淺談ADO.NET數(shù)據(jù)庫(kù)腳本

這次我使用ADO.NET來(lái)插入一條數(shù)據(jù)，到數(shù)據(jù)庫(kù)中。主用到存儲(chǔ)過(guò)程。我不想每次都是用SQL文本的形式了，那樣始終沒(méi)有進(jìn)步～～～

下面首先，我把我這次練習(xí)要用到的數(shù)據(jù)庫(kù)腳本，貼出來(lái)：

 USE master --使用系統(tǒng)數(shù)據(jù)庫(kù)
 GO
 IF EXISTS(SELECT * FROM sysdatabases WHERE name=N'DB_MyStudentLife') 
 DROP DATABASE [DB_MyStudentLife]; --如果要?jiǎng)?chuàng)建的數(shù)據(jù)庫(kù)存在的話，就刪除
 GO
 CREATE DATABASE [DB_MyStudentLife] --創(chuàng)建數(shù)據(jù)庫(kù)
 GO
 USE [DB_MyStudentLife]  --使用數(shù)據(jù)庫(kù)
 GO
 IF EXISTS(SELECT * FROM sysobjects WHERE name=N'MyClass')
 DROP TABLE [MyClass]   --如果要?jiǎng)?chuàng)建的數(shù)據(jù)表存在的話，就刪除(注意sysobjects，一定要全部是小寫(xiě)的，不然有錯(cuò)誤，不能寫(xiě)成大寫(xiě)的。)
 GO
 CREATE TABLE MyClass        --創(chuàng)建數(shù)據(jù)表
 (
  C_ID INT NOT NULL PRIMARY KEY,    --班級(jí)編號(hào)
  C_Name NVARCHAR(200) not null,    --班級(jí)名稱
  C_Descr nvarchar(max) not null    --班級(jí)簡(jiǎn)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, --學(xué)號(hào)
 S_Name nvarchar(50) not null,     --姓名
 S_Gender char(2) not null,      --性別
 S_Address nvarchar(max) not null ,    --地址
 S_Phone nvarchar(50)not null,     --電話
 S_Age int not null,       --年齡
 S_Birthday datetime not null,     --生日
 S_CardID int not null,       --身份證號(hào)碼
 S_CID int not null references MyClass(C_ID) --班級(jí)編號(hào)
 
 );

接著大家選中剛才執(zhí)行腳本，創(chuàng)建好的數(shù)據(jù)庫(kù)，然后使用我下面的數(shù)據(jù)，向數(shù)據(jù)庫(kù)表里面添加數(shù)據(jù)吧

 insert into MyClass(C_ID,C_Name,C_Descr)values(1,'軟件1108班','武漢軟件工程職業(yè)學(xué)院');

說(shuō)明一下，等會(huì)我要向MyClass表中插入數(shù)據(jù)，現(xiàn)在為這個(gè)表創(chuàng)建一個(gè)插入的存儲(chǔ)過(guò)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

下面開(kāi)始程序?qū)崿F(xiàn)：

我是復(fù)習(xí)，ADO.NET，現(xiàn)在就隨便建了一個(gè)控制臺(tái)的應(yīng)用程序，來(lái)開(kāi)始我的測(cè)試：

注意;在下面的例子中，為了盡可能簡(jiǎn)單易于理解，我沒(méi)有把連接字符串的那部分代碼，放到配置文件中。

如果要放的話，要用到System.Configuration命名空間，還有一個(gè)ConfigurationManager類..具體的細(xì)節(jié)就不說(shuō)了。

請(qǐng)看具體實(shí)現(xiàn)代碼：

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插入一條數(shù)據(jù)到數(shù)據(jù)庫(kù)中
{
 class Program
 {
  //連接字符串
  private static string sqlCon = "server=.;database=DB_MyStudentLife;uid=sa;pwd=Password_1";
  static void Main(string[] args)
  {
   //1創(chuàng)建連接對(duì)象（連接字符串）
   SqlConnection scon = new SqlConnection(sqlCon);
   
   //2創(chuàng)建命令對(duì)象（為命令對(duì)象設(shè)置屬性）
   SqlCommand scmd = new SqlCommand();
   scmd.CommandText = "Ins_ClasseD";
   scmd.CommandType = CommandType.StoredProcedure; //這里我使用存儲(chǔ)過(guò)程來(lái)插入數(shù)據(jù)
   scmd.Connection = scon;

   //3打開(kāi)數(shù)據(jù)庫(kù)連接
   scon.Open();
   

   //設(shè)置參數(shù)
   scmd.Parameters.Add(new SqlParameter("@C_ID",6));
   scmd.Parameters.Add(new SqlParameter("@C_Name", "測(cè)試班"));
   scmd.Parameters.Add(new SqlParameter("@C_Descr", "軟件測(cè)試技術(shù)"));
   //4發(fā)送命令
   int result= scmd.ExecuteNonQuery();

   //5處理數(shù)據(jù)
   if (result > 0)
   {
    Console.WriteLine("插入數(shù)據(jù)成功");
   }
   else
   {
    Console.WriteLine("插入數(shù)據(jù)失敗");
   }
   //6最后一步，差點(diǎn)忘記了，一定要關(guān)閉連接
   scon.Close();

   Console.ReadKey();
 
  }
 }
}

程序執(zhí)行玩之后的效果圖：
