JSP连接Oracle8/8i/9i数据库 (用thin模式)

testoracle.jsp如下

<%@ page contentType = "text/html;charset=gb2312"%>
<%@ page import = "java.sql.*"%>
<html>
<body>
<%
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
String url = "jdbc:oracle:thin:@localhost:1521:orcl";//orcl为你的数据库的SID
String user = "scott";
String password = "tiger";
Connection conn = DriverManager.getConnection(url,user,password);
Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql = "select * from test";
ResultSet rs = stmt.executeQuery(sql);

while(rs.next()) {%>
	您的第一个字段内容为：<%=rs.getString(1)%>
	您的第二个字段内容为：<%=rs.getString(2)%>
<%}%>
	<%out.print("数据库操作成功，恭喜你");%>
<%
	rs.close();
	stmt.close();
	conn.close();
%>
</body>
</html>
