But let's get back to the topic of this article. SQL certification is like a mini diploma that tells an employer that you have a strong command of SQL and can work with databases. Often, employers value having such a document that proves your skills, so let's take a look at several SQL certifications that well-known and major global IT companies can provide you with.
