ORA-01400: 无法将 NULL 插入 ("TBLS"."FTP_GET_TESTING"."FTP_LOOKUP_ID")，但据我所知它不是 null

Question

我不知道是什么问题。我正在使用 Entity Framework 6 访问 Oracle 12c 数据库。当我尝试向 table 添加新行时，我的标题中出现了 ORA-01400 错误。但是，当我查看我试图在调试器中添加的值时，它们不为空。

 protected void InsertButton_Click(object sender, EventArgs e)
{           
     AddNewPartner(GetFields());            
}

 public void AddNewPartner(FTP_GET_TESTING ftpPartner)
{               
    using (Entities myEntities = new Entities())
    {
            myEntities.FTP_GET_TESTING.Add(ftpPartner);
            myEntities.SaveChanges();            
    }
}

更新

这是模型（数据优先）：

public partial class FTP_GET_TESTING
{
public string FTP_LOOKUP_ID { get; set; }
public string FTP_HOST { get; set; }
public string USER_NAME { get; set; }
public string PASSWORD { get; set; }
public string ADAPTER { get; set; }
public string FTP_MODE { get; set; }
public string PICKUP_FOLDER { get; set; }
public string DESTINATION_FOLDER { get; set; }
public string DELIVERY_FILENAME { get; set; }
public string DESTINATION_BP { get; set; }
public string ARCHIVE_FOLDER { get; set; }
public string REMOTE_ARCHIVE_FILE_EXTENSION { get; set; }
public string REMOTE_ARCHIVE_DIRECTORY { get; set; }
public string REMOTE_FILE_DELETE { get; set; }
public string FTP_DOWN { get; set; }

public string SFTP_COMPRESSION { get; set; }
public string SFTP_KNOWNHOST_KEY_ID { get; set; }
public string SFTP_PREF_AUTH_METHOD { get; set; }
public string SFTP_PREFERRED_CIPHER { get; set; }
public string SFTP_PREFERRED_MAC { get; set; }
public string SFTP_USER_ID_KEY_ID { get; set; }
public string FMC_RELATIONSHIP_NAME { get; set; }
public string USER_FIELD1 { get; set; }
public string USER_FIELD2 { get; set; }
public string USER_FIELD3 { get; set; }
public string NOTES { get; set; }
public Nullable<System.DateTime> LAST_UPDATE { get; set; }
public string LAST_USER_UPDATE { get; set; }
public string PARTNER_NAME { get; set; }
public string MAILBOX_ID { get; set; }
public string REMEDY_QUEUE { get; set; }
public string SCHEDULE { get; set; }
public Nullable<decimal> ALERT_FREQUENCY { get; set; }
public string PRIORITY { get; set; }
public string CONTACT_NAME { get; set; }
public string CONTACT_EMAIL { get; set; }
public string CONTACT_PHONE { get; set; }
public string FTP_SEND_LOOKUP_ID { get; set; }
}

我在调试器中使用立即数 window 验证添加的数据。

myEntities.FTP_GET_TESTING.Add(ftpGet);
   {GP_GENERIC_FTP_GET_TESTING}
   ADAPTER: "FTP_Client_Adapter_Group"
   ALERT_FREQUENCY: 120

我认为这就是您想要查看的配置信息。

<configSections>
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
<section name="oracle.manageddataaccess.client" type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess, Version=4.121.2.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />

我还需要在此处添加什么以帮助找出问题？

Answer 1

为了解决这个问题，我做了两件事。首先我删除了模型 FTP_GET_TESTING 然后我将测试 table 中的主键（FTP_LOOKUP_ID）与非测试 table 中的 PK 进行了比较，并且存在一些差异。在 table FTP_GET_TESTING 的设计视图中，我的 PK 约束被命名为 SYS_C0027857 我将其更改为 FTP_GET_TESTING_PK。我还更改了索引的名称以匹配约束名称 FTP_GET_TESTING_PK。然后我将 table 添加回我的模型并且它运行良好。

我不确定更改约束和索引中的 PK 名称是否解决了问题，或者只是删除并 re-adding 是否成功。

如果有人愿意为未来的观众添加一些意见，以便我能更多地了解发生了什么，我将不胜感激。
