double precision, month integer, n integer, s integer ); INSERT
INTO sale2 (year, month, n, s) VALUES (2019, 1, 1, 37) , (2019, 1,
2, 63) , (2019, 1, 3, 22) , (2019, 1, 4, 27) , (2019, 2, 1, 27) ,

I need to get the maximum total sales and month and year
right now I have something like this
select year, month, tt from (select year, month, sum(s) tt from
sale2 group by year, month) t1
order by tt desc;
all what I need is to choose the first row only.
