The 6 Best SQL Certifications in 2023

Written By Ryan Loftus | December 21, 2022

Are you thinking about earning an SQL certification to improve your career prospects? If so, you’re not alone. SQL (Structured Query Language) has become one of the most popular and in-demand programming languages in the world.

An SQL certification can be a great way to develop your database skills and advance your career. But there are many different SQL certificates that you can earn, and it can be overwhelming to try to figure out which one is the best right for you. In this blog post, we’ll take a look at some of the top SQL certificates that you can earn.

The Importance of SQL Certifications

SQL (structured query language) is the industry-standard language for working with relational databases. Used for creating, defining, and maintaining databases, SQL is a vital skill for data scientists and software engineers.

Now is a great time to further your SQL skills with a certification. In 2022, SQL was the third most in-demand language and grew faster than the average for all languages.

Earning an SQL certification has a number of career benefits, including:

  • Expanding your knowledge base
  • Improving your potential earning power
  • Earning a digital badge you can add to LinkedIn
  • Validating your skills to appeal to potential employers
  • Learning to perform complex, hands-on database activities
  • Gaining exposure to the tasks you’ll use on the job

There are many different SQL certificates that you can earn, and the best one for you will depend on your specific goals and interests. Whichever certification you choose, it can be a valuable addition to your resume and can help you to advance your career.

The right certification will also depend on the technologies you intend to work with. For example, a developer who primarily works with Oracle databases should consider Oracle’s certification program.

In general, there are two types of SQL certifications: 

  • Courses by education providers that teach foundational skills
  • Vendor-specific certifications that teach advanced skills for a particular technology

So, is pursuing an SQL certification worthwhile? 

Any certification will require a time investment, and some have an upfront cost. Whether an SQL certification is worth this investment will depend on the individual and the specific certification. With so many opportunities for professionals who know SQL, improving your database skills will always go a long way in building a successful career and increasing your earning potential. But the value of having a credential to use during your job search will depend on your career goals. 

Top SQL Certifications

While selecting a certification, pay careful attention to whether the program is active. Large technology companies often withdraw or retire their certifications programs, and may or not replace them with a new certification. Any list of SQL certifications runs the risk of sharing a link to a withdrawn course. You should also keep in mind that some certifications expire. If maintaining an SQL certification is important for your career, you may need to redo the program every few years.
