    数据列有一字段是 "updatetime"， 里面都是 unix 时间戳
    普通的查询语句
    db.getCollection("mg_result_sorted_all").find({},
    {
    "login": 1,
    "updatetime":1
    })

    怎么返回类似"2018-05-04 12:00:00" 这样的数据呢？
  • updatetime
  • Unix
  • mongo
  • 2018-05-04

    mysql 就很简单了……
    直接 select 里套一个 time 格式化函数就好了… mongo 的不知道怎么做

    @yulitian888
    可能理解错意思了哦，
    不是查询时 where 里的条件，
    我想的是查询的时候可以把原始数据以"2018-05-04 12:00:00"这样的格式返回

    $aggregate 的 $group 里面的运算符应该可以满足需求，比如 $dateToString 之类的
    不过感觉没啥必要啊，可以查出来以后再做转换呀

    @knowckx 查出来再转就是了
    db.getCollection("mg_result_sorted_all").find({}).forEach(function (a) { /*这里转吧！*/ });
