私はこの文脈で非常に奇妙な問題を抱えています。
これは親オブジェクトです（注文見出し、IEntityは空のインターフェースです）：
public class OrderEntity : IEntity
{
public virtual int prg_ordine { get; set; }
public virtual int num_anno { get; set; }
public virtual int num_doc { get; set; }
public virtual String num_doc_esteso { get; set; }
public virtual DateTime? dat_doc { get; set; }
public virtual String cod_clifor_c { get; set; }
public virtual String rag_soc { get; set; }
public virtual DateTime? dat_evasione { get; set; }
public virtual decimal qta_peso_lordo_kg { get; set; }
public virtual decimal qta_peso_netto_kg { get; set; }
public virtual decimal qta_totale { get; set; }
public virtual String ind_sped { get; set; }
public virtual String ind_sped_div { get; set; }
public virtual String rag_soc_div { get; set; }
public virtual String cod_agente { get; set; }
public virtual String des_agente { get; set; }
public virtual String cod_pag { get; set; }
public virtual String des_pag { get; set; }
public virtual String ind_stato_evas { get; set; }
public virtual int cod_commessa_num { get; set; }
public virtual String des_num_esterno { get; set; }
public virtual ClientEntity client { get; set; }
public virtual ICollection<OrderItemEntity> orderItems { get; set; }
}
これは子オブジェクト（順序行）です：
public class OrderItemEntity : IEntity
{
public virtual int prg_ordine { get; set; }
public virtual int prg_ordine_riga { get; set; }
public virtual String cod_art_completo { get; set; }
public virtual String cod_clifor_c { get; set; }
public virtual String rag_soc { get; set; }
public virtual int num_doc { get; set; }
public virtual String num_doc_esteso { get; set; }
public virtual DateTime? dat_doc { get; set; }
public virtual String cod_art { get; set; }
public virtual String tipo_art { get; set; }
public virtual int prg_art { get; set; }
public virtual String ind_tiporiga { get; set; }
public virtual String cod_um_doc { get; set; }
public virtual String des_articolo_riga { get; set; }
public virtual decimal qta_daevadere { get; set; }
public virtual decimal qta_evasa { get; set; }
public virtual decimal qta_ordine { get; set; }
public virtual DateTime? dat_evasione { get; set; }
public virtual DateTime? dat_evas_riga { get; set; }
public virtual String note { get; set; }
public virtual bool gestisci_pezzatura { get; set; }
public virtual int numero_pezzi { get; set; }
public virtual decimal quantita_pezzo { get; set; }
public virtual string commessa { get; set; }
public virtual int num_riga { get; set; }
public virtual ArticoloDisponibilitaEntity articoloDisponibilita { get; set; }
public virtual OrderEntity order { get; set; }
public override bool Equals(object obj)
{
return base.Equals(obj);
}
public override int GetHashCode()
{
return base.GetHashCode();
}
}
これらは、参照される他の2つのオブジェクトです。
public class ClientEntity : IEntity
{
public virtual String cod_clifor { get; set; }
public virtual String des_ragsoc { get; set; }
public virtual String indirizzo { get; set; }
public virtual String codice_e_descrizione
{
get
{
return cod_clifor + " - " + des_ragsoc;
}
}
public virtual ICollection<OrderEntity> orders { get; set; }
}
public class ArticoloDisponibilitaEntity :IEntity
{
public virtual String cod_art_completo { get; set; }
public virtual decimal qta_esistente { get; set; }
public virtual decimal qta_in_distinte_lavorazione { get; set; }
public virtual decimal qta_in_distinte_aperte { get; set; }
public virtual decimal qta_libera_alla_vendita()
{
var ret = qta_esistente - qta_in_distinte_aperte - qta_in_distinte_lavorazione;
if(ret < 0)
ret = 0;
return ret;
}
}
FluentnHibernateマッピングクラスは次のとおりです。

このクエリ：
return All().FetchMany(x => x.orderItems).Fetch(x => x.client).Where(x => x.cod_clifor_c == filters.clientId).ToList();
このクエリを実行します。

これは完全に問題ありません。
問題は、上記のクエリの後に、次のようにORDERROWごとに1つのクエリが実行されることです。
SELECT orderiteme0_.prg_ordine_riga as prg1_12_0_,

WHERE orderiteme0_.prg_ordine_riga = 1 /* @p0 */
and orderiteme0_.prg_ordine = 22 /* @p1 */
これは予期せぬことであり、望ましくありません。マッピングに何か問題があるのではないかと思いますが、それはすべて私にとって良いことのようです。これが発生する理由とそれを回避する方法についてのヒントはありますか？
ありがとう、マリオ
