Hi Experts,

I have the table with below columns
1.      ID
2.      WORK_ID
3.      VOLUME


It has a composite primary key ID and W_ID
Below is the data

ID       W_ID      VOL
1      1      10
2      2      10
3      2      10
3      3      10
1      4      15
3      5      10

Output : I want the ID and volume as out put, but calculating volume has some rules

1.      If Works is shared between ID’s, volume should be equally divided between them.

Sample out put depending on above table is

1 – 10 + 15 = 25
2 – 10/2 = 5 (Work 2 shared by both 2 and 3)
3 – 10/2 + 10 + 10 = 25

I need a query to get the above result.

 
Thanks,
Ravi
