So, you’ve decided that you want to become a data analyst or data scientist. Your next question might be: what skills do I need to get hired? Forget machine learning, Microsoft Excel, and R — at least for the time being. The easiest and most valuable skill that you can learn right now is Structured Query Language, better known as SQL (pronounced as “sequel.”)

Invented by IBM researchers in the 1970s, SQL is the standard language for Relational Database Management Systems (RDBMS), which is where most companies store their data.

With SQL, you can compile and manage data in large volumes (we’re talking billions of cells of data), which means that the days when your Excel would crash because you had a ton of rows in a spreadsheet are long over.

Not convinced yet? SQL is the most commonly used language in the data science industry. SQL is also one of the most in-demand tech skills at the moment and is a basic requirement for most data science jobs. According to Data Quest, SQL appears in the majority of ads for data analysts, three times more often than Python or R. It’s no surprise, then, that an average data scientist with SQL skills makes almost $90,000 a year.

If it’s so in demand, learning SQL must be incredibly difficult and time-consuming, right? Wrong! With the right course to guide you, learning SQL couldn’t be simpler. Below we have rounded up seven of the best SQL courses out there.

These are our picks for the best SQL course.

Best SQL Courses

Best Overall: Learn SQL Nanodegree (Udacity)


  • Gain a deep understanding of the SQL syntax
  • No prerequisite knowledge needed
  • Real-world student projects that you can add to your portfolio
  • Subscription includes career support services


  • Not a crash course – requires considerable time commitment

Go from "zero to hero" in this content-packed SQL course that's designed to teach you by doing rather than by listening.

We ranked Udacity’s “Learn SQL Nanodegree” as the top-rated online SQL course for many reasons. For one, as with all Nanodegrees offered by Udacity, the price includes 1-on-1 mentorship, career services, and multiple student projects. Thus, it’s effective for people hoping to redirect their careers towards database management and data analytics using SQL.

But, even more than these features, we liked the syllabus for its conciseness. The lessons in this program don’t waste any time giving broad, boring statements such as “big data is the future,” and instead the syllabus jumps right into the action: using SQL commands to accomplish real-world tasks such as joining tables, aggregating data, and cleaning up datasets.

The content of this course is excellent for people new to SQL, and the program does not require any prerequisite programming knowledge.

Here’s what you can expect to achieve by the end of the 2-month curriculum:

  • Learn all the core SQL commands, functions, and data cleaning methodologies
  • Understand SQL concepts like JOINs, aggregates, and creating temporary variables to give more meaning to the problem you are solving.
  • Gain deep knowledge of the SQL syntax and popular APIs for data analysis.
  • Learn how to design, build, optimize and debug both relational and non-relational databases.
  • Determine, create, and execute SQL and NoSQL queries that manipulate and dissect large-scale datasets.

If you’re looking for an SQL class that’ll take you from “zero to hero,” this is what you’re looking for. Udacity’s “Learn SQL Nanodegree” is the best of its kind and easily deserves the title of the absolute best online SQL class.

Gain the skills needed to query big data sets from modern distributed SQL databases with this three-course SQL Specialization designed by the data company Cloudera.

Created by the software company Cloudera in partnership with Coursera, the “Modern Big Data Analysis with SQL Specialization” is a three-course program that promises to teach you everything you need to know to work with data using SQL. While this Specialization shows you how to use relational database management systems (RDBMS), such as MySQL, its main focus is on distributed query engines, like Hive and Impala.

The curriculum consists of SQL tutorials in the form of video lessons as well as readings and discussion prompts. At the end of each week, your knowledge is tested via an auto-graded quiz. Each course also includes a practical, peer-graded assignment. For example, at the end of the second course, students have to query and analyze flight data to help a company make a better business decision.

There’s no capstone project at the end of the program. Instead, you complete all three peer-graded assignments to earn course certification.

No prior experience is required to enroll in this SQL training program, which makes it suitable for total beginners. Students can expect to finish this Specialization in about four months, provided that they dedicate about three hours a week to it. Not sure if this Specialization is for you? You can audit course content for free (but you won’t get a certificate unless you enroll in the program).

Crafted by Coursera and taught by Cloudera’s own instructors, the Modern Big Data Analysis with SQL Specialization is the best course for learning SQL. As a bonus, those that get to the end of this SQL training program should be well able to pass the Cloudera Certified Associate (CCA) certification exam (should they choose to take it).

SQL & Database Design A - Z: Learn MS SQL Server + PostgreSQL (Udemy)


  • No prerequisites
  • Clear explanations
  • Frequent discounts


  • Low audio levels
  • Some courses are a bit repetitive

Learn both PostgreSQL and MS SQL Server with this comprehensive, beginner-friendly course from Udemy.

Udemy’s “SQL & Database Design A – Z: Learn MS SQL Server + PostgreSQL” is made up of 10 sections and 104 lectures, split into 12.5 hours of SQL tutorial videos and 5 articles.

The program starts by showing you how to install PostgreSQL and PgAdmin as well as MS SQL Server. Once you get to grips with the two most popular database management systems, you’re ready to learn the basics of using SQL, how to work with data, fundamentals of database theory, how to join tables in SQL, and how to create tables in SQL. The final section of the program is devoted to database design.

Because the most important concepts are explained in a clear manner, the course is easy to follow. All practical topics are repeated twice — once for MS SQL Server and once for PostgreSQL.

Since SQL is pretty easy to learn, most people can become functional with the language in just a few weeks. That being said, the exact time frame depends on how you’re learning it and the amount of time you dedicate to it each day.

It’s easy to learn the basics of SQL. That’s because, with SQL, you’re not telling the computer HOW to do a specific task. Instead, you’re telling the computer WHAT you want — and letting it figure out the rest.

There are plenty of resources for learning SQL on your own. However, if you want to save time, you’re better off investing in a high-quality SQL course that’ll teach you the basics. After that, it’s all down to practice.
