My personal commitment to the 21-day SQL challenge: building consistency one day at a time.

💾 21 Days IDC Challenge: SQL Mastery

"21 days to turn SQL commands into second nature."

This repository documents my journey through the 21-Day SQL Challenge (IDC = I Dig Columns!). The goal is consistent, daily practice to master foundational to intermediate SQL concepts.

---

🎯 The Core Challenge

• Duration: 21 Consecutive Days (Commit to a start date!).

🔑 Key Concepts to Master

For this challenge, I will focus on reinforcing these fundamentals:

• Tables store data in rows (records) and columns (fields).
• SELECT defines which columns to retrieve.
• FROM specifies which table to query.
• Use semicolon (;) to end SQL statements.

📜 How to Track Progress (The Rules)

1. Daily Log & Query: I will post a log of my progress and the SQL query I worked on every single day in my personal log file.
2. Location: All daily updates will be located in the /Daily-Logs folder.
3. Accountability: Missing two days in a row means restarting the challenge from Day 1!
4. Proof: Each log entry must include the day's main SQL query and a brief explanation of the result.
