Description
🧪 No Columns? No Problem! Learn Static SELECT Expressions in PostgreSQL
Did you know you can write SQL queries without selecting any data from a table? In this unique PostgreSQL tutorial, we explore simple and static expressions in SELECT—perfect for testing logic, returning constants, or initializing values.

📌 This video is short, sharp, and incredibly useful, especially for debugging, learning, and experimenting with expressions like math operations, string literals, functions, and timestamps.

🎯 What You'll Learn:
✅ How to run a SELECT without referencing any table
✅ Using arithmetic operations (e.g., SELECT 2+3 AS result)
✅ Returning static strings (SELECT 'Hello' AS greeting)
✅ Calling functions like SELECT now()
✅ Real-world uses of static SELECTs (e.g., testing, templating, logic check)

💡 Great for SQL learners and pros alike, this trick shows that not every SELECT needs to come from a database table!
