Description
Want to make your SQL queries easier to read and write? Table and column aliases in PostgreSQL help you simplify complex queries by giving temporary, meaningful names to tables and columns. Whether you're working with long table names, complex joins, or subqueries, aliasing makes your SQL more readable and efficient.

What You’ll Learn in This Tutorial:
✔️ What table and column aliases are and how they work in PostgreSQL
✔️ The AS keyword and its role in aliasing (and when it’s optional)
✔️ How to use aliases in JOIN queries for better readability
✔️ Using aliases to simplify subqueries and derived tables
✔️ Best practices for writing clear and efficient SQL queries

Table and column aliases are essential for clean SQL code, especially when working with large databases and multi-table joins. We’ll go through real-world PostgreSQL examples to demonstrate how aliasing improves query clarity and maintainability.

By the end of this tutorial, you'll be able to write professional, optimized, and structured PostgreSQL queries using aliases like a pro!
