JPA命名查询未返回结果

Question

当我们将marketOfferId的值设置为setParameter时，它不会返回结果。但是当我用查询中的单引号将:marketOfferId替换为实际值时，它正在运行＆＃39; BDEN3F＆＃39;。有人可以帮我解释是什么原因吗？

String iden = "BDEN3F";
TypedQuery query = em.createNamedQuery(namedQuery,MarketingOfferWEB.class).setParameter("marketOfferId",iden);

- 不工作

@NamedNativeQuery(name = MarketingOfferWEB.FIND_WEB_MARKETOFFER, query = "SELECT * FROM VW_WEB_MKT_OFFERS WHERE MKT_OFFER_UID = :marketOfferId AND TENANT_ID=1", resultClass = MarketingOfferWEB.class)

- 工作

@NamedNativeQuery(name = MarketingOfferWEB.FIND_WEB_MARKETOFFER, query = "SELECT * FROM VW_WEB_MKT_OFFERS WHERE MKT_OFFER_UID = 'BDEN3F' AND TENANT_ID=1", resultClass = MarketingOfferWEB.class)

我已经通过从TypedQuery更改为Query来解决了这个问题。

查询query = em.createNamedQuery（namedQuery，MarketingOfferWEB.class）.setParameter（“marketOfferId”，iden）;
