python 3.5.2安装mysql驱动报错
python 3.5.2安装mysql驱动时出现如下异常:
[root@localhost www]# pip install mysql-connector-python
Collecting mysql-connector-python
Could not find a version that satisfies the requirement mysql-connector-python (from versions: )
No matching distribution found for mysql-connector-python
这是由于官方驱动暂时只支持到python3.4所致。改用pymysql
安装pymysql
pip install PyMySQL
使用例子:
建表语句
CREATE TABLE `users` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`email` varchar(255) COLLATE utf8_bin NOT NULL,
`password` varchar(255) COLLATE utf8_bin NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin
AUTO_INCREMENT=1 ;
import pymysql.cursors
# Connect to the database
connection = pymysql.connect(host='localhost',
user='user',
password='passwd',
db='db',
charset='utf8mb4',
cursorclass=pymysql.cursors.DictCursor)
try:
with connection.cursor() as cursor:
# Create a new record
sql = "INSERT INTO `users` (`email`, `password`) VALUES (%s, %s)"
cursor.execute(sql, ('webmaster@python.org', 'very-secret'))
# connection is not autocommit by default. So you must commit to save
# your changes.
connection.commit()
with connection.cursor() as cursor:
# Read a single record
sql = "SELECT `id`, `password` FROM `users` WHERE `email`=%s"
cursor.execute(sql, ('webmaster@python.org',))
result = cursor.fetchone()
print(result)
finally:
connection.close()
