查看不执行，但直接运行相同的查询答案

【问题标题】：View doesn't perform, but running the same query directly does查看不执行，但直接运行相同的查询
【发布时间】：2020-01-08 13:30:57
【问题描述】：

对于 PowerBI 使用情况，我们可以查看我们最大的表格。但是，它不会运行，会因 PAGEIOLATCH_SH 而超时。查询很简单：

select * from view where ProgramId = 'ParticularProgram'

但是，如果我们在视图中运行查询，它不会出现任何问题或超时。你知道是什么原因造成的吗？视图中的原始查询是：

select column 1, column 2 etc from table where ProgramId = 'ParticularProgram'

为分区指定 where 子句不会改变行为并使其保持缓慢。当两者一起运行时，第一个的查询成本为 99%。 ProgramId 在表中进行了分区，并且此特定程序是该分区的一部分。

在此先感谢

请为正在运行的查询找到附加的实际查询计划： DirectQueryOnTable，XML DirextQueryExecutionPlanXML 和对应的ddl：

此外，我添加了超时概述：LogOfWaitType

【问题讨论】：

您好，欢迎来到 Stack Overflow。就目前而言，我们只能猜测 - 请发布架构定义（对于您的基表和您的视图），以及两个查询的执行计划。
嗨！谢谢您的回答。我添加了一些信息，并且还想添加架构定义。您是指视图中使用的表结构和查询吗？还是您的意思不同？
您是否在查询中使用任何窗口函数？
我们非常更喜欢文字而不是图片，如果可以的话！是的，表格和视图的 DDL 会很棒。
@Bonzay，我现在包含了 DDL。该视图不包含任何窗口函数，只有 2 个鞋面。据我所知，这不会影响性能。

【解决方案1】：

视图首先扫描基表，然后应用由分区键组成的过滤器。因此极端的性能差异。执行计划完全不同。由于您没有在视图中执行任何操作，并且只选择了一些基表字段，因此我建议您删除视图并直接使用该表。另一种选择是 TVF：

    RETURNS TABLE

    )
    GO

然后使用 :

运行它

SELECT *
FROM dbo.fn_MyWorkaround('ParticularProgram')

这将为您提供相同的执行时间。

【讨论】：

确实看起来像视图中的扫描和排序步骤导致了问题。我们确实会开始直接在表上查询，以防止这种情况发生，因为视图的主要功能是在名称中添加空格，我们现在将转移到 PowerBI。感谢您的帮助！

【解决方案2】：

我能看到的两个问题：

ProgramId 上没有索引，所以连表查询都很慢。
视图查询实际上等价于...where upper(ProgramId) = 'ParticularProgram'，所以即使ProgramId上的索引确实存在，也不能直接使用。另请参阅：sargable。

建议：

索引ProgramId（这也应该加快表查询）。
修改视图以包含ProgramId AS [Program Id Original]，然后查询那个（假设您在使用区分大小写的排序规则时实际上不需要不区分大小写）：

select * from view where [Program Id Original] = 'ParticularProgram'

或者，在upper(ProgramId) 上创建一个功能索引。

另外，请考虑使用不区分大小写的排序规则，因此您无需在 WHERE 子句中使用 upper。
