“Dataquest teaches me everything I need to know without the $50,000 degree. It’s self-paced, and I love learning by doing. It took away the guesswork of trying to learn by myself.”


Isaac Pato

Data Science / Quality Engineer

“For me, Dataquest was great because it was all hands-on projects — there weren’t any videos, so I could just read through and go at my own pace. I felt that starting from the beginning was great. I had a programming background, but the beginning courses provided a great review. Dataquest was key to getting my first job.”

FAQs about SQL

How to I teach myself SQL?

If you use Dataquest, teaching yourself how to learn SQL is very simple. There are 3 simple steps:

  • Step 1: Select your learning path. Explore the different data roles, and determine which one is right for you. Pick a path, and complete your first course for free.

  • Step 3: Showcase your skills. Use the projects you’ll build on Dataquest to impress recruiters and grow your career.

Can I learn SQL 3 months?

Absolutely! If you want to learn SQL on its own, it usually takes 2 to 3 weeks to get the hang of it. However, SQL is usually paired with other languages. For example, in data science, students will also usually learn Python or R.

Is it hard to learn SQL?

Learning SQL can be hard if you don’t have the right support or learning resources. To make it easy, there are three things that you must have:

  1. A platform that guides you on what to learn and when
  2. Fun SQL projects that keep you highly motivated and help you apply what you learn using real code
  3. A vibrant community to help you when you get stuck

Thankfully, Dataquest has all of these things!

Is SQL enough to get a job?

This depends on the role you’re pursuing. For example, knowing only SQL may be enough for a job as a database administrator. However, if you want to become a data scientist or data analyst, then you’ll also need to learn another programming language like Python or R.

What’s the easiest way to learn SQL?

While we may be a bit biased, we think the easiest and best way to learn SQL is with Dataquest. Our SQL courses are built by experts, designed for beginners, and made with employers’ hiring conditions in mind.

Plus, unlike SQL bootcamps or certification programs, our subscription is very affordable.
