跟踪从实体框架代码调用的查询

Question

实体框架中是否有办法跟踪或确定在代码中从何处调用临时查询？此查询来自 SQL Server 中的 Activity Monitor，但是我不知道它在我们的代码中来自哪里，我们有大量的调用。有没有办法轻松解决这个问题？

SELECT 
    CASE WHEN ( EXISTS (SELECT 
        1 AS [C1]
        FROM [Test].[DT] AS [Extent1]
        WHERE  EXISTS (SELECT 
            1 AS [C1]
            FROM  [Test].[D] AS [Extent2]
            INNER JOIN [Test].[ME] AS [Extent3] ON [Extent2].[EId] = [Extent3].[EId]
            WHERE ([Extent1].[DId] = [Extent2].[Id]) AND ([Extent3].[MId] = @p__linq__0)
        )
    )) THEN cast(1 as bit) ELSE cast(0 as bit) END AS [C1]
    FROM  ( SELECT 1 AS X ) AS [SingleRowTable1]

对于 EF Core，这是添加 Query Tags 功能的原因，或者您始终可以使用 logging。对于 EF6，您可以使用 logging and interception。
