这次我使用ADO.NET来插入一条数据，到数据库中。主用到存储过程。我不想每次都是用SQL文本的形式了，那样始终没有进步～～～

下面首先，我把我这次练习要用到的数据库脚本，贴出来：

USE master --使用系统数据库 GO IF EXISTS(SELECT * FROM sysdatabases WHERE name=N'DB_MyStudentLife') DROP DATABASE [DB_MyStudentLife]; --如果要创建的数据库存在的话，就删除 GO CREATE DATABASE [DB_MyStudentLife] --创建数据库 GO USE [DB_MyStudentLife] --使用数据库 GO IF EXISTS(SELECT * FROM sysobjects WHERE name=N'MyClass') DROP TABLE [MyClass] --如果要创建的数据表存在的话，就删除(注意sysobjects，一定要全部是小写的，不然有错误，不能写成大写的。) GO CREATE TABLE MyClass --创建数据表 ( C_ID INT NOT NULL PRIMARY KEY, --班级编号 C_Name NVARCHAR(200) not null, --班级名称 C_Descr nvarchar(max) not null --班级简介 ); GO IF EXISTS(SELECT * FROM sysobjects WHERE name=N'MyStudent') DROP TABLE MyStudent GO CREATE TABLE MyStudent ( S_ID int not null primary key, --学号 S_Name nvarchar(50) not null, --姓名 S_Gender char(2) not null, --性别 S_Address nvarchar(max) not null , --地址 S_Phone nvarchar(50)not null, --电话 S_Age int not null, --年龄 S_Birthday datetime not null, --生日 S_CardID int not null, --身份证号码 S_CID int not null references MyClass(C_ID) --班级编号 );

接着大家选中刚才执行脚本，创建好的数据库，然后使用我下面的数据，向数据库表里面添加数据吧

insert into MyClass(C_ID,C_Name,C_Descr)values(1,'软件1108班','武汉软件工程职业学院'); insert into MyClass(C_ID,C_Name,C_Descr)values(2,'软件1107班','武汉软件工程职业学院'); insert into MyClass(C_ID,C_Name,C_Descr)values(3,'实验班','武汉软件工程职业学院'); insert into MyStudent(S_ID,S_Name,S_Gender,S_Age,S_Birthday,S_CardID,S_Phone,S_Address,S_CID)values('1','李四','男','22','1992-09-26','111111111','11232131234',N'深圳宝安石岩',1); insert into MyStudent(S_ID,S_Name,S_Gender,S_Age,S_Birthday,S_CardID,S_Phone,S_Address,S_CID)values('2','李四','男','22','1992-09-26','111111111','11232131234',N'深圳宝安石岩',1); insert into MyStudent(S_ID,S_Name,S_Gender,S_Age,S_Birthday,S_CardID,S_Phone,S_Address,S_CID)values('3','李四','男','22','1992-09-26','111111111','11232131234',N'深圳宝安石岩',1); insert into MyStudent(S_ID,S_Name,S_Gender,S_Age,S_Birthday,S_CardID,S_Phone,S_Address,S_CID)values('4','李四','男','22','1992-09-26','111111111','11232131234',N'深圳宝安石岩',1); insert into MyStudent(S_ID,S_Name,S_Gender,S_Age,S_Birthday,S_CardID,S_Phone,S_Address,S_CID)values('5','李四','男','22','1992-09-26','111111111','11232131234',N'深圳宝安石岩',1); insert into MyStudent(S_ID,S_Name,S_Gender,S_Age,S_Birthday,S_CardID,S_Phone,S_Address,S_CID)values('6','李四','男','22','1992-09-26','111111111','11232131234',N'深圳宝安石岩',1); insert into MyStudent(S_ID,S_Name,S_Gender,S_Age,S_Birthday,S_CardID,S_Phone,S_Address,S_CID)values('7','李四','男','22','1992-09-26','111111111','11232131234',N'深圳宝安石岩',1); insert into MyStudent(S_ID,S_Name,S_Gender,S_Age,S_Birthday,S_CardID,S_Phone,S_Address,S_CID)values('8','李四','男','22','1992-09-26','111111111','11232131234',N'深圳宝安石岩',1); insert into MyStudent(S_ID,S_Name,S_Gender,S_Age,S_Birthday,S_CardID,S_Phone,S_Address,S_CID)values('9','李四','男','22','1992-09-26','111111111','11232131234',N'深圳宝安石岩',1); insert into MyStudent(S_ID,S_Name,S_Gender,S_Age,S_Birthday,S_CardID,S_Phone,S_Address,S_CID)values('10','李四','男','22','1992-09-26','111111111','11232131234',N'深圳宝安石岩',1); insert into MyStudent(S_ID,S_Name,S_Gender,S_Age,S_Birthday,S_CardID,S_Phone,S_Address,S_CID)values('11','李四','男','22','1992-09-26','111111111','11232131234',N'深圳宝安石岩',1); insert into MyStudent(S_ID,S_Name,S_Gender,S_Age,S_Birthday,S_CardID,S_Phone,S_Address,S_CID)values('12','李四','男','22','1992-09-26','111111111','11232131234',N'深圳宝安石岩',1); insert into MyStudent(S_ID,S_Name,S_Gender,S_Age,S_Birthday,S_CardID,S_Phone,S_Address,S_CID)values('13','李四','男','22','1992-09-26','111111111','11232131234',N'深圳宝安石岩',1); insert into MyStudent(S_ID,S_Name,S_Gender,S_Age,S_Birthday,S_CardID,S_Phone,S_Address,S_CID)values('14','李四','男','22','1992-09-26','111111111','11232131234',N'深圳宝安石岩',1); insert into MyStudent(S_ID,S_Name,S_Gender,S_Age,S_Birthday,S_CardID,S_Phone,S_Address,S_CID)values('15','李四','男','22','1992-09-26','111111111','11232131234',N'深圳宝安石岩',1); insert into MyStudent(S_ID,S_Name,S_Gender,S_Age,S_Birthday,S_CardID,S_Phone,S_Address,S_CID)values('16','李四','男','22','1992-09-26','111111111','11232131234',N'深圳宝安石岩',1); insert into MyStudent(S_ID,S_Name,S_Gender,S_Age,S_Birthday,S_CardID,S_Phone,S_Address,S_CID)values('17','李四','男','22','1992-09-26','111111111','11232131234',N'深圳宝安石岩',1);

