Linq to SQL Exists，GroupBy和Having

Question

我有这个SQL语句可以正常工作。我试图将此转换为VB Linq to SQL语句，没有任何运气。我被困在这里有人可以帮帮我吗？

SELECT P.*
FROM Product AS P
WHERE EXISTS (
    SELECT productid
    FROM Product_Promo AS PP
    WHERE P.productid = PP.productid
        AND P.Someid = 1003
        AND PP.ADate > getdate()
    GROUP BY productid
    HAVING COUNT(*) > 1
    );

我的VB.Net尝试：

From p In Products
Where (From pp In Product_Promo
    Where pp.ADate > DateTime.Now
    Select pp.productid
    Group By productid
    Into Group
    Where Group.Count > 1)
    .Contains(p.ProductID)
Select p
Where p.Someid = 1003

知道了！

Products.Where(Function(p) (p.Product_Promo.AsEnumerable().Count(Function(pp) ((p.SomeID = 1003) AndAlso (pp.ADate> DateTime.Now))) > 1))

感谢您的回答......
