• 分页存储过程


    /*
      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
