Question

我想知道如何根据条件从特定表中获取101-150行之间的结果，如下所示：

SELECT * FROM Students
WHERE Student_Status = 'Cancelled';

可以有多个学生状态，所以我只想要取消学生的结果在101 - 150之间。

Answer 1

使用具有适当排序的row_number窗口函数对行进行排名：

select * from
(select *, row_number() over(order by StudentID) as rn 
 from Students where Student_Status = 'Cancelled') t
where rn between 101 and 150

Answer 2

与Giorgi的答案相同，但使用CTE写一个不同的方法;我发现它更容易阅读和使用。

;WITH t1 AS
(
    SELECT ROW_NUMBER() OVER(ORDER BY StudentID) AS RID, *
    FROM Students
    WHERE Student_Status='Cancelled'
)

SELECT *
FROM t1
WHERE RID BETWEEN 101 AND 150

Answer 3

抵消提取可能是您正在寻找的内容：

SELECT * 
FROM Students 
WHERE Student_Status = 'Cancelled'
ORDER BY StudentId 
OFFSET 100 ROWS FETCH NEXT 50 ROWS ONLY

示例：

declare @table table (id int)

declare @int int = 1

while @int < 200
begin
    insert into @table values (@int)
    set @int = @int+1
end

select id
from @table 
order by id 
offset 100 rows fetch next 50 rows only

Answer 4

正如指出的那样，Giorgi OFFSET和NEXT仅在2012年上市所以这在2008年不起作用留下它让人们意识到它可以在2012年使用

SELECT * FROM Students 
 WHERE Student_Status = 'Cancelled' 
 ORDER BY StudentID 
OFFSET 100 ROWS
 FETCH NEXT 50 ROWS ONLY;

ORDER BY

Answer 5

DECLARE @RowsPerPage INT = 50; 
DECLARE @PageNumber INT = 3; 
SELECT *
FROM Students
WHERE Status = 'Cancelled' 
ORDER BY StudentID
OFFSET (@PageNumber - 1) * @RowsPerPage ROWS
FETCH NEXT @RowsPerPage ROWS ONLY

sql查询得到第3组结果，如果每组保存50个结果
