我对以下查询有问题。它可以工作并提供所需的结果，但速度相当慢，因为我的子选择带有连接。我的TSQL技能不足以优化此查询。也许你们中的一些人可以帮忙

SELECT
    Id AS InstanceId,
    (SELECT COUNT(DISTINCT tiq.Id) AS Expr1
     FROM   dbo.tInputQueueEntry AS tiq INNER JOIN
            dbo.tProcessLog AS tpr ON tpr.InstanceConfigId = tic.Id AND tpr.InputQueueEntryId = tiq.Id
     WHERE  (tpr.ProcessResultId = 32)) AS Received,
    (SELECT COUNT(DISTINCT tiq.Id) AS Expr1
     FROM   dbo.tInputQueueEntry AS tiq INNER JOIN
            dbo.tProcessLog AS tpr ON tpr.InstanceConfigId = tic.Id AND tpr.InputQueueEntryId = tiq.Id
     WHERE        (tiq.InMsgStateFlags = 1)) AS Queued,
    (SELECT COUNT(DISTINCT tiq.Id) AS Expr1

            dbo.tProcessLog AS tpr ON tpr.InstanceConfigId = tic.Id AND tpr.InputQueueEntryId = tiq.Id
     WHERE  (tiq.InMsgStateFlags = 256)) AS Rejected,
    (SELECT COUNT(tiq.Id) AS Expr1

此查询作为视图运行

如果你需要进一步的信息，请告诉我

这是表格信息

tProcessLog

    [Id] [bigint] IDENTITY(1,1) NOT NULL,
[InstanceConfigId] [int] NOT NULL,
[InputQueueEntryId] [bigint] NOT NULL,
[OutputQueueEntryId] [bigint] NULL,
[ProcessingDtm] [datetime] NOT NULL,
[ProcessResultId] [int] NOT NULL,
[SeverityId] [int] NOT NULL,
[LogText] [varchar](max) NOT NULL,
[IsHidden] [bit] NOT NULL,
[ReceiverId] [int] NOT NULL,

tInputQueueEntry

    [Id] [bigint] IDENTITY(1,1) NOT NULL,
[Created] [datetime] NOT NULL,
[DataTypeId] [int] NOT NULL,
[CodePage] [int] NOT NULL,
[InMsgStateFlags] [int] NOT NULL,
[ContentData] [nvarchar](max) NOT NULL,
[ContentHash] [nvarchar](32) NOT NULL,

罐头盒

[IsActive] [bit] NOT NULL,
[Type] [varchar](50) NOT NULL,
[Description] [varchar](50) NOT NULL,
[ComponentConfig] [xml] NOT NULL,
[InstanceGroupId] [int] NOT NULL,

更新

最后，我认为没有办法获得更高的性能。我使用了MSSQL调优顾问，它提供了一些建议，现在查询速度达到500毫秒。对我来说没关系

感谢所有的答案！我没有帮助解决性能问题，但我学到了很酷的tsql新东西：）
