sql - 获取除最后一行之外的最后 n 行的查询

Question

我有一张有 400 行的表。我想选择最后 6 行，不包括最后一行。

使用以下代码，我得到最后 6 行，但我不希望最后（第 400 行）存在

SELECT * 
FROM ImagesInfo 
WHERE Image_Id IN 
     (    SELECT TOP 6 Image_Id 
          FROM ImagesInfo 
          ORDER BY Image_Id DESC )

Answer 1

使用ROW_NUMBER()语法

SELECT * 
from
(
   SELECT *, ROW_NUMBER() over (ORDER By Image_ID) rn
   FROM yourtable 
) v
WHERE rn between x and y

Answer 2

SELECT top 6 *
FROM 
     (    SELECT TOP 7 *
          FROM ImagesInfo 
          ORDER BY Image_Id DESC 
     ) t
ORDER BY Image_Id

Answer 3

看看偏移量

SELECT First Name + ' ' + Last Name FROM Employees ORDER BY First Name OFFSET 10 ROWS FETCH NEXT 5 ROWS ONLY;

Answer 4

select top 6 * from image_info 
where image_id not in(select max(image_id) from image_info)
order by image_id desc

Answer 5

关于什么：

SELECT * FROM ImagesInfo
WHERE Image_Id IN (SELECT TOP 6 Image_Id FROM ImagesInfo ORDER BY Image_Id DESC) AND
      Image_Id <> (SELECT TOP 1 Image_Id FROM ImagesInfo ORDER BY Image_Id DESC)

或者

SELECT * FROM ImagesInfo
WHERE Image_Id IN (SELECT TOP 6 Image_Id FROM ImagesInfo ORDER BY Image_Id DESC) AND
      Image_Id <> (SELECT MAX(Image_Id) FROM ImagesInfo)

Answer 6

如果我理解正确（我不确定）那么你应该能够做到：

SELECT * 
FROM ImagesInfo 
WHERE Image_Id IN 
     (    SELECT TOP 7 Image_Id 
          FROM ImagesInfo 
          ORDER BY Image_Id DESC )
     and Image_Id not IN
     (    SELECT TOP 1 Image_ID
          FROM ImagesInfo
          ORDER BY Image_Id DESC )

Answer 7

尝试这个：

您只需从结果集中消除最大记录

 SELECT * 
FROM ImagesInfo 
WHERE Image_Id IN 
     (    SELECT TOP 6 Image_Id 
          FROM ImagesInfo 
          where Image_Id<> (select MAX(Image_Id) from ImagesInfo )
          ORDER BY Image_Id DESC )

或者

如果您使用的是sql server 2005 或更高版本：您可以使用ROW_NUMBER()和 CTE

with cte as(          
 SELECT *,
        ROW_NUMBER() over (order by Image_Id desc) as row_num 
 FROM ImagesInfo)           
 select * from cte where row_num between 2 and 7
