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. - eviltoast

"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.

    I have done this too. Shit happens.

    One of my co-workers used to write UPDATE statements backwards limit then where etc, to prevent this stuff, feels like a bit of a faff to me.

      I always write it as a select, before turning it into a delete or update. I have burned myself too often already.

        Oh I did that like a year ago.

        And then last night had an error that led me back near this code and stupidly thought “hey it’d look neater if those numbers were in order”
