【MongoDB】一文带你快速掌握MongoDB文档插入和查询

from pymongo import MongoClient

# 连接到MongoDB
client = MongoClient('mongodb://localhost:27017/')
db = client['test_database']  # 选择数据库
collection = db['test_collection']  # 选择集合/表

# 插入文档
document = {
    'name': 'Alice',
    'age': 25,
    'address': {
        'street': '123 Fake St',
        'city': 'Faketown',
        'zipcode': '12345'
    },
    'phone': '555-5555'
}

# 插入单个文档
result = collection.insert_one(document)
print('Inserted document with _id:', result.inserted_id)

# 插入多个文档
documents = [
    {'name': 'Bob', 'age': 29},
    {'name': 'Charlie', 'age': 32}
]
results = collection.insert_many(documents)
print('Inserted documents with _ids:', results.inserted_ids)

# 查询文档
query = {'name': 'Alice'}
result = collection.find_one(query)
print('Found document:', result)

# 查询所有文档
for doc in collection.find():
    print('Found document:', doc)
