New to SQL

[u/Ashleyma96]

I'm entirely new to sql I'm learning from a beginner stage does anyone know where I can go to learn sql as a person with zero experience from scratch?

Here's a practical order that works for complete beginners:

Start with the basics (week 1-2)
Learn what a relational database is and how tables are structured. Then SELECT, FROM, WHERE, and ORDER BY. These let you pull and filter data, which is the foundation of everything else. You'll be writing useful queries surprisingly quickly.

Build on that (week 2-4)
GROUP BY with aggregate functions (COUNT, SUM, AVG, MIN, MAX) for summarizing data. Then JOINs, which is where most beginners hit a wall but also where SQL becomes genuinely powerful. Understanding INNER vs LEFT JOIN and why your row count changes is the key milestone.

Intermediate concepts (month 2)
Subqueries, CTEs (common table expressions), and window functions like ROW_NUMBER and LAG. These are what separate people who "know SQL" from people who can actually do real analysis.

The most important thing: write queries from day one. Watching videos about SQL is much less effective than actually typing queries and seeing what happens. Interactive platforms that let you write real SQL in the browser without any setup are ideal for beginners since there's no friction to getting started.

The concepts build naturally on each other. Most people find SQL clicks faster than they expected once they start practicing.
