I’m a software developer, but I also run a transport and logistics business. Usually, I’m the guy preaching about backups, staging environments, and proper migrations. But today, "Monday Brain" hit me hard.
I noticed a small naming inconsistency in our transport logs. Instead of doing the same thing writing a proper migration script and testing it I thought, I can just run a quick SQL command to fix this in 5 seconds.
What’s the worst that could happen?
Well, the "worst" happened. I missed a crucial WHERE clause.
In a split second, I watched as the database executed the command across the entire table. I didn't just rename an entry; I corrupted the relationship links for three days' worth of logs.
I spent the next six hours manually reconciling paper manifests with digital fragments, sweating while my drivers were calling me asking why their schedules were blank. I tried to save 5 minutes and ended up losing an entire workday and a significant amount of hair.
TL;DR: Tried to be a 10x Developer with a 5 second database fix, forgot a WHERE clause, and nuked three days of transport logs for my business.
