Question

I have this table:

name    count1    count2   address
John      5         0      London
John      0         3      London
Phil      1         0      Paris

I want to get

name    count1    count2   address
John      5         3      London
Phil      1         0      Paris

So I want to sum count1 and sum count2 and group by name but merge address (since address is always going to be the same for each name)

Answer 1

This is SQL aggregates 101 (which I’m still learning, btw):

select name, sum(count1), sum(count2), address
from mytable
group by name, address;
