MongoDB语法

MongoDB客户端：
1，NoSQL Manager for MongoDB
2，Robomongo(推荐，好多教程上的语句能够直接使用)
不一样的客户端执行语句有差别

 参考：https://docs.mongodb.com/manual/reference/operator/aggregation/count/

一，NoSQL Manager for MongoDB客户端语句

1，id查询使用ObjectId

2，时间查询使用ISODate

{
  "_id" : ObjectId("5b498fb070bb993b335ab1c0"),
  "_class" : "com.onloon.custom.data.model.importdata.DetectiveTask",
  "keywords" : "pear",
  "status" : 0,
  "userId" : "645a828883714b679dc5d004e93dc192",
  "serverLevel" : "1",
  "createDate" : "20180714",
  "createTime" : ISODate("2018-07-14T05:52:48.584Z"),
  "updateTime" : ISODate("2018-07-14T05:52:48.584Z"),
  "countries" : "Russia&&United Kingdom"
}

 

{"userId":"645a828883714b679dc5d004e93dc192", "_id" : ObjectId("5b498fb070bb993b335ab1c0"),"createTime" : {$gte : ISODate("2018-07-14T05:52:48.584Z")}}

　　

二，Robomongo客户端

1，SUM

按照productType统计pv的总和：

{
"_id" : ObjectId("598bb71370bb9933cf6fa196"),
"_class" : "com.onloon.website.analytics.core.entity.ProductTrafficBean",
"productId" : "83277ed6be2f4e46b6fbdc6866416e94",
"platform" : 0,
"shopId" : "151623511167744942",
"pv" : NumberLong(3),
"uv" : NumberLong(1),
"uvTime" : NumberLong(252186),
"msgProductCount" : 2,
"date" : "2017-08-10",
"productType" : "1",
"cookie" : ""
}

db.getCollection('doc_product_traffic').aggregate([{$group : {_id : "$productType", num_tutorial : {$sum : "$pv"}}}])

按照pageType统计总数：

{
"_id" : ObjectId("5a7d975c01c56936f40d1f27"),
"_class" : "com.onloon.website.analytics.core.entity.PageDirectBean",
"pageId" : "aa123a",
"pageType" : 2,
"redirectUrl" : "www.baidu.com"
}

db.getCollection('pageDirectBean').aggregate([{$group : {_id : "$pageType", num_tutorial : {$sum : 1}}}])

 2，COUNT

{“_ id”：ObjectId（“54936 ... dd0c”），“last_name”：“smith”，“first_name”：“mike”} 
{“_ id”：ObjectId（“54936 ... dd0d”），“last_name”：“smith “，”first_name“：”william“} 
{”_ id“：ObjectId（”54936 ... dd0e“），”last_name“：”smith“，”first_name“：”william“} 
{”_ id“：ObjectId（”54936 ... dd0f“），”last_name“：”smith“，”first_name“：”mark“}

> db.collection.find（{“last_name”：“smith”}）.count（）;> db.collection.distinct（“first_name”，{“last_name”：“smith”}）.length;

 独立站点总IP数:

{
    "_id" : ObjectId("595dada070bb99301b45695a"),
    "_class" : "com.onloon.website.analytics.core.entity.PageViewLogBean",
    "domain" : "baidu.com",
    "url" : "dsds",
    "pageTitle" : "商品详情",
    "pageId" : "3232",
    "cookie" : "aba7981f-332a-421a-8a56-82095ddad5dd",
    "viewDate" : NumberLong(1499311520843),
    "viewFrom" : "0",
    "shopId" : "3232",
    "ip" : "223.93.170.250",
    "platform" : 0,
    "date" : "2017-07-06"
}

db.getCollection('doc_page_view_log').aggregate([{$match:{viewDate:{$lt:1532016000000}}},{$group: {_id: '$ip'} },{$count:"ipcount"}])

侦探次数:

{
    "_id" : ObjectId("5acf4e0170bb9918956ce28d"),
    "_class" : "com.onloon.custom.data.model.importdata.DetectiveTask",
    "keywords" : "phone",
    "status" : 0,
    "userId" : "83fcb7323c9a47de98403be7cedb9433",
    "serverLevel" : "1",
    "createDate" : "20180412",
    "createTime" : ISODate("2018-04-12T12:16:01.885Z"),
    "updateTime" : ISODate("2018-04-12T12:16:01.885Z")
}

db.getCollection('detectiveTask').count({"createTime" : {$lte : ISODate("2018-07-20T00:00:00.584Z")}})
