This package contains a pure-Python MySQL client library. The goal of PyMySQL is to be a drop-in replacement for MySQLdb and work on CPython, PyPy and IronPython.

Requirements

Python -- one of the following:
- CPython >= 2.6 or >= 3.3
- PyPy >= 2.3
- IronPython 2.7
MySQL Server -- one of the following:
- MySQL >= 4.1
- MariaDB >= 5.1

Installation

The last stable release is available on PyPI and can be installed with pip:

$ pip install PyMySQL

Alternatively (e.g. if pip is not available), a tarball can be downloaded from GitHub and installed with Setuptools:

$ # X.X is the desired PyMySQL version (e.g. 0.5 or 0.6).
$ curl -L https://github.com/PyMySQL/PyMySQL/tarball/pymysql-X.X | tar xz
$ cd PyMySQL*
$ python setup.py install
$ # The folder PyMySQL* can be safely removed now.

Test Suite

If you would like to run the test suite, create database for test like this:

mysql -e 'create database test_pymysql  DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;'
mysql -e 'create database test_pymysql2 DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;'

Then, copy the file .travis.databases.json to pymysql/tests/databases.json and edit the new file to match your MySQL configuration:

$ cp .travis.databases.json pymysql/tests/databases.json
$ $EDITOR pymysql/tests/databases.json

To run all the tests, execute the script runtests.py:

$ python runtests.py

A tox.ini file is also provided for conveniently running tests on multiple Python versions:

$ tox
