Operate the database

import pymysql

# 1.打开数据库连接(地址，账号，密码，数据库)
conn = pymysql.connect('localhost', 'root', '123456', 'mydb')
# 2.创建一个游标对象
cursor = conn.cursor()
# 3.插入一行记录，注意MySQL的占位符是%s
cursor.execute('insert into user (age, name, create_time, birthday) values (%s, %s, %s, %s)', [21, 'xiao', '2019-11-25 15:33:59', '2019-11-25'])
# 提交事务
conn.commit()

# 执行查询
cursor.execute('select * from user')
# 查询得到结果集
values = cursor.fetchall()
# 遍历结果集
for v in values:
    print('查询结果：', v)
# 1.关闭游标
cursor.close()
# 2.关闭连接
conn.close()
