SQL (pronounced either s-q-l or sequel) is a programming language often used by professionals who work with large amounts of data. SQL helps these data professionals communicate with relational database systems to clean, sort, extract, and process the data. SQL remains highly relevant to the IT world—SQL was the most-requested skill among tech employers, according to February 2020 data from Burning Glass Technologies [1].

There are several certifications that show your competency in SQL, most of which are vendor or platform specific. Knowing what database technology your field of interest will require you to work with can help you decide which certification to get, if any.

Are SQL certifications worth it?

A certification isn’t required for many jobs that ask for knowledge of SQL, and employers can often prioritize experience over certifications. But some hiring managers may look for applicants who have related certifications. SQL or database certification requirements may be more common for positions that entail lots of time spent with technology from particular vendors or platforms. For example, if a job requires experience in Microsoft platforms, employers may request that applicants have a Microsoft SQL Server certification.

A data-related certification may position you to compete in what is projected to be a heavily in-demand industry. The field of data science is expected to be one of the fastest growing in coming years. The US Bureau of Labor Statistics listed data scientists and other mathematical science professions among the twenty occupations projected to increase the most over 2019 to 2029, at a rate of 31 percent [2]. 

SQL-related certifications can prepare you for roles like database administrator, database engineer, SQL developer, and data analyst.
