对数据集“query”执行查询失败。
在尝试加载程序集 ID 65536 时 Microsoft .NET Framework 出错。服务器可能资源不足，或者不信任该程序集，因为它的 PERMISSION_SET 设置为 EXTERNAL_ACCESS 或 UNSAFE。请重新运行查询，或检查有关的文档了解如何解决程序集信任问题。有关此错误的详细信息: System.IO

这数据库是从其他数据库还原到本地数据库的，不少网友说在还原数据库之后,可以将数据库的OWNER设置成SA就可以解决
| 1 |
exec sp_changedbowner 'sa'
|
实际上并不能解决！
从报错信息可以看出，服务器不信任该程序集。将数据库的可信修改为true即可：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
1.exec sp_configure 'show advanced options', '1';
Go
reconfigure;
go
exec sp_configure 'clr enabled', '1'
go
reconfigure; --如果执行失败,就用这个RECONFIGURE WITH OVERRIDE;
exec sp_configure 'show advanced options', '1';
go
2.查SID在sys.databases 和sys.server_principals是否一致
SELECT * FROM sys.server_principals;
SELECT * FROM sys.sysdatabases ;
3.查看程序集是否存在
SELECT * FROM sys.assemblies;
SELECT * FROM sys.assembly_files;
4.修改为ON
ALTER DATABASE databasename SET TRUSTWORTHY on;
5.注意所有者
exec sp_changedbowner 'sa'
