I have a problem with this case :
I have 10 candy for 7 child (A, B, C, D, E, F, G).
Table X :
code value
------- --------
A 0
B 0
C 0
D 0
E 0
F 0
G 0
And I want divide it with this algorithm :
A = 10 / 7 = 1
B = (10-1) / (7-1) = 9 / 6 = 1
C = (10-2) / (7-2) = 8 / 5 = 1
D = (10-3) / (7-3) = 7 / 4 = 1
E = (10-4) / (7-4) = 6 / 3 = 2
F = (10-6) / (7-5) = 4 / 2 = 2
G = (10-8) / (7-6) = 2 / 2 = 2
In my first solution i use loop - for each record in my function.
But it is too slow in a lot of data.
Did postgresql have a function for my case?
Thanks All.
