/*  

数据库分页存储过程，支持倒序和升序  

参数说明：  

  @tablename：为搜索表名  

  @tablefield：为表的字段，约定为表的主键,  

  @where：为搜索表名，要显示所有记录请设为"1=1"  

  @orderby：为搜索结果排序，如order by id desc  

  @fieldlist：为字段列表，如userid, username  

  @curpage：当前页码  

  @page_record：每页记录条数  

  @Sort：排序标识（如果是倒序排，参数值为desc，为升序，参数值为asc，跟orderby参数是对应的）  

结果： 返回表tablename中满足条件where的第curpage页的page_record条记录，结果按orderby排序
