Getting Started with Haskell Data Analysis

SQLite3 and regular expressions

Working with regular expressions in our SQLite3 database is no different than working with a CSV file. In this section, we will demonstrate how to filter our data using regular expressions, using the timestamp data from an SQLite3 database in a similar manner to our last section. So, we're going to be loading the data from the SQLite3 database, sifting through that data using a regular expression, and analyzing the data gleaned from that regular expression. Now, the problem that we will try to solve in this section is to determine how many earthquakes happen by hour in our 7-day database. Let's go and create a new Haskell notebook; we will name this notebook RegexLearning-SQLite3. Let's first import our libraries: ...
