各种驱动的连接方法：
1. MySQL(http://www.mysql.com) mysql-connector-java-2.0.14-bin.jar ;
Class.forName( "org.gjt.mm.mysql.Driver" );
cn = DriverManager.getConnection( "jdbc:mysql://MyDbComputerNameOrIP:3306/myDatabaseName", sUsr, sPwd );

2. PostgreSQL(http://www.de.postgresql.org) pgjdbc2.jar ;
Class.forName( "org.postgresql.Driver" );
cn = DriverManager.getConnection( "jdbc:postgresql://MyDbComputerNameOrIP/myDatabaseName", sUsr, sPwd );

3. Oracle(http://www.oracle.com/ip/deploy/database/oracle9i/) classes12.zip ;
Class.forName( "oracle.jdbc.driver.OracleDriver" );
cn = DriverManager.getConnection( "jdbc:oracle:thin:MyDbComputerNameOrIP:1521:ORCL", sUsr, sPwd );

4. Sybase(http://jtds.sourceforge.net) jconn2.jar ;
Class.forName( "com.sybase.jdbc2.jdbc.SybDriver" );
cn = DriverManager.getConnection( "jdbc:sybase:Tds:MyDbComputerNameOrIP:2638", sUsr, sPwd );
//(Default-Username/Password: "dba"/"sql")

5. Microsoft SQLServer(http://jtds.sourceforge.net) ;
Class.forName( "net.sourceforge.jtds.jdbc.Driver" );
cn = DriverManager.getConnection( "jdbc:jtds:sqlserver://MyDbComputerNameOrIP:1433/master", sUsr, sPwd );

6. Microsoft SQLServer(http://www.microsoft.com) ;
Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver" );
cn = DriverManager.getConnection( "jdbc:microsoft:sqlserver://MyDbComputerNameOrIP:1433;databaseName=master", sUsr, sPwd );

7. ODBC
Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver" );
Connection cn = DriverManager.getConnection( "jdbc:dbc:" + sDsn, sUsr, sPwd );

8.DB2 Class.forName("com.ibm.db2.jdbc.net.DB2Driver");
String url="jdbc:db2://192.9.200.108:6789/SAMPLE"
cn = DriverManager.getConnection( url, sUsr, sPwd );

9.access由于access并不是作为一项服务运行，所以url的方法对他不适用。access可以通过odbc，也可以通过服务器映射路径的形式 找到.mdb文件,参见http://rmijdbc.objectweb.org/Access/access.html 一、连接各种数据库方式速查表

　　下面罗列了各种数据库使用JDBC连接的方式，可以作为一个手册使用。

　　1、Oracle8/8i/9i数据库（thin模式）

Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
String url="jdbc:oracle:thin:@localhost:1521:orcl"; //orcl为数据库的SID
String user="test";
String password="test";
Connection conn= DriverManager.getConnection(url,user,password);

　　2、DB2数据库

Class.forName("com.ibm.db2.jdbc.app.DB2Driver ").newInstance();
String url="jdbc:db2://localhost:5000/sample"; //sample为你的数据库名
String user="admin";
String password="";
Connection conn= DriverManager.getConnection(url,user,password);

　　3、Sql Server7.0/2000数据库

Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=mydb";
//mydb为数据库
String user="sa";
String password="";
Connection conn= DriverManager.getConnection(url,user,password);

　　4、Sybase数据库

Class.forName("com.sybase.jdbc.SybDriver").newInstance();
String url =" jdbc:sybase:Tds:localhost:5007/myDB";//myDB为你的数据库名
Properties sysProps = System.getProperties();
SysProps.put("user","userid");
SysProps.put("password","user_password");
Connection conn= DriverManager.getConnection(url, SysProps);

　　5、Informix数据库

Class.forName("com.informix.jdbc.IfxDriver").newInstance();
String url = "jdbc:informix-sqli://123.45.67.89:1533/myDB:INFORMIXSERVER=myserver;
user=testuser;password=testpassword"; //myDB为数据库名
Connection conn= DriverManager.getConnection(url);

　　6、MySQL数据库

Class.forName("org.gjt.mm.mysql.Driver").newInstance();
String url ="jdbc:mysql://localhost/myDB?user=soft&password=soft1234&useUnicode=true&characterEncoding=8859_1"
//myDB为数据库名
Connection conn= DriverManager.getConnection(url);

　　7、PostgreSQL数据库

Class.forName("org.postgresql.Driver").newInstance();
String url ="jdbc:postgresql://localhost/myDB" //myDB为数据库名
String user="myuser";
String password="mypassword";
Connection conn= DriverManager.getConnection(url,user,password);

　　8、access数据库直连用ODBC的

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver") ;
String url="jdbc:odbc:Driver={MicroSoft Access Driver (*.mdb)};DBQ="+application.getRealPath("/Data/ReportDemo.mdb");
Connection conn = DriverManager.getConnection(url,"","");
Statement stmtNew=conn.createStatement() ;

　　二、JDBC连接MySql方式 （原创）

package com.test1;
import java.sql.*;

public class MySQL_test1 {

    public static void main(String[] args) {

        String DriverName="org.gjt.mm.mysql.Driver";
        String URL="jdbc:mysql://127.0.0.1:3306/test";
        String UserName="wuyun2";
        String UserPassword="1234562";

        Connection ct=null;
        PreparedStatement ps=null;
        ResultSet rs=null;

        try {
            Class.forName(DriverName);
            ct=DriverManager.getConnection(URL, UserName, UserPassword);
            System.out.println("MySQL数据库连接成功！！");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

二、JDBC连接Sql Server2000方式 （原创）

 package com.mhl.db;
 import java.sql.*;

 public class SqlHelper {

     PreparedStatement ps=null;
     Connection ct=null;
     ResultSet rs=null;
     String sqlDriver="com.microsoft.jdbc.sqlserver.SQLServerDriver";
     String url="jdbc:microsoft:sqlserver://127.0.0.1:1433;databaseName=restaurant";
     String user="wuyun";
     String passwd="wuyun";

     public SqlHelper()
     {
         try {
             Class.forName(sqlDriver);
             ct=DriverManager.getConnection(url, user, passwd);

         } catch (Exception e) {
             e.printStackTrace();
         }
     }
