If I have code with nested objects like this do I need to use the nested using statements to make sure that both the SQLCommand and the SQLConnection objects are disposed of properly like shown below or am I ok if the code that instantiates the SQLCommand is within the outer using statement.

    using (SqlConnection conn = new SqlConnection(sqlConnString))
        {
            using (System.Data.SqlClient.SqlCommand cmd = new System.Data.SqlClient.SqlCommand())
            {
             cmd.CommandType = CommandType.Text;
             cmd.CommandText = cmdTextHere;
             conn.Open();

             cmd.Connection = conn;
             rowsAffected = cmd.ExecuteNonQuery();
            }

        }
