Question

SQLクエリに問題があります。私は、クエリを構築するためにHibernate Criteriaを使用しています。特定の間隔（binSize）で値を四捨五入してグループ化して、データベースからいくつかのビンを作成します。私は、クエリとSQLで直接それをしようとすると、これは素晴らしい作品：

 
SELECT floor(phiTorsionAngle/2) * 2 as phiTorsionAngleBin, 
     floor(psiTorsionAngle/2) * 2 as psiTorsionAngleBin, 
     floor(phiTorsionAngle/2) + 180 as phiTorsionAngleBinIndex, 
     floor(psiTorsionAngle/2) + 180 as psiTorsionAngleBinIndex, 
     count(*) as numberOfResidues 
FROM residue 

WHERE phitorsionangle IS NOT NULL 
    AND psitorsionangle IS NOT NULL 

GROUP BY phiTorsionAngleBin, psiTorsionAngleBin 

しかし、ときに私はそれが失敗したHibernateの基準でそれを試してみてください。これは、クエリを作成するためのコードです：

ScrollableResults phiPsiBins = createCriteria() 
.setProjection(Projections.projectionList() 
     .add(Projections.sqlGroupProjection(
     "floor(phiTorsionAngle/" + binSize + ") * " + binSize + " as phiTorsionAngleBin, " + 
     "floor(psiTorsionAngle/" + binSize + ") * " + binSize + " as psiTorsionAngleBin, " +   
     "floor(phiTorsionAngle/" + binSize + ") + 180 as phiTorsionAngleBinIndex, " + 
     "floor(psiTorsionAngle/" + binSize + ") + 180 as psiTorsionAngleBinIndex, " + 
     "count(*) as numberOfResidues", 
     "phiTorsionAngleBin, psiTorsionAngleBin", 
     new String[] {"phiTorsionAngleBin", "psiTorsionAngleBin", "phiTorsionAngleBinIndex", "psiTorsionAngleBinIndex", "numberOfResidues"}, 
     new Type[] {Hibernate.DOUBLE, Hibernate.DOUBLE, Hibernate.INTEGER, Hibernate.INTEGER, Hibernate.INTEGER}))) 
.add(Restrictions.isNotNull("phiTorsionAngle")) 
.add(Restrictions.isNotNull("psiTorsionAngle")) 
.setResultTransformer(Transformers.aliasToBean(PhiPsiBinResult.class)) 
.setCacheMode(CacheMode.IGNORE) 
.scroll(ScrollMode.FORWARD_ONLY); 

これは、以下の完全なスタックトレースで、私は取得していますエラーメッセージです：

私はGROUPにphiTorsionAngleとpsiTorsionAngleを追加してみましたBY、これはうまくいくようですが、それは意味をなさないものです。私はphiTorsionAngleのすべての可能な値でグループ分けしたくないので、私はビン全体をグループ化したいと思うでしょう。おそらく、phiTorsionAngleのための多くの異なる値を含んでいます。どうしてこのエラーが出るのですか？どうすれば回避できますか？

更新：実際にはまだ終了していないのにクエリを実行しようとはしませんでした。そして、ヒープスペースエラーが発生しました.PiTorsionAngleとpsiTorsionAngleグループ化するには今すぐ完全に質問です:)
