我的数据库中有类似的数据

 {
            _id: ObjectId(<some mongo default encoded id>),
        user: 45,
event_group: 1,
            events: [
            {event: "event name", current_points:1, date: ISO(2017-05-11 21:00:45.774Z)},
            {event: "event name1", current_points:2, date: ISO(2017-05-11 22:15:45.774Z)},
            {event: "event name2", current_points:5, date: ISO(2017-05-11 22:10:55.774Z)},
            {event: "event name3", current_points:8, date: ISO(2017-05-12 23:00:45.774Z)},
            {event: "event name4", current_points:10, date: ISO(2017-05-12 21:00:45.774Z)},
            {event: "event name5", current_points:25, date: ISO(2017-05-14 22:15:45.774Z)},
            {event: "event name6", current_points:20, date: ISO(2017-05-14 22:10:55.774Z)},
            ]
          }

{
            _id: ObjectId(<some mongo default encoded id>),
        user: 45,
event_group: 2,
            events: [
            {event: "event name", current_points:10, date: ISO(2017-05-11 21:00:45.774Z)},
            {event: "event name1", current_points:15, date: ISO(2017-05-11 22:15:45.774Z)},
            {event: "event name2", current_points:12, date: ISO(2017-05-11 22:10:55.774Z)},
            {event: "event name3", current_points:18, date: ISO(2017-05-12 23:00:45.774Z)},
            {event: "event name4", current_points:25, date: ISO(2017-05-12 21:00:45.774Z)},
            {event: "event name5", current_points:50, date: ISO(2017-05-14 22:15:45.774Z)},
            {event: "event name6", current_points:100, date: ISO(2017-05-14 22:10:55.774Z)},
            ]
          }

{
            _id: ObjectId(<some mongo default encoded id>),
        user: 44,
event_group: 1,
            events: [
            {event: "event name", current_points:20, date: ISO(2017-05-11 21:00:45.774Z)},
            {event: "event name1", current_points:15, date: ISO(2017-05-11 22:15:45.774Z)},
            {event: "event name2", current_points:30, date: ISO(2017-05-11 22:10:55.774Z)},
            {event: "event name3", current_points:35, date: ISO(2017-05-12 23:00:45.774Z)},
            {event: "event name4", current_points:45, date: ISO(2017-05-12 21:00:45.774Z)},
            {event: "event name5", current_points:100, date: ISO(2017-05-14 22:15:45.774Z)},
            {event: "event name6", current_points:120, date: ISO(2017-05-14 22:10:55.774Z)},
            ]
          }

我想在7天，15天，30天或更长时间内获取记录。我需要获取所有日期（每天）的用户记录。目前我正在使用以下查询获取它们：

db.Collection.aggregate(
{"$match":{"user":181}},{"$unwind":"$events"},{"$match":{"events.date":{"$gte":{"sec":1523471400,"usec":0},"$lte":{"sec":1523557799,"usec":0}}}},{"$sort":{"events.date":1}},{"$group":{"_id":null,,"points":{"$last":"$events.current_points"}}});

它获取1个日期范围的记录，我运行此查询7,15,30或更多次。查询和数据运行良好，但它在我的服务器上添加了更多处理。我想将这个查询添加到一个单一查询中，就像这样。以下是7天内提取记录的查询。

感谢您解决我的查询Vince Bowdren中的错误。这是我更新的查询。

如何通过我从中获取此数据的日期对此结果进行分组。例如，如果日期介于2017-05-23 00:00:00＆amp; 2017-05-23 23:59:59然后，结果也应该通过这个日期分组。

