thanks for your feedback but no record is returned.....there was a mistake in your query(I replaced the where to ON near the inner join)

select pp.id, pp.priceDate, pp.purchasePrice, pp.salesPrice, pp.consumerPrice, p.productID, pp.description
  from product p
        inner join productPricing pp1 
    on pp1.productID = p.ProductID
 where p.supplierID=3 
   and exists (select pp2.ProductID, MAX(pp2.priceDate) as max_priceDate 
                 from productPricing pp2 
                where pp2.productID = pp1.productID 
                group by pp2.ProductID 
               having MAX(pp2.priceDate) = pp1.priceDate)

try only this

Select p1.productID ,Max(p1.priceDate) from productPricing p1
group by p1.productID

this will return you two records you want
then you need to join this table with your query
This needs to work.
Let me know if this query gives you appropriate result

select
pp.id,
pp.priceDate,
pp.purchasePrice,
pp.salesPrice,
pp.consumerPrice,
pp.productID,
pp.description
from
productPricing pp cross
join
product p
inner join
(
Select p1.productID ,Max(p1.priceDate) from productPricing p1
group by p1.productID

) X on X.productID = pp.productID
where
pp.productID=p.id
and p.supplierID=3

I get this error when I run your second query

No column name was specified for column 2 of 'X'.
