Collecting / Storing Tweets with Python and MySQL

A few days ago, I published Collecting / Storing Tweets with Python and MongoDB. In that post, I describe the steps needed to collect and store tweets gathered via the Twitter Streaming API.

I received a comment on that post asking how to store data into MySQL instead of MongoDB. Here’s what you’d need to do to make that change.

Collecting / Storing Tweets with Python and MySQL

In the previous post, we store the twitter data into MongoDB with one line of code:

Unlike MongoDB where we can insert the entire json object, if we want to use MySQL instead of MongoDB, we need to do some additional work with the ‘datajson’ object before storing it.

Let’s assume that we are interested in just capturing the username, date, Tweet and Tweet ID from twitter.  This is most likely the bare minimum information you’d want to capture from the API…there are many (many) more fields available but for now, we’ll go with these four.

Note: I’ll hold off on the MySQL specific changes for now and touch on them shortly.

Once you capture the tweet (line 38 in my original script) and have it stored in your datajson object, create a few variables to store the date, username, Tweet and ID.

Note in the above that we are using the parser.parse() command from the dateutil  module to parse the created_at date for storage into Mysql.

Now that we have our variables ready to go, we’ll need to store those variables into MySQL.  Before we can do that, we need to set up a MySQL connection. I use the python-mysql connector but you are free to use what you need to.  You’ll need to do a import MySQLdb  to get the connector imported into your script (and assuming you installed the connector with pip install mysql-python.

You’ll need to create a table to store this data. You can use the sql statement below to do so if you need assistance / guidance.

Now, let’s set up our MySQL connection, query and execute/commit for the script. I’ll use a function for this to be able to re-use it for each tweet captured.

That’s it.  You are now collecting tweets and storing those tweets into a MySQL database.
