🚀 Day 22 of my #30DaysSQLChallenge Today, I focused on Joins and Views in SQL. While joins are powerful for combining data across multiple tables, I found views especially interesting: 🔹 A view is like a virtual table that stores a query for easy reuse.

🚀 Day 17 of my #30DaysSQLChallenge 🚀 Today’s focus: Common Table Expressions (CTEs) A CTE is a temporary named result set that exists only within the query that follows it. Working with CTEs today helped me break complex queries into smaller steps instead

Today’s focus: applying subqueries with ANY and ALL — for example, finding employees with more vacation hours than employees in a specific department. Halfway there, and the motivation is only growing. 🚀 Let’s go for the next 15 days! #30DaysSQLChallenge #SQL #LearningInPubli


Day 2 of my #30DaysSQLChallenge I started today’s challenge by trying to fix the error I ran into yesterday using Python, but I ended up making things worse. 😅 I couldn’t do much querying because I had to go for my monthly biometric clearance, which was really exhausting.

I started my SQL journey today by downloading the Spotify dataset from Kaggle. My plan was to start simple with the SELECT statement, but things didn’t go as planned 😭. I ran into several errors while trying to import the CSV file into MySQL Workbench.
