Updated: Feb 17, 2023

DuckDB is one of the simplest, fastest databases you can use - and it's completely free! The beauty of DuckDB lies in its simplicity of setup and use. Here's a quick tutorial to help you get your hands dirty with DuckDB in 5 minutes or less

Step #1: Install DuckDB


Installing DuckDB is a breeze. Open Terminal on your Mac and type this:


brew install duckdb

Step #2: Verify if the installation has been completed


All you do is type this command:


duckdb --version

The output should look something like this:


Step #3 - We're ready to go. Fire it up!


At this point, DuckDB is already installed in your machine. To begin with I would recommend that you navigate to a folder (using terminal) which contains CSV / Parquet files that you would like to analyze. Then, simply type this command in your terminal to get started:

duckdb

At this point, duckdb is already setup and working. No more installations, no more dependencies. Easy right? Now let’s get into some analysis.


Step #4 - My first SQL queries, directly on CSV files


Run your first query on the CSV file, without any pre-processing. Assume your file is called 'input.csv'

SELECT * from input.csv limit 10;

That's it - you're already up and running with DuckDB. Here are some more commands for you to work with


1. Get a list of all commands you can work with

.help 

2. Set the working directory (for example where your files maybe present) - replace WORKING_DIRECTORY with your working directory

.cd WORKING_DIRECTORY

3. Persist your database to a file, or open an older database you've already worked with (by default DuckDB loads everything in-memory) - replace FILENAME with the file name where you would like to persist your db

.open FILENAME

4. Show the list of tables in your current database

SHOW TABLES

Conclusion