说明一下，等会我要向MyClass表中插入数据，现在为这个表创建一个插入的存储过程：

IF OBJECT_ID('Ins_ClasseD','P') IS NOT NULL DROP PROCEDURE Ins_ClasseD GO CREATE PROCEDURE Ins_ClasseD @C_ID int , @C_Name nvarchar(200) , @C_Descr nvarchar(max) AS INSERT INTO dbo.MyClass ( C_ID, C_Name, C_Descr ) VALUES ( @C_ID, -- C_ID - int @C_Name, -- C_Name - nvarchar(200) @C_Descr -- C_Descr - nvarchar(max) ); GO

下面开始程序实现：

我是复习，ADO.NET，现在就随便建了一个控制台的应用程序，来开始我的测试：

注意;在下面的例子中，为了尽可能简单易于理解，我没有把连接字符串的那部分代码，放到配置文件中。

如果要放的话，要用到System.Configuration命名空间，还有一个ConfigurationManager类..具体的细节就不说了。

请看具体实现代码：

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Data; using System.Data.SqlClient; namespace ADO.NET插入一条数据到数据库中 { class Program { //连接字符串 private static string sqlCon = "server=.;database=DB_MyStudentLife;uid=sa;pwd=Password_1"; static void Main(string[] args) { //1创建连接对象（连接字符串） SqlConnection scon = new SqlConnection(sqlCon); //2创建命令对象（为命令对象设置属性） SqlCommand scmd = new SqlCommand(); scmd.CommandText = "Ins_ClasseD"; scmd.CommandType = CommandType.StoredProcedure; //这里我使用存储过程来插入数据 scmd.Connection = scon; //3打开数据库连接 scon.Open(); //设置参数 scmd.Parameters.Add(new SqlParameter("@C_ID",6)); scmd.Parameters.Add(new SqlParameter("@C_Name", "测试班")); scmd.Parameters.Add(new SqlParameter("@C_Descr", "软件测试技术")); //4发送命令 int result= scmd.ExecuteNonQuery(); //5处理数据 if (result > 0) { Console.WriteLine("插入数据成功"); } else { Console.WriteLine("插入数据失败"); } //6最后一步，差点忘记了，一定要关闭连接 scon.Close(); Console.ReadKey(); } } }

程序执行玩之后的效果图：
