Question

I created a C# console application, and need to access my database.

var connectionString = "Data Source=MyServer;Integrated Security=True;Initial Catalog=MyDB;";

using (var connection = new SqlConnection(connectionString))
{
    connection.Open();
}

The .Open() gives an exception:

“Cannot open database “MyDB” requested by the login. The login failed.”

Could you please help me with this? Should I give some permission to my application? How can I do it on Windows 7?

Answer 1

If you’re using Windows auth you shouldn’t need a user name and password (your login to Windows is sufficient, assuming it has permissions on the database). Otherwise you’ll need a username and password for the db.

Also, I’m not sure it matters, but always a good idea to run your application as admin when you have permissions issues.
