SQL查询LINQ To SQL等效

Question

请告诉我如何将这个SQL查询转换成LINQ To SQL？提前致谢。

SELECT [Movies].[Name] 
FROM 
(
    SELECT [Value] 
    FROM [Index] 
    WHERE ('WORD1' = [Word] and [MatchCount] = 1) 
    OR ([Word] = 'WORD2' AND [MatchCount] = 1) 
    GROUP BY [Value] 
    HAVING COUNT([Value]) = 2 
) AS [Guids] 
LEFT OUTER JOIN [Movies] ON [Movies].[Guid] = [Guids].[Value] 

Answer 1

是这样的？ （警告，以下代码未经测试！）

var q = from i in Index 
    where i.MatchCount == 1 && 
    (i.Word == "WORD1" || i.Word == "WORD2") 
    group i by i.Value into g 
    where g.Count() == 2 
    from m in Movies.Where(x => x.Guid == g.Key).DefaultIfEmpty() 
    select m.Name; 

Answer 2

在a previous question，有人建议Linqer。

我从来没有用过它，老实说，但我已经广泛使用LinqPad。它做相反的（以及转换LINQ到lambda表达式），并且是我最喜欢的工具之一。
