MySQL Multiple Columns Sum() in different / multiple rows

Question

I have basic table looking like:

When I am using the Query:

SELECT *, SUM(cr) AS cr, SUM(dr) AS dr FROM my_table GROUP BY id

I am getting:

and that's correct!

What's the proper query to get (each sum in different row):

I already tried GROUP BY ID,CR,DR and GROUP BY CR,DR,ID but with not the results that I wanted. (I don't care if the 0 values are also NULL)

Answer 1

You can do:

select id, sum(dr) as dr, 0 as cr from my_table group by id
union all
select id, 0, sum(cr) from my_table group by id
order by id, dr desc
