Pure Python MySQL Driver
Project description
PyMySQL
This package contains a pure-Python MySQL client library, based on PEP 249.
Most public APIs are compatible with mysqlclient and MySQLdb.
NOTE: PyMySQL doesn’t support low level APIs _mysql provides like data_seek, store_result, and use_result. You should use high level APIs defined in PEP 249. But some APIs like autocommit and ping are supported because PEP 249 doesn’t cover their usecase.
Requirements
Installation
Package is uploaded on PyPI.
You can install it with pip:
$ python3 -m pip install PyMySQL
To use “sha256_password” or “caching_sha2_password” for authenticate, you need to install additional dependency:
$ python3 -m pip install PyMySQL[rsa]
To use MariaDB’s “ed25519” authentication method, you need to install additional dependency:
$ python3 -m pip install PyMySQL[ed25519]
Documentation
Documentation is available online: https://pymysql.readthedocs.io/
For support, please refer to the StackOverflow.
Example
The following examples make use of a simple table
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()This example will print:
{'password': 'very-secret', 'id': 1}Resources
