【问题描述】：
我有一个使用 XRM SDK 查询 CRM 的网站。在大多数情况下，我使用的是查询表达式，但我在一页上进行汇总计数，因此，我使用的是 Fetch XML 查询。我已经在本地开发人员机器上调试了网站，指向 Dev CRM 服务器没有任何问题。但是，如果我更新我的配置并指向我们的 QA CRM，我会收到一个通用的 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。但它是针对 SQL Server 2005 的，而 CRM 是 SQL Server 2008。有人知道如何解决这个问题吗？
【问题讨论】：
-
您要运行什么查询？您是否检查了数据库中 qa 机器上的用户权限？可能是证书问题？
-
@GregOks 这是对两个具有左外连接的表的聚合查询...您建议我检查哪些用户权限？
