Python操作MySQL基础使用

python 复制代码

import pymysql

# 链接数据库
conn = pymysql.connect(
    host='10.5.6.250',
    port=3306,
    user='root',
    password='********'
)

# 查看MySQL版本信息
print(conn.get_server_info())  # 5.5.27

# 获取到游标对象
cursor = conn.cursor()

# 选择数据库
conn.select_db("hanligang_data")

# 使用游标对象执行sql语句
sql = "select * from tstudent"
cursor.execute(sql)

# 获取查询结果
results: tuple = cursor.fetchall()
print(results)  # 结果是一个大元组，里面包含了每一行数据的小元组

for r in results:
    print(r)

conn.close()  # 关闭

查询结果（里面身份证为for循环生产的虚拟数据）：
