Result struct returned from any successful query. Its fields are:
* `command` - An atom of the query command, for example: `:select` or
`:insert`;
* `columns` - The column names;
* `rows` - The result set. A list of tuples, each tuple corresponding to a
row, each element in the tuple corresponds to a column;
* `num_rows` - The number of fetched or affected rows;
