5 1005 17:50 0 1 0 0 0
sums 5 1 2 2 0 AA

AA = 3, if AA is the sum of sums! = 0, what to do ??

What does the last sentence mean?

The last item is to find the number of items whose sums are not equal to 0

create table T (ID int, product ID char (4), time char (5), v1 int, v2 int, v3 int, v4 int, sums int)
insert T select 1, '1001', '17: 10 ', 0, 0, 0, 0, 0
union all select 2, '1002', '17: 20 ', 1, 0, 1, 0, 2
union all select 3, '1003', '17: 30 ', 0, 1, 0, 0, 1
union all select 4, '1004', '17: 40 ', 0, 0, 1, 0, 1
union all select 5, '1005', '17: 50 ', 0, 1, 0, 0, 1

select ID = rtrim (ID), product ID, '' time, rtrim (v1), rtrim (v2), rtrim (v3), rtrim (v4), rtrim (sums) sums from T
union all
select 'sums', count (*), '', rtrim (sum (v1)), rtrim (sum (v2)), rtrim (sum (v3)), rtrim (sum (v4)), 'AA' sums from T

我是杀人狂

select id = sums, product ID = count (product ID), time = '', v1 = sum (v1), v2 = sum (v2), v3 = sum (v3), v4 = sum (v4), sums = sum (sums) from tablename

我是杀人狂

select id = sums, product ID = count (product ID), time = '', v1 = sum (v1), v2 = sum (v2), v3 = sum (v3), v4 = sum (v4), sums = sum (case when sums <> 0 then 1 else 0 end) from tablename

michealhenry

sum (case sums when 0 then 0 else 1 end) as AA

select ID = rtrim (ID), product ID, time, rtrim (v1), rtrim (v2), rtrim (v3), rtrim (v4), rtrim (sums) sums from #t
union all
select 'sums', count (*), '', rtrim (sum (v1)), rtrim (sum (v2)), rtrim (sum (v3)), rtrim (sum (v4)), sum (sums) sums from #t
