That moment of chills down your spine when you delete a few records in a huge production db and thinks "strange, this is taking longer than it should?" and suddenly realise that you forgot to include the "where"-clause in the statement...

Mistakes were made

"Sysen, do we have a current backup of that database?"
"Why?...did you mess something up again?"
🙈
After a few hooplas I tend to show all (major) querys at least one person before I run them. Too much has happened in the past 😂

Manager
Do this NOW.
Me:
This is complex, been working since 9 hour due to the other project....
Manager
But it must be done NOW, it's just deleting a few files and dirs
Me:
Ok...

Half an hour later, guess which production server has had an OS till deletion of a few files and dirs?

Remember, if your brain is completely mushy and your instinct says... Nope. This won't end well.... Better ask a coworker or just post pone it. Even if the bad manager yells at you.
