Description
🧠 LIMIT ALL in PostgreSQL — What It Actually Does & When to Use It!

Have you ever seen LIMIT ALL in a PostgreSQL query and wondered what it's doing? In this quick yet powerful tutorial, we break down the exact meaning, behavior, and purpose of LIMIT ALL, and how it compares to simply omitting the LIMIT clause altogether.

🎓 What You’ll Learn:

🔍 What LIMIT ALL actually means in SQL

🟢 How it behaves the same as no LIMIT at all

📌 When using LIMIT ALL makes sense (e.g., in dynamic query generation)

⚠️ Performance notes and when NOT to use it

✅ Real examples with an employees table for better clarity

🔄 Comparing LIMIT ALL, LIMIT NULL, and no LIMIT

While LIMIT ALL might seem unnecessary, it's useful in scenarios involving parameterized queries or dynamically generated SQL where a consistent query structure is expected.

💡 Whether you're writing reusable query templates or just aiming to clean up your PostgreSQL skills, this video will demystify LIMIT ALL and make your queries cleaner and more predictable.
