Fetching rows as dictionaries with MySQL Connector/Python (revised)
Employee +4 Vote Up -0Vote Down

It is possible with MySQL Connector/Python to define your own cursor classes. A very good use case is to return rows as dictionary instead of tuples. This post shows how to do this using MySQL Connector/Python v1.0 and is an update for an older blog entry.

In the example below we are subclassing the MySQLCursor class to create a new class called MySQLCursorDict. We change the _row_to_python() method to return a dictionary instead of a tuple. The keys of the …

Naming a Python package for distribution?
Employee +0 Vote Up -0Vote Down

I’m currently figuring out how to name the MySQL Connector/Python distributions so it works well with PyPi. Source archives would be named like mysql-connector-python-X.Y.Z.tar.gz.

The ‘name’ metadata would be ‘MySQL Connector Python’, thus without any underscores or dashes. This works OK, but if people have objections, please leave a comment.

Invalid dates returning None, or raise error using Connector/Python?
Employee +0 Vote Up -0Vote Down

In this blog we discuss invalid dates in MySQL, how to retrieve them using Connector/Python and we raise the question: Should Connector/Python raise an error or just keep returning None on invalid dates?

If you run MySQL without proper SQL Modes, you will be able to update and
read invalid dates such as ’2012-06-00′. If you’ve payed attention the past decade, you’ll know that you can prevent this configuring your MySQL server setting SQL Mode …

Automatic reconnect in MySQL Connector/Python?
Employee +0 Vote Up -0Vote Down

There have been some request to have some reconnect possibilities in Connector/Python. I’m wondering now whether there should be some automatic reconnect on certain errors within the database driver.

My personal feeling is to have no automatic reconnect within Connector/Python and the programmer has to come up with retrying transactions herself.

For example:

        cnx.disconnect() # For testing..
        tries = 2
        while tries > 0:
                tries -= 1
                try:
                        cursor.execute("INSERT INTO t1 (c1) VALUES ('ham')") …
