In this video of our PostgreSQL Full Playlist (#41), we take a deep dive into the VALUES clause—a powerful feature that lets you define temporary constant row sets without creating a real table.

We cover a variety of real-world scenarios, including:

• Basic usage of the VALUES clause

• Assigning column aliases

• Using VALUES in INSERT statements (single and multiple rows)

• Joining VALUES with real tables in the FROM clause

• Performing bulk updates using VALUES and UPDATE together

• Working with type casting, such as filtering IP addresses

• Sorting and slicing result sets using ORDER BY, LIMIT, and OFFSET

Each example is practical, beginner-friendly, and designed to help you build solid SQL skills in PostgreSQL. Whether you're prepping for an interview or strengthening your database knowledge, this tutorial has something for everyone.
