A while ago I worked on a MS-SQL project and I remember a "IS IN" thing. I tried it on a MySQL project and it did not work.

Is there an equivalent? Workaround?

Here is the full query I am trying to run:

SELECT *
FROM product_product, product_viewhistory, product_xref
WHERE 
(
(product_viewhistory.productId = product_xref.product_id_1 AND product_xref.product_id_2 = product_product.id)
OR 
(product_viewhistory.productId = product_xref.product_id_2 AND product_xref.product_id_1 = product_product.id)
)
AND product_product.id IS IN 
    (SELECT DISTINCT pvh.productId
    FROM product_viewhistory AS pvh
    WHERE pvh.cookieId = :cookieId
    ORDER BY pvh.viewTime DESC
    LIMIT 10)
AND product_viewhistory.cookieId = :cookieId
AND product_product.outofstock='N'
ORDER BY product_xref.hits DESC
LIMIT 10

It's pretty big ... but the part I am interested in is:

AND product_product.id IS IN 
    (SELECT DISTINCT pvh.productId
    FROM product_viewhistory AS pvh
    WHERE pvh.cookieId = :cookieId
    ORDER BY pvh.viewTime DESC
    LIMIT 10)

Which basically says I want the products to be in the "top 10" of that sub-query.

How would you achieve that with MySQL (while trying to be efficient)?
