笔记
１．knex.raw 处理特殊字段，根据 json 类型某个值进行排序

// training_area : {"city_id": 1, "area_id": 2}
//select * from reservation order by  training_area::Json ->> 'city_id' asc
knex('reservation').select('training_area').orderBy(knex.raw("training_area::json ->> 'city_id'"), 'desc')
    .then(data => console.log(data))
