使用CodeSmith编写ADO.Net三层

说明

自本文发布日起，发现和完善了编写的CodeSmith几处代码。

故，不再直接在文章添加代码，最新代码参见GitHub

测试数据表

--1、Books表

CREATE TABLE [dbo].[Books](
    [ID] [varchar](50) NOT NULL,
    [OrgNo] [varchar](10) NOT NULL,
    [Name] [varchar](50) NULL,
    [Num] [int] NULL,
    [InDate] [datetime] NULL,
 CONSTRAINT [PK_Books] PRIMARY KEY CLUSTERED
(
    [ID] ASC,
    [OrgNo] 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

--2、Books数据

Insert Into [Books] ([ID],[OrgNo],[Name],[Num],[InDate]) Values('1','8002','Mary','4','2017-12-04 09:29:05')

    [OrgNo] [varchar](5) NOT NULL,
    [LName] [nvarchar](100) NOT NULL
 CONSTRAINT [PK_Organization] PRIMARY KEY CLUSTERED
(
    [OrgNo] 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

--4、Organization数据
