Python中对mysql数据库的操作

# 导入MySQL驱动:import mysql.connector# 注意把password设为你的root口令:conn = mysql.connector.connect(user='root', password='root', database='liumeng')cursor = conn.cursor()# 创建user表:cursor.execute('create table user (id varchar(20) primary key, name varchar(20))')# 插入一行记录，注意MySQL的占位符是%s:cursor.execute('insert into user (id, name) values (%s, %s)', ['1', 'Michael'])cursor.rowcount# 提交事务:conn.commit()cursor.close()# 运行查询:cursor = conn.cursor()cursor.execute('select * from user where id = %s', ('1',))values = cursor.fetchall()print(values)cursor.close()conn.close()
