🚀 Day 28 of my #30DaysSQLChallenge – Analytics SQL: Time Series Analysis Time series analysis isn’t just for data science tools like Python or R — you can do a lot directly in SQL! I’ve practiced different SQL techniques that help uncover trends and insights over time.

🚀 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
