Question

I have this table :

Name   |  money_earned
_______________________

john   |   100
paul   |   200
ringo  |   300
george |   200

I want to calc ( in the most intelligent way) – near each row

What is the percentage of benefit( of each beatle) – relative to the total sum

So i want a reult like this : ( the sum is 800)

Name   |  money_earned| his_Percentage
__________________________________

john   |   100        |   0.125
paul   |   200        |   0.25
ringo  |   300        |   0.375
george |   200        |   0.25

Thank 🙂

edit

I’ll be glad to have a solution like rollup does.

it count the sum , and overall sum…something like this function.

So lets say I want it in 1 query without declaring extra pre-calculated values.

Answer 1

select Name,
       money_earned,
       money_earned / sum(money_earned) over() as his_Percentage
from [Table]
