Dear MySQL users,

MySQL Connector/Python 8.0.14 is the latest GA release version of the
MySQL Connector Python 8.0 series. 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
http://dev.mysql.com/doc/x-devapi-userguide/en/. For more information
about how the X DevAPI is implemented in MySQL Connector/Python, and its
usage, see http://dev.mysql.com/doc/dev/connector-python.

Please note that the X DevAPI requires at least MySQL Server version 8.0
or higher with the X Plugin …

Maybe the biggest new feature in MySQL 8 is the new transaction data dictionary that improves the consistency of schema objects among other things. To further protect the data in the data dictionary, the data dictionary tables are hidden and their content only exposed through the Information Schema. (One exception is when you use the debug binary, then it is possible to get direct access to the data dictionary tables. This is not recommended at all on production systems!)

A side effect of the data dictionary tables being hidden is that those that have had a habit of manipulating the tables directly in MySQL 5.7 and earlier (I will not recommend doing that) will no longer be able to do so. Examples of manipulating the tables include …

If you have an application that need to use multiple connections to the MySQL database for short periods of times, it can be a good to use a connection pool to avoid creating a new connection and going through the whole authentication process every time a connection is needed. For the Python Database API (PEP249), MySQL Connector/Python has had support for connection pools for a long time. With the release of MySQL 8.0.13, the new X DevAPI also has support for connection pools.

This blog will first cover the background of the X DevAPI connection pool feature in MySQL Connector/Python. Then …

MySQL Shell makes it easy to develop tools you can use for example to generate reports. In a previous blog, I showed how to use external modules in MySQL Shell. In this blog, I will take it one step further and use the curses Python module to create auto-refreshing reports. The first example will be kept very simple to show the idea, then a more realistic example will be shown where the top N files sorted by I/O will be returned.

Note

Out of the box, this does not work on Windows as Python does not ship with the curses library.

Basic Example

As a basic example, consider the query SELECT NOW(). This returns …

A framework can be a great way to allow you to spend more time on the actual application or web site and less time on standard tasks. It can also greatly reduce the amount of custom code needed. Django is one of the best known web frameworks for Python, and the good news is that it works out of the box with MySQL Server 8 and MySQL Connector/Python 8. This blog will look at how to use Django with MySQL 8.

There actually is very little to get Django to work with MySQL 8. Just install it, configure Django to use MySQL Connector/Python as a backend, and that’s it. From the Django point of view, you just have to configure the database option in settings.py to use MySQL Connector/Python and your database settings, for example:

DATABASES = { …

First of all, thanks to everyone who attended my sessions at the recent Oracle OpenWorld and Code One in San Francisco. It was a great privilege to be allowed to make a number of presentations.

All of the workbooks and scripts from the hands-on labs (HOL) and the slides from the talks have been made available at OpenWorld’s and Code One’s session catalogues. You can download the files by using the OpenWorld catalog searching for my name or the session number (see below). Click on the download icon for each of the presentations you are interested in.

Dear MySQL users,

MySQL Connector/Python 8.0.13 is the third GA release version of the
MySQL Connector Python 8.0 series. This series adds support for Python
3.7. 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

The MySQL Document Store became general available (GA) with MySQL 8. One of the nice features of the MySQL Document Store is the X DevAPI that allows you to query the data from a multitude of programming languages using the same API (but while retaining the conventions of the language). The programming languages with support for the X DevAPI includes JavaScript (Node.js), PHP, Java, DotNet, and C++.

I will be using MySQL Connector/Python 8.0.12 for the example in this blog. The example is executed on Microsoft Windows with Python 3.6 installed, but it has also been tested on Oracle Linux 7 with Python 2.7. I do assume that MySQL Connector/Python has been installed. If that is not the case, you can read how to do it in the …

One of the nice things about MySQL Connector/Python is that it is available in a pure Python implementation. This makes it very portable. Today I have been exploring the possibility to take advantage of that to make MySQL Connector/Python available on my iPad.

There are few Python interpreters available for iPad. The one I will be discussing today is Pythonista 3 which has support for both Python 2.7 and 3.6. One of the things that caught my interest is that it comes with libraries to work with iOS such as accessing the contact and photos as well as UI tools. …
