每人涨10%的工资，涨的前一共不超过5万，从低工资往高工资的人涨，超过5W则停止涨，问涨的钱花了多少，多少人获得了涨薪。

 

;with test(CID,money,NewAmount) as (

SELECT  Row_Number() over ( order by money )  as CID 
      ,money
      ,money *0.1 as NewAmount
  FROM test107
)

select  b.CID , SUM(a.NewAmount ) sum_money, b.NewAmount
--distinct b.CID ,case when SUM(a.NewAmount ) > 50000 then 0 else b.NewAmount  end   as 涨薪 
from test   a  
left outer join 
test  b 
on a.CID <= b.CID     
group by b.CID, b.NewAmount   order by b.CID 


原表与上述代码结果。
