Is this what you mean?

select 
  customer_id, name, 
  sum( if(date_of_operation='2016-1-1',amount,0) ) as jan1,
  sum( if(date_of_operation between '2016-1-1' and '2016-1-31',amount,0) ) as restofjan,
from customers_logs 
group by customer_id, name
having jan1>0 and restofjan>0;

Note that with `name` not aggregated in the Select list, it needs to be in the Group By list unless your DDL enforces that all name values are unique to corrsponding id values.
