Can you give an example of an SQL query to retrieve data from a database?

A simple example of an SQL query to retrieve data from the users table:

SELECT id, name, email FROM users WHERE active = 1;

This query selects the id, name, and email columns from the users table where the user is active (active = 1).

In Node.js, to execute such a query, you can use packages like mysql2 or pg for PostgreSQL.
