主要是末尾的语句，拆分下来便是这样：
select top 每页数 列名 from [表名] where [排序字段名] < --1 倒序输出若列 小于之前页数的最小值
(select min ( [排序字段名] )from --2 获得一个指定列名中的最小值并输出
(select top (当前页-1)*每页数 [排序字段名] from [表名] where [条件] [排序类型]) --3 选择之前页数总数据倒序输出
as Tmep_QC)--4 建立一个名为Tmep_QC的临时表--2 获得一个指定列名中的最小值并输出
and [条件] [排序类型]--1 倒序输出若列 小于之前页数的最小值
