Python 之 pymysql增删改查Mysql数据库

表结构：

代码：

#Author Kang

import pymysql

#连接方法
conn = pymysql.connect(host='10.3.152.35',port=3306,user='kang',passwd='123456',db='test')

#创建当前游标
cursor = conn.cursor()

#effect_row 为结果行数
effect_row = cursor.execute("select * from student")

#打印当前游标语句查询的结果
print(cursor.fetchall())

#建立需要插入的数据
data = [
    ('MM',33),
    ('BearBear',4),
    ('KK',10)
]

#执行插入多条语句
cursor.executemany('insert into student(name,age) values(%s,%s)',data)

#执行插入单条带变量的语句
#data = cursor.execute("insert into user(username,age,department) values('{0}','{1}','{2}')".format(username,age,department))

#提交语句
conn.commit()

#执行更新语句
cursor.execute('update student set name="MK" where id = 1')

conn.commit()

#执行删除语句
cursor.execute('delete from student where name = "KK"')

conn.commit()

cursor.close()

conn.close()
