I have a table structure like following:
Users => Histories <= Brands
Histories table keeps following columns: userId, brandId, points
I have a query like following:
select b.id, sum(h.points),h.brandId
from brands b left join
histories h
on b.id = h.brandid and h.userId = 2866
group by b.id;
This query returns me brands where USER made points and didnt make any points at all..
I wanna add a filter to a brandId as well so that the query doesn't returns all results, but a single result at a time depending what brandId has been sent to the query... How can I and where can I add a statement which would return me a single record for this query?? So basically I just need to pass brandId = to something statement, leaving the query it self as it is right now ... :)
For example if brand id is 100:
select b.id, sum(h.points),h.brandId
from brands b left join
histories h
on b.id = h.brandid and h.userId = 2866
where b.id=100
group by b.id
limit 1;
