执行 CLR 存储过程来运行 Cognos Report 时出现 System.IO.FileNotFoundException

早上好。我当前遇到一个 CLR 存储过程调用在 Visual Basic (VS 2008) 中创建的程序集的问题。在最高级别,程序集执行 Cognos8 中包含的报告并将输出移动到网络上的特定目录。从简单的测试 EXE 调用该方法时没有问题,但当我尝试通过 CLR 存储过程执行时,我收到以下信息:

Msg 6522,Level 16,State 1,Procedure ReportRunner,Line 0

A .NET Framework执行用户定义例程或聚合“ReportRunner”期间发生错误:

System.IO.FileNotFoundException:无法加载文件或程序集“cognosdotnet assembly_2_0” Version=10.1.4707.501、Culture=neutral、PublicKeyToken=d6e6d7d808b7e5b7' 或其依赖项之一。系统找不到指定的文件。 System.IO.FileNotFoundException:

) •cognosdotnet assembly_2_0 与“ReportRunner”程序集位于同一目录中 •cognosdotnet assembly_2_0 使用 CREATE ASSEMBLY 进行编目,权限集 = 不安全 •cognosdotnet assembly_2_0 也安装在GAC 中

以下是fuslogvw.exe 提供的消息:

Good Morning. I am currently experiencing an issue with a CLR Stored procedure calling an assembly created in Visual Basic (VS 2008). At the highest level, the assembly executes a report contained in Cognos8 and moves the output to a specificed directory on the network. I have no issue when calling the method from a simple test EXE, but when I try to execute via the CLR stored procedure, I am getting the following:

Msg 6522, Level 16, State 1, Procedure ReportRunner, Line 0

A .NET Framework error occurred during execution of user-defined routine or aggregate "ReportRunner":

System.IO.FileNotFoundException: Could not load file or assembly 'cognosdotnetassembly_2_0, Version=10.1.4707.501, Culture=neutral, PublicKeyToken=d6e6d7d808b7e5b7' or one of its dependencies. The system cannot find the file specified.

Notes
•cognosdotnetassembly_2_0 is located in the same directory as the "ReportRunner" assembly
•cognosdotnetassembly_2_0 was cataloged using CREATE ASSEMBLY with permission set = unsafe
•cognosdotnetassembly_2_0 is also installed in the GAC

The following is the message provided by fuslogvw.exe:

Can someone provide insight as to why SQL Server is unable to find cognosdotnetassembly_2_0?

Thanks for your assistance.

我知道这是不久前被问到的,但希望它能帮助将来的人,我将我所知道的包括在内。

这可能与 SQL CLR 系统内置的安全限制有关。我在尝试在 CLR SQL Sproc 内部使用 XML 序列化时遇到了问题,因为(您的错误日志也显示了这一点)XML 序列化实际上使用了反射,它比普通托管代码需要更多的安全权限。我猜您能够引用 Cognos 程序集,因为它是通过文件浏览添加的。如果您添加 GAC 的程序集,则列表非常有限,我确信它基于特定的接口或程序集属性,而您正在使用的 Cognos 程序集未实现或不提供该属性。

如果您的 CLR SQL 存储过程以更高的权限级别运行,它可能会起作用。很可能不会。

I know this was asked a while ago but in the hopes that it will help someone in the future I'm including what I know.

This is probably related to the Security restrictions that are built into the SQL CLR system. I had issues while trying to use XML Serialization inside of a CLR SQL Sproc, because (and your error log shows this as well) XML Serialization actually uses Reflection which requires more security permissions than normal managed code. I'm guessing you were able to reference the Cognos assembly because it was added via Browsing for the file. If you add a GAC'ed Assembly the list is very limited I'm sure it's based on a specific interface or assembly attribute, which isn't implemented or available in the Cognos Assembly you are using.

If your CLR SQL sproc runs with a higher permission level it might work. Most likely not.
