  5 Surprising SQL Secrets That Change How You See Databases Introduction: The Hidden Language of Data Every time you stream a movie, book a flight, or 'like' a photo, you're sending a message to a hidden world—a world run by databases. These vast, invisible systems don't speak English or Spanish; they communicate using a universal language called Structured Query Language, or SQL. At first glance, SQL seems simple—a straightforward way to ask for information. But beneath its surface lies a set of powerful, and sometimes counter-intuitive, rules and capabilities that are not immediately obvious. This post will reveal five of the most surprising and impactful concepts from the world of SQL that will change how you see this hidden language of data. 1. It’s a “What, Not How” Language Unlike most programming languages where you must provide a detailed, step-by-step recipe for the computer to follow (a procedural approach), SQL is different. It's a non-procedural, or dec...
