Also, I'm pretty sure I've said this before, but I'll say it again:

Part of your job as a senior is to tell your juniors about your fuckups. The embarrassing cringe reckless and lazy bullshit that you did when you were new, and the various times you brought down Prod. We ALL did it sometime. And then tell them: the moment you realized you fucked up, I know, the impulse is to try and cover it up, but don't do it. Come to the seniors you trust, and they'll help you unfuck it, and fight management tooth and claw like mamma and pappa bears to defend you from any shitheads in management. Because that's what our seniors did to us.

in 1996, after midnight, dialed in to a friend's linux machine across the country to fix it for something critical the next morning:
# dpkg -l | grep ^ii >/tmp/inst.pkg
# mkdir /debs
# mv / *.deb /debs
# ls -latr
ls: error while loading shared libraries: libc.so: cannot open shared object file: No such file or directory

... oh no. (That was the night I learned that you could use echo and shell globbing as a rudimentary ls, and that you could use ld.so as a preload)

@JessTheUnstill Or, on the sql side, something akin to:

update prod_users SET user_email = "asmith@foo.com" WHERE user_id = 82108;
update prod_users set user_name = "asmith";
