SQL同比环比增长率计算

同比：

SELECT DISTINCT

?B.dateM,B.dateY,B.Total,B.Total+B.Total*AVG( B.per ) OVER ( PARTITION BY B.dateM ) as predictionTotal

?, ?AVG( B.per ) OVER ( PARTITION BY B.dateM ) AS [AvgPer]

?,MAX( B.per ) OVER ( PARTITION BY B.dateM ) AS [MaxPer]

?,Min( B.per ) OVER ( PARTITION BY B.dateM ) AS [MinPer] from?

?(SELECT A.dateM,A.dateY

?,A.[Total] - A.[PreviousTotal] as GrowthTotal,(A.[Total] - A.[PreviousTotal])/A.[PreviousTotal] as per,A.[Total]

, ?A.[Month]

FROM?

(

select s.dateM,dateY,COUNT(*) OVER ( PARTITION BY s.dateM ) AS [Month],s.[Total] ?AS [Total]

, ? LAG( s.[Total] ) OVER ( PARTITION BY s.dateM ORDER BY s.dateY ) AS [PreviousTotal]?

? ?from (SELECT datepart(mm,[month]) as dateM, datepart(yyyy,[month]) as dateY,sum([Total]) Total

FROM [KS_DataBase3.0_QJ].[dbo].[KS_MonthVbt] where [Month]>=2017 and [Month]<2019

GROUP BY [month]) s?

) AS A

) B?

?

同比排序比较简单

?

? SELECT o.*

FROM (SELECT o.*,?

? ? ? ? ? ? ?(total / LAG(total) OVER (ORDER BY month) - 1) as growth

? ? ? FROM [KS_DataBase3.0_QJ].[dbo].[KS_MonthVbt] o

? ? ?) o

WHERE [Month] <= 2019-10-01

ORDER BY [Month];
