Question

我整个下午都在这里查看了一些类似的查询，但是无法正确查询。

我正在尝试返回与所需年份的唯一ID的一组结果中的最大值相关联的标签。这是代码+输出：

select 
    fs_perm_sec_id, YEAR(date) as [Date by Year], label, sales 
from 
    ff_v2.ff_segreg_af
where 
    fs_perm_sec_id = 'SN9W4D-S-US'
    and YEAR(date) = '2013'

示例数据：

fs_perm_sec_id  Date by Year    label   sales
SN9W4D-S-US 2013    Japan   26592.96196
SN9W4D-S-US 2013    Europe  16445.23016
SN9W4D-S-US 2013    United States   12851.71355
SN9W4D-S-US 2013    Other Countries 10855.52867
SN9W4D-S-US 2013    Asia Pacific    9730.89435
SN9W4D-S-US 2013    China   5609.94288

所以在这种情况下，我想返回fs_perm_sec_id，[Date by Year]和Label - （不需要销售值）。因此，我想返回

SN9W4D-S-US | 2013 | Japan ...as my output

请记住，原始表有多个fs_perm_sec_id和日期条目。因此，最终我想强调标签与年度为2013年的所有独特条目的最大销售价值相匹配。

以下是表格中所有字段的示例：

fs_perm_sec_id  date    ff_segment_type ff_segment_num  adjdate currency    label   sales   opinc   assets  capex   dep

非常感谢v.much提前。

Answer 1

试试这个

select fs_perm_sec_id, [Date by Year], label
from
(
select 
    fs_perm_sec_id, YEAR(date) as [Date by Year], label, DENSE_RANK ( ) OVER (order by sales desc) as RankNo
from 
    ff_v2.ff_segreg_af
where 
    fs_perm_sec_id = 'SN9W4D-S-US'
and YEAR(date) = '2013'
) r
where RankNo = 1

Answer 2

最终代码是：

use FDS3
select fs_perm_sec_id, [Date by Year], label
from
(select fs_perm_sec_id, YEAR(date) as [Date by Year], label, DENSE_RANK ( ) 
OVER (partition by fs_perm_sec_id order by sales) as RankNo
from ff_v2.ff_segreg_af where 
fs_perm_sec_id in 
('SN9W4D-S-US',
'HSDCT7-S-US',
'WHQNFK-S-US',
'PRM2JP-S-US',
'R2KQ06-S-US',
'L7GJB9-S-US',
'P47Z0J-S-US')
and YEAR(date) = '2013'
) r
where RankNo = 1

从组中返回所需年份的最大值
