MySQL Connector/NET 7.0.7 m6 development has been released

MySQL Connector/Net 7.0.7 is the fourth development release that expands cross-platform support to Linux and OS X when using Microsoft’s .NET Core framework. Now,
.NET developers can use the X DevAPI with .NET Core and Entity Framework Core
(EF Core) 1.0 to create server applications that run on Windows, Linux and OS X.
We are very excited about this change and really look forward to your feedback on it!

MySQL Connector/Net 7.0.7 is also the sixth development release of MySQL Connector/Net to add support for the new X DevAPI. The X DevAPI enables
application developers to write code that combines the strengths of the
relational and document models using a modern, NoSQL-like syntax that
does not assume previous experience writing traditional SQL.

To learn more about how to write applications using the X DevAPI, see

New Release! MySQL Connector/Arduino 1.1

The newest release of the MySQL Connector/Arduino library release-1.1 alpha is available for download. This new version represents a major step forward for the library in ease of use. Here are just a few of the important changes in this release.

  • Added to Library Manager : yes, you can download and install the library from the Arduino IDE now. Just open the Library Manager and search for "MySQL".
  • More Example Sketches : there are many more example sketches of how to use the new library from basic connections to complex queries and more! 
  • Redesigned Classes : the library has been redesigned with new classes making it much easier to use a wider variety of shields and modules. Now, you pass in the Client class for your shield and so long as it adheres to the Ethernet.Client primitive, you can use any library to initiate …

Using Connector/J with Python

With Python you would normally use MySQL Connector/Python or the older MySQLdb to connect from Python to MySQL, but there are more options.

There are also multiple Python implementations: CPython (the main implementation), PyPy, Jython and IronPython. PyPy tries to be faster than CPython by using a Just-in-Time compiler. Jython runs on the JVM and IronPython runs on the .NET CLR.

Connector/Python by default (Without the C Extension) is a pure Python implementation and can work with most if not all implementations. And for MySQLdb there is a drop-in replacement called PyMySQL, which is a pure python implementation.

So there are many options …

The performance of MySQL Connector/Python with C Extension

The source of this post is in this gist on nbviewer.

After reading about the difference between MySQL Connector/Python and MySQLdb on this blog post I wondered how the C Extension option in Connector/Python would perform.

If you want to run the code yourself you'll need: Jupyter/IPython, Python 3, Requests, MySQLdb, Connector/Python, Matplotlib, Pandas and MySQL.

In [1]:

%matplotlib notebook

In [2]:

import random
import gzip
import time

import pandas as pd
import matplotlib.pyplot as plt
import requests
import mysql.connector
import MySQLdb
for imp in [mysql.connector, MySQLdb]:

MariaDB Connector/J failover support – case Amazon Aurora

MariaDB Connector/J has evolved a lot during the year. In this post I will talk about the failover capabilities in the connector and give some guidance on how to use them in some certain cases. One other important new feature that I’ll cover in a later article is the fact that MariaDB Connector/J can do […]

The post MariaDB Connector/J failover support – case Amazon Aurora appeared first on MariaDB.org.

New! MySQL Connector/Arduino release-1.0.4 GA and Documentation

After several iterations and a long period of community evaluation, I am happy to report I've released the newest, stable release of the MySQL Connector/Arduino. This library is designed to allow you to connect your Arduino via an Ethernet or WiFi shield to a MySQL database server running on your network (or the Internet!).

New Documentation!Best of all, I've written a reference manual that includes examples of how to use the connector in a variety of ways. Included in the document are advice on how to write your sketches, troubleshooting tips, and a long FAQ compiled from the many questions from my blogs.

Changes The only code change in this release is to fix a defect when using the connector with the latest versions of MySQL.

Announcing MySQL Connector/Arduino 1.0.2 Beta

I've completed a new release of the Connector/Arduino! The new release contains some major improvements with memory handling.

  • The library has been trimmed to save memory.
    • Static strings moved to PROGMEM strings
    • Unused structures removed (e.g. ok_packet)
    • Moved two more methods to optional compilation
  • The WITH_SELECT is turned *OFF* by default. If you want to use select queries, be sure to uncomment this in the mysql.h file.
  • Added a CHANGES.txt file to track changes between releases.


Memory, What Memory?
If you have used previous versions of the connector in medium to large sketches or have long query strings or even many variables, chances are you have hit the memory limit for your wee Arduino board.

This can manifest itself in a number of ways. Most notably, the sketch may work …
