我有以下两个查询,它们都查询同一个表。一个查询我需要所有结果,第二个我需要一个结果的子集。最后我需要两个清单。有没有办法与第二个查询共享第一个查询。

    Criteria criteriaPrStatic = this.session.createCriteria(PurchaseRequest.class).add(Restrictions.eq("inactive", false));
    //Would like to use first query again and add the restrictions without having to query the table twice. 
    Criteria criteriaPrDynamic = this.session.createCriteria(PurchaseRequest.class).add(Restrictions.eq("inactive", false));
            criteriaPrDynamic.add(Restrictions.or(
                Restrictions.eq("creator", userInfo.getUser()),
                Restrictions.eq("authorizer", userInfo.getUser())
            ));

    ProjectionList projectionList = Projections.projectionList();
    projectionList.add(Projections.groupProperty("currentState"));
    projectionList.add(Projections.rowCount());

    criteriaPrStatic.setProjection(projectionList);
    criteriaPrDynamic.setProjection(projectionList);
