Hi everyone
I'm not very good at SQL
I tried to get the amount of sale (promotion item) on each city

SQL

select distinct l.city, p.name as promotion_name, s.count
from location l, promotion p, sale s
where s.locationID=l.id and s.promotionID=p.id
and l.city = 'London' or l.city='Leeds'
or l.city = 'Slough' or l.city='Grays'
and p.name= 'super sale' or p.name='best sale'

Any help ?

Well, you have not stated the exact structure of the tables. I think you should go through group by in sql[^]

Solution 2

Try this

SQL

select distinct l.city, p.name as promotion_name, count(s.id)
from location l, promotion p, sale s
where s.locationID=l.id and s.promotionID=p.id
and p.name= 'super sale' or p.name='best sale'
Group By l.city, p.name

If you want each city's sale then no need to add in where condition
