Hi everyone, here's the link to the project I created for the #30DaysOfSQL challenge. I'd love your thoughts and feedback. Thank you for engaging. github.com/Elizabeth-moyi… #learnwithmoyinofcanada #30SQLchallenge #Datacommunity @cheftee_lead @Odunthedatagirl
It's day 30 of my 30 day SQL learning challenge, and it's been quite a journey. From struggling to import datasets into SQL Workbench and facing errors to mastering joins, subqueries, CTEs, and complex SQL functions that challenged my life choices.
Day 21 of my #30SQLChallenge 🚀 Today’s learning was all about Running Totals and Moving Averages in SQL. A running total is a cumulative sum that grows as new rows are added. It helps track progress over time, such as total sales up to a given date.
Day 13 of my #30SQLChallenge 🚀 Today’s focus: Subqueries in SQL A subquery is simply a query nested inside another query. They are powerful because they allow you to break complex problems into smaller, manageable steps.
