主要数据库的关键代码,其他访问数据库代码省略
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();

8,SQLSERVER2005
String driverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver"; //加载JDBC驱动
String dbURL = "jdbc:sqlserver://localhost:1433;DatabaseName=pubs"; //连接服务器和数据库sample
String userName = "sa"; //默认用户名
