1.下载并安装connector/python
A.下载mysql-connector-python-2.1.6-py2.7-winx64.msi，下载之后，根据提示安装即可
下载地址：https://dev.mysql.com/downloads/connector/python/
2.使用命令行往mysql中添加数据
A.进入数据库命令行操作界面，使用mysql -u USERNAME -p PASSWORD
B.数据库常用操作
show databases; # 显示所有数据库
create database t1; # 创建数据库t1
use database t1; #指定当前操作的数据库为t1
drop database t1; #删除数据库t1
注：操作数据库，可参考菜鸟教程http://www.runoob.com/mysql/mysql-tutorial.html
C.表中所有数据如下
3.使用python中的mysql.connector模块操作mysql
python代码
import mysql.connector
# mysql1.py
config = {
'host': '127.0.0.1',
'user': 'root',
'password': 'root',
'port': 3306,
'database': 'test',
'charset': 'utf8'
}
try:
cnn = mysql.connector.connect(**config)
except mysql.connector.Error as e:
print('connect fails!{}'.format(e))
cursor = cnn.cursor()
try:
sql_query = 'select name,age from stu ;'
cursor.execute(sql_query)
for name, age in cursor:
print (name, age)
except mysql.connector.Error as e:
print('query error!{}'.format(e))
finally:
cursor.close()
cnn.close()
操作结果
(u'xiaoming', 10)
(u'rose', 18)
(u'jack', 19)
(u'fang', 20)
(u'Liang', 40)
(u'Age', None)
更加规范的操作，代码如下
def select2(sql_cmd, param):
"""
:param sql_cmd sql 命令
:param param 参数
"""
try:
conn = mysql.connector.connect(**config)
except mysql.connector.Error as e:
print('connect fails!{}'.format(e))
cursor = conn.cursor()
try:
cursor.execute(sql_cmd, param)
except mysql.connector.Error as e:
print('connect fails!{}'.format(e))
finally:
cursor.close()
conn.close()
if __name__ == '__main__':
sql_cmd = "insert into stu (name, age, sex) value (%s, %s, %s)"
param = ('yangguo', 28, 'male')
select2(sql_cmd=sql_cmd, param=param) # 将命令和参数分隔开，操作起来更加安全
