安装pymysql
pip install PyMySQL
连接mysql
创建数据库
CREATETABLE `users` ( `id` int(11) NOT NULL AUTO_INCREMENT, `email`varchar(255) COLLATE utf8_bin NOT NULL, `password` varchar(255) COLLATEutf8_bin NOT NULL, PRIMARY KEY (`id`)) ENGINE=InnoDB DEFAULTCHARSET=utf8 COLLATE=utf8_binAUTO_INCREMENT=1 ;
建立连接
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, ('[email protected]', '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, ('[email protected]',))
result = cursor.fetchone()
print(result)
finally:
connection.close()
输出结果：
{'password': 'very-secret', 'id': 1}
