纯JSP分页代码之sqlserver2005/2008
昨天看到一篇《 纯JSP分页代码 》的文章,是用于mysql,稍微修改下,用于Sqlserver2005/2008,没有异常处理。没有考虑性能等。 现将代码贴出,以供初学者参考: 注:邀月使用环境Eclipse 3.4.2+Tomcat 6.18+Sqlserver2005 sp3调试成功。 页面pagelistDemo.js
昨天看到一篇《纯JSP分页代码》的文章,是用于mysql,稍微修改下,用于Sqlserver2005/2008,没有异常处理。没有考虑性能等。
现将代码贴出,以供初学者参考:
注:邀月使用环境Eclipse 3.4.2+Tomcat 6.18+Sqlserver2005 sp3调试成功。
页面pagelistDemo.jsp内容:

String url = "jdbc:sqlserver://" + Globals.Server
+ ";databaseName=" + Globals.DbName;

Globals.username, Globals.pwd);
Statement statement = connection.createStatement();
//每页显示记录数
int PageSize = 10;
int StartRow = 0; //开始显示记录的编号
int PageNo = 0;//需要显示的页数
int CounterStart = 0;//每页页码的初始值
int CounterEnd = 0;//显示页码的最大值
int RecordCount = 0;//总记录数;
int MaxPage = 0;//总页数
int PrevStart = 0;//前一页
int NextPage = 0;//
int LastRec = 0;
int LastStartRecord = 0;//最后一页开始显示记录的编号
//获取需要显示的页数,由用户提交
if (request.getParameter("PageNo") == null) { //如果为空,则表示第1页
if (StartRow == 0) {
PageNo = StartRow + 1; //设定为1
}
} else {
PageNo = Integer.parseInt(request.getParameter("PageNo")); //获得用户提交的页数
StartRow = (PageNo - 1) * PageSize; //获得开始显示的记录编号
}
//因为显示页码的数量是动态变化的,假如总共有一百页,则不可能同时显示100个链接。而是根据当前的页数显示
//一定数量的页面链接
//设置显示页码的初始值!!
if (PageNo % PageSize == 0) {
CounterStart = PageNo - (PageSize - 1);
} else {
CounterStart = PageNo - (PageNo % PageSize) + 1;
}
