Sql server Odata>EF>从表中选择SQL

我的POCO表定义如下，因为我希望最终将其用作Dynamics CE上的虚拟实体，所以它应该能够在以下集合的OData端点上使用$expand

public partial class ak_iglead_V
{

    [Key]
    public Guid ak_igLeadId_V { get; set; }  //the pk
     ....
    public virtual ICollection<ak_Match> ak_MatchLead { get; set; }

}

public partial class ak_Match
{
    [Key]
    [Column(Order = 0)]
    public Guid MatchId { get; set; }
    public Guid ak_LeadId { get; set; } //Foreign key to 
    public Guid? ak_matchLeadId { get; set; } //forreign key to 
    public Guid? ak_matchContactId { get; set; }
    public decimal? ak_Confidance { get; set; }
    public string ak_Name { get; set; }
    [SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly"),ForeignKey("ak_LeadId")]
    public virtual ak_iglead_V ak_iglead_V { get; set; }
    [SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly"),ForeignKey("ak_matchLeadId")]
    public virtual ak_iglead_V ak_iglead_V_matched { get; set; }
}

这是代码片段：

`public List<ak_Match> Matches { get; set; }
 public void Initialize()
{
    var matches = from m in db.akMatches
                  select m;
    this.Matches= matches.ToList() ;
`

并生成异常，因为它找不到应该是集合的列

它能不能在SQL中以某种方式被忽略？ 不知怎的，因为这是同一张桌子的钥匙，我想它不知怎么搞糊涂了

System.Data.Entity.Core.EntityCommandExecutionException： 执行命令定义时出错。有关详细信息，请参见内部异常

SqlException:

列名称“ak_iglead_V_ak_igLeadId_V”无效 列名“AKU IGLEADU V_AKU igLeadId_Vmatched”无效

导航属性和外键属性之间的关系不符合EF的约定，因此需要显式配置关系。例如，使用。

AKU匹配表应处理同一AKU igLead v实体的外键： 请注意指向命名的nvigation属性的[ForeignKey]属性

public partial class ak_Match //V_CE_ak_match
{
    [Key]
    public Guid ak_MatchId { get; set; }

    [ForeignKey("FK_ak_Match_ak_igLead_V")]
    public Guid ak_LeadId { get; set; }

    [ForeignKey("FK_ak_Match_ak_igLead_Matched")]
    public Guid? ak_matchLeadId { get; set; }
    public Guid? ak_matchContactId { get; set; }
    public decimal? ak_Confidance { get; set; }
    public string ak_Name { get; set; }

    [InverseProperty("ak_MatchLead")]
    public virtual ak_iglead_V FK_ak_Match_ak_igLead_V { get; set; }

    [InverseProperty("ak_MatchedLead")]
    public virtual ak_iglead_V FK_ak_Match_ak_igLead_Matched { get; set; }
}

@david-这为我指明了正确的方向。

你能提供DDL表吗？它有外键吗？我添加了带有PK的“ak_iglead_V”表，两个字段“ak_LeadId”和“ak_matchLeadId”是该表的外键。

public partial class ak_Match //V_CE_ak_match
{
    [Key]
    public Guid ak_MatchId { get; set; }

    [ForeignKey("FK_ak_Match_ak_igLead_V")]
    public Guid ak_LeadId { get; set; }

    [ForeignKey("FK_ak_Match_ak_igLead_Matched")]
    public Guid? ak_matchLeadId { get; set; }
    public Guid? ak_matchContactId { get; set; }
    public decimal? ak_Confidance { get; set; }
    public string ak_Name { get; set; }

    [InverseProperty("ak_MatchLead")]
    public virtual ak_iglead_V FK_ak_Match_ak_igLead_V { get; set; }

    [InverseProperty("ak_MatchedLead")]
    public virtual ak_iglead_V FK_ak_Match_ak_igLead_Matched { get; set; }
}
