Question

我有一个使用XRM SDK查询CRM的网站。在大多数情况下，我使用的是Query Expressions，但我在一个页面上进行聚合计数，因此，我正在使用Fetch XML查询。我在本地开发者机器上调试了网站，指向Dev CRM服务器没有任何问题。但是，如果我更新配置并指向我们的QA CRM，我会收到一般SQL错误。我使用诊断工具打开了跟踪，这是我在尝试执行fetch XML生成的SQL时看到的错误：

An error occurred in the Microsoft .NET Framework while trying to load assembly id 65536. The server may be running out of resources, or the assembly may not be trusted with PERMISSION_SET = EXTERNAL_ACCESS or UNSAFE. Run the query again, or check documentation to see how to solve the assembly trust issues. For more information about this error: 
System.IO.FileLoadException: Could not load file or assembly 'microsoft.crm.sqlclr.helper, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. An error relating to security occurred. (Exception from HRESULT: 0x8013150A)

我做了一些研究，我能找到的最好的东西是this KB article。但它适用于SQL Server 2005，而CRM则是SQL Server 2008.有谁知道如何解决此问题？

看起来这是QA数据库的权限问题。请参阅http://social.msdn.microsoft.com/Forums/en/sqlnetfx/thread/2465ac11-735c-4362-8da4-1ed672b0e261和http://crmpt.blogspot.de/2011/12/charts-aggregated-by-date-problem.html以供参考

从您的组织数据库的以下设置开始

ALTER DATABASE FOOBAR_MSCRM SET trustworthy ON
