概要 本文介绍如何使用 Microsoft SQL Server 2000 JDBC 驱动程序连接到 SQL Server 2000。注意：有关 Microsoft...

设置 CLASSPATH 变量

• /Your installation path/Lib/Msbase.jar
• /Your installation path/Lib/Msutil.jar
• /Your installation path/Lib/Mssqlserver.jar

注册驱动程序

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

传递连接 URL

con = DriverManager.getConnection("jdbc:microsoft:sqlserver://localhost:1433","userName","password");

用于测试连接的代码示例

import java.*;
public class Connect{
     private java.sql.Connection  con = null;
     private final String url = "jdbc:microsoft:sqlserver://";
     private final String serverName= "localhost";
     private final String portNumber = "1433";
     private final String databaseName= "pubs";
     private final String userName = "user";
     private final String password = "password";
     // Informs the driver to use server a side-cursor,
     // which permits more than one active statement 
     // on a connection.
     private final String selectMethod = "cursor"; 

     // Constructor
     public Connect(){}

     private String getConnectionUrl(){
          return url+serverName+":"+portNumber+";databaseName="+databaseName+";selectMethod="+selectMethod+";";
     }

     private java.sql.Connection getConnection(){
          try{
               Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver"); 
               con = java.sql.DriverManager.getConnection(getConnectionUrl(),userName,password);
               if(con!=null) System.out.println("Connection Successful!");
          }catch(Exception e){
               e.printStackTrace();
               System.out.println("Error Trace in getConnection() : " + e.getMessage());
         }
          return con;
      }

     /*
          Display the driver properties,database details 
     */ 

     public void displayDbProperties(){
          java.sql.DatabaseMetaData dm = null;
          java.sql.ResultSet rs = null;
          try{
               con= this.getConnection();
               if(con!=null){
                    dm = con.getMetaData();
                    System.out.println("Driver Information");
                    System.out.println("/tDriver Name: "+ dm.getDriverName());
                    System.out.println("/tDriver Version: "+ dm.getDriverVersion ());
                    System.out.println("/nDatabase Information ");
                    System.out.println("/tDatabase Name: "+ dm.getDatabaseProductName());
                    System.out.println("/tDatabase Version: "+ dm.getDatabaseProductVersion());
                    System.out.println("Avalilable Catalogs ");
                    rs = dm.getCatalogs();
                    while(rs.next()){
                         System.out.println("/tcatalog: "+ rs.getString(1));
                    } 
                    rs.close();
                    rs = null;
                    closeConnection();
               }else System.out.println("Error: No active Connection");
          }catch(Exception e){
               e.printStackTrace();
          }
          dm=null;
     }     

     private void closeConnection(){
          try{
               if(con!=null)
                    con.close();
               con=null;
          }catch(Exception e){
               e.printStackTrace();
          }
     }
     public static void main(String[] args) throws Exception
       {
          Connect myDbTest = new Connect();
          myDbTest.displayDbProperties();
       }
}

Connection Successful!
