How to Learn SQL

If you work or dabble in the computer world, you may have heard of SQL. SQL stands for Structured Query Language, and it serves as a standard language for accessing and working with databases.

Developed at IBM in the 1970s, many programmers continue to use SQL to this day —as well as business professionals, data scientists, marketing managers, data journalists, and anyone who works with databases in their day-to-day jobs.

In addition to answering the question, “What is SQL?,” this guide offers advice on the best way to learn SQL and recommends bootcamps for aspiring programmers.

The good news is: You don’t need to identify as a computer whiz or possess prior programming skills to learn SQL. You don’t even need to enroll in college to master this database language.

That said, although some people teach themselves, this requires intense discipline —and beyond SQL basics, it can become frustrating without guidance. Two popular options for learning SQL include online courses and coding bootcamps.

Online courses are a popular option for individuals who prefer flexible learning. They often come with low costs, and some are even free. For SQL learners who may need to fit their practice into already busy lives, online courses often allow them to work at their own pace without committing to a specific timeframe.

Still, some online courses are better than others, so make sure you read reviews from previous students so you know what to expect.

For students who are looking for a more intensive or structured option, coding bootcamps could prove a better fit. Bootcamps usually use a cohort model and allow students to practice their skills with hands-on projects. Bootcamp students often learn SQL through data science or data analytics bootcamps. These programs teach other advanced skills as well, like Python and machine learning.

Once you learn SQL, you’ll be an expert in managing and working with databases. You can leverage this expertise in many careers, such as SQL developer, database administrator, data analyst, or SQL server developer.

Other career paths that are well suited for individuals with SQL skills include big data engineers, who use databases and SQL to manage their datasets; quality assurance testers, who keep track of and find patterns in their findings through SQL; and investigative and data journalists, who use SQL to crunch numbers.

Plus, many business professionals often need to analyze large sets of data. Business analysts, product support analysts, and marketing managers often shine in their jobs when they use SQL skills.

Although positions typically do not require job candidates to possess SQL certification, an SQL credential can boost job prospects. Certification shows employers that you hold legitimate expertise in the area instead of a passing interest or a quick line on your resume. This can result in more job opportunities and even higher salaries.

You can earn certification by taking a professional exam. Oracle University offers the following credentials that you can earn through an exam:
