Data Types in PostgreSQL: Network Address Data Types || PostgreSQL Full ...

In this video, we explore Network Address Data Types in PostgreSQL — an essential part of working with IP addresses and MAC addresses directly in the database.

You’ll learn how PostgreSQL provides specialized support for IP address types such as inet (IPv4/IPv6 hosts), cidr (network blocks), and MAC address formats like macaddr and macaddr8. These data types are far more reliable and efficient than storing IPs as plain text, allowing for input validation, indexing, subnetting operations, and more.

We also provide practical examples, including:

• Creating tables using inet, cidr, macaddr, and macaddr8

• Inserting and querying IP and MAC addresses

• Using powerful built-in functions like host(), netmask(), abbrev(), and macaddr8_set7bit()

• Understanding the difference between inet and cidr

If you're building applications involving network infrastructure, IoT devices, firewalls, or logging systems — this tutorial is a must-watch!

VALUES Lists in PostgreSQL Queries || Queries in PostgreSQL || PostgreSQ...

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.
