[](https://pymysql.readthedocs.io/) [](https://codecov.io/gh/PyMySQL/PyMySQL) # PyMySQL This package contains a pure-Python MySQL client library, based on [PEP 249](https://www.python.org/dev/peps/pep-0249/). ## Requirements - Python -- one of the following: - [CPython](https://www.python.org/) : 3.7 and newer - [PyPy](https://pypy.org/) : Latest 3.x version - MySQL Server -- one of the following: - [MySQL](https://www.mysql.com/) \>= 5.7 - [MariaDB](https://mariadb.org/) \>= 10.4 ## Installation Package is uploaded on [PyPI](https://pypi.org/project/PyMySQL). 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](https://stackoverflow.com/questions/tagged/pymysql). ## Example The following examples make use of a simple table ``` sql 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=utf8mb4 COLLATE=utf8mb4_bin AUTO_INCREMENT=1 ; ``` ``` python import pymysql.cursors # Connect to the database connection = pymysql.connect(host='localhost', user='user', password='passwd', database='db', cursorclass=pymysql.cursors.DictCursor) with connection: 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) ``` This example will print: ``` python {'password': 'very-secret', 'id': 1} ``` ## Resources - DB-API 2.0: <https://www.python.org/dev/peps/pep-0249/> - MySQL Reference Manuals: <https://dev.mysql.com/doc/> - MySQL client/server protocol: <https://dev.mysql.com/doc/internals/en/client-server-protocol.html> - "Connector" channel in MySQL Community Slack: <https://lefred.be/mysql-community-on-slack/> - PyMySQL mailing list: <https://groups.google.com/forum/#!forum/pymysql-users> ## License PyMySQL is released under the MIT License.
