linq not in

linq not in 查询 or join not in

var query = from c in _opvRepository.Table
                        join a in _orderRepository.Table on c.OrderId equals a.Id join p in _pvRepository.Table on c.ProductVariantId equals p.Id join e in _productRepository.Table on p.ProductId equals e.Id where a.CustomerId == customerId & !(from s in _productReviewRepository.Table select s.ProductId).Contains(a.CustomerId & p.ProductId) select new CustomerChapter() { Name = p.Name, ProdcutName = e.Name, CreatedOn = a.CreatedOnUtc, ProductId = p.ProductId, Id = a.CustomerId, };

生成的sql 语句如下

SELECT 
[Filter2].[OrderId] AS [OrderId], 
[Filter2].[Name] AS [Name], [Extent4].[Name] AS [Name1], [Filter2].[CreatedOnUtc1] AS [CreatedOnUtc], [Filter2].[ProductId] AS [ProductId], [Filter2].[CustomerId] AS [CustomerId] FROM (SELECT [Extent1].[OrderId] AS [OrderId], [Extent2].[CustomerId] AS [CustomerId], [Extent2].[CreatedOnUtc] AS [CreatedOnUtc1], [Extent3].[ProductId] AS [ProductId], [Extent3].[Name] AS [Name] FROM [dbo].[OrderProductVariant] AS [Extent1] INNER JOIN [dbo].[Order] AS [Extent2] ON [Extent1].[OrderId] = [Extent2].[Id] INNER JOIN [dbo].[ProductVariant] AS [Extent3] ON [Extent1].[ProductVariantId] = [Extent3].[Id] WHERE NOT EXISTS (SELECT 1 AS [C1] FROM ( SELECT 1 AS X ) AS [SingleRowTable1] WHERE 1 = 0 ) ) AS [Filter2] INNER JOIN [dbo].[Product] AS [Extent4] ON [Filter2].[ProductId] = [Extent4].[Id] WHERE [Filter2].[CustomerId] = 1
