query.getResultList（）时，我有一个模板列表

你可以通过调试来解决这个问题。在本例中，您将在JPA提供者日志中查看调用的SQL。FWIW JPQL以“SELECT{alias}”开头。谢谢Neil，调用的sql是正确的，并且sql在从查询浏览器执行时正在获取数据。@Sandepkumar编辑并粘贴实体代码

public TApplicationDocument getDocumentById(int id) {  
        TypedQuery<TApplicationDocument> q = getEntityManager().createQuery(  
                "FROM TApplicationDocument  where transientKey =   :transientKey", TApplicationDocument.class);  
        q.setParameter("transientKey", id);  
        TApplicationDocument d=null;  
        try {
            d = q.getSingleResult();
            System.out.println("AppDocumentTitle  "+d.getAppDocumentTitle());
        } catch (NoResultException e) {
            logger.debug("No result forund for... "+id);
            System.out.println("No result forund for... "+id);
        } catch (Exception e) {
            logger.debug(" Tapp Dao IMple Exception for... "+id);
        }
return d;
    }
