• How do i practice SQL to be real world ready?

  There was a comment here about using Leetcode, Hackerrank, SQL fiddle, etc to keep learning SQL. However, if you're aim is to go into data analytics you need to go beyond learning syntax and understand edge cases and business context. You should grind on some data analytics/data science focused platforms like stratascratch and interviewquery. They have hundreds of questions with many free ones for your to practice.
