1.MongoDB bin目錄介紹

　　mongo.exe：客戶端，支援js語法
　　mongod.exe：服務端
　　mongodump.exe：備份工具
　　mongorestore.exe：恢復工具
　　mongoexport.exe：匯出工具
　　mongoimport.exe：匯入工具
　　mongostat.exe：實時效能監控工具
　　mongotop.exe：跟蹤MongDB例項讀寫時間工具

2.mongo.exe操作資料庫

上節我們已經把mongodb裝為windos服務了，所以可以簡單啟動

D:\MongoDB\Server\3.2\bin>net start mongodb
請求的服務已經啟動。

請鍵入 NET HELPMSG 2182 以獲得更多的幫助。


D:\MongoDB\Server\3.2\bin>
 

我的已經啟動了，我們開啟客戶端，可能和我的不一樣，不過沒什麼關係，看到 connecting to:test 說明連線成功。因為是支援js的，我們輸入1+1 會輸出結果 2

3.MongoDB基本語法

檢視資料庫：show dbs

> show dbs
local  0.078GB
test   0.078GB
>

新建資料庫：use  表名（新建資料庫必須進行此庫相關的操作，否則不會建立）

> use first
switched to db first
> show dbs
local  0.078GB
test   0.078GB

插入資料：db.表名.insert(資料) 

> db.first.insert({name:"tom",age:"12"})
WriteResult({ "nInserted" : 1 })
> show dbs
first  0.078GB
local  0.078GB
test   0.078GB
>　
 

查詢表中的所有資料：db.表名.find()

> db.first.find()
{ "_id" : ObjectId("56fc8e6d58257d7101dfafa0"), "name" : "tom", "age" : "12" }
>

修改資料：db.表名.update({"條件欄位名":"欄位值"},{$set:{"要修改的欄位名":"修改後的欄位值"}});

> db.first.update({name:"tom"},{$set: {age:13}})
WriteResult({ "nMatched" : 1, "nUpserted" : 0, "nModified" : 0 })
> db.first.find()
{ "_id" : ObjectId("56fc8e6d58257d7101dfafa0"), "name" : "tom", "age" : 13 }
>

批量插入資料：

> for(var i=1;i<10;i++){db.first.insert({name:"tom"+i,age:i}); }
WriteResult({ "nInserted" : 1 })
> db.first.find()
{ "_id" : ObjectId("56fc8e6d58257d7101dfafa0"), "name" : "tom", "age" : 13 }
{ "_id" : ObjectId("56fc907858257d7101dfafa1"), "name" : "tom1", "age" : 1 }
{ "_id" : ObjectId("56fc907858257d7101dfafa2"), "name" : "tom2", "age" : 2 }
{ "_id" : ObjectId("56fc907858257d7101dfafa3"), "name" : "tom3", "age" : 3 }
{ "_id" : ObjectId("56fc907858257d7101dfafa4"), "name" : "tom4", "age" : 4 }
{ "_id" : ObjectId("56fc907858257d7101dfafa5"), "name" : "tom5", "age" : 5 }
{ "_id" : ObjectId("56fc907858257d7101dfafa6"), "name" : "tom6", "age" : 6 }
{ "_id" : ObjectId("56fc907858257d7101dfafa7"), "name" : "tom7", "age" : 7 }
{ "_id" : ObjectId("56fc907858257d7101dfafa8"), "name" : "tom8", "age" : 8 }
{ "_id" : ObjectId("56fc907858257d7101dfafa9"), "name" : "tom9", "age" : 9 }
>

按條件查詢（支援多條件）：db.表名.find(條件); 

> db.first.find({name:"tom1"})
{ "_id" : ObjectId("56fc907858257d7101dfafa1"), "name" : "tom1", "age" : 1 }
> db.first.find({"$or":[{name:"tom1"},{name:"tom2"}]})
{ "_id" : ObjectId("56fc907858257d7101dfafa1"), "name" : "tom1", "age" : 1 }
{ "_id" : ObjectId("56fc907858257d7101dfafa2"), "name" : "tom2", "age" : 2 }
>

刪除資料：db.表名.remove(條件)

> db.first.remove({name:"tom1"})
WriteResult({ "nRemoved" : 1 })
> db.first.find()
{ "_id" : ObjectId("56fc8e6d58257d7101dfafa0"), "name" : "tom", "age" : 13 }
{ "_id" : ObjectId("56fc907858257d7101dfafa2"), "name" : "tom2", "age" : 2 }
{ "_id" : ObjectId("56fc907858257d7101dfafa3"), "name" : "tom3", "age" : 3 }
{ "_id" : ObjectId("56fc907858257d7101dfafa4"), "name" : "tom4", "age" : 4 }
{ "_id" : ObjectId("56fc907858257d7101dfafa5"), "name" : "tom5", "age" : 5 }
{ "_id" : ObjectId("56fc907858257d7101dfafa6"), "name" : "tom6", "age" : 6 }
{ "_id" : ObjectId("56fc907858257d7101dfafa7"), "name" : "tom7", "age" : 7 }
{ "_id" : ObjectId("56fc907858257d7101dfafa8"), "name" : "tom8", "age" : 8 }
{ "_id" : ObjectId("56fc907858257d7101dfafa9"), "name" : "tom9", "age" : 9 }
>

檢視當前資料庫：db
切換資料庫：use 表名 刪除當前資料庫：db.dropDatabase()

> db
first
> use test
switched to db test
> db
test
> use first
switched to db first
> db.dropDatabase()
{ "dropped" : "first", "ok" : 1 }
> show dbs
local  0.078GB
test   0.078GB
>

介紹的應該能滿足基本操作，具體請看API

4.視覺化工具

是不是覺得控制檯寫程式碼太太太太難受了，所以我們需要一個視覺化工具 我用的是MongoBooster 安裝非常的簡單
