我有一个这样的查询:
context.Diffusions.Where(x => x.ProgrammeId == programmeID).Include("Chaines").Include("Version").ToList();
生成的查询是:
SELECT
[Extent1].[Duree] AS [Duree],
[Extent1].[Id] AS [Id],
[Extent1].[ProgrammeId] AS [ProgrammeId],
[Extent1].[VersionId] AS [VersionId],
[Extent1].[ChaineId] AS [ChaineId],
[Extent1].[Debut] AS [Debut],
[Extent1].[Fin] AS [Fin],
[Extent1].[ReRun] AS [ReRun],
[Extent1].[DateModification] AS [DateModification],
[Extent1].[DateDiffusion] AS [DateDiffusion],
[Extent2].[Id] AS [Id1],
[Extent2].[Nom] AS [Nom],
[Extent2].[Code] AS [Code],
[Extent2].[Abreviation] AS [Abreviation],
[Extent3].[Id] AS [Id2],
[Extent3].[ProgrammeId] AS [ProgrammeId1],
[Extent3].[CleVersion] AS [CleVersion],
[Extent3].[Numero] AS [Numero],
[Extent3].[NumeroModification] AS [NumeroModification],
[Extent3].[VO] AS [VO],
[Extent3].[TitrePresse] AS [TitrePresse],
[Extent3].[Description] AS [Description],
[Extent3].[Remarque] AS [Remarque],
[Extent3].[SousTitre] AS [SousTitre],
[Extent3].[DureeTheorique] AS [DureeTheorique],
[Extent3].[Format] AS [Format],
[Extent3].[Interdit] AS [Interdit],
[Extent3].[LangueId] AS [LangueId],
[Extent3].[TypeCoteDiffusionId] AS [TypeCoteDiffusionId]
FROM [dbo].[Diffusion] AS [Extent1]
INNER JOIN [dbo].[Chaine] AS [Extent2] ON [Extent1].[ChaineId] = [Extent2].[Id]
INNER JOIN [dbo].[Version] AS [Extent3] ON [Extent1].[VersionId] = [Extent3].[Id]
WHERE [Extent1].[ProgrammeId] = 1926475
我的问题是表格有很多条目,它为每个条目进行内部连接,然后执行“WHERE”,因此需要 6 秒。
当我在没有包含的情况下进行查询时,它是即时的。我想要一个 linq 查询来执行“WHERE”,然后为返回的每一行执行“INCLUDE”,而不必为每个条目手动执行(一个程序可以有 1 000 个扩散)。
