Question

我有以下错误消息：

Msg 10314, Level 16, State 11, Line 1
An error occurred in the Microsoft .NET Framework while trying to load assembly id 66007. 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 'powerstatregression, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)
System.IO.FileLoadException: 
    at System.Reflection.Assembly._nLoad(AssemblyName fileName, String codeBase, Evidence assemblySecurity, Assembly locationHint, StackCrawlMark& stackMark, Boolean throwOnFileNotFound, Boolean forIntrospection)
    at System.Reflection.Assembly.InternalLoad(AssemblyName assemblyRef, Evidence assemblySecurity, StackCrawlMark& stackMark, Boolean forIntrospection)
    at System.Reflection.Assembly.InternalLoad(String assemblyString, Evidence assemblySecurity, StackCrawlMark& stackMark, Boolean forIntrospection)
    at System.Reflection.Assembly.Load(String assemblyString)

我运行此代码，最后一行导致问题：

ALTER DATABASE dasolPSDev SET TRUSTWORTHY ON;
GO

CREATE ASSEMBLY PowerStatRegression
AUTHORIZATION [dbo]
from 'C:\SqlDlls\PowerStatRegression.dll'
WITH PERMISSION_SET = UNSAFE
GO

CREATE PROCEDURE [dbo].[SpCreatePowerStatCorr]

Answer 1

@chris您在项目中引用了哪些其他程序集？在自定义程序集之前，可能需要将一些其他程序集添加到sql server，这是导致该错误的原因。例如，如果您引用类似Newtonsoft的JSON解析，则需要在您的之前添加该程序集。

我在尝试加载一个针对x86（32位）构建的dll时遇到此错误 - 或者至少是一个非常类似的错误，但是Sql Server是x64。只有在尝试运行我注册的函数时才显示错误...注册时没有抱怨！

将构建更改为目标“任何CPU”并重新注册程序集对我有用。
