jsp和oracle连接问题
程序代码:
<%Class.forName( "oracle.jdbc.driver.OracleDriver ").newInstance();
String url= "jdbc:oracle:thin:@192.168.1.2:1521:dingjun ";
String user= "system ";
String password= "manager ";
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);//建立可滚动的查询结果
String sql= "select * from vol1 ";
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();
%>
