Getting proficiency in PL/SQL is not a big deal, as its just a procedural extension to SQL. To better understand PL/SQL, you need to know SQL first. And since it being a 3rd generation programming language, it also doesn’t require maths to become proficient in it.
If you are interested in learning PL/SQL, start off by joining an SQL course from Intellipaat as it offers you the option to choose from online instructor-based video modules or self-paced ones with guided projects and exercises to help you gain the required practical exposure.
