"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"
