Day 13 – UPDATE in SQL with WHERE Clause 🔁 | Modify Data in PostgreSQL Like a Pro!

Welcome to Day 13 of my 30-Day Data Analyst Challenge 🚀
Today I learned one of the most used SQL operations: the UPDATE statement with the WHERE clause in PostgreSQL!

Here’s what I covered:
🛠️ How to safely update table data
🔍 Importance of using WHERE to avoid updating everything
⚠️ What happens when you forget the WHERE clause 😨
🔥 Real-life examples to make it stick

This command may look simple, but it’s powerful — and potentially dangerous if not used correctly. Now I feel one step closer to becoming job-ready in SQL!
