( 一 ) 下载 Microsoft SQL Server 2000 Service Pack 3a 并安装

( 二 ) 下载并安装 SQL SERVER 2000 得 JDBC 驱动 ( SQL Server 2000 Driver for JDBC Service Pack 3 )

( 三 ) 配置 JDBC 驱动 classpath 环境变量 :

方法 1:

 

填加 :

C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\msbase.jar;

C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\mssqlserver.jar;

C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\msutil.jar;

 

注 : C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\ 为我 JDBC 得安装路径

 

方法 2:

 

将 mssqlserver.jar; msutil.jar; msbase.jar 拷贝到 JDK 得 lib 目录下 , 然后设置 classpath

 

D:\Java\jdk1.5.0_05\lib\sqlserver\msutil.jar;

D:\Java\jdk1.5.0_05\lib\sqlserver\msbase.jar;

D:\Java\jdk1.5.0_05\lib\sqlserver\mssqlserver.jar;

 

( 四 ) 创建连接数据库默认实例得连接代码 :

 

import java.sql.*;

public class ConSqlserver {

    

     Connection con=null;

     //Statement st=null;

     //ResultSet re=null;

    

     public ConSqlserver()

     {

            try

            {

                String driver="com.microsoft.jdbc.sqlserver.SqlServerDriver";

                String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=Northwind";

                Class.forName(driver).newInstance();

                con =DriverManager.getConnection(url,"sa","zhaopf");

                System.out.println(" 连接成功 !");

                con.close();

           

            }

            catch(Exception e)

            {

                   e.printStackTrace();

            }

           

           

     }

 

       public static void main(String[] args)

     {

            // TODO 自动生成方法存根

            ConSqlserver con=new ConSqlserver();

           

 

     }

 

}

 

( 五 ) 创建连接数据库命名实例的连接代码 ( 实例名为 SINOIT\SINOSERVER) L

 

import java.sql.*;

public class ConSqlserverppp {

    

     Connection con=null;

     //Statement st=null;

     //ResultSet re=null;

    

     public ConSqlserverppp()

     {

            try

            {

                //String driver="com.microsoft.jdbc.sqlserver.SqlServerDriver";

                String url="jdbc:microsoft:sqlserver://SINOIT\\SINOSERVER;DatabaseName=Northwind";

               

                Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();

                  

                //Class.forName(driver);//.newInstance();

                con =DriverManager.getConnection(url,"sa","zse");

                //st=con.createStatement();

                System.out.println(" 连接成功 !");

                con.close();

           

            }

            catch(Exception e)

            {

                   e.printStackTrace();

            }

           

           

     }

 

     public static void main(String[] args)

     {

           

            ConSqlserverppp con=new ConSqlserverppp();

     }

 

}
