sql 创建一个索引 ID 作为新列来对我刚刚创建的案例类别进行排序 Sql server

Question

我想创建一个 SortID 列来对不同案例类别的结果进行排序。每个案例类别代表一个收入范围。我按案例报表上的结果进行分组，以获得每个案例的订单数量。现在我被这个 SortID 创建问题困住了。请在下面找到我当前的查询。请建议我在哪里可以将索引创建语句放在查询中。非常感谢提前！

select SalesAmountCategory, count(*) as Orders 
from
    (Select case
            when ((SalesAmount-TaxAmt-Freight)>=100000) then '>$100000'
            when ((SalesAmount-TaxAmt-Freight)>=50000) then '$50000-$100000'
            when ((SalesAmount-TaxAmt-Freight)>=10000) then '$10000-$50000'
            when ((SalesAmount-TaxAmt-Freight)>=5000) then '$5000-$10000'
            when ((SalesAmount-TaxAmt-Freight)>=2500) then '$2500-$5000'
            when ((SalesAmount-TaxAmt-Freight)>=1000) then '$1000-$2500'
            when ((SalesAmount-TaxAmt-Freight)>=500) then '$500-$1000'
            when ((SalesAmount-TaxAmt-Freight)>=100) then '$100-$500'
            when ((SalesAmount-TaxAmt-Freight)<100) then '$0-$100'
            end as SalesAmountCategory
        From  dbo.FactResellerSales 
        where OrderDate BETWEEN '2010-01-01 00:00:00.000' AND '2010-12-31 23:59:59.999'
    ) as t
    group by SalesAmountCategory
    order by SalesAmountCategory;

请在下面找到图片作为预期结果示例

Answer 1

我会使用apply而不是子查询，你可以使用row_number来创建sortid：

select row_number() over (order by min(SalesAmount - TaxAmt - Freight)) as sortid,
       SalesAmountCategory, count(*) as Orders
from dbo.FactResellerSales frs cross apply
     ( values (case when (SalesAmount - TaxAmt - Freight) >= 100000 then '>$100000'
                    when (SalesAmount - TaxAmt - Freight) >= 50000) then '$50000-$100000'
                    . . .
                    when (SalesAmount - TaxAmt - Freight) < 100 then '$0-$100'
               end)
     ) frss(SalesAmountCategory)
where OrderDate BETWEEN '2010-01-01 00:00:00.000' AND '2010-12-31 23:59:59.999'
group by SalesAmountCategory;

Answer 2

不是按类别排序，而是按每个类别的最小数量排序：

select row_number() over (order by min(SalesAmount-TaxAmt-Freight)) as sortid,
. . . 
order by min(SalesAmount-TaxAmt-Freight)

当然，您还需要在子查询中选择这些列（或在子查询中进行计算）。
