#!/usr/bin/env python
# encoding=utf8
import MySQLdb

conn = MySQLdb.connect(host='127.0.0.1', user='root', passwd='123456', port=3306, charset='utf8')
try:
    cursor = conn.cursor()
    cursor.execute("drop database if exists tmpdb")
    cursor.execute("create database tmpdb")
    conn.select_db("tmpdb")
    cursor.execute("create table tmptab(c1 int, c2 varchar(20), c3 varchar(20)) ENGINE=InnoDB  DEFAULT CHARSET=utf8")
    cursor.execute(
        "insert into tmptab values(101, '姓名1', 'address1'), (102, '姓名2', 'address2'), (103, '姓名3', 'address3'), (104, '姓名4', 'address4')")
    conn.commit();  # 执z行commit后数据才能入库并可见
except:
    conn.rollback()
cursor.close()  # 关闭指针
conn.close()  # 关闭连接
