Learn SQL FAQs
Why learn SQL?
It is a necessary tool for data science. Virtually all data science work requires connection to and manipulation of databases. SQL is designed to make data management simple and efficient and is thus a necessary language for anyone looking to become a data scientist.
What is the best way to learn SQL?
The best way to learn SQL is through hands-on practice in a course that’s designed to give you real-world SQL skills.
DataCamp’s online courses take you from an SQL newbie to a master of the database query, all while learning SQL at your own pace and from anywhere in the world.
If you’re new to SQL, the best way to start learning is with DataCamp’s Introduction to SQL course. You’ll learn the basics of this programming language and become familiar with its code. You’ll also learn how to ask questions (queries) of the world’s most popular relational databases such as Microsoft’s SQL Server, MySQL, and PostgreSQL.
Once you’ve learned SQL syntax and this language’s basic query commands, you can start sifting through data and gaining insights.
If you already know some SQL basics, DataCamp’s Intermediate SQL course is the next step. Learn how to use SQL to handle complex queries and create datasets for analysis in PostgreSQL.
How long does it take to learn SQL?
2 weeks to 2 months. The basics of SQL can be learned in DataCamp's 4hr Introduction to SQL course, but gaining proficiency will take more time and practice until your "SQL Muscle Memory" kicks in.
How hard is it to learn SQL?
Not hard at all. SQL is similar to Python in that it has an English-based syntax, making for easy readability.
What should I learn after SQL?
Python and R if you haven't already. Python and R are two extremely popular languages within the data science industry. Python is easy to learn, has an English-based syntax like SQL, and is great for automation. R was designed specifically for data science and will help you analyze massive amounts of data at once - it is a great tool to have.
Where should I learn SQL?
Online at DataCamp! Datacamp has SQL courses, tutorials at all levels, projects, and a workspace to ensure your progression on your SQL journey.
When should I learn SQL?
Ideally at the same time as learning Python or R. Being able to connect to and manipulate data sets via SQL is an essential part of data science. It's not a "learn after or before Python or R" skill, as the skills are complimentary. Without understanding SQL, you won't be able to properly use Python or R. Datacamp has a free introductory SQL course followed by more advanced courses to round out your knowledge of SQL.
Is SQL a valuable skill to have?
Yes. Every organization that stores information in databases can use SQL, from hospitals and schools to businesses large and small. It is for this reason that SQL is one of the most in-demand skills that companies are looking for. Why is it so useful? You can think of SQL as a supercharged Microsoft Excel. Using SQL, you can access, query, and extract huge amounts of data from multiple databases. It also allows you to perform powerful cross-database analyses. In summary, data scientist at Airbnb Robert Cheng probably puts it best: "If I want to pick one thing for all data scientists to learn, I would say learn SQL."
Do I need to download any software to learn SQL on DataCamp?
No. You can learn SQL on DataCamp without installing any software—all the training and exercises can be completed in your browser.
