Question

我有这个SQL查询，它使用ROLLUP获取总数，但也需要按金额订购每隔一行：

SELECT 
    ISNULL([SharepointId], 'Total') as 'Sharepoint', 
    Count([Id]) as 'Nombre de tickets' 
FROM [dbo].[Tickets]
GROUP BY ROLLUP([SharepointId])
ORDER BY 2 DESC, 1

有没有办法确保总数保持在结果的末尾，同时保持其他行的降序？

现在，这就是我得到的：

Sharepoint         Nombre de tickets
------------------ -----------------
Total              20326
INTERNE            9396
MAIN               1503
...

Answer 1

其他答案错误地代表了你想要的东西。

您不希望行是最后一行，因为它是NULL
您想要一行是最后一行，因为它已被分组

SQL Server有一个完全相同的功能，而docs页面几乎就是你的例子......

https://docs.microsoft.com/en-us/sql/t-sql/functions/grouping-transact-sql?view=sql-server-2017

SELECT 
    ISNULL([SharepointId], 'Total') as 'Sharepoint', 
    Count([Id]) as 'Nombre de tickets' 
FROM [dbo].[Tickets]
GROUP BY ROLLUP([SharepointId])
ORDER BY GROUPING([SharepointId]), 2 DESC

GROUPING([SharepointId])为0当列不分组（因此这些行先排序）然后它是1列分组（以便该行最后一次）。这在卷起多列时特别有用。

Answer 2

试试这个

SELECT 
    ISNULL([SharepointId], 'Total') as [Sharepoint], 
    Count([Id]) as [Nombre de tickets]
FROM [dbo].[Tickets]
GROUP BY ROLLUP([SharepointId])
ORDER BY CASE WHEN [SharepointId] IS NULL THEN 'B' ELSE 'A' END, [Nombre de tickets] DESC

Answer 3

修改Order By子句，如下所示：

CASE WHEN  ISNULL([SharepointId], 'Total') <>'Total' THEN  
Count([Id])END DESC, 1

Answer 4

简单使用case表达式：

order by (case when SharepointId is null then 1 else 0 end), [Nombre de tickets] desc;

在SQL中没有Total的ORDER BY
