# 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/) \>= 10.3

## 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}
```
