Something like this:
```
create table sales(product,year,sales);
insert into sales values('A','2000',0); -- excluded because zero
insert into sales values('A','2001',10);
insert into sales values('A','2002',20);
insert into sales values('A','2003',20); -- excluded by year range
insert into sales values('B','2000',5);
insert into sales values('B','2001',10);
insert into sales values('B','2002',0); -- excluded because zero
insert into sales values('B','2003',100); -- excluded by year range
select product,min(sales),avg(sales),max(sales) from sales
where year between '2000' and '2002'
and sales > 0
group by product;
```
Adjust `WHERE` according to the years you need.
