mysql“is in”等价?

不久前,我在一个MS-SQL项目上工作,我记得有一个“正在”的东西。我在一个MySQL项目上尝试过,但没有成功。

有等价物吗?解决问题?

下面是我试图运行的完整查询:

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

它相当大…但我感兴趣的是:

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)

基本上说,我希望产品在该子查询的“前10位”。

您如何使用MySQL实现这一点(同时努力提高效率)?
