通過T-SQL調用SMO？

Question

我想用SMO去做幾件在T-SQL中不容易做的事情。但是，我發現的所有示例都是針對C＃或Powershell的。有沒有簡單的方法通過T-SQL調用SMO，就像你可以用DMO和sp_OACreate一樣？其中一種方法是通過xp_cmdshell通過PowerShell調用SMO - 但這會很糟糕。建議？

一個明顯的例子是「通過SMO調用表格」。

謝謝。

不幸的是，SMO不能通過SQLCLR直接調用。它不僅僅是 - Microsoft.SqlServer.Smo.dll - 不在Supported .NET Framework Libraries列表中，但它被明確禁止。

如果您嘗試通過CREATE ASSEMBLY手動導入DLL，您會收到以下錯誤：

CREATE ASSEMBLY [SMO] 
AUTHORIZATION [dbo] 
FROM 
N'C:\Program Files\Microsoft SQL Server\110\SDK\Assemblies\Microsoft.SqlServer.Smo.dll' 
WITH PERMISSION_SET = UNSAFE; 

返回：

Msg 6596, Level 16, State 1, Line 1
CREATE ASSEMBLY failed because assembly 'Microsoft.SqlServer.Smo' is a system assembly. Consider creating a user assembly to wrap desired functionality.

好了，試試「創建用戶組裝包裝所需的功能」。

如果您的大會上標有PERMISSION_SET = SAFE你：

Msg 6522, Level 16, State 2, Line 1
A .NET Framework error occurred during execution of user-defined routine or aggregate "SmoTest":
System.Security.SecurityException: That assembly does not allow partially trusted callers.

如果您的大會上標有PERMISSION_SET = UNSAFE你：

Msg 6522, Level 16, State 2, Line 1
A .NET Framework error occurred during execution of user-defined routine or aggregate "SmoTest":
System.Exception: This functionality is disabled in the SQLCLR. It is recommended that you execute from your client application.
System.Exception:
at Microsoft.SqlServer.Management.Common.ConnectionManager..ctor()
at Microsoft.SqlServer.Management.Smo.Server..ctor()

UPDATE：

而且，我只是在2007年1月的MSDN論壇上發現了這個相關主題：

'microsoft.sqlserver.batchparser' is malformed or not a pure .NET assembly.
