我有一份报告,其中我统计了各个国家/地区和SubRegions的报价。现在我有一些引号,其中Country为null。
Table
Quote Number | Country | Subregion | Quote Count
12233 | Germany | EMEA | 100
2223 | Blank | EMEA | 3333
3444 | France | EMEA | 200
455454 | Spain | EMEA | 300
总票数无空国家说等于1000,其中10%与德国等有关。因此德国加权因子为0.1。
总的来说,我有3333个引号,其中country字段为空。因此,我被要求获取EMEA的报价,并使用基于报价当前价差的加权因子在德国,西班牙,法国和其他EMEA国家/地区之间分配报价,然后将报价添加到该地区的其他国家,如EMEA。
所以目前我对如何做到完全感到困惑?有什么想法吗?
帮助?有人吗?
第1步 - 获取EMEA所有国家/地区的当前加权因子。在sql?
第2步 - 获取没有为EMEA指定国家/地区的报价的报价计数。在sql?
步骤3 - 根据称量因子获取报价并向每个国家/地区添加x引号。在sql?

根据样本中的数据:
WITH Factors
AS ( SELECT Country ,
SUM([Quote Count])
/ CAST(( SELECT SUM([Quote Count])
FROM dbo.quotes
WHERE Region = q.Region
AND Country IS NOT NULL
) AS FLOAT) AS WeightingFactor ,
q.Region
FROM dbo.quotes q
WHERE country IS NOT NULL
GROUP BY q.Country ,
q.Region
)
SELECT q.country ,
( SELECT SUM([quote count])
FROM dbo.quotes
WHERE Country IS NULL
AND Region = q.Region
) * f.WeightingFactor + SUM(q.[Quote Count]) AS [Quote Count]
FROM dbo.quotes q
JOIN Factors f ON q.Country = f.Country
AND q.Region = f.Region
WHERE q.Country IS NOT NULL
GROUP BY q.Country ,
q.Region ,
WeightingFactor

要获得加权因子,请执行以下操作:
select country, quotecount,
quotecount*1.0/sum(quotecount) over (partition by null) as allocp
from t
where country <> 'Blank'
要重新添加这些内容,请加入总计:
select t.country, t.region, t.quotecount,
(t.quotecount + allocp*b.BlankBQ) as AllocatedQC
from (select country, quotecount,
quotecount*1.0/sum(quotecount) over (partition by region) as allocp
from t
where country <> 'Blank'
) t join
(select sum(QuoteCount) as BlankBQ
from t
where country = 'Blank'
group by region
) b
on t.region = b.region
