Here is a completely debugged script, using your data, with the answers
from your specification rather than you example. GO is my GUI's
statement separator. I rearranged the visitors_sent table to make the
primary key stand out.
create table salesmen(
id smallint not null,
name varchar(10),
primary key(id))
go
insert into salesmen
values (1,'bobby'),
(2,'steeve'),
(3,'john')
go
create table visitors_sent (
salesman smallint not null,
hour smallint not null,
total smallint,
sales smallint,
primary key(salesman,hour))
go
insert into visitors_sent
values (3, 12, 11, 3),
(1, 12, 8, 2),
(2, 12, 15, 2),
(1, 11, 4, 1),
(2, 11, 5, 2)
go
select t1.id, t1.name, sum(t2.sales)*100/sum(t2.total) as pct
from salesmen t1
join visitors_sent t2 on t2.salesman=t1.id
group by t1.id, t1.name
order by sum(t2.sales)*100/sum(t2.total)
go
The results were:
ID NAME PCT
----- ------- ------
2 steeve 20
1 bobby 25
3 john 27
