Question

例如，我的表中有10.000条记录。每次执行查询时，我都会得到页码n作为参数。我必须选择从n到n*100的记录，这些记录可以满足某些复杂条件。我还使用ORDER BY，因此我无法保留最后一个元素的PrimaryKey并使用主键选择前n个记录。我怎样才能做到这一点？

Answer 1

根据页面计算，在以下查询中传递From和To参数的值。

WITH NumberedMyTable AS
(
    SELECT
        *,
        ROW_NUMBER() OVER (ORDER BY Id) AS RowNumber
    FROM
        MyTable
)
SELECT
    *
FROM
    NumberedMyTable
WHERE
    RowNumber BETWEEN @From AND @To

Answer 2

declare @n int
set @n=2

with my_query as(
    select ROW_NUMBER() over (order by name) as ID, * 
    from sys.tables
)
select * 
from my_query
where ID >=@n and ID<=(@n*10)

选择从n1到n2的记录
