如何将总计行从 order by 中排除并显示在表 ssms 18 的底部

Question

这是我现在的代码。输出表中有 4 行，我想知道如何在表底部显示总计行。由于 DESC 的顺序，它目前显示在顶部。

USE [MyData]

SELECT * INTO tableOne FROM [DataLib].[dbo].[Lease] -- carry over Lease table from Data Library to Reporting Database

--populate new table with the 3 commerical sectors and their uniqu
CREATE TABLE commercial_expirations (
    UniqueID varchar(255),
    PropertyType varchar(50))

INSERT INTO commercial_expirations
VALUES  ('Asset / Most Recent Quarter / All Assets / Sector | Industrial','Industrial'),
        ('Asset / Most Recent Quarter / All Assets / Sector | Office','Office'),
        ('Asset / Most Recent Quarter / All Assets / Sector | Retail','Retail'),
        ('Asset / Most Recent Quarter / All Assets / SectorType | Commercial','Total')

SELECT  c.PropertyType AS 'Property Type',
        e.SpaceArea_End AS 'RentableSF',
        FORMAT(e.LsDuration_WAvg, 'N1') AS 'WA Duration (Yrs)',
        FORMAT(e.[LsArea%_End], 'P1') AS '%Leased',
        FORMAT(e.[Year0ExpireArea%], 'P1') AS '2021',
        FORMAT(e.[Year1ExpireArea%], 'P1') AS '2022',
        FORMAT(e.[Year2ExpireArea%], 'P1') AS '2023',
        FORMAT(e.[Year3ExpireArea%], 'P1') AS '2024',
        FORMAT(e.[Year4ExpireArea%], 'P1') AS '2025',
        FORMAT(iif(e.[Year5ExpireArea%] IS NULL, 0, e.[Year5ExpireArea%]) + iif(e.[Year6ExpireArea%] IS NULL, 0, e.[Year6ExpireArea%]) + iif(e.[Year7ExpireArea%] IS NULL, 0, e.[Year7ExpireArea%]) + iif(e.[Year8ExpireArea%] IS NULL, 0, e.[Year8ExpireArea%]) + iif(e.[Year9ExpireArea%] IS NULL, 0, e.[Year9ExpireArea%])  + iif(e.[Year10ExpireArea%] IS NULL, 0, e.[Year10ExpireArea%]) + iif(e.[Year11PlusExpireArea%] IS NULL, 0, e.[Year11PlusExpireArea%]), 'P1')  AS 'Thereafter'

INTO ##Schedule

FROM commercial_expirations AS c
LEFT JOIN tableOne AS e
ON c.UniqueID = e.RecordID;

SELECT  [Property Type],
        FORMAT(RentableSF, 'N0') AS 'Rentable SF',
        [WA Duration (Yrs)],
        [2021],
        [2022],
        [2023],
        [2024],
        [2025],
        Thereafter

FROM ##Schedule
ORDER BY [RentableSF] DESC;



/*
DROP TABLE commercial_expirations
DROP TABLE expSummary
DROP TABLE ##Schedule
*/

Answer 1

这是我将所有这些代码转换为单个查询的最佳尝试。由于我没有数据库、架构或脚本来验证查询，因此我将调试留给您。

with commercial_expirations as (
   select * from (
   VALUES  ('Asset / Most Recent Quarter / All Assets / Sector | Industrial',    'Industrial'),
           ('Asset / Most Recent Quarter / All Assets / Sector | Office',        'Office'),
           ('Asset / Most Recent Quarter / All Assets / Sector | Retail',        'Retail'),
           ('Asset / Most Recent Quarter / All Assets / SectorType | Commercial','Total')
   ) as x(UniqueID, PropertyType)
)
select ... 
from commercial_expirations as cexp
left join [DataLib].[dbo].[Lease] as lease -- why use a three-part name here? THINK!! 
  ON cexp.UniqueID = lease.RecordID
order by 
    case cexp.PropertyType when 'Total' then 1 else 0 end, 
    lease.SpaceArea_End DESC
;

小心使用由三部分组成的名称。它使您的代码变得脆弱，因为它需要在使用不同的环境时进行更改。一般来说，您的连接应确定用于对象（表）引用的数据库。我建议你真的在 sql 查询中使用 FORMAT，因为它是一项昂贵的操作。格式化是表现层最好的功能。

最后的建议。停止使用这种 编码方法的惰性模式。将复杂查询分解为可实现的部分是一个好主意，但这一切都可以作为一个过程来完成，即从针对感兴趣的表的基本查询开始，然后添加实现所需结果所需的连接和功能。有时有理由具体化底层查询 - 当有证明有好处时这样做。否则让数据库引擎优化器做它设计做的事情。

经常看到人们使用该模式只是将这些脚本推送到生产环境并继续执行下一个任务——从不尝试清理或优化它。这只会强化坏习惯。开始学习良好的习惯。

要将总行强制到顶部，您可以添加

  CASE WHEN c.PropertyType = 'Total' THEN 1 ELSE 2 END

到ORDER BY 子句的开头。

您还可以通过多种方式简化和改进此查询：

• 将 commercial_expirations 更改为 CTE 中的虚拟表
• 将临时表组合到一个查询中
• 使用ISNULL 而不是IIF(... IS NULL
• 使用[] 引用列名
  • 理想情况下，您根本不需要引用列名，请谨慎选择名称
• 按实际值排序，而不是按格式表示

WITH commercial_expirations AS (
    SELECT *
    FROM (VALUES  
        ('Asset / Most Recent Quarter / All Assets / Sector | Industrial','Industrial'),
        ('Asset / Most Recent Quarter / All Assets / Sector | Office','Office'),
        ('Asset / Most Recent Quarter / All Assets / Sector | Retail','Retail'),
        ('Asset / Most Recent Quarter / All Assets / SectorType | Commercial','Total')
    ) v(UniqueID, PropertyType)
)
SELECT  c.PropertyType AS [Property Type],
        FORMAT(e.SpaceArea_End, 'N0') AS RentableSF,
        FORMAT(e.LsDuration_WAvg, 'N1') AS [WA Duration (Yrs)],
        FORMAT(e.[LsArea%_End], 'P1') AS [%Leased],
        FORMAT(e.[Year0ExpireArea%], 'P1') AS [2021],
        FORMAT(e.[Year1ExpireArea%], 'P1') AS [2022],
        FORMAT(e.[Year2ExpireArea%], 'P1') AS [2023],
        FORMAT(e.[Year3ExpireArea%], 'P1') AS [2024],
        FORMAT(e.[Year4ExpireArea%], 'P1') AS [2025],
        FORMAT(
            ISNULL(e.[Year5ExpireArea%], 0) +
            ISNULL(e.[Year5ExpireArea%], 0) +
            ISNULL(e.[Year6ExpireArea%], 0) +
            ISNULL(e.[Year7ExpireArea%], 0) +
            ISNULL(e.[Year8ExpireArea%], 0) +
            ISNULL(e.[Year9ExpireArea%], 0) + 
            ISNULL(e.[Year10ExpireArea%], 0) + 
            ISNULL(e.[Year11PlusExpireArea%], 0), 'P1')  AS [Thereafter]
FROM commercial_expirations AS c
LEFT JOIN tableOne AS e
  ON c.UniqueID = e.RecordID;
ORDER BY
  CASE WHEN c.PropertyType = 'Total' THEN 1 ELSE 2 END,
  e.SpaceArea_End DESC;
