This package contains a pretty rough hack of the pure-Python MySQL client library. The goal of uPyMySQL is to be a drop-in replacement for MySQLdb and work on uPython.

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. Ditto for uPyMySQL

• uPython
• MySQL Server -- one of the following:
  • MySQL >= 4.1 (tested with only 5.5~)
  • MariaDB >= 5.1

Clone from Git and copy the upymysql folder onto your microcontroller Most likely directly copying onto your microcontroller will fail. You will likely need to re-compile micropython including upymysql into the firmware

You're pretty much looking at it

No Guarantees that these work yet:

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 upymysql import upymysql.cursors # Connect to the database connection = upymysql.connect(host='localhost', user='user', password='passwd', db='db', charset='utf8mb4', cursorclass=upymysql.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}
