在Debian系统上,你可以使用Python的数据库驱动程序来连接和操作数据库。以下是一些常见的数据库及其对应的Python驱动程序:
MySQL: 使用mysql-connector-python或PyMySQL库。
安装:pip install mysql-connector-python 或 pip install pymysql
示例代码(使用mysql-connector-python):
import mysql.connector
connection = mysql.connector.connect(
host="localhost",
user="your_username",
password="your_password",
database="your_database"
)
cursor = connection.cursor()
cursor.execute("SELECT * FROM your_table")
result = cursor.fetchall()
for row in result:
print(row)
cursor.close()
connection.close()
PostgreSQL: 使用psycopg2库。
安装:pip install psycopg2 或 pip install psycopg2-binary
示例代码:
import psycopg2
connection = psycopg2.connect(
dbname="your_database",
user="your_username",
password="your_password",
host="localhost"
)
cursor = connection.cursor()
cursor.execute("SELECT * FROM your_table")
result = cursor.fetchall()
for row in result:
print(row)
cursor.close()
connection.close()
SQLite: 使用内置的sqlite3库。
示例代码:
import sqlite3
connection = sqlite3.connect("your_database.db")
cursor = connection.cursor()
cursor.execute("SELECT * FROM your_table")
result = cursor.fetchall()
for row in result:
print(row)
cursor.close()
connection.close()
MongoDB: 使用pymongo库。
安装:pip install pymongo
示例代码:
from pymongo import MongoClient
client = MongoClient("mongodb://your_username:your_password@localhost:27017/your_database")
db = client.your_database
collection = db.your_table
for document in collection.find():
print(document)
请根据你需要连接的数据库类型选择合适的驱动程序,并按照示例代码进行操作。记得替换示例代码中的your_username、your_password、your_database和your_table为实际的值。
