Answer Source


SELECT x.sub_id
     , MAX(x.num1) num1
     , MAX(CASE WHEN x.num1 <> 0 THEN x.date END) num1_date
     , MAX(x.num2) num2
     , MAX(CASE WHEN x.num2 <> 0 THEN x.date END) num2_date 
  FROM my_table x 
    BY x.sub_id;

But, generally, I think it's best to resolve issues of data display such as this in application code.
