使用插入數(shù)據(jù)命令：

>insert

需要注意的是，如果插入一文件（現(xiàn)在理解，nosql 類型的db數(shù)據(jù)不能說(shuō)是記錄了，它是已文件作為單位，而傳統(tǒng)型的關(guān)系型數(shù)據(jù)庫(kù)，我們說(shuō)是插入一條記錄），如果沒(méi)有帶人_id,那么會(huì)自動(dòng)生成一個(gè)唯一的id,這個(gè)id好比關(guān)系型數(shù)據(jù)庫(kù)里的主鍵一樣。

如果是自己指定id，那么必須id是唯一的，這點(diǎn)關(guān)系型和nosql型都必須要求的；

數(shù)據(jù)字段的名字不能包含$ 和.

在敲了一陣發(fā)現(xiàn)，擦，我要是再shell里面去編寫(xiě)復(fù)雜的插入語(yǔ)句，就shell的這種一行一句，不搞死我去啊。我想它肯定是支持向bat這種批處理或者其他，看它語(yǔ)法和js一模一樣，于是大膽猜測(cè)它使用的就是javascript,于是我就用notepad++來(lái)編輯這些插入命令，試著插入復(fù)雜的對(duì)象；

哦，另外說(shuō)一句，如果這個(gè)bios數(shù)據(jù)不存在，那么要先使用

>use bios

生成一個(gè)數(shù)據(jù)庫(kù)，如果你不往這里插入一筆數(shù)據(jù)，mongoDB會(huì)自動(dòng)刪除掉這個(gè)數(shù)據(jù)庫(kù)；

所以還要插入一筆讓mongodb維持這數(shù)據(jù)庫(kù)的任意數(shù)據(jù)

>db.bios.insert({a:'a'})

編寫(xiě)了一個(gè)insert.js腳步，放在安裝目錄的js文件夾下。于是這樣輸入：

>mongolocalhost:27017/bios f:mongodbjsinsert.js

效果如圖

可以看到，這個(gè)js腳步成功執(zhí)行；

要查詢這個(gè)文檔，輸入命令：

>db.bios.find({ name: { first: 'John', last: 'chen' } } );

有了js寫(xiě)更多的語(yǔ)句，就方便多了。

Isert語(yǔ)句支持多個(gè)批量插入就像下面這樣:

Insert.js 語(yǔ)句：
