实体如下：
// tbl_TimeOffRequests
public partial class TimeOffRequest
{
public int TimeOffRequestID { get; set; } // fldTimeOffRequestID (Primary key)
public string CorpCode { get; set; } // fldCorpCode (length: 10)
public int RestaurantNumber { get; set; } // fldRestaurantNumber
public int EmpID { get; set; } // fldEmpID
public string SAM { get; set; } // fldSAM (length: 25)
public System.DateTime RequestDateStart { get; set; } // fldRequestDateStart
public System.DateTime RequestDateEnd { get; set; } // fldRequestDateEnd
public byte Status { get; set; } // fldStatus
public System.DateTime EntryDate { get; set; } // fldEntryDate
public System.DateTime UserUpdateDate { get; set; } // fldUserUpdateDate
public string ManagerComment { get; set; } // fldManagerComment (length: 255)

public string ManagersLogonID { get; set; } // fldManagersLogonID (length: 30)
public System.DateTime? MgrModifiedDate { get; set; } // fldMgrModifiedDate
public string MgrModifiedBy { get; set; } // fldMgrModifiedBy (length: 55)
public string fName { get; set; } // fldfName (length: 30)
public string lName { get; set; } // fldlName (length: 25)
public string PJobCode { get; set; } // fldPJobCode (length: 4)
public byte? JobLoc { get; set; } // fldJobLoc
public int? PeoplesoftID { get; set; } // fldPeoplesoftID
public System.Guid? SeriesID { get; set; } // fldSeriesID
public bool TempScheduleChange { get; set; } = false; // fldTempScheduleChange
}
该实体的上下文条目是：

所有列名称均与数据库中的名称相匹配。是否有什么东西搭错了脚手架？
编辑 这是表的 DDL
CREATE TABLE [dbo].[tbl_TimeOffRequests](
[fldTimeOffRequestID] [int] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL,
[fldCorpCode] [varchar](10) NOT NULL,
[fldRestaurantNumber] [int] NOT NULL,
[fldEmpID] [int] NOT NULL,
[fldSAM] [varchar](25) NULL,

)WITH (PAD_INDEX = ON, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 80) ON [PRIMARY]
) ON [PRIMARY]
GO
ALTER TABLE [dbo].[tbl_TimeOffRequests] ADD CONSTRAINT [DF_tbl_TimeOffRequests_fldTempScheduleChange] DEFAULT ((0)) FOR [fldTempScheduleChange]
GO
这是 EntityFrameworkCore 生成的 SQL：
SELECT TOP(1) [t].[fldTimeOffRequestID], [t].[fldCorpCode], [t].[fldEmpID], [t].[fldEmployeeComment], [t].[fldEntryDate], [t].[fldJobLoc], [t].[fldManagerComment], [t].[fldManagersLogonID], [t].[fldMgrModifiedBy], [t].[fldMgrModifiedDate], [t].[fldPJobCode], [t].[fldPeoplesoftID], [t].[fldRequestDateEnd], [t].[fldRequestDateStart], [t].[fldRestaurantNumber], [t].[fldSAM], [t].[fldSeriesID], [t].[fldStatus], [t].[fldTempScheduleChange], [t].[fldUserUpdateDate], [t].[fldfName], [t].[fldlName]
FROM [TimeOffRequest] AS [t]
ORDER BY [t].[fldEntryDate] DESC
看起来它从表名中删除了“tbl_”前缀。我该如何防止这种情况发生？
问题是数据库中有两个表名称相似……
EF Core 将它们映射到同一个实体：TimeOffRequest。显然这是一个古怪的数据结构，因此 EF Core 团队可能没有考虑到这种情况。
从 PackageManagerConsole 检查更新数据库，并查看表与其类实体是否匹配。
