谁在执行这个特定的查询？
Who is executing this particular query?
正在寻找有关以下查询来源的帮助。此查询对我们的 DynamicsAX 数据库每 5 分钟执行一次，平均执行时间为 25 秒。我知道它来自我们的 SSRS 服务器，它也托管我们的 ManagementReporter 数据库，我找不到可以执行它的工作，因此我怀疑它来自某种应用程序。
我想看看是否可以提高性能。从统计数据来看，modelSecurityRole 和 SubRole 是重中之重。
假设这不是用户生成的查询，这个执行时间是课程的标准时间，还是我们可以优化的？

我使用的是 SQL 2012
的最新版本
这些查询是从 Management Reporter 生成的，您无法更改它们。您可以在 AOT 中为 [MicrosoftDynamicsAX] 数据库中的表添加索引，但不能为 [MicrosoftDynamicsAX_Model] 数据库中的表添加索引。
这意味着您的调整选项非常有限，而且我不止一次看到此查询需要花费数秒的时间，但 IO 量对我来说似乎不合适。
虽然我想到了一些事情：
确保您的统计数据是最新的，并且您的索引也针对模型数据库进行了碎片整理。您可以使用定期维护计划、SQL 语句或 Optimize-AXModelStore.
来执行此操作
确保您的 Management Reporter 是最新的 CU（Management Reporter 有它自己的 CU，与 AX 分开），他们的修复并不总是记录得很好，但他们可能已经更改了这个查询。
您没有使用 SQL 2014，但无论如何我都会在此处添加此信息以供将来的读者使用。我在 SQL 2014 年的 new Cardinality Estimator 中多次看到此查询行为不当。因此，对于使用 SQL 2014 的用户，请确保您的 SQL 服务器已更新至最新的 CU，因为自 RTM 版本以来已发布了许多修复程序。如果您仍然无法让查询在 SQL 2014 上运行（这对我来说已经发生过几次），您可以通过创建计划指南添加 [=13= 来恢复此查询以使用旧的基数估计器] 像这样：
EXEC sp_create_plan_guide @name = N'[Management Reporter guide]', @stmt = N'<the exact text of the query, whitespace and linebreaks included>', @hints = N' OPTION(QUERYTRACEON 9481)'

虽然 2014 年问题的症状不是您描述的那样，但它 运行 几分钟并消耗了大量 CPU。
