I accidentally removed the WHERE clause from my SQL query in a personal tool. Every row is now the same. I overwrote 206,000+ rows. I have no backup, I am stupid. (lemmy.world)

"UPDATE table_name SET w = $1, x = $2, z = $4 WHERE y = $3 RETURNING *",

does not do the same as

"UPDATE table_name SET w = $1, x = $2, y = $3, z = $4 RETURNING *",

It's 2 am and my mind blanked out the WHERE, and just wanted the numbers neatly in order of 1234.

idiot.

FML.

Yep. If you're in a situation where you have to write SQL on the fly in prod, you have already failed.

Tell that to my former employer...

Yeah, I swear it's part of the culture at some places. At my first full-time job, my boss dropped the production database the week before I started. They lost at least a day of records because of it and he spent most of the first day telling me why writing sql in prod was bad.

I genuinely think it makes more sense to write your own management system in a language of your choice rather than writing SQL by hand.

Of course, it makes more sense to just use one that's already out there. But still.
