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：
以上所述就是本文的全部内容了，希望大家能够喜欢。
