Here’s a SQL challenge that shows up in real production code more often than people expect.→ youtube.com/shorts/YMZGfG9P2lM

We’re selecting all orders and optionally joining refund data, but only for refunds over $100.At a glance, the LEFT JOIN makes it feel safe. But the final result doesn’t behave the way you might assume.

Here’s a SQL puzzle that looks almost too straightforward.→ youtube.com/shorts/KW6bXeDJEUE

Many developers would expect this to return 100. It doesn’t.

What number does this query actually return, and why?
