6 Best Free Online Courses to Jumpstart Your Learning of SQL
 
By Sourabh Bajaj
We scoured the internet for the best free courses for anyone looking to learn SQL, a language that helps anyone – Product Managers, Data Scientists, Marketers, Sales people, Finance teams – work with data. We’re excited to share the top 6 resources we found.
 
 
SQL (Structured Query Language) is a language used for database management: it allows you to retrieve and manipulate data stored in databases. If you have ever needed to ask someone to pull data so you could answer a business question, you would benefit from being able to use SQL to access the data yourself. Put simply, SQL allows you to unlock the power of data for yourself, your team, and your business. 
SQL has been around since the 1970s, and despite considerable evolution in programming languages since then, SQL remains a tried and true language used for data manipulation. Most database systems, like MySQL, PostgreSQL, Oracle, and Microsoft SQL Server interact with SQL. While many programming languages have come and gone since the 1970s, SQL has maintained its popularity in the Relationship Database Management System (RDMS) realm. In fact, it has advanced considerably, and seems likely to maintain its foothold as a go-to language for data manipulation.
 
 
In the information age, being able to access, manipulate, and get value from data is an incredibly powerful skill. The amount of data online is proliferating rapidly, and SQL allows you to make sense of this information. Being able to draw valuable insights from data will make you a more valuable member of any organization.
 
 
In this economic climate, one thing is clear: learning SQL is a great skill to add to your resume and a surefire way to grow your job prospects. Whether you work in IT, Marketing, Finance, Product Management, or Data Science, learning SQL is a great investment in your career. 
 
 
 
CoRise combines industry-leading instructors, a global community of classmates, and interesting applied projects to create a learning experience far better than any other we saw out there. Their course is two weeks long and takes you from a complete beginner to being able to write queries, supporting you every step of the way. We highly recommend this to anyone hoping to dive in and get a ton out of their two-week experience.
 
 
 
This course by Udemy is a great option for people who want the flexibility to learn at their own pace, by video, instead of being supported by a community of learners. In this course, you’ll learn how to query a database, create tables and databases, and ultimately be proficient with basic SQL querying.
 
 
This is a great option for anyone looking to learn how to use SQL to work with the PostgreSQL database, in particular. PostgreSQL is the most advanced database used to build back-end systems. You can learn about it via free YouTube videos linked above.
 
 
This is another great, learn-at-your-own-pace option, for people who are specifically interested in using SQL to work with the Oracle database. In this course, you will learn how to write basic SQL statements to view data, insert data, update existing data and delete data in an Oracle database.
 
 
While admittedly not the best looking option on our list, the references SQLZoo have compiled are tremendously helpful for future SQL querying. This serves as a great resource to bookmark and come back to in the future.
 
 
This self-paced and video-based course from Coursera is a great option for people interested in learning SQL, but with limited time to do so. You’ll learn the fundamentals of SQL via videos you can watch at your own pace.
