分頁表並獲取行數

Question

下面的查詢從表中獲取行的子集，該表從第10行開始，到第20行結束。此外，要保存查詢，我需要返回表中的總行數。 這是我能想到的最佳解決方案。 有沒有更有效/更優雅的方法？ 特別地，我不喜歡partition by 1部分partition by 1 。

select *
from (select count(*) over (partition by 1) as [count],
             row_number() over (order by [Name],[Description]) as [row],
             *
      from [Products]) as t
where row between 10 and 20

Answer 1

如果您不喜歡，請將其刪除！

select *
from (select count(*) over () as [count],
             row_number() over (order by [Name],[Description]) as [row],
             *
      from [Products]) as t
where row between 10 and 20

但是，除此之外，查詢並不是最佳的。 您應該以傳統方式進行計數。

select *
from (select count(*) as [count]
        from [Products]) X
cross join (
    select row_number() over (order by [Name],[Description]) as [row],
           *
      from [Products]) as t
where row between 10 and 20

您可以將它們放在一起並按Ctrl-M，然后執行。 計划看起來會完全不同。
