Entity Framework 6.x 学习之Database First

一、单表操作

　　

　　1. 建表

CREATE TABLE [Chapter1].[Customer]
(
[CustomerId] [int] NOT NULL IDENTITY(1, 1),
[Name] [varchar] (50) COLLATE Chinese_PRC_CI_AS NOT NULL,
[Email] [varchar] (1024) COLLATE Chinese_PRC_CI_AS NOT NULL,
[Phone] [varchar] (50) COLLATE Chinese_PRC_CI_AS NOT NULL
) ON [PRIMARY]
GO
ALTER TABLE [Chapter1].[Customer] ADD CONSTRAINT [PK_Customer_10] PRIMARY KEY CLUSTERED  ([CustomerId]) ON [PRIMARY]
GO

2. 创建控制台应用程序 Ex01 ，解决方案名称 EF6xDemo
     3. 建立模型

namespace Ex01
{
    using System;
    using System.Collections.Generic;

    public partial class Customer
    {
        public int CustomerId { get; set; }
        public string Name { get; set; }
        public string Email { get; set; }
        public string Phone { get; set; }
    }
}

Customer.cs

namespace Ex01
{
    using System;
    using System.Data.Entity;
    using System.Data.Entity.Infrastructure;

    public partial class EFRecipesEntities : DbContext
    {
        public EFRecipesEntities()
            : base("name=EFRecipesEntities")
        {
        }

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            throw new UnintentionalCodeFirstException();
        }

        public virtual DbSet<Customer> Customers { get; set; }
    }
}

EF6RecipesContext.Context.cs

二、主从表操作，and 在数据库里没有建立关系的主从表又该怎么操作？
