背景

使用 ef4.1 的代码优先模型。数据库是 Oracle，所以我们也在使用 Devart dotConnect。

问题

将应用程序部署到服务器后，看到 sql 语句和无效列名的错误。在我的开发 PC 上一切正常。

创建了一个小型测试控制台应用程序并复制了该行为。在我的电脑上，不是调试而是运行应用程序，它工作正常并正确选择数据。在服务器上，select 语句有两个额外的外键列名。

namespace Cul2.Model
{
    [Table("LAB_REQUISITION")]
    public class LabRequisition : EntityBase
    {
        public LabRequisition()
        {
            Attributes = new Collection<LabRequisitionAttribute>();
            Samples = new Collection<LabSample>();
        }

        [Key]
        [Column("REQUISITION_ID")]
        public long? RequisitionId { get; set; }

        [Column("MATERIAL_ID")]
        public long? MaterialId { get; set; }

        [Include]
        [Association("Material", "MaterialId", "MaterialId", IsForeignKey = true)]
        public virtual LabMaterial Material { get; set; }

        public int? LabNumber { get; set; }

        [Column("COLLECTOR_ID")]

        public virtual ComUser Collector { get; set; }

        [Column("RECEIVER_ID")]
        public long? ReceiverId { get; set; }

        [Include]
        [Association("Receiver", "ReceiverId", "UserId")]
        [ForeignKey("ReceiverId")]
        public virtual ComUser Receiver { get; set; }

        [Column("TEMPLATE_ID")]
        public long? TemplateId { get; set; }

        [Include]
        [Association("Template", "TemplateId", "TemplateId", IsForeignKey = true)]
        public virtual LabTemplate Template { get; set; }

        [Column("REASON_ID")]
        public long? ReasonId { get; set; }

        [Include]
        [Association("Reason", "ReasonId", "ReasonId", IsForeignKey = true)]
        public virtual LabReason Reason { get; set; }

        [Column("RECEIVED_DATE")]
        public DateTime? ReceivedDate { get; set; }

        [Include]
        [Association("Samples", "RequisitionId", "RequisitionId")]
        [ForeignKey("RequisitionId")]

        [Include]
        [Association("Attributes", "RequisitionId", "RequisitionId")]
        public ICollection<LabRequisitionAttribute> Attributes { get; set; }

        public override string ToString()
        {
            return LabNumber == null ? "New" : LabNumber.ToString();
        }
    }
}

在我的 PC 上，这是为该实体生成的模式 sql：

-- Table LAB_REQUISITION
CREATE TABLE LAB_REQUISITION ( 
  REQUISITION_ID NUMBER(18) NOT NULL,
  MATERIAL_ID NUMBER(18) NULL,
  LAB_NUMBER NUMBER(10) NULL,
  COLLECTOR_ID NUMBER(18) NULL,
  RECEIVER_ID NUMBER(18) NULL,
  COLLECTION_DATE TIMESTAMP(7) NULL,
  STATUS_ID NUMBER(18) NULL,
  IS_ACTIVE NUMBER(1) NOT NULL,
  TEMPLATE_ID NUMBER(18) NULL,
  REASON_ID NUMBER(18) NULL,
  RECEIVED_DATE TIMESTAMP(7) NULL,
  ROW_VERSION NUMBER(18,2) NULL,
  CREATED TIMESTAMP(7) NULL,
  CREATED_BY_ID NUMBER(18) NULL,
  LAST_UPDATED TIMESTAMP(7) NULL,
  LAST_UPDATED_BY_ID NUMBER(18) NULL,
  PRIMARY KEY (REQUISITION_ID)
)
/

在服务器上，这是生成的架构：

-- Table LAB_REQUISITION
CREATE TABLE LAB_REQUISITION ( 
  REQUISITION_ID NUMBER(18) NOT NULL,
  MATERIAL_ID NUMBER(18) NULL,
  LAB_NUMBER NUMBER(10) NULL,
  COLLECTOR_ID NUMBER(18) NULL,
  RECEIVER_ID NUMBER(18) NULL,
  COLLECTION_DATE TIMESTAMP(7) NULL,
  STATUS_ID NUMBER(18) NULL,
  IS_ACTIVE NUMBER(1) NOT NULL,
  TEMPLATE_ID NUMBER(18) NULL,
  REASON_ID NUMBER(18) NULL,
  RECEIVED_DATE TIMESTAMP(7) NULL,
  ROW_VERSION NUMBER(18,2) NULL,
  CREATED TIMESTAMP(7) NULL,
  CREATED_BY_ID NUMBER(18) NULL,
  LAST_UPDATED TIMESTAMP(7) NULL,
  LAST_UPDATED_BY_ID NUMBER(18) NULL,
  "Collector_UserId" NUMBER(18) NULL,
  "Receiver_UserId" NUMBER(18) NULL,
  PRIMARY KEY (REQUISITION_ID)
)
/

Collector_UserId和Receiver_UserId列不正确，它们导致 SQL 选择错误。

  • 我无法弄清楚为什么该模型会在我的 Dev PC 上生成正确的 SQL，但在服务器上它会生成虚假的额外列。

  • 该应用程序在 Dev PC 和服务器上完全相同，除了在服务器上我必须将 DbProviderFactories 部分添加到 app.config 中——在我的 PC 上，我猜因为安装了 Devart，它已经注册。否则完全一样。

  • 在我的 Dev PC 上，Devart 库是从 GAC 加载的，而在服务器上，它们是从 bin 文件夹加载的。据我所知，版本是相同的。
