Entity framework OData生成了错误的URL，还是只是我使用了错误的关键字

我有一个这样的疑问

https://example.com/_vti_bin/exampleService/exampleService.svc/Categories?
$filter=Products/any(x:x/Status eq toupper('DELETED'))&
$select=ID,Products/Status,Products/Title&
$expand=Products

exec sp_executesql N'SELECT 
    [Project2].[C1] AS [C1], 
    [Project2].[C2] AS [C2], 
    [Project2].[C3] AS [C3], 
    [Project2].[ID] AS [ID], 
    [Project2].[C4] AS [C4], 
    [Project2].[C5] AS [C5], 
    [Project2].[C8] AS [C6], 
    [Project2].[ID1] AS [ID1], 
    [Project2].[C6] AS [C7], 
    [Project2].[C7] AS [C8], 
    [Project2].[Title] AS [Title], 
    [Project2].[Status] AS [Status]
    FROM ( SELECT 
        [Extent1].[ID] AS [ID], 
        1 AS [C1], 
        N''DataAccess.Product'' AS [C2], 
        N''ID'' AS [C3], 
        N''Products'' AS [C4], 
        N'''' AS [C5], 
        [Extent2].[ID] AS [ID1], 
        [Extent2].[Title] AS [Title], 
        [Extent2].[Status] AS [Status], 
        CASE WHEN ([Extent2].[ID] IS NULL) THEN CAST(NULL AS varchar(1)) ELSE N''DataAccess.Product'' END AS [C6], 
        CASE WHEN ([Extent2].[ID] IS NULL) THEN CAST(NULL AS varchar(1)) ELSE N''Title,Status,ID'' END AS [C7], 
        CASE WHEN ([Extent2].[ID] IS NULL) THEN CAST(NULL AS int) ELSE 1 END AS [C8]
        FROM  [dbo].[Categories] AS [Extent1]
        LEFT OUTER JOIN [dbo].[Products] AS [Extent2] ON [Extent1].[ID] = [Extent2].[ProductID]
        WHERE ([Extent1].[ClientID] = @p__linq__0) AND ( EXISTS (SELECT 
            1 AS [C1]
            FROM [dbo].[Products] AS [Extent3]
            WHERE ([Extent1].[ID] = [Extent3].[ProductID]) AND (([Extent3].[Status] = (UPPER(N''DELETED''))) OR (([Extent3].[Status] IS NULL) AND (UPPER(N''DELETED'') IS NULL)))
        ))
    )  AS [Project2]
    ORDER BY [Project2].[ID] ASC, [Project2].[C8] ASC',N'@p__linq__0 int',@p__linq__0=23

但它不会根据status=deleted过滤数据集，并返回状态为not deleted的产品等

我查看了SQL跟踪，它生成了如下内容

https://example.com/_vti_bin/exampleService/exampleService.svc/Categories?
$filter=Products/any(x:x/Status eq toupper('DELETED'))&
$select=ID,Products/Status,Products/Title&
$expand=Products

exec sp_executesql N'SELECT 
    [Project2].[C1] AS [C1], 
    [Project2].[C2] AS [C2], 
    [Project2].[C3] AS [C3], 
    [Project2].[ID] AS [ID], 
    [Project2].[C4] AS [C4], 
    [Project2].[C5] AS [C5], 
    [Project2].[C8] AS [C6], 
    [Project2].[ID1] AS [ID1], 
    [Project2].[C6] AS [C7], 
    [Project2].[C7] AS [C8], 
    [Project2].[Title] AS [Title], 
    [Project2].[Status] AS [Status]
    FROM ( SELECT 
        [Extent1].[ID] AS [ID], 
        1 AS [C1], 
        N''DataAccess.Product'' AS [C2], 
        N''ID'' AS [C3], 
        N''Products'' AS [C4], 
        N'''' AS [C5], 
        [Extent2].[ID] AS [ID1], 
        [Extent2].[Title] AS [Title], 
        [Extent2].[Status] AS [Status], 
        CASE WHEN ([Extent2].[ID] IS NULL) THEN CAST(NULL AS varchar(1)) ELSE N''DataAccess.Product'' END AS [C6], 
        CASE WHEN ([Extent2].[ID] IS NULL) THEN CAST(NULL AS varchar(1)) ELSE N''Title,Status,ID'' END AS [C7], 
        CASE WHEN ([Extent2].[ID] IS NULL) THEN CAST(NULL AS int) ELSE 1 END AS [C8]
        FROM  [dbo].[Categories] AS [Extent1]
        LEFT OUTER JOIN [dbo].[Products] AS [Extent2] ON [Extent1].[ID] = [Extent2].[ProductID]
        WHERE ([Extent1].[ClientID] = @p__linq__0) AND ( EXISTS (SELECT 
            1 AS [C1]
            FROM [dbo].[Products] AS [Extent3]
            WHERE ([Extent1].[ID] = [Extent3].[ProductID]) AND (([Extent3].[Status] = (UPPER(N''DELETED''))) OR (([Extent3].[Status] IS NULL) AND (UPPER(N''DELETED'') IS NULL)))
        ))
    )  AS [Project2]
    ORDER BY [Project2].[ID] ASC, [Project2].[C8] ASC',N'@p__linq__0 int',@p__linq__0=23

如果我只想要状态为“已删除”的产品而不想要其他产品，那么使用“eq”是否正确

我使用的是ODataV3，将WCF数据服务与EF一起使用，我相信问题出在查询中。 形成你所说的url类似于

// get me categories
https://example.com/_vti_bin/exampleService/exampleService.svc/Categories?

// where any product is deleted
$filter=Products/any(x:x/Status eq toupper('DELETED'))&

// return the category id, product status and title
$select=ID,Products/Status,Products/Title&
$expand=Products

换言之，您是根据已删除状态筛选类别，而不是其中的产品。 您可以添加第二个筛选器来处理产品筛选，并且仅返回类别及其筛选的产品集

试试这样吧

https://example.com/_vti_bin/exampleService/exampleService.svc/Categories?
$filter=Products/any(x:x/Status eq toupper('DELETED'))&
$select=ID,Products/Status,Products/Title&
$expand=Products/any(p:p/Status eq toupper('DELETED'))

根据您的情况，最好将查询转过来

https://example.com/_vti_bin/exampleService/exampleService.svc/Products?
$filter=Status eq toupper('DELETED')&
$select=Category/ID,Status,Title

。。。通过提取一组产品及其相关类别Id，您可以得到相同的结果，但可以直接在基本查询中筛选这些产品，而不是使用更复杂的子集合筛选器

正如聊天中所讨论的，这确实需要一个有效的OData模型，其中正确定义了产品和类别之间的关系。

您的意思是在

状态上使用
toupper
而不是
toupper（'DELETED'）
@Pierre LoupPagniez很抱歉我没抓住你？但是，即使我删除了“toupper”，结果也是一样的。我的意思是：我认为现在你正在将你的
状态
与
已删除
的大写版本进行比较，后者已经是大写了。例如，如果您的
状态
等于
已删除
，则比较将无效。我认为您需要在
Status
上将呼叫移动到
toupper
，就像
Products/any（x:toupper（x/Status）eq'DELETED'）
。虽然我不确定语法，但我没有任何方法来测试我写的内容，因此您可能需要稍微移动
toupper
。@Pierre LoupPagniez所有数据库记录都已使用大写字母哦，那么我不知道，抱歉。谢谢，我尝试过，但得到了这个错误-术语“产品（$filter=any（p:p/Status eq'DELETED'））'在$select或$EXPLAND表达式中无效。
