I wonder though what is the syntax if I wanted

as a "left outer join" as well?

you were using an implied join instead of an explicit one.

    select
        u.uid,
        /* u.pass, */
        f.filename as avatar,
        (g.field_gender_value='Female') as female,
        c.field_city_value as city
	from
          drupal_users u
            JOIN drupal_field_data_field_gender g ON g.entity_id=u.uid
            JOIN drupal_field_data_field_city c ON c.entity_id=u.uid
	    LEFT JOIN drupal_file_managed f ON u.picture=f.fid
    	where
          u.name='mvp';


is more like how you code a conventional JOIN.
