linux下ads 怎么用

import sqlite3

# 连接到SQLite数据库（如果不存在则创建）
conn = sqlite3.connect('example.db')

# 创建一个游标对象
cursor = conn.cursor()

# 创建表
cursor.execute('''CREATE TABLE IF NOT EXISTS users (id INTEGER PRIMARY KEY, name TEXT)''')

# 插入数据
cursor.execute("INSERT INTO users (name) VALUES ('Alice')")
cursor.execute("INSERT INTO users (name) VALUES ('Bob')")

# 提交事务
conn.commit()

# 查询数据
cursor.execute("SELECT * FROM users")
rows = cursor.fetchall()
for row in rows:
    print(row)

# 关闭连接
conn.close()

import redis

# 连接到Redis服务器
r = redis.Redis(host='localhost', port=6379, db=0)

# 设置键值对
r.set('name', 'Alice')

# 获取键值对
name = r.get('name')
print(name.decode('utf-8'))

# 删除键值对
r.delete('name')

from pymongo import MongoClient

# 连接到MongoDB服务器
client = MongoClient('mongodb://localhost:27017/')

# 选择数据库和集合
db = client['mydatabase']
collection = db['users']

# 插入文档
user = {'name': 'Alice', 'age': 30}
collection.insert_one(user)

# 查询文档
users = collection.find({})
for user in users:
    print(user)

# 关闭连接
client.close()
