> ex: I have some sample data like this:
Inputs Outputs
ID | iAmount ID | oAmount
1 |10 1 |2
2 |20 2 |5
3 |9 4 |6
> I need result as: amount = iAmount - oAmount event they do not exists in both table
**Results**
ID | Amount(iAmount - oAmount)
1 | 8
2 | 15
3 | 9
4 | 6
How can I solve it and any solution to get result from Inputs and Output to get Results like that?
