一、jsp連接Oracle8/8i/9i數據庫（用thin模式）
testoracle.jsp如下：
<%@ page contentType="text/html;charset=gb2312"%>

<html>
<body>
<%Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
String url="jdbc:oracle:thin:@localhost:1521:orcl";
//orcl爲你的數據庫的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()) {%>
您的第一個字段內容爲：<%=rs.getString(1)%>
您的第二個字段內容爲：<%=rs.getString(2)%>
<%}%>
<%out.print("數據庫操作成功，恭喜你");%>
<%rs.close();
stmt.close();
conn.close();
%>
</body>
</html>
二、jsp連接Sql Server7.0/2000數據庫
