insert_one():spa
對一張不存在表插入數據,他會在插入數據同時自動生成數據表,code
例如我要對chat集合插入數據,插入一個空數據對象
import pymongo mongo_client = pymongo.MongoClient( host='192.168.0.112', port=27017, username="admin", password="123456" ) mongo_db = mongo_client["db1"] # 插入數據 res = mongo_db.chat.insert_one({}) print(res,res.inserted_id)
返回對象blog
<pymongo.results.InsertOneResult object at 0x0000000002EDBF08>
inserted_id 獲取插入的數據的_id ObjectIdclass
5cb0ba3abd99392b1427c25e
> db.chat.find() { "_id" : ObjectId("5cb0ba3abd99392b1427c25e") }
insert_many() :插入多條數據import
import pymongo mongo_client = pymongo.MongoClient( host='192.168.0.112', port=27017, username="admin", password="123456" ) mongo_db = mongo_client["db1"] # 插入數據 res = mongo_db.chat.insert_many( [ { 'name':"jack","age":13, }, { 'name':"mike","age":33, }, ] ) print(res,res.inserted_ids)
拿到對象cli
<pymongo.results.InsertManyResult object at 0x0000000002EDAF88>
inserted_ids 能夠返回多個插入的數據的 _id objectID
[ObjectId('5cb0bbf9bd993914d8b5d82c'), ObjectId('5cb0bbf9bd993914d8b5d82d')]
