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.

who thought it was a good idea to make the where condition in SQL syntax only correct after the set?? disaster waiting to happen

The people designing SQL, not having learned from the mistakes of COBOL, thought that having the syntax as close to English as possible will make it more readable.
