execute(sql, opts={}) {|r| ...}

Execute the given `sql` on the server. If the :return option is present, its value should be a method symbol that is called on the TinyTds::Result object returned from executing the `sql`. The value of such a method is returned to the caller. Otherwise, if a block is given, it is yielded the result object. If no block is given and a :return is not present, `nil` is returned.
