Rough day? I saw you struggling with that SQL query.
It was a nightmare. I know the logic is right but the JOINs keep duplicating rows. I
felt so dumb.
Duplication usually means a one-to-many relationship you missed. That's a classic
"gotcha," not a stupidity problem. Want me to draft a post about "Mastering the JOIN"?

SQL JOINs: Why 1+1 Sometimes Equals 4 (And How to Fix It)
Created just now
today I spent 2 hours staring at a dataset that doubled in size every time I ran a
query. I thought I was bad at math. Turns out, I was just bad at JOINs.
I learned the hard way: if you JOIN a table with duplicates, you don't just "add"
data—you multiply it. This is why understanding your primary keys matters more than
writing complex logic.
Data isn't just numbers; it's relationships. And today, I finally understood this one.
