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);
//小例子
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
String url="jdbc:oracle:thin:@localhost:1521:orcl";
conn= DriverManager.getConnection(url,"commerce","password");
//查询
rs = stm.executeQuery("select id,name from T1");
while(rs.next())
{
System.out.println("id:"+rs.getString(1));
System.out.println("name:"+rs.getString(2));
}
stm.execute("inset into T1(id,name) values(1,"dd")"); //增
stm.executeUpdate("delete from T1 where id = 2"); //删
stm.executeUpdate("update T1 set name = 'bb' where id = 3");//改
//PreparedStatement用法
PreparedStatement pstm = null;
pstm.conn.prepareStatement("insert into T1(id,name) values(?,?)");
pstm.setInt(1,4);//1表示第一个?号，插入值为4
pstm.setString(2,"小陈");//2表示第二个?号，插入值为"小陈"
pstm.executeUpdate();//真正插入数据库
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();

user=testuser;password=testpassword";
//myDB为数据库名
Connection conn= DriverManager.getConnection(url);
6、mysql数据库

String url ="jdbc:mysql://localhost/myDB?user=soft&password=soft1234&useUnicod
e=true&characterEncoding=8859_1"
//myDB为数据库名
Connection conn= DriverManager.getConnection(url);
7、PostgreSQL数据库
