Question

我的数据库中有vw_AllNomenLost视图

SELECT     TOP (100) PERCENT ProducerName, NomenCode, SUM(ErrorCount) AS ErrorCount
FROM         dbo.NomenLost
GROUP BY ProducerName, NomenCode
ORDER BY ErrorCount DESC

我将它添加到实体模型。

我想通过Producer排名前10行并按ErrorCount

排序

db.vw_AllNomenLost.Where(a => a.ProducerName == producer).OrderByDescending(a => a.ErrorCount).Take(10);

在调试器中我得到：

SELECT TOP (10) 
    [Project1].[NomenCode] AS [NomenCode], 
    [Project1].[ProducerName] AS [ProducerName], 
    [Project1].[ErrorCount] AS [ErrorCount]
    FROM ( 
    SELECT 
        [Extent1].[ProducerName] AS [ProducerName], 
        [Extent1].[NomenCode] AS [NomenCode], 
        [Extent1].[ErrorCount] AS [ErrorCount]
        FROM (

    SELECT  
[vw_AllNomenLost].[ProducerName] AS [ProducerName], 

        [vw_AllNomenLost].[NomenCode] AS [NomenCode], 

        [vw_AllNomenLost].[ErrorCount] AS [ErrorCount]
    FROM [dbo].[vw_AllNomenLost] AS [vw_AllNomenLost]) AS [Extent1]
        WHERE ([Extent1].[ProducerName] = @p__linq__0) AND (@p__linq__0 IS NOT NULL)


    )  AS [Project1]
    ORDER BY [Project1].[ErrorCount] DESC

如果我执行

SELECT     TOP (10) *
FROM        vw_AllNomenLost
where ProducerName = @producer
Order by ErrorCount desc

在Management Studio中，我得到了正确的结果。但我的linq查询返回一些重复的行。

NomenCode   ErrorCount
31190RRAA00  11
31190RRAA00  11
31190RRAA00  11
31190RRAA00  11

怎么可能？我不明白。我做错了什么？非常感谢您的阅读和抱歉太久的问题。
