I am having data of table dummy as below:

Name                       amount      amount1
-----------------------------------------------
mahesh                     1200        Null
mahesh                     1000        Null
mahesh                     Null        25000
mahendra                   1200        Null
Kirti                      null        22000

I am trying to prepare a list like below:

Name                       amount      amount1
-----------------------------------------------
mahesh                                 22800
mahendra                   1200
kirti                                  22000

Answer 1

Looks like you’re adding numbers where amount is negative and amount1 is positive. You can do that with a group by. A case can help place the resulting sum in the right column:

select  name
,       case 
        when sum(amount1 - amount) < 0 then -sum(amount1 - amount) 
        end as amount
,       case 
        when sum(amount1 - amount) >= 0 then sum(amount1 - amount) 
        end as amount1

group by
       name
