实体框架无效列(数据库或代码中不存在该列)

所以我看到了很多像我这样的问题。 但是没有一个答案是有效的。每当我尝试更新实体时，我都会收到无效列异常：

[SqlException （0x80131904）：列名"ssma$rowid"无效。 列名"ssma$rowid"无效。

这是从哪里来的？我已经重新生成/重建/清理/删除了表，但仍然出错。数据库没有具有此名称的列。 我该如何解决这个问题？

这是我的实体，它没有外键：

public interface IDataContext : IDisposable
{
    IDbSet<Organization> Organizations { get; set; } // organizations
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
        base.OnModelCreating(modelBuilder);
        modelBuilder.Configurations.Add(new OrganizationConfiguration());
}
public partial class Organization : BaseEntity
{
    public long Id { get; set; } // id (Primary key)
    public long? ReportTypeId { get; set; } // report_type_id
    public byte Active { get; set; } // active
    public long? TimeZoneId { get; set; } // time_zone_id
    public string Name { get; set; } // name
    public string MainContact { get; set; } // main_contact
    public string Address { get; set; } // address
    public string City { get; set; } // city
    public string StateId { get; set; } // state_id
    public string StateName { get; set; } // state_name
    public string ZipCode { get; set; } // zip_code
    public string Phone { get; set; } // phone
    public string Fax { get; set; } // fax
    public string Email { get; set; } // email
    public string Website { get; set; } // website
    public short IncludeContactType { get; set; } // include_contact_type
    public short NursingNote { get; set; } // nursing_note
    public DateTime UpdatedAt { get; set; } // updated_at
    public DateTime CreatedAt { get; set; } // created_at
    public string OfficeBackline { get; set; } // officeBackline
    public string Pharmacy { get; set; } // pharmacy
    public string PharmacyPhone { get; set; } // pharmacyPhone
    public string PharmacyBin { get; set; } // pharmacyBin
    public string PharmacyGroup { get; set; } // pharmacyGroup
    public string Dme { get; set; } // dme
    public string DmePhone { get; set; } // dmePhone
    public string LanguageLine { get; set; } // languageLine
    public string LanguageLinePin { get; set; } // languageLinePin
    public string Announcements { get; set; } // announcements
    public string Skillname { get; set; } // skillname
    public string OutboundSkill { get; set; } // outbound_skill
    public string InboundSkill { get; set; } // inbound_skill
    public string Dnis { get; set; } // dnis
    public byte[] Logo { get; set; } // logo
    public Organization()
    {
        Active = 1;
        StateId = "NULL";
        StateName = "N''";
        NursingNote = 0;
        UpdatedAt = DateTime.Now;
        OfficeBackline = "NULL";
        Pharmacy = "NULL";
        PharmacyPhone = "NULL";
        PharmacyBin = "NULL";
        PharmacyGroup = "NULL";
        Dme = "NULL";
        DmePhone = "NULL";
        LanguageLine = "NULL";
        LanguageLinePin = "NULL";
        Skillname = "NULL";
        OutboundSkill = "NULL";
        InboundSkill = "NULL";
        Dnis = "NULL";
    }
}

以下是配置：

// organizations
internal partial class OrganizationConfiguration : EntityTypeConfiguration<Organization>
{
    public OrganizationConfiguration()
    {
        ToTable("dbo.organizations");
        HasKey(x => x.Id);

    }
}

和数据上下文类

public partial class DataContext : DbContext, IDataContext
{
    public override int SaveChanges()
    {
        var changedEntities = ChangeTracker.Entries();
        foreach (var changedEntity in changedEntities)
        {
            if (changedEntity.Entity is BaseEntity)
            {
                var entity = (BaseEntity)changedEntity.Entity;
                switch (changedEntity.State)
                {
                    case EntityState.Added:
                        entity.OnBeforeInsert();
                        break;
                    case EntityState.Modified:
                        entity.OnBeforeUpdate();
                        break;
                    case EntityState.Deleted:
                        entity.OnBeforeDelete();
                        break;
                }
            }
        }
        var results = base.SaveChanges();
        return results;
    }
}
