Description
In this PostgreSQL tutorial, we explore a simple yet powerful SQL trick: sorting query results using column positions, such as ORDER BY 1, ORDER BY 2, and so on.

This syntax allows you to sort results by referring to the position of a column in the SELECT list—not its actual name. It’s especially handy in scenarios like:

Using GROUP BY with aggregate functions

Sorting when using expressions or functions

Making your queries more concise

You’ll learn:

How ORDER BY 1, ORDER BY 2 work

When and why to use positional sorting

Practical examples using a GROUP BY and aggregate query

Caveats: readability concerns and overuse in complex queries

📌 Example:

SELECT department, COUNT(*) FROM employees GROUP BY department ORDER BY 2 DESC;

This sorts the output by the second column (COUNT(*)) in descending order.

💡 This is a neat tool for developers who want cleaner, shorter SQL—but it’s also important to know when not to use it.
