環比增長：

WITH f AS 
(
  SELECT ROW_NUMBER()OVER(   partition by fdSequenceID ORDER BY fdTime) AS id, * FROM [NewDBTest].[dbo].[tbDataMonthHG] where fdSequenceID <100
)
 
select t.*,
       fdRate=(cast(cast(100*((t.fdData/NULLif(d.fdData,0))-1) as numeric(25,10)) as  varchar(50))+'%' )   --將分數變為百分數
       from f t
       
left join f d on
       t.fdInnerTime = DateAdd(month,1,d.fdInnerTime) and t.fdSequenceID = d.fdSequenceID   --獲取根據時間獲取上月時間
       order by fdSequenceID,id asc 

 某一時間點與相鄰的上一個時間的增長

 

WITH f AS 
(
  SELECT ROW_NUMBER()OVER(   partition by fdSequenceID ORDER BY fdTime) AS id, * FROM [NewDBTest].[dbo].[tbData]
)
SELECT  
  t.fdSequenceID,t.fdInnerTime,t.fdTime,t.fdData,t.fdState,t.fdUpdateTime,t.fdCreateTime,t.id,
  (select cast(cast(100*((t.fdData/NULLif(d.fdData,0))-1) as numeric(35,10)) as  varchar(50))+'%') AS fdRate
  from f t 
  LEFT JOIN f d on t.id=d.id+1 where t.fdSequenceID = d.fdSequenceID  ORDER by t.fdSequenceID ASC 
  

-- 不會返回null



WITH f AS 
(
  SELECT ROW_NUMBER()OVER(   partition by fdSequenceID ORDER BY fdTime) AS id, * FROM [NewDBTest].[dbo].[tbData] where fdSequenceID<188
)

select t.*,
       cast(cast(100*((t.fdData/NULLif(d.fdData,0))-1) as numeric(25,10)) as  varchar(50))+'%' 
       from f t
left join f d
       on datediff(day, 
                   DateAdd(day,d.id-1,DateAdd(month,d.fdSequenceID-1,'1900-1-1')),
                   DateAdd(day,t.id-1,DateAdd(month,t.fdSequenceID-1,'1900-1-1'))
                   ) > 0

-- 會返回null
