MongoDB-从startDate到endDate获取数据

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"
  }

我正试图从我的mongo shell中进行查询，以获取2016年7月30日至2016年8月1日的数据

我使用的是：
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。如何解决此问题？

Answer 1

给定日期范围为"2016年7月30日"到"2016年8月1日"的输入，构造一些JS日期用于查询。通过除以1000:从日期中获得以秒为单位的时间戳（正如文档模式所暗示的）

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

样本输出

/* 1 */
{
    "_id" : ObjectId("579f04ccd8f31a5788eba0fb"),
    "uSN" : "100030001",
    "timestamp" : 1470009600,
    "timetag" : 1082016,
    "monthtag" : 82016,
    "hourtag" : 11,
    "mintag" : 10,
    "yeartag" : 2016,
    "id" : "d100030001_01082016_11_10"
}
/* 2 */
{
    "_id" : ObjectId("579f04ccd8f31a5788eba0fd"),
    "uSN" : "100030001",
    "timestamp" : 1469850900,
    "timetag" : 30072016,
    "monthtag" : 72016,
    "hourtag" : 10,
    "mintag" : 55,
    "yeartag" : 2016,
    "id" : "d100030001_30072016_10_55"
}

Answer 2

     Try This !!!

对于，

1.Monthtag：

db.dataProfTable.found（｛uSN:"100030001"，$和：[｛monthtag:｛$gte:72016｝｝，｛monthtag:｛$lte:82016｝〕｝）

2.时间戳：

db.dataProfTable.found（｛uSN:"100030001"，$和：[｛timestamp:｛$gte:1469836800｝｝，｛时间戳：｛$lte:147009600｝｝]｝）

Answer 3

要按时间戳查询，请使用以下内容：

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}}]})

要按时间标签查询，请使用以下内容：

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