hql查询中出现错误。java.lang.IllegalStateException:节点没有数据类型：org.hibernate.hql.ast.tree.IdentNode

我编写了以下查询

List<Integer> lkpTerritoryIdList = null;

        lkpTerritoryIdList = entityManager.createQuery("select assetTerritories from Asset a join a.assetTerritories astTerritory where a.assetId in (:assetIdListParam)")
                                           .setParameter("assetIdListParam", assetIdList).getResultList();

---

我不知道需要做什么来纠正它。请帮助朋友。

您需要

选择a.assetTerritories

？在Asset\u Territories表中，有一列名为lkp\u Territories。我只需要那个专栏。不存在资产区域表的实体类。

@CollectionOfElements
    @JoinTable(name = "ASSET_TERRITORY", joinColumns = @JoinColumn(name="ASSET_ID"))
    @Column(name="LKP_TERRITORY")
    private Set<Integer> assetTerritories = new LinkedHashSet<Integer>(0);

 java.lang.IllegalStateException: No data type for node: org.hibernate.hql.ast.tree.IdentNode
