About This Class

SQL is the computer language used to access data in most databases. And, according to this blog post, "it’s been one of the greatest skills I could have ever acquired as a marketing / business guy at a startup."

This class is intended for those with absolutely no SQL experience whatsoever, but want to learn. Here are some common symptoms that can be cured by learning SQL:

  • you are always asking Engineers to get data for you
  • Excel can’t handle all of the data you’re working with
  • you’re a web designer that wants to start working with databases
  • you like to learn new things

By the end of the class you'll be able to write basic to intermediate queries, which means: 

  • You can get raw data for yourself -- quickly
  • You can perform sophisticated analysis of millions of rows of data
  • You can calculate your sales by month, you most profitable product, your most loyal customer, and so on

Here is what we will cover in the class:

  • How SQL databases are structured
  • The types of information that databases store
  • How to access rows in a database
  • How to filter a database for only those rows that meet certain criteria
  • How to join information across multiple tables in a database
  • How to perform mathematical operations that analyze and summarize data

We'll be using a sample set of e-commerce data to write the data queries that you can later apply to any set of data, once you get your hands on it!

All you need to bring is a laptop -- we'll practice SQL using a web-based database. Note: SQL is a language used in MySQL, Oracle, Postgres, etc. Each system implements SQL slightly differently, but the basic queries we'll be covering will work on any of these systems.

Very easy to understand and logically structured for someone who is not familiar with coding and syntax.
Great instructor. He explained things well and I appreciated his passion for the subject. Liked the mock web content for practicing queries. When you moved into advanced queries, the pace went a bit fast- was still learning the significance of the basic queries and how to do them right. I was truly a beginner and the speed picked up a lot in the end. Would have liked more detailed instructions on what we were to do, and specifically what our project was to be. Like that I will have access to this and can go back and practice. Found it easier to work backwards- take the answers and deconstruct them. Appreciated all of the resources made available as well. Disappointed your web program crashed, hope it is made available so I can practice.

I didn't get to spend as much time in the class as I'd liked but Dan was very thorough and I recommend this class to anyone starting out with SQL and wanting to get a basic understanding of interacting with databases.

I’m the Director of Community at FirstMark Capital. I’ve taught nearly 400 students on Skillshare and am a Master Teacher, a distinction which only a small group of teachers have. My class topics range from SQL intro classes to workshops on learning to code in 120 minutes. You can read my 100+ student endorsements here. I taught myself to code in high school, then majored in computer science (and TA'd intro to CS) in college. Then I forgot most of it. Then I started coding again and got most of it back. Also, I love to teach.
