table 2

Answer 1

I craeted this query, it works, but I bet there is a better and more efficient way to do it, can anyone out there help?

select q.*
from (
            select     QuoteObservations.id, QuoteObservations.value,   QuoteObservations.quotePointId, max(QuoteObservations.asOfTime) as asOfTime, QuoteObservations.dataProviderId, qp.quoteType
            from [QuoteObservations]
            inner join QuotePoints qp
            on qp.id = QuoteObservations.quotePointId
            where quotePointId = 1
            group by QuoteObservations.id, QuoteObservations.value, QuoteObservations.quotePointId, QuoteObservations.dataProviderId
    ) q
inner join (

            select     QuoteObservations.id, QuoteObservations.value, QuoteObservations.quotePointId, max(QuoteObservations.asOfTime) as asOfTime, QuoteObservations.dataProviderId, qp.quoteType
            from [QuoteObservations]
            inner join QuotePoints qp
            on qp.id = QuoteObservations.quotePointId
            where quotePointId = 2
            group by QuoteObservations.id, QuoteObservations.value, QuoteObservations.quotePointId, QuoteObservations.dataProviderId
) p
    on  q.id = p.id
inner join (
            select     QuoteObservations.id, QuoteObservations.value, QuoteObservations.quotePointId, max(QuoteObservations.asOfTime) as asOfTime, QuoteObservations.dataProviderId, qp.quoteType
            from [QuoteObservations]
            inner join QuotePoints qp
            on qp.id = QuoteObservations.quotePointId
            where quotePointId = 10
            group by QuoteObservations.id, QuoteObservations.value, QuoteObservations.quotePointId, QuoteObservations.dataProviderId
) s
    on  s.id = p.id