我需要获取所有这些数据，以便通过日期在图表中绘制它们。

db.getCollection('Collection').aggregate(
{"$match":{"user":121}},
{"$unwind":"$events"},
{"$match":{"$or":[
    {"events.date":{"$gte":{"sec":1522780200,"usec":0},"$lte":{"sec":1522866599,"usec":0}}},
    {"events.date":{"$gte":{"sec":1522866600,"usec":0},"$lte":{"sec":1522952999,"usec":0}}},
    {"events.date":{"$gte":{"sec":1522953000,"usec":0},"$lte":{"sec":1523039399,"usec":0}}},
    {"events.date":{"$gte":{"sec":1523039400,"usec":0},"$lte":{"sec":1523125799,"usec":0}}},
    {"events.date":{"$gte":{"sec":1523125800,"usec":0},"$lte":{"sec":1523212199,"usec":0}}},
    {"events.date":{"$gte":{"sec":1523212200,"usec":0},"$lte":{"sec":1523298599,"usec":0}}},
    {"events.date":{"$gte":{"sec":1523298600,"usec":0},"$lte":{"sec":1523384999,"usec":0}}},
    {"events.date":{"$gte":{"sec":1523385000,"usec":0},"$lte":{"sec":1523471399,"usec":0}}},
    {"events.date":{"$gte":{"sec":1523471400,"usec":0},"$lte":{"sec":1523557799,"usec":0}}},
    {"events.date":{"$gte":{"sec":1523557800,"usec":0},"$lte":{"sec":1523644199,"usec":0}}},
    {"events.date":{"$gte":{"sec":1523644200,"usec":0},"$lte":{"sec":1523730599,"usec":0}}},
    {"events.date":{"$gte":{"sec":1523730600,"usec":0},"$lte":{"sec":1523816999,"usec":0}}},
    {"events.date":{"$gte":{"sec":1523817000,"usec":0},"$lte":{"sec":1523903399,"usec":0}}},
    {"events.date":{"$gte":{"sec":1523903400,"usec":0},"$lte":{"sec":1523989799,"usec":0}}},
    {"events.date":{"$gte":{"sec":1523989800,"usec":0},"$lte":{"sec":1524076199,"usec":0}}}
    ]}},
{"$sort":{"events.date":1}},
{"$group":{"_id":"$user","events":{"$push":"$events"},
    "points":{"$last":"$events.current_points"},   
    }
}
)

目前我收到了这个结果：

{
    "result": [{
        "_id": 121,
        "points": 42930,
        "events": [{
            "current_points": 41875,
            "won": 1,
            "date": {
                "sec": 1522780225,
                "usec": 237000
            },
            "event_name": "abc"
        }, {
            "current_points": 41875,
            "won": 1,
            "date": {
                "sec": 1522780225,
                "usec": 237000
            },
            "event_name": "absc"
        }, {
            "current_points": 41875,
            "won": 0,
            "date": {
                "sec": 1522780225,
                "usec": 237000
            },
            "event_name": "abcd"
        }]
    }]
}

这不是你应该如何在$match块内编写标准。编辑您的查询，使其看起来像这样：

{"$or":[
    {"sec":{"$gte":1523471400}},{"usec":{"$gte":0}},{"sec":{"$lte":1523557799}},{"usec":{"$lte":0}}
    ....... //other criteria to be added.
    ]
}

另请勿重复usec的条件检查。只需添加剩余的sec匹配条件条件。

答案 1 :(得分：0)

您错误地使用了$or conditional。

而不是：

{"$match":{"events.date":
  {"$or":[
    {"$gte":{"sec":1523471400,"usec":0},"$lte":{"sec":1523557799,"usec":0}},
    {"$gte":{"sec":1523557800,"usec":0},"$lte":{"sec":1523644199,"usec":0}},
    {"$gte":{"sec":1523644200,"usec":0},"$lte":{"sec":1523730599,"usec":0}},
    {"$gte":{"sec":1523730600,"usec":0},"$lte":{"sec":1523816999,"usec":0}},
    {"$gte":{"sec":1523817000,"usec":0},"$lte":{"sec":1523903399,"usec":0}},
    {"$gte":{"sec":1523903400,"usec":0},"$lte":{"sec":1523989799,"usec":0}},
    {"$gte":{"sec":1523989800,"usec":0},"$lte":{"sec":1524076199,"usec":0}}
    ]
  }
}},

$或需要一组独立查询，每个查询包括他们查询的字段。尝试将其更改为：

{"$match":{
  "$or":[
    {"events.date" : {"$gte":{"sec":1523471400,"usec":0},"$lte":{"sec":1523557799,"usec":0}}},
    {"events.date" : {"$gte":{"sec":1523557800,"usec":0},"$lte":{"sec":1523644199,"usec":0}}},
    {"events.date" : {"$gte":{"sec":1523644200,"usec":0},"$lte":{"sec":1523730599,"usec":0}}},
    {"events.date" : {"$gte":{"sec":1523730600,"usec":0},"$lte":{"sec":1523816999,"usec":0}}},
    {"events.date" : {"$gte":{"sec":1523817000,"usec":0},"$lte":{"sec":1523903399,"usec":0}}},
    {"events.date" : {"$gte":{"sec":1523903400,"usec":0},"$lte":{"sec":1523989799,"usec":0}}},
    {"events.date" : {"$gte":{"sec":1523989800,"usec":0},"$lte":{"sec":1524076199,"usec":0}}
    ]
  }
},
