How to calculate sum on values based on certain rules

Hi,

 

In my table below, I am trying to solve this issue for the value of KEY1. So for all IDs belonging to the same KEY3 (for e.g. IDs:1,2,3 all belong to KEY3: A), the value of KEY1, where KEY2 = X, should be the sum of all KEY1 values belonging to the same KEY3 (for e.g. KEY1s:200,300,500 all belong to KEY3: A). I've added another table below to show what the result should look like.

 

IDKEY1KEY2KEY3
1200 A
2300XA
3500 A
4800XB
5100 B
6700 C
7400 C
8600XC
9200 D

 

This is what the result should look like (change in KEY1 values, where KEY2 = X):

 

IDKEY1KEY2KEY3
1200 A
21000XA
3500 A
4900XB
5100 B
6700 C
7400 C
81700XC
9200 D

 

Thank you! Much appreciated!

Hi @Jairacha ,

 

nice and simple.

Just sum the KEY1 value grouped by KEY3 then join back to the isolated rows where KEY2=X. This replaces the KEY1 value for these records. Then union back together and sort accordingly.

Hope this helps,
