这是人家的一段代码:
JSP实现树型组织架构
//orgView.jsp

<%@ page contentType="text/html;charset=Big5"%>
<%@ include file="orgConnInclude.jsp"%>

<%
request.setCharacterEncoding("big5");
PreparedStatement ps=null;
ResultSet rs=null;

String queryCount=" select count(*) "+
" from ngb_org "+
" where total like ? ORDER BY TOTAL ";

String queryName=" select * "+
" from ngb_org "+
" where total like ? ORDER BY TOTAL ";

%>
