插入时需要进行commit确认

from pymysql import Connection


conn = Connection(
    host="localhost",   #主机名(ip)
    port=3306,          #端口
    user="root",        #sql账户
    password='123321'     #密码
)

cursor =  conn.cursor()  #获取游标对象
conn.select_db("student")
#执行sql插入数据
cursor.execute("insert into student value (1001, '李晨', 20)")
#要进行数据更改要进行确认
conn.commit()

conn.close()

自动提交无需手动commit

from pymysql import Connection


conn = Connection(
    host="localhost",   #主机名(ip)
    port=3306,          #端口
    user="root",        #sql账户
    password='123321',  #密码
    autocommit = True   #在构建链接对象的时候可以设置自动的commit的 属性
)

cursor =  conn.cursor()  #获取游标对象
conn.select_db("student")
#执行sql插入数据
cursor.execute("insert into student value (1001, '李晨', 20)")
cursor.execute("insert into student value (1002, '郑凯', 18)")
#要进行数据更改要进行确认


conn.close()
