My first database query 6 months ago vs. now is wild

Back in March I was trying to figure out how to pull a list of users from a sample database and I spent 3 hours just staring at a blank SQL editor. My query was like SELECT * FROM users and that was it. I had no clue what a JOIN was or why you'd need WHERE clauses. Then last week I rebuilt our team's whole reporting dashboard at the coffee shop in about 40 minutes. I wrote a query that joined 4 tables, filtered by date ranges, and even grouped results by city. What changed? I finally sat down and did that free Codecademy SQL course over a weekend. It clicked when I realized tables are just spreadsheets with relationships. Now I laugh at past me who thought SELECT * was the peak of skill. Has anyone else had that moment where you look back at old code and cringe at how basic it was?

Started rewriting a query from last year and found I'd written SELECT FROM orders WHERE 1=1 for no reason. My past self was out here writing conditions that literally did nothing, just desperately hoping something would work. Then I figured out joins by picturing two spreadsheets sitting next to each other and matching rows like a puzzle, which made way more sense than any tutorial. Now I get real sad when I see a junior dev doing the SELECT thing because I was that person 6 months ago, staring at an empty editor like it was written in ancient Greek.

Totally had that moment. I used to think SQL was just memorizing weird commands, not actually understanding how data connects. Then I spent a Sunday morning messing with a simple join and suddenly it all clicked - now I can't believe I ever thought SELECT was enough.

My whole mindset on backend logic flipped after I spent three hours on a single LEFT JOIN that finally made me see how tables actually talk to each other. I used to think SQL was just about typing the right keywords until I realized it's way more about visualizing the relationships between your data. Now I catch myself rewatching old YouTube tutorials and thinking "how did I not see that before?
