Dear MySQL users,

MySQL Connector/Python 8.0.17 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

Please note that the X DevAPI requires at least MySQL Server …

MySQL Server has since version 5.6 supported connection attributes for the clients. This has allowed a client to provide information such as which program or connector the client is, the client version, the license, etc. The database administrator can use this information for example to verify whether all clients have been upgraded, which client is executing a particular query, and so forth.

In MySQL 8.0.16 this feature has been included for the X DevAPI in the MySQL connectors as well, including MySQL Connector/Python which I will cover in this blog. First though, let’s take a look at how the attributes are exposed in MySQL Server.

It’s been a year since MySQL 8.0 became GA and 8.0.16 has just been released. A good time to look at what happened with MySQL Connector/Python over the last few years.

pypi presence

When we created our connector we knew hat providing it via PyPI was important and we used PyPI as distribution channel. Later PEP 470 was published, which changed how packages are hosted and we introduced the C Extension, which required re-working the packaging. It took us a bit time to get all things right, but for a while we are now back on PyPI and you can get it not only from or downloads page, but also with a simple install using the pip tool:

$ pip install mysql-connector-python

In my blog yesterday, I wrote about the new reporting framework in MySQL Shell. It is part of the 8.0.16 release. I also noted that it includes the possibility to create your own custom reports and use those with the \show and \watch commands. This blog will explore how you can create a report and register it, so it automatically is available when you start MySQL Shell.

Update

This blog was updated on 30 April to include the use of the values argument for report options. This moved the validation of the optional arguments in to the reporting framework and automatically includes the list of valid options …

Python 2 reaches EOL on 2020-01-01 and one of its commonly used third-party packages is MySQL-python. If you have not yet migrated away from both of these, since MySQL-python does not support Python 3, then you may have come across some issues if you are using more recent versions of MySQL and are enforcing a secured installation. This post will look at two specific issues that you may come across (caching_sha2_password in MySQL 8.0 and TLSv1.2 with MySQL >=5.7.10 when using OpenSSL) that will prevent you from connecting to a MySQL database and buy …

I few months ago, I wrote about using the Django framework with MySQL 8. There are also other Python frameworks that are worth considering. In this blog, I will look at using SQLAlchemy with MySQL 8.

In order for you to be able to use MySQL 8 with SQLAlchemy, you need three pieces of software: MySQL Server, MySQL Connector/Python, and SQLAlchemy. I will go through the installations, then I will look at a code example.

Information

The examples in this blog uses MySQL Server 8.0.15, MySQL Connector/Python 8.0.15, and SQLAlchemy 1.2.18. It should be possible to reuse the instructions with other MySQL versions as well, except in older MySQL versions you …

The X DevAPI allows you to work with JSON documents and SQL tables at the same time. Furthermore, the CRUD style API is more intuitive than SQL statements for some programmers. Either way, the X DevAPI allows you to mix JSON documents, SQL tables, CRUD methods, and SQL statements to give you the best of all worlds. In MySQL Connector/Python, the X DevAPI is implemented in the mysqlx module.

This blog will look at how MySQL Connector/Python handles expressions, and how you in version 8.0.14 and later need to use the mysqlx.expr() method to explicitly define expressions.

MySQL Server has a feature where you can insert data into a table from a file with the data delimited by commas, tabs, or another delimiter. This is particularly useful when you need to bulk import data, for example when restoring a backup or migrating data from one system to another including from another database product than MySQL. The mysqldump backup utility is an example of a program that supports exporting the data to delimited text files.

The statement to load the data is LOAD DATA INFILE. By default the file must be server-side and MySQL …
