表:
CREATE TABLE [dbo].[Test]( [PKID] [uniqueidentifier] NOT NULL, [Name] [nvarchar](50) NULL, [AA] [nchar](10) NULL, [BB] [nchar](10) NULL, [CC] [nchar](10) NULL, [DD] [nchar](10) NULL, [EE] [nchar](10) NULL, [FF] [nchar](10) NULL, [TestType] [tinyint] NULL, CONSTRAINT [PK_Test] PRIMARY KEY CLUSTERED ( [PKID] ASC)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]) ON [PRIMARY]
GO
实体:
public abstract class Test : Entity { [Key] public Guid PKID { get; set; } public string Name { get; set; } }
public class A : Test { public string BB { get; set; } public string CC { get; set; } public string DD { get; set; } } public class B : Test { public string AA { get; set; } public string BB { get; set; } public string CC { get; set; } public string DD { get; set; } } public class C : Test { public string EE { get; set; } public string FF { get; set; } }
modelBuilder.Entity<Test>() .Map<A>(m => m.Requires("TestType").HasValue((byte)0)) .Map<B>(m => m.Requires("TestType").HasValue((byte)1)) .Map<C>(m => m.Requires("TestType").HasValue((byte)2));
当向A实体插入记录时,生成下面sql:
exec sp_executesql N'insert [dbo].[Test]([PKID], [Name], [BB], [CC], [DD], [AA], [BB1], [CC1], [DD1], [EE], [FF], [TestType])values (@0, @1, @2, @3, @4, null, null, null, null, null, null, @5)',N'@0 uniqueidentifier,@1 nvarchar(max) ,@2 nvarchar(max) ,@3 nvarchar(max) ,@4 nvarchar(max) ,@5 tinyint',@0='B1264CFD-8E16-451D-B015-E9CE756EC7F9',@1=N'A',@2=N'bb',@3=N'cc',@4=N'dd',@5=0
请问为何BB,CC,DD变成了BB1,CC1,DD1?
