jsp oracle分页与sqlserver分页

博客分类：

java

先来个sqlserver分页
数据库很简单就一张表
表字段有：
id，主键，自动增长
name 组名

直接贴代码;

<%@ page language="java" import="java.sql.*,java.util.*" pageEncoding="gbk"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
String pageNowStr=request.getParameter("pageNow");       //当前是第几页
int pageNow=1;
if(pageNowStr!=null){
  pageNow=Integer.valueOf(pageNowStr);
}
%>

            if(pageNow!=1){     
              out.print("<a href=sqlserver.jsp?pageNow="+(pageNow-1)+">上一页</a>&nbsp;&nbsp;&nbsp;");
              }
            for(int i=pageNow;i<pageNow+3;i++){  
              if(i<=pageCount)      //使其不超过总页数
               out.print("<a href=sqlserver.jsp?pageNow="+i+">"+i+"</a>&nbsp;&nbsp;&nbsp;");
      
            }  
             if(pageNow<pageCount)  
             out.print("<a href=sqlserver.jsp?pageNow="+(pageNow+1)+">下一页</a>");
           %>

  </body>

效果如下;
