/*
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
