插入資料:

MongoDB使用insertOne函數插入一條資料

如:

1.先用document指定插入的資料:

document = ({"Type":"Book","Title":"Definitive Guide to MongoDB 3rd ed.","ISBN":"978-1-4842-1183-0","Publisher":"Apress","Author":    ["Hows,David","Plugge,Eelco","Membrey,Peter","Hawkins,Tim"]})

系統返回

{
"Type" : "Book",
"Title" : "Definitive Guide to MongoDB 3rd ed.",
"ISBN" : "978-1-4842-1183-0",
"Publisher" : "Apress",
"Author" : [
"Hows,David",
"Plugge,Eelco",
"Membrey,Peter",
"Hawkins,Tim"
]
}

2.執行插入操作:

db.media.insertOne(document)

系統返回:

{
"acknowledged" : true,
"insertedId" : ObjectId("5aa47c1953350e04ddbd6fa3")
}

其中,insertedId是插入後形成的_id索引值,保證唯一性,它由4位時間戳記 3位機器id 2位進程id 3位計數器組成

 

還有一種方法直接通過shell插入資料

如:db.media.insertOne({"Type":"CD","Artist":"Nirvana","Title":"Nevermind","Tracklist":[{"Track":"1","Titie":"Smells Like Teen Spirit","Length":"5:02"},{"Track":"2","Title":"In Bloom","Length":"4:15"}]})

系統返回:

{
"acknowledged" : true,
"insertedId" : ObjectId("5aa47dd553350e04ddbd6fa4")
}
