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必須指寫over (order by **)，有時我根本就不想排序，想按原始順序（排序也是要時間的嘛）
--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
