设置sqlServer使用ROW_NUMBER时不排序 --1.看到NHibernate是这样写的分页,感觉写起来比较容易理解（应该不会有效率问题吧？）
--with只是定一个别名？ [sql]
with query as (select ROW_NUMBER() over(order by (select 0)) AS ROWNUM, FROM Product)
select from query where ROWNUM BETWEEN 5 AND 10 --2.ROW_NUMBER必须指写over (order by *)，有时我根本就不想排序，想按原始顺序（排序也是要时间的嘛） --方法就是:
select ROW_NUMBER() over(order by (select 0)) AS ROWNUM, FROM Product 排序 就是 :
select Row_number() over(order by Oper_Date desc) AS ROWNUM,* FROM Product
