Я получил sql-процедуру из CLR (.net Assembly), которая при выполнении возвращает ошибку
Msg 6522, Level 16, State 1, Procedure sp_HelloWorld, Line 0
A .NET Framework error occurred during execution of user defined routine or aggregate 'sp_HelloWorld':
System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
System.Security.SecurityException:

Это мой SQL-скрипт
go
drop procedure HelloWorld
drop assembly HelloWorld
GO
create assembly HelloWorld from 'F:\HelloWorld.dll'
with permission_set = safe
Go
create procedure sp_HelloWorld
as external name HelloWorld.[HelloWorld.SQLCLR].HelloWorld
go
exec sp_HelloWorld
а это мой класс (сборка)
using Microsoft.SqlServer.Server;
using System.Data.SqlTypes;
using System.Data.SqlClient;
using System.Security.Permissions;
using System.Data;
namespace HelloWorld
{
public class SQLCLR
{
[Microsoft.SqlServer.Server.SqlProcedure]
public static void HelloWorld()
{
string connectString1 = @"Data Source=localhost;Initial Catalog=ItemData;Integrated Security=True";
SqlClientPermission permission = new SqlClientPermission(PermissionState.None);
permission.Add(connectString1, "", KeyRestrictionBehavior.AllowOnly);
permission.PermitOnly();
SqlConnection sqlcon = new SqlConnection(connectString1);
sqlcon.Open();
SqlCommand sqlcmd = new SqlCommand("SELECT Top 1 * FROM ItemData.dbo.Item", sqlcon);
SqlDataReader reader = sqlcmd.ExecuteReader();
SqlContext.Pipe.Send(reader);
sqlcon.Close();
}
}
}
