Using Connector/J with Python
+1 Vote Up -0Vote Down

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 …

The performance of MySQL Connector/Python with C Extension
+0 Vote Up -0Vote Down

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.

+0 Vote Up -0Vote Down

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 […]

New! MySQL Connector/Arduino release-1.0.4 GA and Documentation
Employee +1 Vote Up -0Vote Down

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.

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 …

MySQL Connectors, a Real Plus for Developers
Employee_Team +2 Vote Up -0Vote Down

MySQL Connectors provide connectivity to the MySQL server for client programs. APIs provide low-level access to the MySQL protocol and MySQL resources. Both Connectors and the APIs enable you to connect and execute MySQL statements from another language or environment. Oracle provides a number of these, enabling developers to build database applications in the language of their choice. Among those developed by Oracle are drivers for JDBC and ODBC. Any system that works with JDBC or ODBC can use MySQL. And you can find many more, including drivers for PHP, Perl, Python, Ruby, Tcl and even …

I've completed a new release of the Connector/Arduino. The new version supports a few refinements and a new feature.

  • New! disconnect() method - enables disconnect from server. Note: you must call mysql_connect() to reconnect.
  • Better error handling for dropped packets. No more random reboots when bad packet appears.
  • Library can recover from short-term loss of connectivity. Along with bad packets is a check to make sure what is received is valid making the connector ignore garbage packets associated with a dropped connection.
  • Detection of Out of Memory condition. Should there not be …

MySQL Connector/Arduino
+0 Vote Up -0Vote Down

Chuck Bell, one of my former colleague from MySQL AB, has created a connector for Arduino to MySQL. So this allows Arduino code to be a direct client of a MySQL or MariaDB server, with Ethernet and WiFi shields supported.

With Arduino boards being used more and more, this can come in really handy – not only for retrieving (for instance) centralised configuration data, but also for logging. Useful stuff. Thanks Chuck!
