1、Oracle8/8i/9i數據庫(thin模式)
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
String url="jdbc:oracle:thin:@localhost:1521:orcl";
//orcl為數據庫的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");
//查詢
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"); //刪
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表示第一個?號，插入值為4
pstm.setString(2,"小陳");//2表示第二個?號，插入值為"小陳"
pstm.executeUpdate();//真正插入數據庫
2、DB2數據庫
Class.forName("com.ibm.db2.jdbc.app.DB2Driver ").newInstance();
String url="jdbc:db2://localhost:5000/sample";
//sample為你的數據庫名
String user="admin";
String password="";
Connection conn= DriverManager.getConnection(url,user,password);
3、Sql Server7.0/2000數據庫

//mydb為數據庫
String user="sa";
String password="";
Connection conn= DriverManager.getConnection(url,user,password);
4、Sybase數據庫
Class.forName("com.sybase.jdbc.SybDriver").newInstance();
