Python操作mongodb数据库的方法详解

>>import pymongo>>

#导入pymongo木块>>> import pymongo as p#连接mongodb>>> client =p.MongoClient('localhost',27017)#查看mongodb有多少数据库>>> client.database_names ()['liyue', 'local', 'test']#连接具体某个数据库>>> db1 =client.liyue>>> db2 =client.test#查看该数据库下所有集合>>> db2.collection_names ()['col', 'test']#for循环遍历查看集合中的文档：查看col集合中第2条数据。>>> for i in db2.col.find().limit(1).skip(1):    print(i){'interests': ['balls', 'basketball', 12.0], '_id': ObjectId('583bb6dc8fbf0aee1d9c94bf'), 'name': 'Tom', 'sex': 'girl'}#清空集合，删除集合中所有数据>>> db1.col.remove ({}){'ok': 1, 'n': 0}#查看是否清空成功查询>>> for i in db1.col.find():    print(i)#插入一个文档（一条数据）>>> db1.col.insert ({'name':"python接口测试","date":"today","age":"15","like":100})ObjectId('5840fa9bbbd6900a787ac386')#查看插入是否成功查询>>> for i in db1.col.find():    print(i){'name': 'python接口测试', 'age': '15', '_id': ObjectId('5840fa9bbbd6900a787ac386'), 'date': 'today', 'like': 100}#插入多个文档>>> documents =[{"name":"liy","age":"10"},{"name":"haha","age":"30"},{"name":"huhu","age":"20"}]>>> db1.col.insert(documents)[ObjectId('5840fb6bbbd6900a787ac387'), ObjectId('5840fb6bbbd6900a787ac388'), ObjectId('5840fb6bbbd6900a787ac389')]#查看插入的查询>>> for i in db1.col.find().limit(3).skip(1):    print(i){'age': '10', '_id': ObjectId('5840fb6bbbd6900a787ac387'), 'name': 'liy'}{'age': '30', '_id': ObjectId('5840fb6bbbd6900a787ac388'), 'name': 'haha'}{'age': '20', '_id': ObjectId('5840fb6bbbd6900a787ac389'), 'name': 'huhu'}#查看数据按and连接条件查询>>> for i in db1.col.find({"name":"liy","age":"10"}):    print(i){'age': '10', '_id': ObjectId('5840fb6bbbd6900a787ac387'), 'name': 'liy'}#查看数据以age字段倒序查询>>> for i in db1.col.find().sort([("age",-1)]):    print(i){'age': '30', '_id': ObjectId('5840fb6bbbd6900a787ac388'), 'name': 'haha'}{'age': '20', '_id': ObjectId('5840fb6bbbd6900a787ac389'), 'name': 'huhu'}{'age': '10', '_id': ObjectId('5840fb6bbbd6900a787ac387'), 'name': 'liy'}#更新已有文档数据>>> db1.col.update ({"name":"huhu"},{"$set":{"name":"dongdong"}}){'updatedExisting': True, 'ok': 1, 'nModified': 1, 'n': 1}>>> for i in db1.col.find({"name":"dongdong"}):    print(i){'age': '20', '_id': ObjectId('5840fb6bbbd6900a787ac389'), 'name': 'dongdong'}#按条件删除某条数据>>> db1.col.remove ({"name":"dongdong"}){'ok': 1, 'n': 1}>>> db1.col.find({"name":"dongdong"})<pymongo.cursor.Cursor object at 0x00000000045B6828>>>> for i in db1.col.find({"name":"dongdong"}):    print(i)
