1．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);

----------Sql Server2005数据库-------------
String driverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver";  //加载JDBC驱动
  String dbURL = "jdbc:sqlserver://localhost:1433; DatabaseName=sample";  //连接服务器和数据库sample
  String userName = "sa";  //默认用户名
  String userPwd = "123456";  //密码
-----------------------------------------------------------------------------------------------------
2．Oracle8/8i/9i数据库（thin模式）
Class.forName("oracle.jdbc.driver.OracleDriver");
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);

-----------------------------------------------------------------------------------------------------
3．MySQL数据库
private static String driver="org.gjt.mm.mysql.Driver";
private static String url="jdbc:mysql://localhost/test";
private static String uid="root";
private static String pwd="";

public Connection conn=null;
public PreparedStatement pstm=null;
public ResultSet rs=null;

public Connection getConnection(){
  try {
   Class.forName(driver);
   conn=DriverManager.getConnection(url, uid, pwd);
  } catch (Exception e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }

  return conn;
}
----------------------------------------------------------------------------------------------
4．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);

--------------------------------------------  --------------------------------------------------
5．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．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);
-------------------------------------------------------------------------------------------------
7．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() ;
