Question

所以，我在DB中有这样的JSON（我使用mongoDB）

{ 
    "uSN": "100030001",
    "timestamp": 1470009600,
    "timetag": 1082016,
    "monthtag": 82016,
    "hourtag": 11,
    "mintag": 10,
    "yeartag": 2016, 
    "id": "d100030001_01082016_11_10"
  },
  { 
    "uSN": "100030001",
    "timestamp": 1470096000,
    "timetag": 2082016,
    "monthtag": 82016,
    "hourtag": 11,
    "mintag": 10,
    "yeartag": 2016, 
    "id": "d100030001_02082016_11_10"
  },
  { 
    "uSN": "100030001",
    "timestamp": 1469850900,
    "timetag": 30072016,
    "monthtag": 72016,
    "hourtag": 10,
    "mintag": 55,
    "yeartag": 2016, 
    "id": "d100030001_30072016_10_55"
  },
  { 
    "uSN": "100030001",
    "timestamp": 1469923200,
    "timetag": 31072016,
    "monthtag": 72016,
    "hourtag": 11,
    "mintag": 10,
    "yeartag": 2016, 
    "id": "d100030001_31072016_11_10"
  },
  { 
    "uSN": "100030001",
    "timestamp": 1469577600,
    "timetag": 27072016,
    "monthtag": 72016,
    "hourtag": 11,
    "mintag": 10,
    "yeartag": 2016, 
    "id": "d100030001_27072016_11_10"
  }

我正在尝试从我的mongo shell进行查询以获取数据从2016年7月30日到2016年8月1日。

我正在使用这个：
db.dataProfTable.find({ uSN: '100030001', timestamp : {'$gte': new Date(1469836800), '$lte': new Date(1470009600)})
和db.dataProfTable.find({'uSN': '100030001', 'timetag': {$gte: '30072016', $lt: '01082016'}})

但它不起作用。我该如何解决这个问题？

Answer 1

将输入作为日期范围＆＃34; 30-07-2016＆＃34;到＆＃34; 01-08-2016＆＃34;，构建一些在您的查询中使用的JS日期。以秒为单位获取时间戳（如文档架构所示），除以1000：

var start = new Date("2016-07-30")/1000,
    end = new Date("2016-08-01")/1000;
db.dataProfTable.find({
    "timestamp": { "$gte": start, "$lte": end }
})

示例输出

/* 1 */
{
    "_id" : ObjectId("579f04ccd8f31a5788eba0fb"),
    "uSN" : "100030001",
    "timestamp" : 1470009600,
    "timetag" : 1082016,
    "monthtag" : 82016,
    "hourtag" : 11,
    "mintag" : 10,
    "yeartag" : 2016,
    "id" : "d100030001_01082016_11_10"
}

/* 2 */

    "timetag" : 30072016,
    "monthtag" : 72016,
    "hourtag" : 10,
    "mintag" : 55,
    "yeartag" : 2016,

}

     Try This !!!

有关，

1. Monthtag ：

db.dataProfTable.find（{uSN：'100030001'，$和：[{monthtag：{$ gte： 72016}}，{monthtag：{$ lte：82016}}]}）

2. 时间戳：

db.dataProfTable.find（{uSN：'100030001'，$和：[{timestamp：{$ gte： 1469836800}}，{timestamp：{$ lte：1470009600}}]}）

Answer 3

按下面的时间戳使用查询：

var start = new Date("07/30/2016").getTime()/1000 //Date Format:mm/dd/yyyy. Doing by 1000 since u stored in seconds
var end = new Date("08/01/2016").getTime()/1000
db.dataProfTable.find({ uSN: '100030001', $and:[ {timestamp : {$gte:start}},{timestamp : {$lte: end}}]})

通过以下时间标签查询：

db.dataProfTable.find({'uSN': '100030001', 'timetag': {$gte: 30072016, $lt: 01082016}}) // Since u stored as number for timetag

MongoDB - 从startDate获取数据到endDate
