JPQL（Hibernate 4.3.6）子選擇查詢不起作用

Question

我有一個問題，可以輕松執行兩個單獨的查詢； 第一個獲得ID集，第二個在“ IN”子句中使用這些ID； 但是，當我嘗試將兩者與一個子查詢合並為一個查詢時，它將不起作用。

這有效：

public List<Lead> findLeadsBySupplierAndStatus(List<Integer> supplierIds, StatusCode status){

    Query query = entityManager.createQuery("select ss.id from StateSupplier ss where ss.supplier.id in :supplierIds");
    query.setParameter("supplierIds", supplierIds);

    @SuppressWarnings("unchecked")
    List<Integer> result = (List<Integer>)query.getResultList();

    Query query2 = entityManager.createQuery("from Lead l where l.stateSupplier.id in :ids and l.leadStatus.id= :statusId");
    query2.setParameter("ids", result);
    query2.setParameter("statusId", status.getDbId());

    @SuppressWarnings("unchecked")
    List<Lead> result2 = (List<Lead>)query2.getResultList();
    return result2;
}

但這不是：

public List<Lead> findLeadsBySupplierAndStatus(List<Integer> supplierIds, StatusCode status){
    Query query = entityManager.createQuery("select l from Lead l where l.stateSupplier.id in (select ss.id from StateSupplier ss where ss.supplier.id in :supplierIds) and l.leadStatus.id= :statusId");
    query.setParameter("supplierIds", supplierIds);
    query.setParameter("statusId", status.getDbId());

    @SuppressWarnings("unchecked")
    List<Lead> result2 = (List<Lead>)query.getResultList();
    return result2;
}

我得到以下異常：

有沒有一種方法可以使單個查詢僅與JPA類（EntityManager，查詢等）一起使用？

每個潛在客戶都有一個FK（@ManyToOne）到StateSupplier（stateSupplier），一個FK（@ManyToOne）到LeadStatus（leadStatus），每個StateSupplier都有一個FK（@ManyToOne）到供應商（供應商）。 我認為該模型非常簡單，不需要實體的源代碼，因為問題只是合並了可單獨工作的查詢。

Answer 1

為什么不在查詢中使用聯接（顯式或隱式）而不是子查詢

select l from lead l inner join l.stateSupplier ss 
where ss.supplier.id in :suppllierIds and l.leadStatus.id =:statusId
