Question

我有一个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);
}

查询在SQL中运行正常但是尝试在Hibernate中编写它会给我带来错误。

我尝试过不同的东西，但最终却是错误的。有人能说出为什么来自我的错误吗？

你有额外的昏迷。

更改此行：

<button class="button btn-custom button-full button-assertive icon icon-left ion-android-bicycle no-border red-custom no-margin">

       <a href="#/category/sport"></a>
</button>

到

"this_.kNum," +
