SQL is a language which is used mostly by everyone in IT industry be it Developer, Tester, Data Engineer, DevOps, Machine Learning Engineer, Change Management, Project Manager etc. Few people use it very frequently however, there are many who use it once in a while and I know it’s difficult to remember all the syntax. So, it’s always good to have a brush up whenever needed like before going for an interview.
