Fun Facts about Advanced SQL 🗄️✨
After diving into Advanced SQL, I found some cool facts worth sharing:
🔹 Fun Facts:
1. Window Functions are like magic — they let you calculate running totals, ranks, and moving averages without subqueries!
2. CTEs (Common Table Expressions) improve readability, but they also make debugging complex queries so much easier.
3. SQL’s CASE statements let you add “if-else” logic inside queries — turning SQL into a mini programming language.
4. You can combine multiple window functions in the same query for powerful analytics (ranking + lag/lead + moving averages together).
5. Despite being 50+ years old, SQL evolves — modern databases (like Snowflake, BigQuery, PostgreSQL) keep adding new advanced functions.
⚡ Fun Fact of the Day: The first version of SQL was called SEQUEL (Structured English Query Language) — later shortened to SQL.
