Table of Contents
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.
- Python -- one of the following:
- MySQL Server -- one of the following:
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]
Documentation is available online: https://pymysql.readthedocs.io/
For support, please refer to the StackOverflow.
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:
