Question

I’m struggling to make this work, this query should give the deal with the cheapest price between two dates but somehow it’s giving the cheapest offer always and it kinda ignores the date

SELECT offer_id 
FROM travel_offers o
WHERE price = (
    SELECT MIN(price) as minprice 
    FROM travel_offers om 
    WHERE 
        o.latitude = om.latitude AND
        o.longitude = om.longitude AND
        (o.time_from BETWEEN '2012-07-01' AND '2012-11-31') 
        AND
        (o.time_to BETWEEN '2012-07-01' AND '2012-11-31')
)

Answer 1

SELECT offer_id, MIN(price) as minprice 
FROM travel_offers
WHERE 
    time_from BETWEEN '2012-07-01' AND '2012-11-31'
    AND
    time_to BETWEEN '2012-07-01' AND '2012-11-31'
    and 
    time_from <= time_to
group by offer_id
order by minprice
limit 1
