Data Types In PostgreSQL: Boolean Data Types || PostgreSQL Full Playlist...

Welcome to Video #46 in our PostgreSQL Full Playlist! 🎥

In this video, we dive deep into one of the most essential data types in PostgreSQL — the Boolean Data Type. Learn how PostgreSQL handles binary logic with TRUE, FALSE, and NULL (unknown) values. We’ll walk through how to declare Boolean fields, accepted input formats (like yes, 1, off, etc.), and demonstrate real-world use cases like tracking product availability, student enrollment, and user activity statuses.

You'll also learn:

• The internal storage and behavior of booleans in PostgreSQL.

• SQL-standard vs. alternate representations ('1', 'no', 'yes', etc.).

• How NULL behaves differently and when to cast it explicitly.

• Writing smart queries using WHERE clauses for TRUE, FALSE, and NULL values.

Whether you're preparing for interviews, building applications, or just exploring PostgreSQL, this video will give you the practical knowledge you need.
