Hibernateの基準の問題：解決できませんでしたプロパティ：

Question

私は少し問題に直面している：私はcampaignProgressionの平均が100の使用基準等しいキャンペーンを選択します：ここに

は、SQLでクエリです：

ここ

SELECT * FROM campagne as camp, progression_campagne as campProg 
where camp.id = campProg.current_campaign and 
(SELECT avg(campaign_progression) FROM progression_campagne)=100 group by camp.id; 

は基準での翻訳です：

Criteria crit = getSessionFactory().getCurrentSession().createCriteria(Campagne.class); 
     crit.createAlias("progressionCampagnes", "prog"); 
     crit.setProjection(Projections.projectionList().add(Projections.groupProperty("prog.campagne")).add(Projections.avg("prog.campaignProgression"),"moy")); 
     crit.add(Restrictions.eq("moy", new Float(100))); 

しかし、私はこのエラーを取得しています：

org.hibernate.QueryExceptionを：プロパティを解決できませんでした：MOYの： ma.dataprotect.sensipro.model.Campagne

編集：

はCampaignとProgressionCampaignのモデルクラスは以下のとおりです。

Answer 1

[OK]を、あなたの基準では、HAVING機能を実現するために、サブクエリを使用する必要があります。これはコードです：

 DetachedCriteria innerCrit = DetachedCriteria.forClass(Campagne.class); 
     innerCrit.createAlias("progressionCampagnes", "prog"); 
     innerCrit.setProjection(Projections.avg("prog.campaignProgression"); 
     innerCrit.add(Restrictions.eqProperty("id", "campOuter.id")); 

     DetachedCriteriaouterCrit = DetachedCriteria.forClass(Campagne.class, "campOuter"); 
     outerCrit.add(Subqueries.eq(100, innerCrit)); 

これは、元のSQL結果を取得する必要があります。
