sql-server - MSSQL加载程序集错误

Question

我在运行使用 MSSSQL 中的程序集的函数时收到以下错误:

Msg 10314, Level 16, State 11, Line 36 An error occurred in the Microsoft .NET Framework while trying to load assembly id 65800. 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 'exporttoexcel, Version=0.76.0.0, Culture=neutral, PublicKeyToken=f73371c9a1809a3f' or one of its dependencies. Exception from HRESULT: 0x80FC80F1 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)

但是在我重新创建函数和程序集之后，在一段时间内一切正常:

DROP FUNCTION [dbo].[fnExportToExcel]
DROP ASSEMBLY ExcelExporter

CREATE ASSEMBLY ExcelExporter  
AUTHORIZATION [DOMAIN\ACCOUNT]
FROM 'ExportToExcel.dll'
WITH PERMISSION_SET = UNSAFE

CREATE FUNCTION [dbo].[fnExportToExcel](@Query [nvarchar](max), @FilePath [nvarchar](max), @FileName [nvarchar](max), @SheetNames [nvarchar](max))
RETURNS [nvarchar](max) WITH EXECUTE AS CALLER
AS 
EXTERNAL NAME ExcelExporter.[ExportToExcel_DLL.cls_ExcelExport].[ExportToExcel]
GO

有什么想法可能导致 MSSQL 丢失程序集引用吗？

就我而言，运行此命令解决了问题:

EXEC sp_changedbowner 'sa'
